Not enough rain calls for creativity

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.
“Mow high,” she said. “The higher your mower is set, the deeper
the roots are able to go underground to access soil moisture.” Deeper turfgrass
roots equal stronger, healthier turf.

Water your crops and gardens as early in the day as possible.
When it comes to watering your plants, the earlier you can do it
the better.
“Don’t water any time but the morning,” she explained. “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, which is not good for their health. Watering in the morning allows
for moisture to be soaked up in the root zone before the sun is too high.
Mulch your garden beds.
This is particularly important for vegetable gardens. Mulch locks
in moisture in the soil and discourages evaporation.
“Making sure that the ground is covered by some type of mulch
that’ll hold the moisture is one of the best things you can do for your
vegetable plants. Most are annuals from other parts of the world and need
supplemental water every day in the heat of summer,” she said, “so anything you
can do to conserve it is good.”
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.
“If you look around the landscape, it’s the plants from Asia and
Europe that don’t do as well,” she said, “because they’re like, ‘where am I?’”
The types of plants that are best to plant vary from garden to
garden based on a variety of factors, including sun exposure, solid 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,
and more,” she said. “The more information you have, the easier it is to choose
plants that can tolerate the climate on your site. It’s a front end investment
that pays off in the long run.”
Venturini Hardesty said that, on average, New England tends to get
about 45 inches of rain per year. If the average rain per week is about one
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 explained. However, it’s never
too early to prepare.
“In some ways, a drought exacerbates a condition that already
exists during the summer,” she said, “so adapting to a drought by expecting it
is going to be one of the best defenses we have because I don’t think it’s
going away.”
Gardeners are encouraged to utilize the resources offered by the
Cooperative Extension to assist in the healthy development of their plants.
