Climbing vegetables (such as pole beans and peas) benefit from support, as do some sprawling sorts, including cucumbers, melons, and tomatoes. Put up the supports at planting time; roots won't have spread yet, so you needn't worry about disturbing them. Train or tie the plants as they grow.
1. Broad-mesh plastic netting attached to hooks in metal fencing stakes can support cucumbers, squash, beans, and peas.
2. Cylinder of welded wire and two stakes support a tomato plant with a minimum of tying. Reach through mesh to harvest.
3. Tepee of bamboo poles tied together at top supports beans planted beside poles.
