Container Vegetable Gardening for Kids
Container vegetable gardening is a great way to get kids interested in gardening, and in the modern world, sometimes is the only way to get kids involved. A large percentage of families have no yard at all and containers are the only option. Another advantage is their mobility. Bringing pots inside for winter gardening extends the gardening year.
‘Containers’ covers a wide range of materials, from immovable raised beds to egg cartons. I have had my grandchildren present me with seeds germinated on cotton balls delivered in a plastic bag. usually, containers are pots in 1, 5 or 15 gallons in size. Smaller plants like herbs and flowers will do well in smaller pots while vegetables like tomatoes require the largest size.
The preferred pot is a non-glazed clay pot. The are classic in design and durable (if they are not dropped, that is). Their weight makes them more stable than lighter plastic pots. The porous design helps keep the pot from over-heating in the sun which can be a problem with black plastic pots.
Most pot are sold with a tray or basin meant to hold water leaking through the pots. These are a real problem as standing water promotes fungal diseases. If you must use a tray to collect water from the plants, at least elevate the pots so they don’t stand in water.
Potting media should be a soil-less mix as these are lighter and have better drainage than soil containing mixes. Since the pots only need to last one season, soil-less mixes will do well. Most now have timed-release fertilizer incorporated into their make up. Miracle-Gro and others produce usable media with time-release fertilizer already in them.
If you prefer to make your own mix, the usual mix consist of a blend of peat moss, perlite or vermiculite, compost and sand. The compost is organic material reduced to its most basic components and provides the fertilizer plants need. Even with compost, watering will leach nutrients from the soil and occasional fertilizers may be required. See this article on how to make compost.
Plants for container gardening
Consider the overall area your fully grown plants will take up. If you have room, a full sized tomato in a 15 gallon pot will produce a huge amount of fruit, but smaller varieties are often a better choice.
Tomato Gardening
Tomatoes are the most grown vegetable in the country and deserve special considerations. Cherry tomatoes are suitable for smaller areas and produce a large crop in a short period of time. Standard sizes can become huge and will need to be staked an/or caged.
Most cherry tomatoes are ‘determinate’ types, meaning their crop size is pre-determined by their genetics. They produce their fruit and are over.The clustered tomatoes ‘on the vine’ found in markets are determinate types, and all the fruit develops at once.
Indeterminate types, on the other hand, will produce fruit as long as they are fed, watered and the temperature range stays above 55 degrees at night. See this page orĀ more information on recommended vegetable varieties.
