Zone 6A Planting Calendar — April 18 to October 14

Row cover adds frost protection, speeds early growth, and physically excludes insect pests without spraying. Look for spun-bonded fabric with a stated weight and frost rating, UV resistance, and enough width for hoops or low tunnels.

Raised beds improve drainage, let gardeners control soil from day one, reduce compaction, and make gardening more accessible. A quality kit should use rot-resistant, food-safe materials and provide enough depth for productive rooting.

Every gardener benefits from putting water at the root zone instead of on the leaves, because drip and soaker systems reduce foliar disease pressure by limiting leaf wetness and soil splash. A quality kit should include a backflow preventer, filter, pressure reducer, and UV-resistant tubing.

University of Maryland Extension says most gardeners prefer staking, trellising, or caging tomatoes because it uses less space, reduces fruit rots, makes harvesting easier, and increases yield per garden area; Clemson Extension adds that cages improve air circulation and reduce disease spread. For indeterminate tomatoes that keep elongating and setting fruit all season, a heavy cage is a structural need, not just a convenience, because it keeps foliage and fruit off the soil while supporting continuous vertical growth.

UMN Extension recommends plastic mulch to warm soil for heat-loving crops and reports that red mulch has improved tomato yields by changing the quality of light reflected into the canopy, while black mulch also warms the root zone and suppresses weeds.
