Feeding the tomato obsession
THE GARDEN FANATIC
What’s the biggest plant rave every year, from April until the fall?
If you’re Barbara Diamond, it’s the ubiquitous tomato. With names
like Early Girl, Super 100 and La Roma, tomatoes give amateur growers
an opportunity to outdo the farmers. And we do!
A culinary delight for centuries in the Americas, 2003 is only the
168th anniversary of the tomato being recognized an useful vegetable.
The botanical name for the tomato is Lycopersicum, Greek for Wolf
peach, perhaps an allusion to it once being considered poisonous. The
first tomatoes cultivated in the old world were golden, and these
tomatoes became the apples of god from Italy.
Most gardeners start tomatoes with transplants, which are
available at your local nursery. Best Laguna varieties include Early
Girl and Celebrity. If you are growing in containers, select one
named Patio. If you want large tomatoes, Super Steak and Better Boy
are good choices, and Super 100 is a fine cherry tomato. Lemon Boy
produces yellow fruit and La Roma is planted for tomato paste.
Purchase plants that are bushy, not leggy. Resist the temptation
to bring home plants already in bloom or bearing fruit, as they may
not transplant well. Set tomatoes deep, as roots will develop where
the soil touches the stem -- this makes for a bushier, stronger
plant. Finally, choose a location that receives at least six hours of
sunlight, and pinch off extra leaves, reserving a minimum of three
pair at the top.
To prepare the soil, begin by using plenty of composted material
to ensure good drainage and add 15 to 20 pounds of 5-2-1 Gro-power
and 10 pounds of Gypsite per 100 square feet. This initial fertilizer
application will be sufficient for the plant until it sets fruit, and
then it is time to fertilizer again. Feed once a month while the
fruit develops and then discontinue once they near maturity.
Tomatoes require regular watering after the fruit has set, about
two inches a week. One can stimulate earlier fruit production by
placing the plant under a little water stress early, however, be
careful not to over do it. As harvest time approaches, cut back on
watering, to get less watery fruit and increase flavor.
Left to it’s own design, a tomato would prefer to sprawl, and
there is no doubt the yield is heavier when so grown. If you decide
to adopt this method, the indeterminate plants (vine type) must be
set at least 4 feet apart. Determinate (bush type) plants should be
spaced 2 feet apart. Most home growers prefer to save space by
staking their tomatoes, indeterminate plants spaced 2.5 feet apart
and determinate plants 1.5 feet apart. Another option is to plant
tomatoes in cages, allowing them to sprawl upright over the
structure. Count on a yield of 20-40 tomatoes per plant, depending on
conditions and care.
Most of the diseases and problems with tomatoes are in the past,
thanks to the introduction of disease resistant tomatoes. Hornworms
may be removed by hand picking, and eliminated by Bacillus
thuringiensis. Aphids are easily controlled using an insecticidal
soap.
Not maintaining uniform soil moisture after fruit has set, and/or
a deficiency in phosphorous can bring on sunken black areas at the
flower end of the fruit. This problem is called blossom-end rot and
cannot be controlled with a pesticide. Similarly, a white scald on
the cheek of the fruit indicates sunburn and is prevented through
good cultural practices.
Although I hold a true affection for the tomato, I must admit that
the gardeners’ romance with this herb has created some inconvenience.
My hair remains uncut, as Jim is away from his salon, legend says,
preparing tomato paste. Even my colleagues have caught the rage,
missing hearings to cultivate their plants. Fortunately, I count my
blessings that Catharine prefers to write (quite well, I might say).
See you next time.
