You don’t need a full-blown garden to grow tomatoes. Regardless of your access to real estate, you can use a patio planter for tomatoes anywhere you have a sunny spot, whether it's on a balcony, deck, driveway, porch, rooftop – even a fire escape.
And a patio planter for tomatoes is a great gift, too!
There are plenty of helpful tips for growing tomatoes in pots. You need pick a sunny location. Choose small tomato varieties. Create a watering schedule.
But growing tomatoes in pots starts with choosing the pot.
And this decision takes special care. Tomatoes are a unique crop, particularly if you plan to grow them in containers. With so many pots and containers available to choose from, how can you know what to look for in a patio planter for tomatoes? These tips will help.
A common gardening mistake is to select a pot that is too small. When you’re choosing a patio planter for tomatoes, the bigger the better. Tomato plants are heavy feeders and have large root systems. If a container is too small, the plant’s roots get crowded and fight for water and nutrients. Rootbound tomato plants produce fewer fruit, get stunted, or wilt.
The most successful container gardeners choose larger containers that hold 5 gallons or more in volume. Even varieties that are supposed to grow well in 1- or 2-gallon pots will likely do better in a larger pot. When in doubt, choose a larger pot rather than smaller.
How big? Here are good tips to follow:
When first planted, your tomato plants will look dwarfed in a large pot. Give them a few weeks. They bush out and gain height quickly. By mid-season you’ll be thankful you chose a large pot.
If you have plenty of space, or if you want to grow more than a couple of container tomato plants, you may consider choosing a raised bed. Your raised beds can be as large or small as you choose. A good rule of thumb to follow is that they should be no wider than 4 feet on one side. This allows you to reach in from both sides to weed, cultivate, and harvest plants.
When you choose a patio planter for tomatoes, check for good drainage.
Tomatoes grow fast and they build deep root systems. They need plenty of water. Roots can only extend so far and are halted by the container’s sides. Containers dry out quickly because their sides limit soil and water volume. On the other hand, if planters have no way to drain properly, a tomato plant’s roots can become water logged and vulnerable to root rot.
Holes in the container bottom allow excess water to drain properly. A drip tray like the one used on the large outdoor planter above can help protect the surface beneath it from water rings and damage. A drip tray also allows the plant’s deep roots to continue to absorb water excess water before it evaporates.
Fabric containers, of course, don’t need drainage holes. But their porous texture means they dry out even faster than other types of planters.
That’s one reason all containers, regardless of material, should also have enough room at the top to allow for adequate watering. You may also want to consider a simple and affordable deck irrigation kit or a drip irrigation kit for container gardening. You can even set the drip hoses on a water timer.
The most common container materials are terra cotta, clay, plastic, wood, concrete, fiberglass, composite, cast iron, and metal. Fabric, too, is beginning to grow in popularity.
Natural materials lend themselves to good circulation, which is useful for preventing the spread of fungi, tomato blight, and powdery mildew in growing tomatoes.
But before you run out to purchase your favorite look for your patio, consider a few practicalities. Terra cotta and unglazed pottery can dry out quickly. Also, extreme changes in temperatures can make pottery crack more easily than other materials. You may need to replace clay pots more often than containers made of something else and monitor tomatoes in these containers often to make sure they get enough water. And while fabric containers won’t shrink and expand in the same way as pottery, they are less long-lasting and porous, too.
On the other hand, a plastic patio planter for tomatoes can easily withstand freezing and thawing. And plastic retains water more effectively. The only challenge is a container made of black plastic, which absorbs excessive heat. Tomato Dirt’s recommendation: choose a plastic patio planter for tomatoes.
If a plastic container doesn’t convey the look you want in your patio garden, you can pot up tomatoes in plastic pots and insert them into a more attractive container made of wood, metal, terra cotta, or other material. Make sure both containers have adequate drainage.
Raised beds provide an attractive planter alternative for growing tomatoes. They’re set above the soil line but allow roots to extend deeply into the soil beyond their raised edges. Keep in mind, though, that you are not able to move raised beds that are built in a permanent spot.
That’s one reason a movable elevated patio planter is becoming an increasingly popular option. And if you have physical challenges, you might consider a no-bend patio planter. The ideal height is up to you. Some gardeners, particularly the elderly or disabled, prefer raised beds that are waist high.
By using an elevated planter like the VegTrug line of products you can grow plants at an easy working height and avoid bending or kneeling. VegTrug’s V-shape allows you to grow tomatoes and other deep-rooted crops at the center and companion plants around the edges.
A self-watering tomato planter is a movable container that solves many of the choices you need to make about choosing a patio planter for tomatoes.
