Tomatoes are one of the most common plants in the backyard garden. They are popular because they are fairly easy to care for, can be highly productive under the right conditions, and many varieties do well in containers or raised beds. In fact, growing tomatoes in raised beds is a great way to grow tomatoes in small spaces or accessible gardens!

With so many tomato varieties to choose from, have some fun and make themed beds like a salsa garden, or choose to include tomato companion plants. One of the many joys of gardening is harvesting what you like to eat, so choose a dish and try to produce all the main materials you need.

Growing tomatoes in raised beds is a little different than growing tomatoes in the ground. You need to change a few things in your gardening regimen and you need to make sure your bed is deep enough. But in a short time, you can start growing tomatoes in your raised beds.

Tomato Basics

You know tomatoes: round, red and juicy. Tomato, eggplant eggplant, has become one of the most consumed fruits in the world. It is eaten fresh, cooked, used in sauces and canned for later use. You'll find tomatoes in popular dishes around the world, using them in amazing ways to create all sorts of unique flavor combinations.

Garden tomatoes come in many shapes and sizes. Spherical red tomatoes are an easy-to-recognize classic form, but they can come in many shapes, sizes, and colors. Tomato plants can form a rainbow, producing red, pink, burgundy, orange, yellow, gold, green, purple, black, blue, or variegated fruit. Tomatoes can be near-perfect spheres, long and slender, bite-sized, burger-sized, smooth or lumpy. There are many types to choose from!

There is no specific variety that is best for raised beds, but all tomato plants require some specialized care in a raised garden setting. If space is an issue, grow tomatoes in raised beds, which tend to be dwarf varieties or established. In the case of pergolas, even tight spaces can allow indeterminate varieties to climb high in the garden.

Throughout history, people have avoided tomato because it was considered poisonous. The idea is not too far-fetched. Eggplant Eggplant belongs to the nightshade family and consists of many poisonous plants. Eating large amounts of tomato plant leaves can cause digestive and nervous system problems, so stick with the fruit!

Growing tomatoes in raised beds

Growing tomatoes in raised beds is a little different than growing them underground. You may find it easier to grow tomatoes in raised beds because they are more readily available, but you need to be mindful of the moisture in your garden beds. Let's consider some of the things that make a tomato plant a little different in raised beds.

when to plant

Germination of tomato seeds can be achieved in several different ways. Start seeds indoors under grow lights a few weeks before the last frost. This gives you plenty of time to nurture the seedlings before the nursery bed planting time.

Once you've planted tomatoes that are at least 4 inches tall and have maintained nighttime temperatures of 50 degrees or higher, it's time to harden your plants and transplant them into the garden. Soil in raised beds tends to warm faster than ground beds, so this gives you a longer growing season. The cold frame ensures that the seedlings will grow and will not be affected by the weather.

planting site

A quality raised bed will ensure you can place your plants exactly where they should be. Tomatoes need good sun exposure and can benefit from some kind of wind resistance. Plan a location where your trellis or tomato cage works well without inadvertently shading other plants.

One of the great things about raised beds is that you can grow tomatoes almost anywhere. If you only have a concrete patio, a raised garden bed may be ideal. Fill with good soil and grow! If you're renting, put down a piece of plastic first so you don't stain the concrete with soil.

How to Plant

When planting, the main goal should be to make sure your tomatoes are supported in place. This will become critical as your tomato plants will need extra support!

Tomato spacing is also important. There should be about 18 inches between tomato plants, so that the roots have enough room to spread out. On a 4'x4' raised bed, placing one plant in each corner should leave enough room for four plants with plenty of room to grow.

Plant tomatoes deep as they form additional roots along the stem. Your loft bed should be at least 12 inches deep. The more roots that form along the stem, the easier it is for the tomato plant to absorb water from the soil in the raised bed.

Tomatoes grow amazingly with very little care. Much of your work will go into garden soil preparation or other pre-planning. Let's explore the ideal conditions for growing tomatoes!

sun and temperature

Tomatoes thrive when they receive 8 hours or more of direct sunlight a day. The ideal temperature for tomatoes is between 70°F and 85°F. If the temperature is over 90°F, the shade cloth will work in their favor in the afternoon until it cools down.

Tomatoes grow in USDA zones 3-10, but are sensitive to prolonged exposures below 60°F. For early-season plants, a cold frame may be beneficial until the weather warms up in the garden. Wrap plastic around the outside of the tomato cage to create a short-term cold frame for very young plants to protect them from accidental frosts.

water and humidity

Water tomatoes early in the morning because if their leaves get wet it will dry out the tomato plants, and earlier the better! Use a soaker hose or drip irrigation on the roots.

Your raised bed drains faster than a subterranean bed because most use a well-draining soil mix. Therefore, you may need to water more frequently. In hot weather, you definitely need to provide extra moisture so the garden doesn't dry out. Aim for 1-2 inches of water per week, but let the moisture of the soil be your guide.

A big problem for many raised bed gardeners is cracking. Usually, this is caused by sudden overwatering, as the skin of the fruit cannot grow as fast as the plant can pump the water in. To avoid this problem, maintain consistent soil moisture in your garden.

Mulch around plants to prevent weed growth, reduce soil moisture evaporation, and regulate soil temperature.


Another benefit of raised beds is that you can optimize your soil. Tomato plants need rich, fertile, well-drained soil rich in organic matter. Start with sandy loam soil and mix in other organic matter like worm castings, compost, or forest products to retain moisture, or choose a premade raised bed mix that includes what your plants need to succeed. Mixing compost into a premade mix can also improve it.

Tomatoes prefer slightly acidic soil with a pH between 5.5 and 6.5. Test your soil each year to see which nutrients it is lacking and how to amend the soil for the next year. Good crop rotation is recommended, even in raised bed gardens, as any common tomato fungi that may be living in the soil will have time to dissipate.

Tomatoes do not do well with poor soil quality. Avoid hard-packed clays or soils that lack a good organic content. Avoid compacting the soil as this will reduce root development.


Fertilize them in raised beds at the beginning of planting tomatoes, and later in the season when they bloom. Start with a high nitrogen fertilizer, such as 10-5-5, and switch to high phosphorus and potassium later for results.

Slow-release organic granular fertilizers are ideal for raised beds. Tomatoes generally need fertilizer regularly throughout the growing season, especially if your soil is not rich. Check the manufacturer's recommendations and modify them to suit your garden and its needs.

pruning and training

Pruning tomato plants is necessary. On a raised bed, your vegetables are closer together than they are in the ground. Therefore, you need to ensure good aeration. Without aeration, diseases such as fusarium wilt can spread through your plants.

Remove the lower leaves as the tomato plant grows. The suction cups should also usually be removed to reduce the amount of extra trimming required. Keeping an eye out for suction cups should be a regular gardening activity as they can be removed quickly and easily.

Use plant ties to secure garden plants to cages or trellises. Placing them about a foot to a foot and a half apart will provide support for your plant as it loads produce.

growing problem

Both too much and too little watering can be a major problem.

Too much water can cause problems with fungal root rot or split tomatoes. Too little will result in reduced fruit growth and make the plant less healthy and vigorous. In summer, too little water can also cause severe wilting.

Finally, wild fluctuations in watering consistency can lead to rot at the flowering end, as tomatoes need soil moisture to absorb nutrients from the soil.

Keep your vegetables watered consistently and regularly, but only enough to ensure healthy growth. Provide good drainage to allow excess water to drain away. In addition to good drainage, a layer of mulch can reduce the evaporation of soil moisture.

Temperatures over 90°F can cause tomatoes to drop flowers. Overall production will decrease. Providing shade cloth can help prevent the loss of yellow blooms in summer and support healthy plant growth. Look for something that provides at least 40 percent shade to best protect your tomato blossoms.


Aphids, spider mites and whiteflies suck sap from plants. Both of these irritating pests can be treated with neem oil or insecticidal soap. For severe infestations, pyrethrins can be used to reduce their numbers. Handling these also keeps them away from other vegetables!
