Keep harvests picked
Spring plantings are peaking — picking frequently keeps plants like tomatoes, beans, and squash producing instead of shutting down.
Water deep, mulch thick
One deep soak beats daily sprinkles. Two to three inches of mulch cuts evaporation and keeps roots cool through the hottest weeks.
Order fall seeds now
Fall varieties sell out in late summer. Ordering during the rest month means seeds are on hand the day your next window opens.
