Trees and shrubs on a lawn

Tree surgeon’s ideas on harmony between trees, shrubs and lawn

 

There is something incredibly attractive about combination of trees and shrubs Trees lawn and shrubson a lawn, so You should try to grow some in your garden. Trees lend variety to a landscape making it more interesting in addition they provide shade, protect and attract birds to the garden. A tree or even a lone bush bedded out on a lawn become the visual center of it and distract attention from the monotonous green space. Another important strong point of trees and shrubs is that, when they strike root they do not need any special care.

 

Choosing locations for trees on a lawn

 

Perhaps the most difficult thing about choosing a tree is the necessity to decide in favor of one or two cultivars from the myriad of commercially available. Nevertheless, it should be done: one visible from all sides tree looks most impressive. If You still want to bed out several trees it would be much better to allocate them in one compact group and not to scatter them all over the lawn.

A lonely tree on a lawn looks quite picturesque, but choosing a suitable location can sometimes be difficult. Please remember carefully that You shouldn’t plant it exactly in the middle of the lawn as it will look unfavorable there. If you don’t plan to arrange the rest of the garden around the chosen tree, it may be better to put the tree near a border.

From some coigne of vantage, the house or patio, peer at the lawn and the space behind it. Do you see anything You would prefer to hide? Do the windows of the neighboring house look over your garden? Try to allocate the tree in a way to cover up an undesired view from the window and at the same time to hide You from strangers’ glances. Otherwise, if your garden has picturesque surroundings, two or three properly allocated trees will help to combine your site with the surrounding landscape. But in the city a tree standing on the edge of a lawn creates an illusion of vast landscaped areas hiding behind it, even if your property is situated on a dusty city street.

Nota bene

For those areas of the lawn where You want to achieve more natural look, cultivating tall grass, bulbs or wild field flowers, try to avoid using exotic or hybrid trees. Trees and shrubs need to look natural and thus more seamless.

 

Deciduous ornamental trees

 

For a small lawn You should choose a tree that will look attractive, if not the whole Ornamental tree and lawnyear long, at least most or some of it. It is rather insufficient if the chosen tree has just one decorative feature, such as  beautiful blossom, fruitage or autumnal coloring. Chinese sward (Cornuskousa var. chinensis) is an amazing tree, which will delight You with large white flowers at the early summer, with red fruits later and with crimson foliage in autumn. Furthermore, it has a beautiful scaly rind, and expands upward and outward equally well.

Many cultivars of crab-apple trees (Malus) blossom very beautifully as well, and later on please an eye with the view of fruits; they are most suitable for planting on small lawns. Trees of Sorbus cashmiriana are small and sprawling with dark green pinnate leaves, white flowers, and later on they yield pink or white berries.

Trees with interesting unusual foliage such as acer griseum, northern maple (acer pensylvanicum), paper birch (especially Betula utilis var. jacquemotii) and sakura (Prunus serrula) look great on a lawn as well. All these trees do not grow too fast, do not have very dense crowns (grass would love it), and they are not too big and therefore are ideal for lawns.

There are not many trees that could compare in beauty of autumn leaves with weeping maple (Acer palmatum), when its paw-shaped leaves turn scarlet. Many cultivars of cherry trees (Prunus), such as Okate and Sargent (Prunus sargentii), can also boast a bright autumn foliage and beautiful blossom.

To the most space-saving trees could be relevant willow-leaf pear (Pyrus salicfolia) with a round crown, silvery leaves and cream-colored blossom and its weeping sub-type Pendula, and acacia (Robinia pseudoacacia) Umbraculifera with beautiful leaves. Choose these particular cultivar if you want to have a small tree, because other representatives of the species are much larger.

 

Evergreen ornamental trees

 

Evergreen trees, especially those ones with variegated or golden-yellow foliage, contrasting with grass, also look very impressive on the lawn. Taxus baccata Fastigiata is a straight columnar yew tree with bright yellow foliage. It grows slowly and is well suited for the lawn, as well as Picea pungens Koster – a lovely peg-shaped fir tree with a silver-blue crown. Pinus sylvestris Watereri – is a low, slow-growing pine with hard blue-gray needles and broad crown.

You cannot go wrong if you choose for your lawn an evergreen Pittosporum tenuifolium Silver Queen – a space-saving tree with a round crown and a gray-green leaves with a white rim.

One of the best evergreen trees is an arbutus x andrachnoides it has beautiful reddish-brown rind, glittering green foliage, white flowers, interesting fruits and stretching up crown.

 

Soil  at the base of the tree’s trunk

 

When planning to plant a tree on the lawn, You should remember to cut the grass around the tree trunk and that in autumn the tree will shed its leaves.

Base of tree and lawnThe problem of cutting the grass could be solved by leaving all bare section of soil around the trunk. Just let it be wide enough to ensure that you will not damage the tree trunk while cutting the grass on the lawn with the mower. At first, whilst the tree is small, you may plant small items around the tree’s base, but as the tree develops it will become too dry for most plants as well as  tree foliage will serve as an umbrella blocking all the sunshine. You should choose the plants very carefully, should you still desire to plant them under mature trees.
Weeping trees with branches hanging to the ground, such as the weeping birch or cherry, growing alone on a lawn, look very graceful and very popular. However, due to their shape, they create a very dense shade, which, of course, adversely affects the grass growing under them.

 

Planting plants under trees

 

Trees with a lightsome openwork foliage are ideal for planting as subordinate crop since they permit light through in a proper way. Himalayan birch (Betula utilis var. jacquermontii) is especially good for this, as it has small-size and sparse foliage. However, most of the trees give a deep shadow, and therefore the choice of plants for planting beneath them is limited. The most reasonable decision in this case is planting spring bulbous cultivars, which are able to grow up and finish blossoming before dense foliage is being formed on the tree. Shade-demanding ground-cover plants feel very comfortably under such trees as well. If you grow evergreen trees on your lawn, it is likely that you’ll have to confine them to their own decorative effect.

You should not plant any bushes or large plants under a lonely tree growing on a lawn, as they will merge and distort the silhouette of the trunk of the tree, but different climbers would just decorate it. However, You should keep in mind that too strong and viable climbing plant can strangle a small tree and You should take that into account, while making decision.

 

Shade-resistant plants that could be planted under trees

 

Bulbous cultivars

Anemone;

Cyclamen;

Aconite also known as eranthis hyemalis;

Adder-grass or fawn lily, or trout lily, or dog’s tooth violet also known as eritronium;

Snowdrop also known as Galanthus;

Bluebell or eastern camass, or wild hyacinth also known as Scilla hyacinthoides;

Birthroot or wake robin also known as trillium.

Perennials

Anemone;

Astilbe;

Bergenia or giant rock foil;

Digitalis or foxglove, or finger-flower also known as deadman’s bells;

Common or wild hops also known as humulus lupulus;

Honeyberry or honeysuckle, or woodbine, or caprifoil, or button tree also known as lonicera;

Roses;

Indian cress or nasturtium also known as tropaeolum majus.

 

Shrubs on lawns

 

If You do not have enough space on your lawn for a tree, plant a bush, or maybe even two or three. Some bushes are stretching upwards and, if properly cut, will look like a tree with multiple trunks. A lawn is a perfect place to plant your favorite bush, so you’ll be able to admire it from all sides, and it will not have to fight with its neighbors for light, water and nourishment.

The same advantages and disadvantages are inherent for shrubs growing on lawns as for trees, with the only difference that they don’t have clear-cut trunks, which means that the foliage is much lower and grass suffers more from it. Two main problems you may encounter: grass can grow too high, because you will not be able to approach it with the mower, or it might simply perish in the dense shade. In the first case, a simple scissors could solve your problem. And in the second You’ll have to clean up around the bush trunk and either make it increasingly wider as the bush grows, or regularly cut the bush to keep it in the same boundaries. You should make the choice with due account to the type of shrub and its immunity to frequent pruning.

 

Ornamental shrubs for lawns recommended by our tree surgeons

 

Juneberry or bilberry, shadbush, or sugar berry, or service tree, or juice peer also known as amelanchier canadensis;

Cianotus Skylark;

Zante-wood or smoke bush, or Aaron’s beard, or common smoke tree, or wig-tree, or chittamwood also known as Cotinus coggygria;

Royal Purple;

Daphne mezereum or daphne balmy Aureomarginata;

Mock orange or syringe, or philadelphus belle etoile;

Pieris beautiful Wakehurst;

Arrowwood or viburnum, or white-rod, or guilder rose, or white hazel tree also known as raisin folded Mariesii.

 

Planting and fertilization

 

The best time for planting shrubs or trees is the period between spring and autumn and in some milder European countries may plant in winter though saplings can get damaged by sudden and prolonged frosts. Ornamental plants and bushes need other fertilizers, than lawn grass requires, so they should be fed separately. Grass requires fertilizers with a high nitrogen level for healthy and beautiful leaves, but for trees and shrubs such fertilizer also stimulates the growth of leaves at the expense of flowers and fruit. They need a balanced fertilizer with equal doses of nitrogen, potassium and phosphorus, but if they are going to blossom or the fruits are kerning on them a fertilizer should have increased level of potassium. You should put the fertilizer into the ground around the trunk using manure fork and irrigate it properly in a way that water would reach the root zone. Remove all the weeds from the area under the tree or bush.

If a fruit tree is growing on your lawn, You should either leave a wider clear space around the tree trunk or not fertilize the grass around the tree, otherwise you will soon discover that the tree bears much fewer flowers and fruits.

 

Leaves and leaf humus

 

Putrefying leaves emit a lot of heat, so they should be removed from the lawn in autumn, as soon as they fall off. Collect the leaves into compost piles. Leaves will gradually turn into leaf mold – an excellent soil conditioner for a garden. Leaves should be kept in those bags for at least six months, so put them somewhere away. Before storing, you should soak the leaves properly to aid decomposition.

 

How to apply fertilizer using a scatterer

 

Dig a planting pit in the soil about 1,2 meters in diameter. It must be at least four times wider than the diameter of the pot in which the tree grows or a soil clod surrounding the roots. First, remove the greensward and fold it in a stack, and then put the soil dug out from the pit in a wheelbarrow or on a sheet of plastic, not to spoil the lawn. The hole should be about one and a half times deeper than the pot.

If the compost around the roots is completely dry, submerse the pot in a bucket of water to moisten it through. Put some garden compost or any other organic fertilizer (for example, a couple of buckets of good humus manure) at the bottom of the dug pit. Inter-fuse it with the soil using a manure fork. Put some organics in the soil taken from the pit as well, as a tree should be planted not just into the garden soil, but in a moisture well-retentive soil mixture.

If the roots of the tree have completely filled the pot, stir them up a bit. Put the tree or shrub in the center of the pit so that the root clod would be placed at the ground level; add to the bottom some compost-soil mixture, if necessary. Fill the pit with soil and compost, tamping it carefully.

You should prop up trees with pegs for the first two years after planting them unless and until they take root well. Be careful not to damage the roots, hammer a peg into the ground at height of 1-1,2 meters over the soil level and at an angle of 45 ° to the ground, and close enough to the tree to snap it to the trunk. The top of the peg should be directed toward the prevailing wind. You should irrigate the tree or the bush abundantly – at least 2-3 buckets of water.

Winter tree pruning

Fruit trees surgery in winter

Temperature of air and soil are the overarching factors of growth and development of above ground and root systems of fruit trees. All of this needs to be considered when evaluating overall heath of the tree and before we start any tree surgery.

Plants handling in winter

Atmospheric temperature affects the chemical processes and movement of substances inside the plant, such as evaporation of water from leaves microbiological processes in the soil and so on. Not only a frost-free period of a certain duration, but also an appropriate temperature changing rhythm over the whole year are essential for the right development of plants. Consequently, gradual cooling during the fall time allows the trees to prepare for winter dormancy. Initially, at a temperature from 0° to 6° C, in plant organs large carbohydrates (e.g. starch) are transubstantiate to simple ones (e.g. sugar). Then, at a temperature from 0° to -12° C, when water passes from the cells to the inter-cellular spaces, a reserve of organic matter “for tough times” is forming. After that, the plant settles down into dormancy state. You should note that the deeper the plant’s state of relative calm, the higher its hardiness.
By the way, it is necessary to distinguish between these agronomic terms, as the frost tolerance and winter hardiness. You should keep all this information in mind selecting cultivars of fruit trees for the garden.
Frost tolerance is a peculiarity of a plant to adapt to the impact of low temperatures in a proper way.
Winter hardiness is an ability of plants to withstand the whole range of different winter conditions: a certain moisture level of soil, strength of wind etc. (Experts specified that cold-hardy cultivars of fruit trees are settling down into dormancy state much deeper than others.).
We recommend to pomiculturists to keep a diary of observations – to record all the change bits in fruit and berry plants life, as well as the terms and the nature of gardening.
Inclement winters, if not destroying fruit plants, but shortening its lives. But more often buds and branches are suffering from frost. Notably that it predominantly happens if the plants hadn’t been prepared for the winter in a proper way. For example, fruit trees have plentifully fructified and haven’t managed to save up enough spare substances, or ensuing a summer-autumn drought season have prematurely dropped all the leaves, or its foliage has been damaged by pests and diseases. To keep out of it, your garden needs a competent tree surgeon care which is the only way plants can make it through the winter safely.

Weather and Harvest

The growth of fruit plants is mostly affected by the temperature during the spring, especially in the morning.

The nutrient enrichment is mostly affected by the weather in mid-summer and autumn period.
Moderate daytime temperatures are exerting salutary influence over the processes of photosynthesis (enrichment with organic matter). Conversely, high daytime temperatures (e.g. such as were documented during the summer of 2010) are aggravating the performance of the leaves and enrichment with organic matter. Hence You get a notable shortage of the crop.
The fruits are ripening better on condition of the average temperatures in August and September are elevated.
The most favorable conditions for the growth of wood if the average temperature in late fall is lowered and in early winter it is close to 0°C.

Frost, warmth, heat

We can sort fruit plants by its particularity about heat to be arranged in such an order.
North Zone: rowan – bird cherry – cherry crab – berry crops.
Central area: apple – cherry – plum – pear.
South Zone: cherry – quince – apricot – walnut – pecan – hazelnut – almonds – peach.
Subtropical Zone: pistachio – chestnut – Eastern persimmon – figs – olive – feijoa – tangerine – orange – lemon – avocado.

Pruning young trees

Caring for young fruit trees

Caring for young fruit trees

If You got a garden of young fruit trees, You should take especially reverent care for the trees as they need constant careful attention. Of course, if You put enough necessary efforts the harvest will not take long.

Plants bed out during the last season may fail to strike root for various reasons. Besides, any shortcomings in bedding out frequently affect process of further rooting and growth of the trees. It’ll be much easier to rectify these deficiencies while your fruit trees are young.  This could also be a great time to do any tree pruning at this stage.
Firstly You should take up higher every too much sunken tree. For this purpose, You should dig a trench around the trunk at a distance of 35-40 cm from it with the same depth. Then two men carefully lift up the root ball with shovels, pouring under it the nourishing soil in order that the plant should be bed out at the correct level. Still You shouldn’t overdo it, as the root collar and the roots should not be bared.
The lean of a tree is another imperfection coming from not properly puddled soil in the landing pit after bedding out the plant. The fix of the problem is simple, until the tree hasn’t grown too much. For adjusting lean tree it should be carefully pulled in the right direction via tying it to a firmly driven stake.

To straighten crooked boles (trunks) or soboles a rail should be firmly tied to the bole at the sweep area. In the summer as far as the bole would be thickening to avoid constrictions the garter should be loosen. A sweep of the bole of young plants could be fully corrected for 1-2 vegetation season.

The circles around the tree bole

On condition of proper growth by the end of the first year the roots of a fruit tree occupy the entire area of the landing pit and expand even little beyond it.

Hereafter annual growth of the root system across the whole diameter could measure up to 50-80 cm. For this reason, in the second year after bedding out diameter of the circles around the boles of apple or pear trees are usually adjusted to 2 m. With the excrescence of the crown the around the boles should be increased annually.

Throughout the spring and summer the soil around the boles should be loosen with rake to a depth of not more than 5 cm in order not to injure the delicate suction roots.

While autumn leaf fall the soil in circles should be dug up with overturning of the furrow slices. For pome fruit trees – to a depth of 15 cm, for stone fruit trees – up to 12 cm, without breaking the clods. Near the bole soil should be dug up shallow. Alongside with digging You should make a mulch of manure and peat.

In spring the soil in circles around boles should be dug up, as early as possible, and no deeper than 6-8 cm, without overturning of the furrow slices. Then the soil should be well loosen, in order that there was no large clods. On the old, well-developed soils only loosening the soil in circles around boles restricted to a depth of 7-10 cm can be recommended.

Digging the soil in circles around boles is highly recommended to perform with garden fork as it less damaging method for the tree roots.

The soil in circles around boles needs to be weeded all the summertime long, in order it would not overgrown with weeds or lawn grass. To maintain moisture and good soil structure You should mulch it with peat or sifted compost in layers of about 5 cm.

Tree Pruning

Moisture

During active growth at the beginning of the summer the young fruit should be well watered. Depending on the amount of rainfall and the nature of the soil in the first half of the summer the trees should be watered from three to five times a day. In dry years, and at the south regions with a shortage of rain – up to seven – eight times or more.

Watering should be abundant, to wet the soil to a depth of at least half a meter. The average rate of quantity of water per square meter of the soil in circles around boles compiles about 2-3 buckets.

In the first year of bedding out for each watering of one plant 2-3 buckets of water should be diffused. Later on the watering rate should be increasing in the one-two buckets yearly. For a 5-6-year-old tree should be poured on average 7-8 buckets of water, and for a 8-10 year-old tree – 10-15 buckets of water. You should diffuse less water for the plants bedded out on light-textured soils, and on the contrary much more often for plants on heavy -textured soils.

In some years in the central and northern areas due to the abundance of moisture in late summer the growth of trees delayed, the wood didn’t grow ripen and perished from light frosts. To protect fruit plants, You should stop watering them in August and only in October, with the beginning of leaf fall, when autumn is dry You should proceed with supplemental irrigation – three buckets per square meter, evenly distributing moisture on the soil in circles around boles. For more information on tree pruning have a look at this great resource.
