Clever Gardening Technique

Trellises = more, healthier yield
Trellises provide support for greater fruit production per square foot of soil and over longer periods of time. This increase happens because more leaf area is exposed to sunlight for more photosynthesis, and more air circulation means less fruit rot and ground-insect attack. Crops grown on a trellis are easier to pick and are cleaner, not available to snails and slugs, and not prone to ground rot.

Some vines need more guidance and anchoring onto the trellis than others. Clamp clothes pins attached to twine on each side of a vine for easy adjustment as the vine grows. Support heavy fruits on shelving, in netting, or with rags or old nylons. If left unsupported, their weight will drag the vines down from the trellis. When weeds are pulled up from beneath trellised vines, there is less injury to the cultivated plants because of vines and fruits up out of the way.

Vines spreading on a trellis can also provide shade for a porch, patio or wall.
