Growing Requirements for Tomatillos

Tomatillos, also known as Mexican husk tomatoes, have similar growing requirements to tomatoes. In order to ensure a successful crop of tomatillos, it is important to provide the right conditions for them to thrive.

1. Sunlight: Tomatillos require full sun to grow and produce a good yield. They should be planted in an area that receives at least 6-8 hours of direct sunlight per day. If you have a choice, select a location with southern exposure to maximize the amount of sunlight the plants receive.

2. Soil: Tomatillos prefer well-draining soil that is rich in organic matter. Before planting, it is beneficial to amend the soil with compost or well-rotted manure to improve its fertility and drainage. The pH level of the soil should be slightly acidic, ideally around 6.0-7.0. Conduct a soil test to determine the pH level and make any necessary adjustments.

3. Watering: Tomatillos have a high water requirement and thrive in consistently moist soil. They should be watered deeply and regularly, ensuring that the soil remains evenly moist throughout the growing season. However, be careful not to overwater as excessive moisture can lead to root rot and other diseases. Mulching around the plants can help retain moisture and reduce weed growth.

4. Mulching: Applying a layer of mulch around tomatillo plants can be beneficial in several ways. Mulch helps to suppress weed growth, which can compete with the tomatillo plants for nutrients and water. It also helps to retain moisture in the soil, reducing the need for frequent watering. Organic mulch such as straw, wood chips, or shredded leaves can be used.

5. Support: Tomatillos are vigorous growers and can become quite tall and bushy. Therefore, it is important to provide support for the plants to prevent them from sprawling on the ground and to keep the fruits off the soil. Staking or using cages is a common method of supporting tomatillo plants. The support should be installed at the time of planting or shortly after to avoid damaging the roots later on.

6. Fertilizer: Tomatillos benefit from regular fertilization to ensure healthy growth and abundant fruit production. Before planting, incorporate a balanced slow-release fertilizer into the soil. Additionally, side-dress the plants with compost or a balanced fertilizer every few weeks during the growing season. Be sure to follow the instructions on the fertilizer packaging for proper application rates.

7. Pruning: While not necessary, pruning tomatillo plants can help promote better air circulation and reduce the risk of disease. Remove any damaged or diseased branches, as well as any suckers that may be growing at the base of the plant. Pruning can also help to improve fruit quality and make harvesting easier.

8. Pests and Diseases: Tomatillos are generally resistant to many common tomato pests and diseases. However, they can still be susceptible to certain issues such as aphids, tomato hornworms, and fungal diseases like early blight and powdery mildew. Monitor the plants regularly and take appropriate measures if any pests or diseases are observed.

In conclusion, tomatillos require full sun, regular watering, well-draining soil, and support for their tall and bushy growth. Adding organic matter to the soil, mulching, and regular fertilization can further enhance their growth and productivity. By providing the right growing conditions, you can enjoy a bountiful harvest of these tangy and versatile fruits.
