Tomatillos are related to tomatoes, which are in the Nightshade family. They are similar in shape but are ripe when green, yellow, or purple and have a husk around the fruit. The fruits are borne on warm season plants, from inside the husk. You can tell when to pick a tomatillo by watching for the husk to burst. Growing and harvesting tomatillo fruits will enhance your culinary range and provide nutrients and variety to your diet.
Plant tomatillos from seed in warmer climates or start them indoors six weeks before the last expected frost. Tomatillo harvesting typically begins 75 to 100 days after planting.
Choose a full sun location with well drained soil. The plants require even moisture, especially after fruits begin to form. Cultivation of tomatillos is similar to that of tomato plants.
The plants need a cage or heavy staking to prevent the laden stems from laying on the ground.
