The satisfaction of raising a bountiful crop of delicious, fully ripe tomatoes can't be beat, and as experienced gardeners will tell you, so much depends upon the weather. Most people will start their seeds indoors where they can control the soil, water, light, and temperature. Once the seedlings move outdoors, it's less an exact science and more what works in the environment provided.

One rule of thumb is to plant the seedlings deep, leaving only two sets of leaves above ground, even if it means stripping off bottom leaves on a particularly leggy start, or actually laying it at an angle with just two sets of leaves above ground. All the little hairs along the stem will become roots, providing that much more water and nourishment to the plant. You'll also want to install your support, be it a cage, trellis, or some other structure, at the time of transplanting so the roots aren't damaged later on. Planting a tomato with no or too small a support will only cause heartache, even with a determinate plant like Ace 55. Its non-vining growth habit also makes it a good candidate for container gardening.
