Planting [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
in containers can be an effective way to combat garden pests and diseases while 
providing easy access to your crop.

When planting, be sure to bury the stem and apply mulch (straw, weed-free shredded
bark or compost) as an aid for soil moisture conservation. Water slowly and deeply
to allow all the moisture in the soil to percolate completely through it.

## Choose the Right Pots and Soil

[Tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants require plenty of light and warm soil in order to thrive, and are best suited
to 4- to 6-quart containers, although larger pots or hanging baskets may work as
well. When choosing your container, look for one wide enough to allow the [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plant to spread out and develop a strong base without waterlogging the soil; [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants also require good drainage in order to avoid waterlogging the soil and disease
organisms which could threaten its viability – consider opting for premium quality
potting mix or aged compost-enriched soil instead of garden soil reusing garden 
soil that may contain harmful disease organisms which could harm them rather than
reuse garden soil that may contain disease organisms which could harm them over 
time.

[Tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
require regular feeding as they grow and produce fruit. Since containerized [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
may only receive nutrients contained within their container, it’s crucial that after
planting and each week throughout their growing season you use an organic liquid
feed or time-released organic fertilizer containing balanced nutrition (either liquid
feed or time release), according to its instructions on its label for dilution rates
and timing.

Mulching around the base of your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants is an effective way to help keep soil moisture levels up, yet shouldn’t cover
too deeply so as not to restrict air circulation and promote disease. Refresh it
often during hot weather to ensure optimal conditions.

Trellis or stake support for [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants is necessary as they expand taller and produce fruit, while without them 
they would flop over and become damaged by rain or wind. [Tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
cages work well for determinate varieties available at garden centers while wooden
or plastic stakes with string can help support indeterminate varieties. It is best
to install stakes and trellises as soon as the plants have been planted to avoid
interference with root systems and increase growth potential.

[Tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
are heavy feeders and require additional nutrients in order to produce well and 
continue producing throughout the fall season. A general multi-purpose garden fertilizer
may work when planting, but once fruit-set begins switch to a product with higher
nitrogen, phosphorus (often seen on labels as NPK ratios) and potassium content.

## Choose a Sun-Loving Location

[Tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
are warm-weather plants, so they require ample sunlight in order to flourish and
produce fruit successfully. Without enough sunshine, your [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
may suffer stunted growth, few or no flowers and undersized fruits. At minimum, 
your [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
should receive 6-8 hours of direct sun daily; 8 is optimal. Determine how much direct
sun your patio receives before planting containers there; move containers accordingly
if necessary to find a spot with enough light; morning sunlight is optimal since
it helps evaporate dew and is less harsh than afternoon rays.

Growing [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
in pots requires extra attention when growing in pots due to their increased susceptibility
to environmental elements than those planted directly into the ground, so they require
special consideration and special care in order to remain healthy and productive.

Choose a location where containers will receive ample sunlight and are easily accessible
for pruning and harvesting purposes. [Tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants can become tall and sprawling as they mature, so regularly pruning will prevent
their branches from becoming too heavy and potentially damaging your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plant or knocking off fruits.

To ensure that [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants have enough nutrition throughout their lives, amending the soil with organic
matter before planting is recommended. Doing this can improve overall soil quality
while offering additional advantages when it comes to watering and feeding your 
[tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants.

When adding organic matter, ensure to use high-quality compost or potting soil –
standard garden soil is too compacted for container gardening and may prevent proper
drainage. Also include slow release fertilizers; [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
require regular feedings in order to support strong growth and abundant fruit production.

Mulching is essential when growing [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
in containers, as it helps retain soil moisture. To prevent the top layer of soil
from drying out too quickly, choose mulch made of straw (not hay which may contain
seeds) or organic material like shredded bark or arborist wood chips as a moisture
retainer. Mulch should especially be applied during hotter weather when watering
frequency will likely be increased significantly compared with cooler or milder 
conditions.

## Water Daily

[Tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants are heavy feeders and require constant sources of nutrients in order to produce
large volumes of fruit. [Tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
thrive best in nutrient-rich potting soil that drains well; for optimal results,
amend it with slow-release organic fertilizers like Osmocote before planting.

Watering [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
in containers requires deep soaking of at least an inch, not spraying water overhead
as this wastes precious moisture through evaporation and can splash onto leaves 
which don’t need it.

mulching [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants in warmer regions is a good way to help retain soil moisture, particularly
for better growth and moisture retention. Hay, straw and chopped leaves all work
well as mulch material; other growers also utilize newspaper without glossy circulars
that decomposes quickly while providing added hydration benefits.

Once your [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
have been planted, water them twice per day until their roots take hold. After that,
one watering per day should usually suffice unless temperatures outside are especially
hot or dry.

Make sure that your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants receive plenty of direct sunlight. They need at least six to eight hours 
a day in direct light to maximize growth and yield, although morning sun tends to
be gentler on plants than afternoon sunlight.

If your plants are overcrowded, pruning will help thin out their foliage and promote
new shoots and vines to emerge. If their proximity makes support necessary – especially
with heirloom varieties which need special support to avoid cross pollination that
could have detrimental results – pruning alone won’t do.

Harvest the [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
as soon as they ripen to avoid over-farming your plant, which could otherwise lead
to disease and reduced crop quality. Refrigerating any unneeded [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
would be wise, though any stored for later could lose flavor and turn soft in storage.
Green [tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
must never be stored for later as this could compromise their flavor and become 
soggy in texture.

## Fertilize Regularly

[Tomatoes](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
are heavy feeders and require regular supplies of nutrients in order to thrive, 
so for maximum yields use premium quality potting mix like aged compost-enriched
Miracle-Gro Performance Organics All Purpose Container Mix as your starting point.
The fluffy soil helps air and moisture move freely through your planting container,
which reduces disease and pest risks, according to Gardening Know How. Also add 
Osmocote continuous release fertilizer on top of the container before placing your
[tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plant inside it – its slow release formula supplies the plants with steady supplies
of nitrogen, phosphorus and potassium as well as calcium for blossom end rot prevention!

Avoid using garden soil from planting beds as this may contain disease organisms
and become over-compacted when combined with potting soil. If necessary, lightly
work this gardening soil into the potting soil so as to break up any large clumps
and loosen it before transplanting.

When transplanting [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants, gently untangle their roots for an easier transition into their new environment.
Water well before transplanting. If your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
becomes root bound in its container, repot it into a larger-sized pot so as to maintain
maximum productivity and happiness for all involved.

Your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants need 6-8 hours of direct sunlight each day in order to thrive during summer.
If your current location doesn’t get this amount of sun, consider moving the containers
onto a deck or patio where there’s more direct light.

If you live in an extremely warm or windy location, mulch your plants with straw,
shredded bark, or chopped leaves to help retain moisture and suppress weeds while
cooling the roots – which reduces chances of disease.

If you struggle to remember to water your [tomato](https://lifeandwork.blog/my-published-works/gardening-books/from-seed-to-harvest-tomato-gardening-for-self-sufficient-living/)
plants every day, investing in an “wall of water” irrigation system might be the
perfect way to ensure they get consistent moisture. Or consider getting yourself
an EarthBox, which features an automatic reservoir that eliminates manual watering
requirements.
