Topsoil for Container Tomatoes

Pots

• Container tomatoes require adequate space for both roots and foliage, with weight for balance. Use 5-gallon pots with drainage holes for individual plantings and larger containers for multiple plantings. The Ohio State University Extension recommends 12-inch-wide plastic pots for tomato growing and notes the importance of drainage holes in all pots.

Potting Soil

• Tomatoes need moisture and rich nutrition in their soil, and won't grow to full potential in topsoil alone. Mix topsoil with an equal amount of organic compost for richer, darker soil. The Ohio State University Extension also recommends peat moss and perlite for container plants. The University of Missouri Extension recommends starting tomatoes with 6-24-24 or 8-32-16 starter fertilizer for best rooting.

Container Cultivars

• Tomatoes grow in determinate and indeterminate varieties and standard to dwarf, cherry or container cultivars. Plant small cultivars or small determinate (limited-growing) varieties in pots for smaller, contained growth. Good container choices include Tiny Tim, Roma, Cherry Gold, Sweet Million, Red Robin, Pixie Hybrid II and Small Fry.

Care

• Keep container tomatoes in indoor or outdoor locations with full sun or artificial light every day. Water the plants with 2 inches of water anytime they dry and at least every four to five days. Place a stake in each pot for growing support during the season. The Ohio State University Extension suggests feeding container tomatoes with water-soluble 20-20-20 or 15-30-15 plant food. Feed the plants once a week starting at mid-season for better blooming and fruiting. Expose indoor plants to good air circulation for pollination at blooming.
