If you’re wondering whether it’s too late to plant tomatoes in June, you’re not alone. It’s a common question for gardeners who got a late start on the season. The quick answer? It depends—mostly on where you live, your local climate, and which type of tomato you want to grow. But don’t worry, with a few smart strategies, it’s still possible to grow a healthy crop of juicy tomatoes, even with a late June start.
Let’s break it down step-by-step so you can get those tomatoes in the ground and enjoy a harvest later this summer or early fall.
Can You Plant Tomatoes in June?
The truth is, timing is everything when it comes to tomatoes. They love warm weather and hate frost. So, if you’re planting in June, you need to make sure there’s enough time for your plants to mature before the first frost hits in fall. The key is to know your local frost dates.
✅ Start by Checking Your Frost Dates
Tomatoes should be grown outdoors only after the last frost date in spring and before the first frost in fall. If you’re planting in June, the last frost has likely passed—but you still need to count how many frost-free days you have left in the season.
Tools like the Farmer’s Almanac or PlantMaps let you check frost dates by zip code. Once you know your first fall frost date, count backwards to see how many growing days you’ve got. This will help you decide whether to plant from seeds or transplants and which tomato varieties to choose.
Pro Tip: Use Transplants, Not Seeds
By June, the window for starting tomatoes from seed is likely closed unless you live in a warm zone. Instead, buy established seedlings (transplants) from a nursery or garden center. These give you a 6-8 week head start and increase your chances of harvesting before the cold sets in.
Bonus tip: Many garden centers discount their remaining tomato seedlings in June—perfect for late-season planting on a budget.
Choose Fast-Maturing Tomato Varieties
If you’re planting late, opt for varieties that mature quickly. Most tomatoes take anywhere from 60 to 100 days to ripen, but some “early” varieties ripen in as few as 50 to 65 days.
Here are a few great picks for late-season planting:
- Cherry Tomatoes – Small and quick to ripen. Try ‘Supersweet 100’ or ‘Sungold’ (55–65 days).
- ‘Early Girl’ – A reliable slicer that matures in just 50–60 days.
- ‘Juliet’ – A flavorful grape/roma hybrid, ready in about 60 days.
- ‘Northern Lights’ – A sweet, colorful beefsteak that matures in 55–60 days.
- ‘Siletz’ – A tasty slicer with a 70–75 day maturity window.
The smaller the tomato, the faster it tends to mature—perfect for gardeners racing the clock.
Give Your Tomatoes the Best Growing Conditions
Late-start tomatoes need a little extra TLC to catch up. Focus on creating the ideal growing environment:
☀️ Full Sun
Tomatoes need at least 6–8 hours of direct sunlight each day. Pick the sunniest spot in your garden or balcony.
🌱 Fertilizer
Feed your tomatoes at planting time with a balanced fertilizer, and again throughout the growing season. A tomato-specific fertilizer will provide the right blend of nutrients for flowering and fruiting.
✂️ Pruning
Prune your tomato plants to boost airflow, reduce disease risk, and direct energy into fruit production. Remove suckers (the small shoots that grow between the main stem and branches) and trim lower leaves that touch the soil.
🌿 Support
Use tomato cages, stakes, or trellises to keep your plants upright. This keeps fruit off the ground, reduces disease, and makes harvesting easier.
Protect Your Plants in the Fall

Tomatoes won’t survive frost, so as fall approaches, take steps to protect your plants and stretch the season:
- Cover them at night using row covers, blankets, or plastic domes if frost is in the forecast.
- Grow in containers and bring them indoors or into a greenhouse once it starts getting chilly.
- Use cold frames or mini greenhouses to shield your tomatoes in cooler weather.
If green tomatoes are still on the vine when temperatures start to drop, pick them and let them ripen indoors on a sunny windowsill or in a paper bag with a ripe banana to speed up ripening.
FAQs: Late Tomato Planting

A: Only if you live in a warm climate with a long growing season. Otherwise, it’s better to use transplants to save time.
Q: What’s the latest I can plant tomatoes?
A: It depends on your first fall frost date. As long as you have 60–90 frost-free days ahead, you’re good to go—just choose early-maturing varieties.
Q: Will tomatoes ripen before fall if planted in June?
A: Yes, especially if you choose quick-maturing types and provide ideal growing conditions.
Q: Can I grow tomatoes in containers this late in the season?
A: Absolutely. Containers are great for flexibility. Use a large pot, keep it in full sun, and bring it indoors if needed in fall.
Q: How can I speed up tomato growth in a short season?
A: Use transplants, pick fast-maturing varieties, fertilize regularly, prune for airflow and energy, and give plants full sun.
Final Thoughts: It’s Not Too Late!
Planting tomatoes in June isn’t ideal, but it’s definitely doable if you make the right choices. The key is to:
- Check your frost dates
- Use transplants instead of seeds
