Choosing the Right Location for a Raised Bed
Selecting the best location for your raised bed plays a big role in the success of tomato plants.
Here are some insights to help you pick the perfect spot for your garden bed.
Soak Up the Sun
Tomatoes absolutely love sunlight.
It's crucial to place raised beds in areas that receive full sun for at least 6 to 8 hours a day.
This ample sunlight provides the energy plants need to grow strong and produce lots of tasty tomatoes throughout the growing season.
Good Airflow Is Key
Good air circulation helps keep tomato plants healthy.
Positioning the raised bed in an open area allows gentle breezes to pass through, reducing the risk of fungal diseases by keeping the leaves dry.
However, be cautious of spots with strong winds that might damage the plants.
Convenience Matters
Placing the garden bed somewhere easily accessible makes tending to the tomatoes much more enjoyable.
Having it close to the house or along a frequently used path ensures that watering, weeding, and harvesting don't feel like chores, and it allows for keeping a close eye on how the plants are doing.
To make assembly easy, here is the raised bed kit I recommend:
Close to a Water Source
Having the raised bed near a water source is a game-changer.
Whether using a hose or setting up a drip irrigation system, easy access to water ensures that tomato plants get the consistent moisture they need, especially during hot summer days.
Avoiding the Shade
It's important to check for any structures or trees that might cast shadows over the bed during the day.
Placing a bed too close to a large tree can result in shade and competition for nutrients, which won't benefit the tomatoes.
They need all the sunlight they can get!
Mind the Ground Below
Even though raised beds are used, what's underneath still matters.
Avoid low-lying areas where water might pool after rain because good drainage is essential.
Poor drainage can lead to root rot, which can be detrimental to tomato plants.

Planning for the Future
Thinking ahead can save a lot of trouble.
Practicing crop rotation by changing what is planted in each bed every year helps keep the soil healthy and reduces pest issues.

Preparing the Soil
One of the most important steps in growing healthy tomato plants is getting the soil just right.
When preparing raised beds, focus on creating a nutrient-rich environment that gives tomatoes everything they need to thrive.
Here's how to do it.
Building the Perfect Soil Mix
Tomatoes are known to be heavy feeders, thriving in soil that's packed with nutrients.
In a raised garden, mix:
Garden Soil:
Serves as the base; opt for high-quality garden soil that's free of weeds and diseases.
Compost:
Improves soil fertility; both homemade and store-bought compost work well.
Here is the organic compost I recommend:
Organic Matter:
Materials like aged manure or leaf mold enhance soil structure and nutrient content.
By combining these elements, you create a fertile, well-draining medium where tomato plants can set deep roots.

Achieving the Right pH Level
Tomatoes prefer slightly acidic soil, with a pH between 6.0 and 6.8.
Testing the soil using a simple pH tester can determine if adjustments are needed.
Here is the one I recommend:
If the pH is too high, adding a bit of elemental sulfur can lower it.
If it's too low, garden lime can help raise the pH to the desired level.
Ensuring Good Drainage
Tomatoes don't like to sit in soggy soil.
To improve drainage in the garden bed, mix in some perlite or coarse sand.
This helps excess water flow away from the roots, preventing issues like root rot.
Here is the perlite I recommend:
Adding Nutrients
Before planting tomatoes, enrich the soil with organic fertilizers:
Bone Meal or Rock Phosphate:
Provides phosphorus for strong root development.
Here is the bone meal I recommend:
Kelp Meal or Greensand:
Adds potassium and trace minerals that support overall plant health.
Follow the recommended application rates on the packaging to avoid over-fertilizing.
Here is the kelp meal I recommend:
Introducing Beneficial Microbes
Incorporating mycorrhizal fungi or other beneficial microbes into the soil can be beneficial.
These organisms form a symbiotic relationship with tomato roots, helping plants absorb water and nutrients more efficiently.
Here is the one I recommend:
Letting the Soil Rest
After mixing everything together, it's helpful to let the soil settle for a week or so before planting.
This allows organic materials time to start breaking down and integrates all components evenly.
Mulching After Planting
Once the tomato plants are in the ground, apply a layer of mulch around them.
Mulching helps retain soil moisture, suppresses weeds, and adds more organic matter as it decomposes.
Straw, grass clippings, or shredded leaves are good options.

Selecting Tomato Varieties
Choosing which tomatoes to grow is one of the most exciting parts.
With so many varieties out there, it can be both exciting and a bit overwhelming.
Here are some tips to help pick the perfect tomatoes for your raised bed garden.
Understanding Determinate and Indeterminate Tomatoes
First, decide whether to grow determinate or indeterminate varieties.
Determinate Tomatoes:
Also known as "bush" tomatoes, these plants grow to a certain height—usually around 3 to 4 feet—and then stop.
They set all their fruit within a short period, which is great if planning to can or make sauces.
Determinate tomatoes like 'Roma' and 'Celebrity' are ideal for smaller garden beds or when a large harvest all at once is desired.
Indeterminate Tomatoes:
These are vining types that continue to grow and produce fruit throughout the entire growing season until the first frost.
They can get quite tall; some reach over 6 feet!
If there's enough space and support can be provided with stakes or cages, indeterminate varieties like 'Beefsteak', 'Cherokee Purple', or 'Sweet 100' cherry tomatoes can yield an abundant harvest over time.
Consider Your Climate and Growing Season
Your location plays a big role in which tomatoes will do best.
Short Growing Season:
In areas with a shorter summer, look for early-maturing varieties that require fewer days to produce ripe fruit.
Varieties like 'Early Girl' or 'Stupice' work well.
Here are the ‘Early Girl’ seeds I recommend:
Hot and Humid Climates:
In regions with hot nights, some tomatoes may struggle to set fruit.
Heat-tolerant varieties like 'Heatmaster' or 'Solar Fire' can be a good choice.
Here are the ‘Heatmaster’ seeds I recommend:
Disease Resistance
Losing plants to disease can be disheartening.
Selecting tomato varieties that are resistant to common issues in your area can make a big difference.
Fusarium and Verticillium Wilt:
Look for varieties labeled with 'VF', indicating resistance to these wilts.
'Better Boy' is a reliable option.
Blight Resistance:
If blight is a problem, consider varieties like 'Mountain Magic'.
Flavor and Usage Preferences
Think about how you'll use your tomatoes.
Slicing Tomatoes:
For sandwiches and salads, big, juicy slices from 'Brandywine' are excellent.
Cherry Tomatoes:
Great for snacking and tossing into salads.
'Sun Gold' is a popular choice.
Paste Tomatoes:
If making sauces or salsa, 'San Marzano' is excellent due to their meaty texture and low seed count.
Space Constraints
If space is limited in your raised garden, consider compact or dwarf varieties.
Container-Friendly Options:
'Tiny Tim' are bred to stay small but still produce a good yield.
They can be grown successfully in smaller beds and even large pots.
Heirloom vs. Hybrid
Heirloom Tomatoes:
These are old-fashioned varieties known for their rich flavors and unique colors.
They can be more susceptible to diseases but offer exceptional taste.
'Cherokee Purple' is a favorite among many gardeners.
Hybrid Tomatoes:
Bred for specific traits like disease resistance and higher yields, they tend to be more predictable and hardy.
'Early Girl' and 'Celebrity' are reliable hybrids.
Trying Something New
Each year, it's fun to try at least one new variety.
This is a great way to discover different flavors and types that might become new staples in your garden.
Don't hesitate to explore options that are less common or have intriguing names—they might surprise you!

Planting Tomatoes
Planting time is one of the most exciting moments in the gardening season.
After all the planning and preparation, getting tomato plants into the soil feels incredibly rewarding.
Here's how to approach planting tomatoes in raised beds to give them the best possible start.
Picking the Perfect Time
Timing your planting is crucial.
Wait until after the last expected frost date in your area.
I recommend using the Old Farmer’s Almanac site to determine this date for your area.
It's wise to err on the side of caution and wait an extra week, just to be safe.
Hardening Off Seedlings
If starting tomato plants indoors, it's important to "harden them off" before planting them outside.
Over a week or so, gradually introduce seedlings to the outdoor environment.
Start by placing them outside in a sheltered spot for a few hours each day, gradually increasing the time and exposure to sunlight.
This helps plants adjust and reduces transplant shock.
Preparing the Planting Holes
In the garden bed, space planting holes about 18 to 24 inches apart.
This gives each tomato plant enough room to grow and ensures good air circulation, helping prevent disease.
Before planting, enrich each hole with a scoop of compost or an organic fertilizer to provide extra nutrients.
Note:
When planting tomatoes in a raised bed, providing sufficient space between plants promotes healthy growth and airflow.
This spacing helps prevent the spread of diseases and ensures each plant has enough room to access nutrients and sunlight.
The Deep Planting Method
One technique that makes a big difference is planting tomato seedlings deep into the soil.
Remove the lower leaves, leaving only the top few sets, and then bury about two-thirds of the stem in the ground.
Although it might seem unusual, tomatoes can develop roots all along their buried stems.
This leads to a stronger root system and, ultimately, a more robust plant.
Setting Up Supports Immediately
It's much easier to install tomato cages or stakes at the time of planting rather than waiting until plants have grown.
By putting supports in place early, you avoid disturbing the roots later on.
Providing support helps keep plants upright and fruit off the ground, reducing the risk of pests and diseases.
Here is the tomato cage I recommend:
Watering Them In
After planting, give each tomato plant a good watering to help settle the soil around the roots.
Try to water at the base of the plant to keep leaves dry, which can help prevent fungal diseases.
If the weather is particularly hot or dry, consider watering daily until plants are well established.

Mulching Around the Plants
Once plants are in the ground and watered, apply a layer of mulch around them.
Mulching helps retain soil moisture, suppresses weeds, and keeps soil temperature consistent.
Materials like straw, shredded leaves, or grass clippings work well.
Here is the straw mulch I recommend:
Labeling Your Varieties
If planting multiple tomato varieties, it's a good idea to label them.
It's easy to forget which plant is which later on.
Using weatherproof labels helps keep track of each variety, aiding in monitoring performance and making it easier to save seeds from favorites.
Keeping an Eye on the Weather
The weather can be unpredictable, especially in spring.
Keep an eye on the forecast, and if there's any chance of a cold snap or heavy rain, be ready to protect young plants.
Old sheets, row covers, or even large buckets can be used to shield them temporarily.
