Your Complete Guide to Planting Tomatoes, Herbs & Vegetable Gardens in May
If there is one thing that signals the true start of gardening season in Hood River, Oregon, it’s tomato planting time.
By May, garden beds begin filling with fresh herbs, vegetable starts, climbing trellises, and hopeful plans for summer harvests. Warm afternoons return, the greenhouse buzzes with excitement, and local gardeners begin asking the same question:
“Is it finally safe to plant?”
At Good News Gardening, one of our favorite local rules of thumb has been passed down for generations: keep an eye on Mt. Defiance. Once the snow has melted from the mountain, it is usually safe to plant your summer garden in the Hood River Valley.
Of course, every season varies slightly, but that old gardener’s wisdom still holds true surprisingly often.
Whether you are planting your very first tomato plant or expanding a full backyard vegetable garden, May is one of the most important months for setting your garden up for success.
Why May Is the Best Time to Plant Tomatoes in Hood River
Tomatoes thrive in warm soil and consistent nighttime temperatures. While spring days may feel warm earlier in the season, tomato plants struggle when nighttime temperatures dip too low.
In the Hood River Valley, May is typically when conditions become much more favorable for planting warm-season vegetables like:
Tomatoes
Peppers
Basil
Cucumbers
Squash
Zucchini
Beans
Tomatoes especially benefit from waiting until the danger of frost has mostly passed. Cold soil can stunt growth, weaken roots, and slow production for weeks.
If you want strong, productive plants later in summer, patience in spring pays off.
Choosing the Right Tomato Varieties
One of the best parts of tomato season is choosing which varieties to grow. Different tomato plants perform better depending on your garden space, cooking habits, and sunlight conditions.
Popular tomato categories include:
Slicing Tomatoes
Varieties like Early Girl and Beefsteak are fantastic tomatoes for sandwiches and burgers!
Cherry Tomatoes
Sweet Million and Cherry Falls are two varieties we carry that are always reliable producers with sweet flavor and quick harvests.
Paste & Sauce Tomatoes
You can't go wrong with a Roma or a San Marzano when you're looking to create delicious sauces and pastes.
If you're gardening in a smaller space or patio, many of these tomato varieties can perform beautifully in containers with proper watering and support!
How to Plant Tomatoes Successfully
Tomatoes are heavy feeders and strong growers, so planting them correctly early on makes a huge difference.
1. Choose a Sunny Location
Tomatoes need at least:
6–8 hours of direct sunlight daily
Warm soil
Good airflow
More sunlight generally means:
Better fruit production
Sweeter tomatoes
Healthier plants
2. Prepare the Soil
Healthy soil creates healthy plants.
Before planting:
Add compost or organic matter
Loosen compacted soil
Mix in a balanced vegetable fertilizer
Tomatoes prefer nutrient-rich, well-draining soil that retains moisture without becoming soggy.
3. Plant Tomatoes Deep
Unlike many garden plants, tomatoes can develop roots all along their buried stem.
Plant each tomato deeply by removing lower leaves and burying much of the stem underground. This encourages:
Stronger root systems
Better drought tolerance
More stable plants
4. Add Support Immediately
Install cages, stakes, or trellises at planting time.
Waiting too long often damages roots later in the season. Proper support also improves airflow and helps prevent disease.
Watering Tomato Plants the Right Way
Consistent watering is one of the biggest secrets to successful tomato gardening.
Tomatoes prefer:
Deep watering
Consistent moisture
Fewer shallow waterings
Irregular watering can contribute to:
Blossom end rot
Cracked fruit
Stress and reduced yields
Mulching around tomato plants also helps regulate soil moisture and temperature during warmer months.
Common Tomato Growing Mistakes
Even experienced gardeners occasionally run into tomato trouble. A few simple adjustments can prevent most common issues.
Planting Too Early
Cold soil slows growth dramatically.
Overwatering
Soggy roots can lead to disease and weak plants.
Crowding Plants
Poor airflow encourages fungal problems.
Forgetting Fertilizer
Tomatoes are nutrient-hungry plants and benefit from regular feeding throughout the growing season.

We strongly recommend:
Applying mulch around vegetables and herbs
Setting up irrigation systems early
Watering deeply instead of lightly
Feeding container plants regularly
Protecting new transplants during extreme heat spikes
Mulch is especially helpful in the Hood River climate because it:
Retains moisture
Protects shallow roots
Reduces temperature swings
Suppresses weeds
A Gardening Tradition Passed Down Through Generations
At Good News Gardening, gardening knowledge has always been rooted in local experience.
One of our favorite pieces of planting wisdom came from John Hergenrather, the original owner of Good News Gardening and uncle to current owner Jon and his wife, Hollie Gardner. His hand-drawn planting schedule has helped generations of local gardeners know when to plant successfully in the Hood River Valley.
Even today, those local rhythms still matter. Gardening in Hood River is unique because elevation, wind, temperature swings, and mountain weather patterns all influence growing conditions from neighborhood to neighborhood.
That is why local gardening advice makes such a difference.
