The soil in raised or sloping beds that face the sun will warm up quickly in spring, offering ideal conditions for early crops or flowers. If the soil in this area is free-draining then the place can be used for plants that prefer dry conditions.
South-facing fences and walls are excellent places to grow tender climbers, wall shrubs and trained fruit trees. Since they are in the sun for much of the day, this improves the flowering and fruiting. Walls absorb a great amount of heat during the day that is then released overnight. This can confer a few degrees extra frost protection during winter.
A row of trees or on fence will provide a sheltered area for plants that might otherwise suffer from wind damage. The growing conditions on each side of such a windbreak will be different. The ground close to a hedge or fence on the leeward side will rarely receive rain and will also be sheltered from the warming effect of the sun, depending how dense the windbreak is.
In the garden, areas of shade beneath tree canopies, hedger or large shrubs will receive the same sort of light as in natural woodland. These places may be suitable for plants that enjoy such an environment. If you are going to grow plants that will require a greater degree of shade, than you can grow them against north-facing walls, but keep in mind that these sites will also be colder.
A bog garden
For moisture-loving plants you can find the proper place to grow them near the edges of a pond or stream or in a low-lying part of your garden. In these places you can create the bog-like conditions in which moisture-loving plants will thrive.
Greenhouses and frames
To be able to provide a variety of microclimates in a small place, the gardener can use greenhouses, frames and cloches to obtain complete control over the nature elements. Using these structures the gardener is able to control the temperature, the amount of water, the air circulation, the amount of light that plants will receive and the type of plants that he wants to grow, as these structures allow you to grow even the most tender plants that otherwise will not survive in outdoor conditions.
