How to keep your garden and home a shade cooler

With weather changes, it seems there are more hot spells and we tend to go racing to hide indoors with the dry, artificially chilled air pumped out by our air conditioners. Sometimes we get so used to efficiency and high tech that we forget some solutions are simple and have been around for a long time. One cooling example is planting a tree. Trees are the most Eco-friendly, long-lasting and beautiful way to make your home and garden cooler in heat. They will provide shade to your garden and the shade will grow year after year as your tree matures.

Trees are nature’s sun (and rain) umbrellas. They have been the most reliable solution for staying cool since civilization began. There are many different kinds of trees that can add color and form – even flowers, fruit or nuts — to your landscape. In hot summer areas even the wildlife knows to seek the shade of a tree, and in cold winters, deciduous trees (those that shed their leaves) allow warming sun to penetrate. Planting a shade tree to lessen the heat of summer sun directly on your house can even save you about ten percent on your air conditioning bills. Whether you want your tree to turn colors in the autumn, put on a show of blooms, underscore a theme garden, be a romantic location for seating or picnicking – or be used for any other purpose — here are some tips that will help you grow the best shade tree possible for your yard.

Plan ahead. Look at the space where you want to plant your shade tree. Take into consideration the time of the year and how shadows will move. Plant your tree where the shade will be of most benefit at the hottest time of summer. (Tip: the south and west facing sides of any structure will receive the most intense sunshine.)

Keep in mind how your chosen tree will grow, look and behave. When a young tree is planted it will be small and compact, but it may look much different when it matures. Sometimes even the shape of leaves change as the tree ages. Do your research so you know what your tree will look like in the future and plant as if the tree were full size. Ask yourself some questions. Does your location have shade or sun? What kind of soil or drainage does your planting area offer? And can the space you are planting accommodate both the overhead span and the underground root system of the tree you want to plant when it reaches its mature, full size? Planting the right tree in the right spot will make for a healthy, happy and low-maintenance asset to your garden, while providing the best shade-cover possible.

Decide if you want deciduous (trees that drop their leaves in the autumn) or evergreen. Not only are the looks different but care will vary. All trees shed their leaves but the deciduous ones do it all at once. Litter can be a consideration. If you are planting a tree near a swimming pool or a pond, you will want minimal leaf and flower drop. Trees will always shed leaves, flowers, seeds and bark, but some are more prolific than others. Heavy-flowering trees, large petals and large leaves will create more litter. Even evergreen trees can create a lot of litter. Pines are particularly generous at dropping needles. So select trees for these areas that will create the minimum work to keep clean. Also beware of flowers and fruit that can be sticky or stain where surfaces below can be damaged, like parked cars, seating areas or walkways you want to keep clean.

Some trees offer a choice of fruiting or fruitless varieties like the mulberry or olive tree. Some offer sweet scents and fruit like citrus trees. Fruit trees and flowering trees can put on brilliant shows of colorful blooms. Some trees turn blazing colors for an autumn show. So long as these trees grow tall enough, they can all keep you cool in the heat of summer. Smaller trees can be planted in small groups to cast more shade.

Plant your young tree in the right location and keep it well watered. Most trees don’t like to be kept wet just on the surface so make sure moisture reaches the lowest roots.

If you select a tree that will grow well in your garden space and guide its growth by judicious pruning, it should grow into a sturdy, low-maintenance source of shade. A well-planted shade tree will make both your home and garden more comfortable for you, your family and your pets. It will also help clean the air of pollutants, attract birds and butterflies and add beauty to your property. Planting a tree improperly can become a very expensive – even dangerous – problem in the garden. So start off right and your landscape can keep your life a shade cooler in hot weather. A happy, healthy shade tree can become one of your best landscape investments.

How to Plant New Trees and Shrubs

The larger growing residents of the garden are your trees and shrubs. The bigger they are, the greater the job. Planting while deciduous plants are dormant or evergreens are semi-dormant is the best time since there will be less stress and any cuts or damage will bleed less. Careful planting can be done for most, however, at any time of the year so long as the soil is not frozen. Here are some tips on how to plant bare-root or potted trees and shrubs.

Before even starting to plant, remember that large shrubs and trees will grow big, so carefully chose the right location for planting. Visualize your tree or bush at full size and plan accordingly. Then you can get to work preparing the site.

With bare-root trees and bushes you will unwrap the root ball, shaking off any sand, sawdust or other material that was used to moisten and cushion the roots. Then place your tree or shrub in a pail of water to soak the roots while you prepare your hole for planting.

Dig a hole so the bottom will easily accommodate the depth of the roots. Do not plant your tree or shrub too deep – check for the soil line on the stem just above the roots. Usually you can see where the previous soil level was. Dig the hole a minimum of twice the width of the spread roots. You are always safe with a wider hole since the loosened ground will encourage the roots to spread into surrounding soil. If you are planting a balled or potted specimen, still dig the hole wide while leaving the bottom the same depth as the root ball so it will sit solidly on the base of the hole and match the top of the soil levels. If you are going to add amendments to your soil, this is a good time to do it.

The question of amendments has no simple answer. If you are planting a local native tree or shrub, leave your soil be: your conditions are exactly what your native will want. If you are trying to adapt a tree or shrub that needs the extra boost of amendments, one school of thought is that you should add your additions by mixing it with your native soil for a two to four foot radius around the center of the hole to help the transplant get established. The other school of thought is that you should avoid amendments altogether and allow your plant to adapt to the native soil since amendments will eventually melt away in time, anyway. The choice is up to you.

If your soil is dry, you may want to water the newly-dug, empty hole before planting. By letting the water sink deep below the roots of your new arrival you are inviting the first growth to continue in a downward direction rather than out to the sides. If there has been recent rain and the soil is already moist at the bottom of the hole, you can probably skip this step.

Place stakes on either side of the new plant before filling the hole when planting small trees that may be vulnerable to strong winds. Set in your new plants and fill in empty areas. Tamp down the soil firmly and sculpt a circular moat that traces around the perimeter of the hole so water fills the trough and seeps down in the hole for a deep, thorough watering. Many trees and shrubs will benefit from a very light pruning after being planted. Clip off any damaged or crossing branches and, especially with fruit trees, trim back the branches four to six inches.

With the tree planted and trimmed, you are now ready to tie your tree to the support stakes if you are using them. Don’t tie branches or trunks directly against the supports where they can rub and become damaged. There are several different styles of tree ties you can buy that will allow for at least a few inches between the tree and the support post. Space not only avoids abrasion damage, but it allows some motion in winds. A little motion will encourage your tree or large shrub to develop strong roots; something you want to encourage to make sure it can resist heavy winds in the future once you remove the supports. Usually a single year of support is all you will need. If the tree is in a particularly windy exposure, two years is fine. Try not to leave supports on for more than two and a half years. You don’t want the root system to become so dependent that it doesn’t develop thoroughly. Also keep an eye on any bindings. If you see the tension become tight on the bark, loosen it so you don’t strangle the tree or shrub.

Keep your new trees and shrubs well watered during the first year or two to make sure roots spread out and grow in a healthy manner. Then the frequency of watering will be determined by the type of tree or shrub. Depth of watering is more important than frequency. A well-rooted woody plant can take a lot more dry if the soil deep down is moist. A plant that has moist topsoil but is dry further down will not develop the strong root system it will need to thrive.
