Growing
Tomatoes as Houseplants

Plants in the house help improve the quality of the air, provide interesting
conversation pieces, and add to the decor. Houseplants don't have to be the
traditional English ivy, or philodendron. Many of us have grown herbs in the
kitchen window, so growing a tomato shouldn't cause you worry. Tomatoes are
simple to grow for even the novice indoor gardener. The reward of actually
picking a ruby red tomato from your plant is one that most indoor gardeners
miss.
Deciding what variety of the myriad available is probably the hardest
part. In the spring your garden center will have tomato seedlings for you to
choose from. You can also choose to grow your plant from seed, or a cutting
from a tomato plant that is established. The only rule is you want to choose
a tomato that is an indeterminate grower (meaning it doesn't stop producing
fruit and flowers).
After you have chosen your tomato, you will
want to put it in a pot. The pot size will determine the size of the
finished tomato to a certain extent. If you want a small plant that will sit
on a windowsill, then choose a pot that will fit nicely with a drip tray on
the windowsill, or perhaps you want a tall bush that will sit on the floor
next to your favorite chair. The pot should have drain holes, but if the pot
of our choice doesn't then you can insert one that has a drain hole in the
decorative pot.
When watering your plant, use a weak
solution of plant fertilizer. Tomatoes are heavy feeders so you will not
over fertilize if you mix the plant food about 1/4th the usual strength.
Unless you are starting your tomato from
seed, you will want to dig a shallow trench across the pot, ending the
trench in the center. Place the roots near the edge of the pot, and then lay
the tomato down in the trench. Any leaves that are lying in the trench
should be clipped off. Now bury the roots and part of the stem, gently
pressing the soil against the roots and stem. Your plant will be lying down,
but over the next few weeks it should angle up, if not then encourage it to
grow upwards with a small stake. Water with tap water or weak plant food
solution for transplants.
Your tomato will do best in a very sunny
location, preferably a south-facing window, but if a southern window is not
available, you can supplement the light with grow lights, or daily trips to
a sheltered location. Water your tomato when the soil is dry on the surface.
Don't worry about over watering, since tomatoes don't mind roots that are
slightly moist. Some of the best plants have been grown when I keep them in
a drip tray that is kept full of water.
You should notice new growth in about a
week. If your tomato starts to get leggy or lean to one side then you will
need to turn the pot more often, and provide extra light. Many times a
simple foil reflector placed to reflect more light onto the plant will
encourage more vigorous growth. If this doesn't work after a week or so,
then placing your plant closer to the window or outside for two or three
hours in the sunlight will correct the problem. Tomatoes can easily become
frost bitten. If you need to provide extra sunlight and the outside
temperatures are below freezing, or their is a cold wind blowing try placing
your plant in a car that is parked in the sun for a few hours.
Tomatoes are perennials, so will grow and
produce fruit and flowers year round if you can provide the required amount
of sunlight, and warmth. As your tomato grows it will send out side shoots.
You should allow a few of these to develop into branches, but pinch or clip
off the others. The clipping and pinching will encourage your plant to bush
out and become an appealing healthy plant. You may need to stake the plant
if it becomes tall or top heavy. I have seen some very decorative plant
stakes, including a friend who placed a tomato in a silk fig tree and just
tied the tomato to the silk plant.
When you notice the first signs of blossoms
on your plant, you will know that you have the sunlight and water just
right. Let the flowers open fully, and then spray lightly with a
commercially available blossom set. Tomatoes are "self"
pollinating, so unless you're trying to produce a hybrid, nothing more needs
to be done.The small tomatoes that will form are a reward for a job well
done.
A word of caution here, tomato leaves are
poisonous, so take care if you grow your tomato near small children or pets.
Bring a little of the summer goodness into
your home, and enjoy the fruits of your labor. Tomatoes grown at home have a
flavor more intense than those commercially grown.
