Frequently Asked Questions

Why are my tomatillo plants not producing fruit?

If your tomatillo plants are not producing fruit, it could be due to a lack of pollination. Tomatillos are self-incompatible, meaning they need to be cross-pollinated by another tomatillo plant to produce fruit. Make sure you have multiple plants nearby to ensure proper pollination. Additionally, ensure your plants are receiving enough sunlight, water, and nutrients.

What's causing the yellowing of my tomatillo leaves?

Yellowing leaves on your tomatillo plant can be caused by overwatering, underwatering, or nutrient deficiencies. Check your soil moisture by sticking your finger into the soil up to the first knuckle. If the soil feels dry, it's time to water. If it's already moist, wait a day or two before watering again. Also, consider getting a soil test to determine if your soil lacks essential nutrients like nitrogen, iron, or magnesium.

How often should I water my tomatillo plants?

Tomatillo plants need consistent moisture, especially when they're producing fruit. Water your plants when the top 2-3 inches of soil feel dry to the touch. Avoid getting water on the leaves to prevent fungal diseases. Instead, water at the base of the plant, allowing the soil to absorb the water.

Why are my tomatillo plants so leggy?

Leggy tomatillo plants can be caused by insufficient light, inadequate pruning, or excessive nitrogen fertilization. Tomatillos need at least 6 hours of direct sunlight per day. Prune your plants regularly to encourage bushy growth and promote fruiting. Also, avoid over-fertilizing with nitrogen-rich fertilizers, as this can promote leaf growth at the expense of fruit production.

Can I grow tomatillos in containers?

Absolutely! Tomatillos can thrive in containers as long as they receive sufficient sunlight, water, and nutrients. Choose a container that's at least 12-18 inches deep and has good drainage holes. Use a well-draining potting mix and fertilize regularly. Keep in mind that container-grown tomatillos may require more frequent watering and fertilization.

How do I support my tomatillo plants?

Tomatillo plants can grow quite large and produce heavy fruit, so they need support to prevent them from toppling over. You can use tomato cages, trellises, or stakes to provide support. Install the support system early, when the plants are still young, to prevent damage to the stems.

What's the ideal temperature for growing tomatillos?

Tomatillos prefer warm temperatures between 65°F (18°C) and 85°F (29°C). They're sensitive to frost, so wait until the last frost date in your area has passed before planting. Avoid exposing your plants to extreme temperatures, as this can affect fruit production and plant health.

Can I grow tomatillos from seed?

Yes, you can grow tomatillos from seed. Sow seeds indoors 6-8 weeks before the last frost date in your area. Transplant seedlings outdoors when they have 2-3 sets of leaves. Keep in mind that tomatillos grown from seed may not produce fruit that's true to the parent plant's variety.

Why are my tomatillo fruits not turning yellow?

Tomatillo fruits typically turn yellow or purple when they're ripe. If your fruits are not turning yellow, it could be due to a lack of calcium, which is essential for fruit ripening. Ensure your soil has adequate calcium levels, and consider adding calcium-rich fertilizers like bone meal or crushed eggshells.

How do I store tomatillos?

Tomatillos can be stored at room temperature for up to 1 week. Remove the husks and wash the fruits gently. Store them in a paper bag or wrap them in a paper towel to maintain humidity. You can also store tomatillos in the refrigerator for up to 2 weeks or freeze them for up to 6 months.

Can I grow tomatillos in shade?

While tomatillos can tolerate partial shade, they prefer full sun to produce well. If you must grow them in shade, ensure they receive at least 4 hours of direct sunlight per day. Keep in mind that shaded tomatillos may produce fewer fruits and be more prone to disease.

Why are my tomatillo plants flowering but not producing fruit?

If your tomatillo plants are flowering but not producing fruit, it could be due to a lack of pollination or inadequate fertilization. Ensure you have multiple plants nearby to promote cross-pollination. Also, consider adding a balanced fertilizer that's rich in phosphorus to promote fruiting.

Can I eat tomatillo leaves?

While tomatillo leaves are technically edible, they're not typically consumed due to their bitter taste and potential toxicity. Tomatillo leaves contain a compound called solanine, which can be toxic in large quantities. Stick to eating the fruits, which are delicious and safe to consume.

How do I prevent pests from attacking my tomatillo plants?

Common pests that attack tomatillo plants include hornworms, aphids, and whiteflies. Use organic pest control methods like neem oil, insecticidal soap, or hand-picking to control infestations. Keep your plants healthy and well-watered to prevent pest issues.

Why are my tomatillo fruits cracking?

Tomatillo fruits can crack due to sudden changes in water availability, causing the skin to split. Ensure consistent moisture levels, and avoid sudden droughts or overwatering. Also, consider providing support to the plants to prevent heavy fruits from breaking the stems.

Can I grow tomatillos in the same bed as other vegetables?

Tomatillos can be grown alongside other vegetables, but they do have some specific requirements. Avoid planting them near members of the Brassica family (broccoli, cauliflower, etc.), as they can be susceptible to the same diseases. Tomatillos also prefer well-draining soil, so avoid planting them in areas with heavy clay or waterlogging.

Why are my tomatillo plants not growing?

If your tomatillo plants are not growing, it could be due to inadequate light, water, or nutrients. Ensure your plants receive sufficient sunlight, water, and fertilization. Also, check for signs of pests, diseases, or nutrient deficiencies, which can hinder plant growth.

How do I propagate tomatillo plants?

Tomatillo plants can be propagated through cuttings, layering, or division. Take 4-6 inch cuttings from the tips of the stems, remove lower leaves, and plant them in a pot filled with a well-draining mix. Keep the soil moist and warm until roots develop. You can also layer stems by bending them down to the ground and securing them with a rock or U-pin.

Can I grow tomatillos in acidic soil?

Tomatillos prefer slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. If your soil is highly acidic, consider adding lime to raise the pH. However, be cautious not to over-lime, as this can lead to nutrient deficiencies.

Why are my tomatillo fruits not sweet?

Tomatillo fruits may not be sweet due to inadequate ripeness, poor soil quality, or insufficient water. Ensure your fruits are fully ripe, as they will continue to sweeten after harvesting. Also, check your soil quality and adjust your fertilization and watering schedules accordingly.

Can I use tomatillos in cooking?

Absolutely! Tomatillos are a delicious and versatile ingredient in many Mexican and Latin American dishes. Use them in salsas, sauces, soups, salads, and as a topping for tacos and grilled meats. They can be roasted, grilled, or sautéed to bring out their unique flavor and texture.

Why are my tomatillo plants dropping their flowers?

Tomatillo plants may drop their flowers due to inadequate pollination, excessive nitrogen fertilization, or sudden changes in temperature or humidity. Ensure proper pollination, adjust your fertilization schedule, and provide a stable environment to promote fruit set.
