Trellises in the Vegetable Garden

Many vegetable garden plants thrive when trained to a trellis. Not only does trellising make more room in your garden, it also maximizes air circulation and keeps plants off the soil, both of which can help prevent diseases. Soil-dwelling pests, such as slugs, will have a harder time reaching your crop. Plus, trellising also makes harvesting easier.
Plants to trellis include cucumbers, beans, summer squash, and tomatoes. If you plan to trellis, look for varieties labeled as vining or pole, rather than bush. For tomatoes, look for indeterminate, as opposed to determinate, varieties. Beans, cucumbers, and squash will climb on their own (though you may need to guide the vines to get them started) but tomatoes must be tied to the support. Melons can be trained to a trellis, but you'll have to support developing fruit, so its weight doesn't tear the vine or cause the whole setup to topple.
