Size of a Tomato Plant Container

A truism right out of "gardener's elementary school": a plant's root system is the same size as its visible growth. That's a lot of roots!

But a tomato plant doesn't mind having 'balled up' roots, so as long as the pot is at least a certain size, you'll be okay.

Avoid Root Rot

However, the one golden rule is to avoid letting the plant stand with its roots forever wet. Your container MUST have adequate drainage for the water to escape through.

Root rot will develop otherwise, and the plant will never do well.

Good drainage should be a given when you buy a container that's designed for the purpose.

However, if you're using a whiskey barrel, old bathtub, some kind of home-made container, or anything else you've scrounged up, then you're going to have to drill some drainage holes.

Space these a few inches apart, and ensure that the lowest point of the tomato container (if the item is not totally flat underneath) gets particular attention.

Choosing a Tomato Container

There are as many solutions for growing tomatoes in as there are tomato varieties! Any of these will be great choices for you.

Akro-Mils Stack-A-Pot Review: What's Good and Bad

Ease of assembly: just stack the pots on top of each other to start on your latest gardening project

Convenient: the pots are collapsible and can be easily stored whenever not needed

Durable: this stacker planter can withstand all four seasons outdoors

UV-protection: this withstands the harsh effects of the sun without releasing harmful vapors from the sun's UV rays

Too heavy to mobilize: a 30-quart worth of soil is too heavy to move around without the help of moving and transfer tools

Over-saturation of the bottom pots: if the top tiers are watered more than required, it is possible to drown the plants on the lower section of the stack, as the water from the top sections naturally find its way to the bottom

It can grow all sorts of flowers and crops even with limited space.

Island Grow Pots 5 Gallon Grow Bag Container: Why We Love It

Planting in bag tomato containers are popular in Europe, particularly for growing potatoes. It is a brilliant alternative to customary planting.

Traditional plastic pots can damage the roots of your plants as they tend to develop large, singular roots. This is caused by limited oxygen intake of the roots from the soil - a common case found in root-bound plants.

One sure way to grow your plants healthily is by air-pruning. This method is efficient in propagating seedlings or potted plants for restoration. During the process, the roots are exposed to air without high humidity, causing the roots to 'burn off'; producing new and healthy branching roots constantly.

The same theory is utilized in the Island Grow Bag Container: the fabric of the pot allows the plants to air-prune by themselves. Your tomato container plants will now grow into their full capacity, as their growth is no longer restricted when compared to plastic pot and containers.

Contrary to plastic pots, utilizing the Grow Bag assists the plants to develop multiple small clusters of roots, making it possible for plants to receive more oxygen.

Another benefit is improved water delivery, by allowing water to flow as freely as possible through the soil and roots, at the same time carrying and distributing oxygen to all areas of the roots.

This fabric pot also effectively absorbs more nutrients than conventional plastic pots. Plant nutrients are considered precious (and expensive!) - none of it should go to waste. It can hold up to 5 gallons of soil, enough for planting potatoes, tomatoes, crops, herbs and spices, flowers, bushes and even dwarf palm trees.

EarthBox Garden Kit: Why We Love It as a Tomato Container

The patented EarthBox Garden Kit was developed by commercial farmers. It is tested and proven in the lab and farm to increase yields of vegetables, fruits, herbs and flowers, with less fertilizer, watering and no weeding at all.

This is a foolproof approach to container gardener that takes up little space, only measuring 30 x 13 x 12 inches, with a 2 cubic feet soil capacity. The box rests on four castor wheels, so that it can be easily rolled back and forth on your patio or rooftop.

The kit includes fertilizer, dolomite, two germination covers and instructions. You can use your own fertilizer, but make sure to avoid the slow release kind to avoid burning the plants.

There will be no guesswork involved as this award-winning, high-tech growing system almost does everything for you. It controls soil conditions, making use of a fertilizer strip system favorable for the growth of plants, and ensures that they get exactly the amount of water they need.

To start, all you have to do is add any brand of potting mix, seedlings and water. The black mulch sheets maintain the moisture, and a timer indicates when you should fill the reservoir with water to keep it from drying out.

The amount of water varies for every stage of plant growth, so filling the reservoir can be quick, or can take a lot of time when plants are at a stage where they take in a lot of water.

A tip is to set up a rain barrel with a 1.5-inch flexible tubing and spigot; this will help you to fill the EarthBoxes very quickly, and reuse your rainwater too!

Unlike conventional gardening, plants won't risk being strangled by weeds and got at by pests (e.g. snails and slugs), since a cover is provided to protect the plants. The cover also reflects light, keeps an even soil temperature throughout the day, and stops water from transpiring off the surface.

If you don't want to squat down every time you're tending the plants, you could build supports to hold them off the ground.

Easy set-up: All you have to do is open the box, add good potting mix, water, seeds and/or transplants

Not a structurally elegant tomato container: Looks like a cheap plastic box

Expensive: In addition to the initial cost, you have to shell out money for potting soil (more if you choose organic soil) and plants

Requires ongoing purchases: The covers need to be changed every year

Opaque water fill tube: It would've been better if the water fill tube were made of clear plastic, so that you wouldn't have to guess when it's time to fill the water reservoir

Pipes become possible breeding ground for mosquitoes: Hollow pipes with stagnant water make for suitable breeding grounds for mosquitoes. Screens should have been included in the kit to be affixed to the pipes

Preparing Your Tomato Container

We need to prepare the container before planting our tomato plants inside it. After ensuring that there is sufficient drainage, you need to consider the soil you'll be using.

If this is the first time you're using the container: Fresh soil is recommended, rather than simply filling the container with dirt from your garden.

Regular ol' garden dirt probably has weed seeds lurking, and you cannot be sure of the balance of nutrients in the soil. Starting from fresh, you will know for sure what your plants are getting.

If this is year two or beyond: It's advisable to rotate your crops. Don't grow tomatoes in the same container two years running, unless you plan on removing the old soil and replacing it fresh.

Tomato plants leech nutrients from the soil, and you probably won't get such a good crop the second year.
