Physalis ixora) are part of the nightshade family, like tomatoes and eggplants, but they are more closely related to the Chinese lantern plant. However, tomatillo plants produce round edible fruits—usually 2 inches or smaller in diameter—that are covered by a papery husk, known as a calyx. Most tomatillo fruits are light green, but some varieties can also be purple or yellow when they ripen. Tomatillos are the star of the show for salsa verde, and are also used for soups, salsas, chilis, salad dressings, and grilling meats. Here's how to grow tomatillos in your garden. Tomatillo Overview Genus Name Physalis philadelphica syn. Physalis ixora Common Name Tomatillo Additional Common Names Mexican husk tomato, husk cherry, Mexican ground cherry, jamberries Plant Type Annual, Perennial Light Sun Height 3 to 4 feet Width 3 to 4 feet Flower Color Purple, White, Yellow Foliage Color Blue/Green Zones 10, 9 Propagation Seed Where to Plant Tomatillos Plant perennial tomatillos in an area that receives lots of sunshine. You can plant them directly in the soil, raised beds, or a big container. These fast-growing plants like well-draining soil with plenty of compost mixed in. Except for the ripe fruit, all parts of the tomatillo are toxic when consumed. How and When to Plant Tomatillos Sow tomatillo seeds indoors six to eight weeks before planting time. Transplant seedlings outdoors after soil temperatures are around 60°F. Tomatillos take about three months to grow, so plan accordingly. Plant at least two tomatillo plants near each other to ensure pollination. These plants need ample room and grow; plan for the mature plant to reach about 3-4 feet tall and wide. Tomatillo Care Tips Tomatillos are low-maintenance plants as long as their basic needs are met. Light Tomatillos need full sun, so plant them in a south or west-facing area for maximum sunlight daily. Choose an area that receives at least six hours of direct sunlight each day. Soil and Water Tomatillos grow best in well-draining soil with a pH of 6.0 to 7.0. Amending soil with organic matter, such as compost, adds essential nutrients and creates a more loamy soil. Water tomatillos at the base where the stem protrudes from the soil line. Avoid overhead watering so the leaves don't get wet, which can encourage plant disease problems. Tomatillo plants need around 1 to 1.5 inches of water each week. The 8 Best Soaker Hoses of 2024 for a Thriving Garden Temperature and Humidity Tomatillos do best when temperatures are around 70°F or higher during the day, and don't drop below 55°F at night.

Plant These 7 Perennial Vegetables to Get a Harvest Each Year Fertilizer Fertilize the seedlings before planting them in the garden with a liquid fertilizer at half strength, following the product directions. After they are transplanted, sprinkle one tablespoon of 21-0-0 fertilizer near each plant monthly. Don't overfertilize tomatillos because this delays fruit production and causes leaves to overgrow. Pruning Pruning tomatillos isn't necessary. You'll likely need to stake tomatillo plants like you do tomato plants. Pests and Problems Tomatillos are hardy and resilient plants. Powdery mildew, a fungal disease, can spread and cover the foliage, and overwatering can lead to root rot. Aphids and flea beetles are also common pests for tomatillo plants. Flea beetles munch on the leaves, leaving tiny holes. Aphids leave secretions, so check leaves for wet, shiny, or sticky residue. How to Propagate Tomatillos The most common way to propagate tomatillos is by seeds. When tomatillo plants finish their life cycle and go to seed, gather the seeds, dry them, and store them in a glass jar in a dry, cool, and dark place. Start the seeds indoors for the following season, allowing six to eight weeks for transplants to be ready to go into the garden when the weather warms. How Long Do Seeds Last? Plus How to Tell If Old Seeds Are Still Good Harvesting Tomatillos Tomatillos are ready for harvest when the fruit fills in the husk. Sometimes, the husk splits as the fruit spills over. Husks also provide a clue; they turn from bright green to a light brownish color when the fruit is ready. When tomatillos begin to ripen, check them a couple of times a week to know when it's time to harvest. The fruits should feel firm to the touch. Use them within two to three weeks of harvest. The word tomatillo means 'little tomato,' which is fitting because they're often used in similar ways. 14 Taco Salsa Recipes to Spice Up Appetizers, Main Dishes, & Dips Karla Conrad Types of Tomatillos Most (but not all) tomatillos bear green fruit.
