Tips to Keep Gardens Alive During a Drought
August 1, 2022
For backyard gardeners, mild droughts and water ban restrictions common during the summer can be a cause for concern. Kate Venturini Hardesty, a program administrator and educator with the University of Rhode Island’s Cooperative Extension, offers some tips for gardeners who are feeling the heat.
Let your lawn rest.
“Your lawn is on summer vacation,” she said. “Lawns are meant to go dormant in July and August. Many turf types are perennial species, so they rely on a break, much like the herbaceous perennials in our gardens. When we don’t allow them to rest, they’re weaker, just like you and I without a good night’s sleep. Refraining from watering the lawn saves a tremendous amount of water.”
While this may mean that your lawn is brown instead of a vibrant green, it will be beneficial for its overall health.
Don’t mow your lawn too low.
Mowing your lawn too far down will also have a negative impact on it. You don’t want to be the golf course of your neighborhood — the taller your grass is, the healthier it will be.
“The higher your mower is set, the deeper the roots are able to go underground to access soil moisture,” she said.
Water your crops and gardens as early in the day as possible.
“Don’t water any time but the morning,” she said. “It gives the plants some time to actually absorb the water before it evaporates.”
If you water at noon, you’ll lose a bunch of water to evaporation. If you water in the evening after the sun has set, you run the risk of causing fungal issues for your plants.
Know what plants are best for your garden.
When it comes to designing and planning your gardens and landscaping, it’s critical that you know which plants are the best suited for your space. Plants that are native to your area will generally do best because they evolved and are able to adapt to the way your local climate is changing on both the micro and macro levels.
The types of plants that are best to plant vary from garden to garden based on a variety of factors, including sun exposure, soil health, and drainage. Before you plant, do your research.
“A simple site assessment exercise can help you gather information about available sunlight and water, wind exposure, drainage and soil health,” she said. “The more information you have, the easier it is to choose plants that can tolerate the climate on your site.”
Venturini Hardesty said that, on average, New England tends to get about 45 inches of rain annually. If the average rain per week is about an inch, that leaves about seven weeks without rain, which happens to be almost the full length of the months of July and August.
The shifts that climate change will bring to backyard gardeners – and crop growing and planting as a whole – will need to be dealt with on a regional level, not in individual backyards, she said.
