Is it safe to plant in the summer? We hear this question often, and the answer is usually “Yes!” but with some caveats. Here are some tips for successful summer planting.
The first thing to remember about summer planting is the difference between planting and transplanting. Planting is removing a plant with an intact root system from its container and placing it in the ground. The roots can be loosened and possibly lightly scored or trimmed but generally fill the container and transition easily. Transplanting, on the other hand, is when an existing plant is dug up and moved to a new spot. This often requires severing the roots, which can affect the plants ability to take up enough water during hot weather. Transplanting is best done in fall or early spring when the plant is dormant.
So, how is summer planting done? As with so many things, timing is everything. Waiting for the cool of the evening is best as the plant has all night to settle in. Early morning is also a good time, being the coolest part of the day. Be sure to water and drain the planting hole in advance of planting time, as well as watering the plant container. A fully hydrated plant is better able to transition to its new home. We also recommend a final watering with B-1 solution to help with root production and prevent transplant shock.
Once your tree, shrub or perennial has been properly planted the next step is to keep it watered. How much water is the critical issue and that depends on a few factors. Soil type determines how quickly water moves through the soil. Clay soil drains slowly while sandy soil drains quickly, thus sandy soil needs to be watered more often than clay. All soil types benefit from a layer of mulch at the base of the plant to maintain soil moisture while keeping the roots cool.
The size of the plant affects how often it needs to be watered. Generally a smaller plant needs to be watered more often than say, an eight foot tall tree. Check the soil with your finger or a water meter to see if the top 2-3 inches of soil are dry. If so, water enough to moisten the whole rootball, not just the surface. Remember that lawn sprinklers are not adequate for most plants because they are not on long enough to water trees and shrubs deeply.
Low humidity and wind can cause a plant to transpire (lose moisture through its leaves) more quickly, necessitating the need for more frequent watering. Be sure to check on new plantings when the hot, dry summer winds blow.
So, why not wait until fall to plant? Even though it is a little more work to summer plant, you are getting a head start on root production and establishment. Also, plant selection is much better in summer. Fall sales are great, but you might not always be able to find what you want.
