In any manor there are always places where trees or a house create a shade, which can be open-work or change its place during the daytime. In such places it would be great to plant shade tolerant trees or some other small trees. Shade tolerant flowers look amazing beneath the trees.
The best representatives (judging by ornament or shade tolerance) are cornel, smooth hydrangea, alpine currant and yew tree. All these plants are very beautiful, grow on the vast territory of the country and can grow in warm and cool climatic zones. These plants perfectly endure cutting and cropping which allowing for forming a tree with a various head form. All these plants are more or less shade tolerant, and yew tree is heliophobic. Based on the example of a decorative cornel we can tell how to plant a shade tolerant tree and create optimal conditions for blooming.
Decorative cornels can be both trees and bushes, which are no less decorative. But all of them like open-work shade. Cornel blooms in spring; its blossom is white or pink. In summer it is covered with bright red berries. In autumn cornel is also decorative as its foliage acquires all shades of the red color. Cornel is an unpretentious refined tree, which has an extensive area of habitat. Short-growing cornels and cornel bushes can be grown in climatic zones from 5 to 9. Some shade tolerant cornels, for example Cornus florida nana, grow to 15-20 feet in height. Cornus canadensis grows to 12-15″ in height and can be used as a ground-covering plant.
There are 5 pieces of advice that will help you to plant shade tolerant trees.
1. Choose an appropriate place for planting.
Pay attention to the fact that any tree grows not only in height, but its head branches out up to 20 feet in diameter.
2. Soil preparation.
Cornel is thought to be soil-unpretentious. Soils can be rocky or from forest-steppe or forest zones. Cornel doesn't like acid soils. It blooms well on light fertile soils.
Dig a hole. If you do not know soil constitution of your garden, before planting a tree mix the taken from the hole soil with decomposed or artificial manure, if necessary.
3. Prepare a hole for planting.
The diameter of the hole should be about 5 feet. The depth of the hole should be at least 2 feet. It should have a depth enough for the transplant roots not to reach the bottom of 8 inches.
4. The choice of a plant.
Depending on the place of planting, choose a thing that would satisfy you with its parameters. Cornel family is very wide. That is why there are some sorts of shade tolerant cornels which grow up to 30 feet or even more, and there are small cornels which are up to 6 feet. There are also cornel bushes. Besides, the plants have white or pink blossom according to the sort the plants. The fruits are bright red or dark vinous. When you choose a cornel transplant, it is desirable to buy it in a container with a slice of its native ground. Cornel is a symbiotic plant. Thus, the root system should grow in its florula that develops on the cornel's roots in the usual conditions. The plant should be well-developed, without bruises and rottenness.
5. Decorative cornel planting.
8 inches of prepared organic soil should be put into the hole. Then lower a transplant into it. The slice of soil with the plant roots should touch the ground. Then fill in the hole with the rest of the soil layer by layer. Firm every layer carefully. When the hole is fully filled in water the plant. When the soil sinks the bud union spot should be 1-1,5 ″ above the ground.
6. Handling of cornel.
The plant roots need air. Because of this you should hoe over the ground near the plant regularly. Cornel is not only a shade tolerant plant, but a drought-resistant plant as well. After planting, water the plant from time to time as deap as the plant pan dries.
Limit watering, when the plant naturalizes and spindles up. A cornel needs to be watered only in drought. It is recommended to mulch the ground around the cornel in order for avoid overheating of its roots. But the mulch shouldn't touch the tree stem as it will cause rotting.
In above shown way you can plant any tree or bush. However every tree and bush demands special soils and conditions for growing and blooming.
Other trees and bushes for shade.
Hydrangea grows well on fertile and slightly acid soils. Regular extra nutrition allows growing a showy tree or a bush with large leaves and huge inflorescences, which decorate it through the most part of the season.
Alpine currant is an unpretentious bush that doesn't require regular watering. It can withstand droughts and humid soils. It grows slowly and endures cutting. It can be an object of topiary art. You can make a quick set hedge or grow a tree from it.
Yew tree likes deep shade. It will feel well under the cover of big tree heads. Yew tree likes protected places. The root crown of the yew tree should be situated on the ground level. Depending on the sort of yew trees that grow on sub-acid, neutral and even mildly alkaline soils, the ground under yew trees, unlike cornels, should be pronged during the first 2-3 years.
