Growing tomatoes is a must for home gardeners

There is nothing more symbolic of home gardening than the tomato.  And with good reason:  the closer a tomato is grown to home, the better it tastes!

The varieties of tomatoes you find in the grocery store have been selected for traits that are important for a commercial crop:  the fruit all tend to ripen in a short period of time, they transport well, and are resistant to common diseases.  Taste is well down on their list of important qualities.

To grow your own tomatoes, you can buy plants that have already been started.  It is becoming easier to find more than just two or three varieties of plants than in the past, and you may be lucky enough to find some heirloom tomato plants at your local farmer’s market.  But for the best selection, you should start them yourself from seed.

Tomatoes have a relatively unique ability to grow roots out of their stems.  When transplanting, take advantage of this by planting them deeply.  You can bury the plant up to the embryonic leaves, or even the first set of true leaves.  The buried stem will develop roots, adding to the stability of the plant, and also its ability to scrounge for nutrients.

IMG_4858There are two main types of tomato plants, defined by their growth habits.  Determinate plants are short and bushy, and the fruit tends to ripen all at once.  Indeterminate plants grow tall and vine-like, and will produce fruit over the entire summer.  Determinate plants can use support like the short, round tomato cages that are easy to find in the stores.  Indeterminate plants will outgrow these cages quickly, and are better tied to poles.  Some varieties will grow over 6′ tall!

I usually grow indeterminate plants because I like the staggered maturity, and also there are many more indeterminate than determinate varieties available.

If you haven’t tried growing tomatoes, what are you waiting for?  Fantastic flavour is waiting for you!
