With several over-90-degree days, including a couple of over-100-degree days starting next Monday, this weekend is the time to water deeply and have some shadecloth on hand. Since our garden plants and trees have been blithely growing with nary a day of harsh conditions until now, they’ll be shocked to suddenly have to endure these coming days. So, the more water and shade you can provide them ahead of time, the better they’ll be able to handle those stressful conditions when they occur.
Here’s how to help your plants survive the onslaught and continue thriving afterwards.
Plants Shut Down Above 100 Degrees
Hold Off On Planting Anything
Existing plants, whether already in the garden or still in their storebought containers, will be dealing with more than enough stress just making it through these several days of suddenly-hot temperatures, so no need to inflict even more stress by transplanting new plants. Do keep them in a lightly shaded area until temperatures lower and you can proceed with transplanting them.
Hold Off On Pruning Anything
Trimming is a shock to plants, so even if bloomed-out plants are shabby looking, leave them alone until the air temperatures lower back down into the mid-80s. When plants are comfortably growing again, do your light trimming.
Afternoon Is The Worst Time of Day
From about 2 to 6pm is the most intensely hot direct sun, so provide some protection to plants during that time.
