Zone 3 in June
June in Zone 3: Starting Fall Crops While Summer Is Still New
Fall cabbage and broccoli need an indoor start now
It feels early, but fall-season broccoli, cabbage, and the other brassicas on this month's table need only 5 to 6 weeks indoors before they transplant out later in summer, and starting them any longer than that just breeds the stressed, root-bound transplant that buttons instead of heading, well before your first frost near mid-September closes the window down. Start seed under the same lights you used for spring starts back in February.
A second potato planting listed as unique to this month is a small hedge, not a full crop: tuck a few seed potatoes into a gap in the bed to catch a fall harvest, understanding that a short season leaves this crop racing the clock from the start.
Water depth matters more than water frequency in full heat
Tomatoes, squash, and corn planted earlier now need roughly 1.5 inches of water a week, delivered in 2 deep soakings rather than daily light sprinkling. Push a finger 3 inches into the soil after watering, and if it comes out dry, the water did not reach the roots that need it.
Mulch every bed that is not already covered with 2 to 3 inches of straw or grass clippings. That layer alone can cut soil moisture loss by roughly a third during the hottest stretch of a season here, which usually peaks in late summer.
Check tomato and pepper leaves for the first sign of blossom end rot on developing fruit, a dark leathery patch at the bottom end. Uneven watering is the usual cause, so a consistent soaking schedule fixes more of these cases than any calcium spray from the garden shelf.
