A reader from Oyster Bay Cove asks, "What is the correct size pot for growing little cherry tomatoes? "
You're wise to ask that question, as many people make assumptions that end up costing them dearly. Using a pot that's too small could result in a root-bound and unhealthy plant. Likewise, a too-large container could hold too much water and lead to root rot. Neither scenario will yield many tomatoes.
My personal preference for growing tomatoes in containers these days is the EarthBox (photo above.) I saw them at Hicks Nurseries in Westbury recently, but they're pretty widely available in local garden centers and online. You can buy the optional trellis system for your tomatoes to climb on and you'll probably get a much larger harvest than if you planted them in the ground. You'll never need to worry about weeding, over- or under-watering or feeding. On the downside, the box is pricey, and you can only put two plants in each box.
If you'd prefer a standard container, get one that holds at least five gallons of soil (a 5-gallon paint bucket would work nicely) and don't forget to poke or drill holes in the bottom for drainage and provide something for the plants to climb on. Fill the container with good-quality potting soil and place only one plant in each pot.
Tomato plants require calcium, and some people swear by placing a whole egg in the soil under the plant. Others crush up egg shells and mix them in with the soil. The plants will benefit similarly by an occasional watering with water in which youve boiled eggs. Any of these methods will help prevent blossom end rot.
Be sure to check moisture levels diligently, as potted plants require more frequent watering than their garden-planted counterparts, and fertilize with a balanced fertilizer (one with equal parts nitrogen, phosphorus and potassium) when the plants are a month old and then regularly after theyve set fruit. To avoid over-feeding, fertilize at half the strength recommended on the package instructions, and do it twice as often. Over fertilizing could result in big, beautiful foliage but an unimpressive crop.
Place your pots in a bright, sunny spot and in no time you'll be enjoying the fruits of your labor.
