Planting Good King Henry

Good King Henry is a cool season vegetable in the Amaranthaceae family. Getting the timing right is the difference between a strong stand and a disappointing one, so the windows below are given relative to your own last spring frost and first fall frost rather than a generic calendar date. Look up your local frost dates and count back or forward from there.

You can sow Good King Henry directly into the garden 0–2 weeks before your last frost.

Good King Henry can be grown by direct sowing and transplanting. Direct sowing avoids transplant shock, while direct sowing is simplest where the season is long enough.

Good King Henry reaches maturity in 80–100 days from sowing.

Good King Henry is ready to harvest after about 90 days. Harvest before summer heat or, for fall crops, before a hard freeze, to keep quality high.

Conditions and Care

As a cool-season vegetable, Good King Henry does its best growing in the cooler weather of spring and fall and tends to bolt or turn bitter in summer heat. It is frost hardy and can shrug off light freezes, so it can stay in the ground later into the season than tender crops.

Good King Henry grows well in partial sun and tolerates some afternoon shade, which can help slow bolting in warm weather. Sow seed about 0.25 inches deep — small seed is sown shallow and barely covered, then keep the soil evenly moist until seedlings establish.

Good King Henry belongs to the Amaranthaceae family; rotating where you grow members of this family each year helps limit the build-up of soil-borne pests and disease. Good King Henry is generally grown as a single planting each season rather than succession sown.
