There are many advantages to growing vegetables in pots. Perfect soil conditions can be created and attacks by pests and disease are usually reduced. A smaller growing area is the biggest drawback, but this can be offset by making use of vertical growing space. Combining a large pot and piece of lattice trellis is a good way to start.Using a pot of sufficient size is the main concern for growing vegetables in containers. Most herbs and greens grow well with in a container 8 inches deep, but for larger plants like tomatoes Solanum lycopersicum, squash Curcurbita spp. and cucumbers Cucumis sativus, 3 to 5 gallons of soil volume per plant is needed to produce a good quality harvest. A 20- to 25-gallon container is ideal for grouping a mix of several different species together while retaining space for a lattice trellis. Use a lightweight soil-less potting mix to make the most of the restricted growing space.
