Soil Preparation:
Compost (Nitrogen), 2", in top 10" of soil, 1 time: It is important to add organic matter to the soil, as well as to supply nutrients to the plants.
Start Indoors
Soil temp for germination: 60°F to 75°F, optimal 65°F to 70°F, optimal 69°F
Total weeks to grow transplant: 12 to 15 (Spring/Summer), (Fall/Winter)
Harden Off: 1 weeks after last frost date. Before transplanting outside you must harden off the seedlings, so they become accustomed to somewhat less than ideal conditions.

Support: Yes. Use a tomato cage to support these tall bushes, which can get 3-4' tall!
Water Needs: Moderate. Tomatillos are quite drought tolerant, but for best fruit production they should be watered regularly.
Fertilizer Needs: Light. Generally, Tomatillos are independent plants and don't need a lot of attention. Give them a feed of compost tea or liquid Kelp when the flowers first appear.
Protecting, while danger of early frost: Row covers, 1 layers, while danger of early frost, 1 time. Put a cover over plants while danger of frost is present This is important, as an early frost in fall will usually kill unprotected tomato plants. If you can help your plants make it through these first frosts there may not be another one for several weeks, during which time you can get a lot more ripe fruit. Almost anything can help them to survive a mild frost, old bed sheets, straw mulch, plastic sheet, cardboard.
Side Dressing, at flowering: Mulch, 2 inches, at flowering, 1 time. A 2" mulch of straw is useful to keep down weeds, conserve moisture and keep the fruit clean. It can also reduce disease problems by keeping soil off of the foliage. Don’t put down an organic mulch until the soil is warm (when plants start to flower), as it could insulate the soil and keep it cool.
Side Dressing, at early fruit set: Compost tea, 1 cups, at early fruit set, 1 time. Give each plant a cup of diluted compost tea or liquid kelp (use as directed) after the first fruits are set.
Watering, before fruit set: Water, 1 gallons per plant, before fruit set, 2 times a week. Tomatillo is quite drought tolerant but for best fruit production they should be watered regularly.
Watering, during fruit production: Water, 1 gallon(s) per plant, during fruit production, 3 times a week
Support: Yes. Use a tomato cage to support these tall bushes, which can get 3-4' tall!

Culinary Use:
The Tomatillo is important in Mexican cooking, for its use in salsa verde and other dishes. It is not usually eaten out of hand.
Fruit: raw or cooked. The fruit is a berry that is 2.5 cm or more in diameter. When not fully ripe, the fruit can be cooked and used in curries, sauces, soups, stews etc. A delicious flavoring when used like a tomato and added to soups, stews etc. The fully ripe fruit is sweeter and can be eaten out of hand, added to salads or used in pies, preserves etc. The plant conveniently wraps up each fruit in its own "paper bag" (botanically, the calyx) to protect it from pests and the elements. This calyx is toxic and should not be eaten. The fruit can be stored for up to a year if picked before they are fully ripe and left inside their calyx.
Known Hazards: All parts of the plant, except the fruit, are poisonous.

The Health Benefits of Tomatillo
Prevent Cancer: Tomatillos contain unique antioxidant phytochemicals called withanolides , which have been directly linked to anti-cancer and antibacterial functions. Antioxidants help to combat the effects of free radicals, which are the dangerous byproducts of cellular reproduction that can kill or mutate healthy cells and turn them into cancerous cells. Furthermore, the vitamin A, vitamin C, and flavonoids within tomatillos provide other cancer-protective effects, particularly in terms of lung and oral cancers.
Boost Immune System: The vitamin C found in tomatillos can help to boost the immune system by stimulating the production of white blood cells, the body’s primary line of defense against foreign agents and pathogens. Vitamin C is also a key component of collagen production, which supports the health and creation of skin tissue, as well as the cells and tissues that make up our organs and blood vessels, increasing the body’s sustainability and metabolic functions.
Improve Vision: Vitamin A has long been connected to the health of our vision. Tomatillos also contain beta-carotene, a derivative of vitamin A, that functions as an antioxidant and prevents macular degeneration, cataracts, and other conditions that can affect the health of our eyes.
Help in Weight Loss: Tomatillos are one of those preferred vegetables for people who are trying to lose weight. High-nutrient, low-calorie, and low-fat vegetables with high fiber content, like tomatillos, help people to feel full, acquire the necessary nutrients on a daily basis, and reduce the chances of overeating, because they feel satiated. They are ideal if you are trying to reduce obesity for a healthier lifestyle.
Boost Energy Levels: Niacin is a member of the B-family of vitamins that are often overlooked in human health. Niacin is a key element in the enzymatic processes that break down food and complex molecules into usable energy for the body. by increasing the availability of this energy and making the process more efficient, the niacin found in tomatillos can give you a sustainable boost of energy throughout your day.
A Final Word of Caution: Nightshade vegetables tend to have high levels of alkaloids, which can exacerbate inflammation of the joints if you already have certain problems with arthritis or inflammation. However, tomatillos possess relatively low amounts of alkaloids. That being said, consult your doctor before adding tomatillos to your diet if you suffer from these types of health conditions.
