The Ultimate Guide to Growing Tomatillos in Pots


Tomatillos are a popular ingredient in Mexican cuisines. They’re closely related to tomatoes. But they have a different flavor. Because of the tartness of their husks. Tomatillos can thrive both in gardens and in pots.

Growing tomatillos in pots has many benefits. For example, superior control over soil conditions, improved drainage and the ability to move containers around easily. You can enjoy these flavorful fruits by growing tomatillos in containers even if you don't have much outdoor space.

Tomatillo Varieties for Container Gardening

Characteristics of Tomatillo Plants: Tomatillos are generally considered to be indeterminate and bush-type plants. This means they have an extended growth period and may reach up to 4 feet in height.

When growing tomatillos in pots, look for determinate or semi-determinate varieties. They are smaller and more compact than their indeterminate counterparts. Choose tomatillo varieties with good disease resistance. So they can better withstand their confined environment.

Popular Tomatillo Varieties: The varieties of tomatillos suitable for container gardening include Granadero, Purple de Milpa, Verde Rio Grande and Green Husk. Each of these varieties produce small to medium-sized fruits. They have good disease resistance, and require minimal pruning.

Granadero is a semi-determinate variety. It produces large fruits with sweet green flesh and a firm texture. Purple de Milpa is an indeterminate variety with purple husks and mild tasting yellowish green flesh. Verde Rio Grande is an early mature determinate variety with pale green fruit bodies. Lastly, Green Husk is a tall bush type tomatillo variety with thin skinned bright green fruits.

Consider Some Factors: You should consider several factors when selecting the best tomatillo variety for your container garden. For example, the size of the fruit, taste preference, vigor of the plant, space availability in the pot, and disease resistance. If you have limited space, choose smaller and more compact varieties. For example, Verde Rio Grande or Purple de Milpa.

Granadero may be the best choice if you are looking for larger, sweeter fruits. If you prefer a milder tasting fruit, then Green Husk may be a better option. Because it has thinner skinned green fruits with sweet flesh.

Choosing the Perfect Containers and Potting Mix

Best Tomatillo Container Size: You should choose the ideal pot size for tomatillos. The tomatillo pot size should be 8-10 inches deep. Because tomatillo roots can grow quite long.

Generally speaking, a 5 gallon plant pot is suitable for growing tomatillo plants. However, the distance between the soil surface and the lip of your pot isn't too great. Otherwise, you may run into issues with watering.

Selecting the Right Pots Material: When planting tomatillos in pots, terracotta or ceramic are both good choices. Terracotta helps keep temperatures cool. This is beneficial during a hot summer day. Ceramic will last longer. So if you plan on reusing your pot each season, this might be better.

Good Drainage: Whichever material you choose, make sure your pot has good drainage. To ensure this, drill small holes on the lower sides of your pot. Add a layer of rocks or pebbles beneath the soil to aid with draining excess water. This will keep your tomatillos from sitting in too much moisture. It can cause root rot.

Proper Potting Mix: Soil-less mixes are generally recommended since they provide more aeration and drainage than regular garden soil. A typical mixture for tomatillos is two parts expanded perlite to one part composted manure. You can add some tomatillo fertilizer if needed. The soil pH between 6.5 and 7.0.
