The Best Soil for Growing Tomatoes Upside Down

Tomato plants grow well in an upside-down planter.

An upside-down planter is a good growing environment for tomatoes. The plant receives air circulation, which reduces the risk fungal disease and insect problems. This type of planter works well for homes with patio gardens.

Soil

Fill an upside down tomato planter with a well-draining potting soil designed for vegetables. Look for a potting soil that includes compost or peat moss for nutrients. High quality potting soil is available at garden supply stores. Purchase potting soil rated for vegetable growth.

Amendments

Adding a slow-releasing tomato fertilizer to the potting soil will provide nutrients to the plants during the growing season. A balanced or 5-6-5 tomato fertilizer works well. Mix the fertilizer into the soil before adding soil to the planter. Follow the package instructions based on the amount of soil needed for the planter.

Planting

Feed the roots and stem of the tomato through the bottom of the planter. Hold the stem inside the planter while packing in high-quality potting soil to hold the tomato plant in place. Add several herb or small flower plants to the top of an open upside-down container to prevent soil loss during heavy rains. Basil, parsley, marigolds and sweet alyssum all work well for this purpose.
