August is right around the corner and although it seems we’ve had adequate rain this summer, some plants are already showing signs of fading in the summer sun. What can you do?
I’d invite you to read a post Hans wrote awhile back that does a great job of explaining what happens to your plants in the heat called Heat Tolerance for Your Plants.
He lists a few things you can do:
- Select varieties suited to high heat
- Shade plants
- Apply a foliar shade film
- Mist plants to provide cooling
- Mulch around base of plant
- Adequate irrigation at all times
- Amend soil salts
- Apply Great Big Plants
I also found an article from the University of Arizona (talk about your hot, dry heat) in which the author, John Begeman shares his thoughts on reviving summer stressed plants.
I like his first piece of advice:
Don’t waste time nursing plants back that are too far gone. How do you know? If leaves are scorched brown and stems and branches are dry and brittle, it’s too late. Probably the plant was in the wrong place. Moisture loving plants in dry places, shade loving plants in sunny spots all spell disaster.
How many hours have we wasted trying to save a plant that really was beyond saving? He suggests that before you pull out scorched plants, check the stems and brances for life.
Scratch the stems with your thumb nail starting at the ends and moving down to the plant base. If the scratching reveals brown, dry wood, keep moving down the stem. When you reach live wood, it will be green or cream colored and moist. Cut these dead branches off, just above a side branch, side shoot or dormant bud.
He also reminds that pruning encourages new growth.
John recommends preparing a special mixture for the soil as well:
For soils that have become hydrophobic, sheading water, apply a mild soap solution. Mix up a teaspoon of liquid dish washing detergent in a gallon of water. Use this solution to wet the soil. The soap breaks what’s known as surface tension of the soil. This is what repels water, causing it to shed off without being absorbed. One application is enough. Once the soil has been wetted, it should be kept moist.
What do you do to revive summer over-heated plants?
