High heat spells such as the one we had last month can exert a devastating effect on gardens, but as many of us learned, it’s far worse during a drought. And worse yet when the gardener is away and the irrigation system fails, as I experienced.
In my case, the only real loss was the last of the lettuce. Tomato vines perked up as soon as drip lines were turned on, and shriveled green beans didn’t matter as soon as new beans took their place.
I could have lessened this minor damage had I laid down deeper mulch around these few vegetables. Those in other beds as well as all shrubs and perennials were better protected.
Drought, like any kind of strife and strain, can teach us lessons that we don’t learn during prosperity. When water is limited, the corollary is that plants are limited, or at least should be. The more plants in a bed, the greater the root mass vying for moisture. By reducing the number of plants, those remaining benefit.
Water-hungry vegetables, particularly those with large leaves, want more water than some of us have available this year.
My wilted squash and bitter cucumbers have told me that I should either give them more water or give up on them.
Their drip line is now turned off and the deep-rooted parsley and sage in the same bed are on their own.
Normally it’s a difficult decision to remove plants from a garden, but when some are struggling to survive with little relief in sight, it’s time to make changes.
I’ve removed a dwarf Chinese fringe flower shrub (Loropetalum chinense), one that I coveted then coddled for over a year, but it simply couldn’t make it with reduced irrigation. It came out along with a few stressed roses that suffered from blackspot and needed more than water.
