plant care in extreme heat


Most plants suffer when temperatures rise above 95 degrees. Heat stress is evident in plants when leaves begin a "wilting" process. If ignored, the plant will continue to decline. Leaves will become "crunchy, turn yellow or will drop. Some plants, like many trees, will shed their leaves in extreme heat as an attempt to conserve water. Vegetables, especially tomatoes, squash, peppers, melons and cucumbers, will stop producing and usually drop their blossoms. Blossom-end rot is also common in hot weather.

Thorough, deep watering is critical during this time. For newly planted trees and shrubs, even the recent rain is not enough to reach deep into the new roots. Take some extra time and hand water plants thoroughly, making sure the soil is moist at least 3-4 inches below the surface, to ensure the plant is getting adequate water.

Set up a triage system of watering, centering on newly planted trees and shrubs first, and then established trees and shrubs, perennials, vegetables/annuals and finally, container plants. Perennials can be pruned, cutting blossoms and stalks. This gives the plant a rest for a resurgence later in the season. Install a shade structure over your vegetables to protect them from the heat, and water your container plants DAILY, watering until saturated, waiting, and watering again. For Blossom-end rot, try Ferti-lome's Yield Booster. Lawns naturally go dormant this time of year, so they should be the last in the watering triage.

Remember, this heat will not last forever and soon we will be wondering where it went.


  • You CAN plant container-grown perennials, shrubs and trees this month. Take the time to properly prepare your soil by amending it with composted cow manure, soil conditioner and by adding BioTone Plant Food. Once planted, make sure you understand the watering requirements of your plant.

  • Spring flowering perennials can be divided either this month or next month. Be sure to do this in the coolest part of the day and water the plants thoroughly after transplanting.

  • Prune your hybrid tea roses in late August to promote the most fall blooms. Remove about 1/3rd of the center of the plant and any weak or spindly canes. Maintain fungicide and insect control.

  • Keep weeds pulled, before they have a chance to flower and go to seed again. Weeds in the garden are harmful because they rob your plants of water and nutrients, and they harbor insects and diseases.

  • NOW is the time to start your fall and winter vegetables! Plant starters or seeds of green onion, carrots, beets, lettuce, spinach, radishes and winter cauliflower directly into the garden this month.

  • Apply lime to your cool season grass in preparation for aeration and over-seeding next month.

  • Make sure you schedule your aeration and over-seeding NOW to ensure you will have this done in a timely manner for September into early October. Routine lawn aeration/over-seeding is necessary for our clay soil.

  • If you keep Poinsettias and/or Christmas cactus, now is the time to bring them back indoors to prepare them for holiday flowering. Poinsettias need to be kept at 65-70 degrees and subjected to at least six weeks of 14 hours of total darkness per day and a minimum of 4 hours of direct light. Apply a good fertilizer now. Christmas cactus require the same general care, but they need temperatures of 50-60 degrees.
