Final Preparations

Every plant must compete with everything else in your garden for water, light, nutrients, and root space.

Knowing how close you can arrange your plants and proper plant support is critical to maximizing your garden's productivity while still achieving robust plants and vegetables.

Vegetable Spacing Recommendations

Different vegetable types need different amounts of free space to ensure healthy growth and a good crop. Use this chart to make sure your vegetable plants have room to grow.

Plants in inverted hill should be thinned after germination to 2-3 plants per hill. Hills should be 36"-72" apart.

Support

Some vegetables such as tomatoes and peppers, and climbing vegetables such as beans, cucumbers and winter squash require support as they mature to help them grow.

STAKES
60x2x2" stakes provide adequate support for most tomatoes and other plants requiring support. Drive the stake into the ground about 24" before transplant so not to disturb the root system of established plants. As the plant grows, use twine, plastic tape or velcro to lossely tie it to the stake. Be careful not to tie it too tight, this could end up damaging the plant as it grows.

CAGES
Cages are readily available at most nurseries. But these can also be made a home fairly easy. Using heavy wire cutters, cut a 5 - 6 foot section of wire fencing leaving prongs along the side. Bend into cylinder and clamp together using prongs. Cut off the bottom rim so the bottom spikes can be pushed into the soil around the plant.

TRELLIS
A trellis is a great idea for climbing vegetables such as beans and winter squash. One trellis can support several different vegetables at a time. Vines will be climbing on the trellis for several months, so you will need into take consideration its sturdiness. 4x4" posts driven deeply into the ground or a tee-pee design that supports itself are typical designs. Lace heavy twine or wire from tower to tower. Then pattern string from top to bottom to support the crop. Your trellis system will need some kind of support.
