Zone 4 in April

April in Zone 4: The Month Warm Weather Tricks People Into Rushing

A warm week in April is not the same as warm soil

This zone often gets a real stretch of 60 and 70 degree afternoons by mid-month, warm enough that gardeners a zone or two colder would already be celebrating, and that stretch talks a lot of people into transplanting tomatoes 3 or 4 weeks before it is safe. Air temperature and soil temperature are 2 different numbers, and soil 4 inches down can still sit near 45 degrees under a warm afternoon sky.

Check soil with a thermometer before trusting the thermometer on your porch. Tender transplants set into soil below 55 degrees commonly stall for 2 to 3 weeks rather than dying outright, which quietly erases the head start early planting was supposed to buy.

Kale, endive, escarole, and watercress are genuinely new this month

All four are unique to April here, meaning this is their real opening, not a continuation of something that started earlier. Watercress in particular wants consistently damp soil, closer to a bog than a bed, and will sulk or bolt fast in anything that dries out between waterings.

Direct seed kale and escarole shallow, no more than a quarter inch deep, and keep the top inch of soil damp until germination, which typically takes 5 to 8 days for both in soil at this point in the season.

Endive needs a slightly different hand, since its leaves turn bitter fast under stress. Keep it evenly watered rather than letting the bed cycle between soggy and dry, and expect the first outer leaves to be ready for a light harvest within about 6 weeks of germination.

April in zone 4: common questions

What can I plant in April in zone 4?+

In April, USDA zone 4 gardeners can sow Snap Pea, Potato, Cilantro, Parsley, Lettuce, leaf, Lettuce, romaine, and more. Dates use typical zone 4 frosts, so your own microclimate may shift them by a week or two.

What USDA hardiness zone am I in?+

Zone 4 is one band of the map, but planting time is set by your local frost dates, not the zone number. Enter your ZIP code in the free planner and it uses your actual frost dates, which can differ by weeks within a single zone.

Are these April planting dates exact?+

They are typical zone 4 windows. Two gardens in the same zone can be a week or two apart because of elevation and local climate, so treat these as a starting point and tune them to your ZIP code with the free planner.
