Planting Tomatoes
How to grow Tomatoes Starting from Planters
You can sow tomato seeds directly in the soil, But it is
preferable to start them off early in sterile planters.
If you are starting your plants from seeds yourself there
are a few tips you may wish to adhere to.
- Check the dates on the seed package, if more than three years old, don't
waste your time. As tomato seeds age, their germination rate decreases.
- For the best chances of success, when starting from seed, either
indoors or directly in the outdoor soil. Acquire your seeds from
a reputable commercial source.
- For seed conditioning prior to planting , one
technique is to soak the seeds in warm water at approximately 50 degrees
C, for slightly less than 1/2 hour. Any hotter, or much longer could cook
the seed .

The best temperature for seed germination is between 70 and 75 degrees
Fahrenheit. Germination at lower temperatures is much slower. If you are using
seed boxes you should cover cover them with glass or plexi-glass and newspaper
during the germination period and turn the glass daily to remove excess
condensation. Very little watering between the sowing of the seed and the
emergence of seedlings is required if done properly. {Plants raised in
boxes although "adequate" have proven to be inferior to those raised in pots or
soil blocks.}Be sure to give the seedlings room to expand. Close
conditions will inhibit their growth. Transplant them to a larger pot as soon as they get several
true leaves [See
Figure 1] , and if need be, move them into larger pots about two
weeks after that.

How to grow Tomatoes -
Conditioning and Hardening your tomato seedlings before transplanting
outdoors is advisable.
- Tomato plants need to be flexible, they must sway freely in the breeze.
Condition your seedlings by providing a breeze by turning a fan on them for
10 - 15 minutes twice daily.
- Harden your tomato plants for several days before transplanting outside.
The first day take the plants outside to a shady, protected spot for a few
hours. Gradually increase the time each day and expose the plants to more
sun and wind .
- Generally, planting outdoors early produces earlier and
better yields . However, if conditions such as temperature, light, or
soil-moisture becomes unfavorable, early planting will increase the risk of
plants aborting early flowers or being destroyed in a late frost.
If purchasing
seedlings for transplant choose those with
straight stalks, at least the thickness of a pen, and with 4 to 6 young
true leaves [See
Figure 1] , but NO blossoms. Plants in individual
peat pots or cell packs experience little or no
transplant shock and become established quickly. Be sure to use a sterile
starting mix , I generally use a half-peat half-vermiculite
mix. I also like to water my tomato transplants with
"Transplant Tonic" immediately after planting. {See
Recipe for Transplant Tonic}
| When
Planting your
seedlings outdoors, Wait till the the last spring frost date in your region
before planting or transplanting outdoors . See
USDA
Zone Map to determine when it is suitable for your area. Optimum temperature for growing tomatoes and for the fruit to set is
range of 70 to 80F (21 to 27C)
Blossom drop can occur in early spring when
daytime temperatures are warm, but night temperatures fall below 55 degrees
F . Blossom drop can also occur in summer months, when days are above 90
degrees F and night temperatures remain above above 75 degrees F, but is
less common in a well maintained and watered garden.
You should plan on at least 2 feet Spacing
between Tomato Plants and another 2 feet
between rows to give you walking room amongst your tomato garden, and to
provide each plant with ample sunshine and air circulation. Plants to be caged are planted
30 to 36 inches apart.
Even if you have
hardened them, it is still advisable that you Transplant tomatoes on a
cloudy, wind free day or wait until the later in the afternoon. Do not
transplant them outdoors in direct summer sunlight.

How to grow Tomatoes
Watering
Watering is critical to the
development of Tomatoes. Water slowly and deeply . Tomatoes
require about an inch of water weekly slightly more in sandy
soils. Inexpensive
water timers are available .
Once the fruit begins to ripen, slightly
decreasing the water will coax the plant to concentrate its
sugars. Don’t decrease the water too much, or that the plants
may wilt and become stressed or they could drop their blossoms
and possibly their fruit.
|
|
At the peak of Summer I prefer to
water every other day, however common sense
observations will of course influence this. Dry hot weather
or heavy wet rainy conditions should influence how often you
supply water. Try not to water from
above , although this is not always feasible. Watering from
above will attract disease and pests to the plants. Watering
tomato plants from above also promotes premature evaporation
. Try not to splash dirt onto the plants as many plant
diseases are from soil borne pathogens. This of course is
minimized assuming your plants are properly pruned.
Mulch helps to keep water where
it's needed and slows down the evaporation process.
Drip irrigation with an
automatic timer provides regular and consistent watering.
Drip Irrigation also allows water to penetrate deeper into
the soil, increasing uptake by plant roots. Inexpensive
Drip Irrigation systems are available

Pruning / "Pinching Back"
Pinch and remove suckers that develop in
the crotch joint of two branches. They won’t bear fruit and will
take energy away from the rest of the plant. But go easy on
pruning the rest of the plant. You can thin leaves to allow the
sun to reach the ripening fruit, but it’s the leaves that are
photosynthesizing and creating the sugars that give flavor to
your tomatoes. Excessive pruning can also lead to
Sunscald

|
Once the tomato plants are about 3'
tall, remove the leaves from the bottom 1' of stem. These are usually the
first leaves to develop fungus problems. They get the least amount of
sun and soil born pathogens are frequently splashed onto them.

How to grow Tomatoes -
Fertilizing
Tomatoes thrive in rich soil, compost, lots of water, lots of sun ..6 or
more hours daily, They are acid loving plants and like composted manures
. Optimal soil pH for tomato plants is 6.0 to 6.8 see
Soil Ph for more
extensive data.
Tomatoes respond well to fertilizer , especially phosphorus. Excess
nitrogen fertilizer can result in plants with excessive vine growth but
little fruit production. |
|
Apply 2-1/2 to 3 pounds of a complete
fertilizer, such as 5-10-10, 5-20-20, or 8-16-16 per 100 square feet of
garden area. Work the fertilizer into the soil about 2 weeks before
planting.
I use
Fish Emulsion
twice a season shortly after the first
blossoms appear, and again when the plants
are laden with fruit. Make sure to
dilute liquid fertilizer as most are heavily
concentrated and will burn your plants if
applied too heavily. I also use
Miracle-Gro Tomato Food
, in extremely diluted from every other week
- dilute slightly more than twice the
package recommendation assuming you will
also be using Fish Oil as well as standard
fertilizers. Miracle Gro formulated
for tomatoes
contains many nutrients not found in other
fertilizers , and sometimes lacking in
nature, it also Starts working instantly.

Crop Rotation and Companion
planting
Tomato plants
should be on a Three - Four-year rotation with non-related crops and
using plants grown from disease-free seeds. This will help control most tomato
diseases. Avoid Eggplants, potatoes, peppers, okra, raspberries, or
strawberries in rotation with tomatoes.

Tomatoes and cabbage or cauliflower (The Brassica
Family) go fine together in a salad but are not compatible in a garden
setting if you are planting "Brassica" crops, keep them well separated from
the tomatoes. Try planting Basil, Chives, Lettuce (Not Brassica family) in
between the Tomatoes ...also lots of Marigolds.
Good Companions of
Tomato plants are asparagus, basil, bush bean, carrot, celery, chive,
cucumber, garlic, lettuce, onion {

microscopic worms which
live in the soil and feed on the host plants roots preventing the the plants
from taking up the nutrients they need to grow . Some forms of nematodes are
highly beneficial , while others can wreak total destruction . Tomato plant
nematodes are prevalent throughout North America, but they are most damaging
to tomato plants in the Southern regions of the US.
Hot Pepper Wax
repels bugs from your plants, fruits and flowers. 100% natural spray
uses pepper extract and wax to effectively discourage pests. Helps to reduce
stress on cuttings.
Sharpshooter Natural Insecticide
Citric acid destroys the wax coating of the insect's respiratory system.
When applied directly, the insect suffocates. Sharpshooter is biodegradable.
Persons with known citrus allergies may be affected. Do not spray on red
mature fruits. Effective on most insects including aphids, beetles,
caterpillars, cutworms, earwigs, flies, gnats, lacebugs, leafhoppers,
