Hello, this is Donna Teasley, horticulture agent with the North Carolina Cooperative Extension, Burke Center.

As the heat of summer settles upon us it is important for gardeners to be aware of the effects that this constant steamy weather has on gardens, both vegetable and flower.

Extreme heat makes it necessary to increase water and to provide cooling mulches for plants, especially those in containers. At this time of year, container plants need water every day and in some cases, twice a day. Insufficient water might not kill a container plant but you’ll see a distinct absence of flowers. Plants that are struggling for water don’t have the energy to grow flowers.

Flower gardens are in better shape although they need regular water also. Thorough watering a few times a week is usually sufficient to keep flower beds looking good but mulch will be a big help in conserving moisture and keeping roots cool. Mulch is also great for weed control.

Vegetable gardens need an inch of water per week to produce crops. When summers are dry, which they mostly are, gardeners need to water. Inexpensive soaker hoses work great and are an efficient way to water gardens. Know that vegetable plants also need sufficient water to produce flowers which in turn produce crops.

So, when it gets hot, water early and water often. That’s the gardener’s key to success!
