May can feel like a big planting month, but what belongs in your garden right now depends less on the calendar and more on your actual growing conditions. Because my audience gardens in many different places, I like to keep this practical. Instead of planting by month alone, use your temperatures, seasonal cues, and frost timing to help guide your decisions. May is also one of those months where gardening advice can get confusing because it does not look the same everywhere.
For May 2026, The Old Farmer’s Almanac predicted that temperatures would vary by region, with many areas trending warmer than normal, but not everywhere. It also describes this as a long-range seasonal outlook, not a daily forecast, so gardeners should still check their local weather, frost dates, and actual temperatures before planting.
Some regions are expected to be warmer than normal, including parts of the Northeast, Atlantic Corridor, Southeast, Ohio Valley, Lower Lakes, Pacific Southwest, and parts of the West.
Other areas may be closer to average or cooler, including Florida, parts of the Deep South, the northern Pacific Northwest, parts of the Upper Midwest, and the northern Texas-Oklahoma region.
This is why I always recommend using your actual local temperatures, frost dates, and soil warmth before deciding what to plant.
A May garden in Florida may be completely different from a May garden in Michigan, New York, Texas, or California.
Before we get into what to plant, here are two important reminders:
USDA hardiness zone helps tell you what plants can survive winter in your area.
Frost date helps tell you when to plant.
That difference matters more than many people realize.
A lot of gardening success comes down to timing. Plant too early or too late, and plants can become stressed from the very beginning. That stress can show up as uneven growth, bolting, bitter leaves, poor fruit production, and increased pest pressure.
Direct Sow and Transplant Crops by Temperature
Some crops do best when planted directly where they will grow, especially root crops and plants that do not like a lot of root disturbance.
Other crops are easier to establish from seedlings or transplants, especially if they need a head start or have a longer growing season.
In the tables below:
Direct sow means planting the seed directly into the garden.
Transplant means planting a young plant into the garden.
A simple way to narrow it down is to look at your average temperatures.
If Your Average Temps Are Under 60°F
If your temperatures are still mostly below 60°F and you have at least 30 days of cooler weather left, you may still be able to plant some cool-season crops.
Crop | Planting Method |
|---|---|
Beets | Direct sow |
Carrots | Direct sow |
Cilantro | Direct sow |
Collards | Direct sow or transplant |
Kale | Direct sow or transplant |
Lettuce | Direct sow or transplant |
Mustard greens | Direct sow or transplant |
Parsley | Direct sow or transplant |
Radishes | Direct sow |
Spinach | Direct sow or transplant |
Turnips | Direct sow |
Just remember, if your weather is warming quickly, choose fast-growing crops and varieties with shorter days to harvest.This is especially important in May because some cool-season crops can struggle once consistent heat arrives.
If Your Average Temps Are 60 to 70°F
This range can still work for some spring crops, but be mindful of how quickly your weather is warming.
You may still be able to plant:
Crop | Planting Method |
|---|---|
Beets | Direct sow |
Carrots | Direct sow |
Cilantro | Direct sow |
Collards | Direct sow or transplant |
Kale | Direct sow or transplant |
Lettuce | Direct sow or transplant |
Mustard greens | Direct sow or transplant |
Parsley | Direct sow or transplant |
Radishes | Direct sow |
Spinach | Direct sow or transplant |
Turnips | Direct sow |
Cool-season crops may begin to struggle as temperatures rise. Heat can lead to bolting, bitterness, slow growth, increased pest pressure, and poor-quality harvests. If you are planting these crops in May, choose crops and varieties that can mature before consistent heat arrives.

If Your Average Temps Are 70 to 80°F
This range is generally better for warm-season crops.
Crop | Planting Method |
|---|---|
Basil | Direct sow or transplant |
Beans | Direct sow |
Corn | Direct sow |
Cucumbers | Direct sow or transplant |
Eggplant | Transplant |
Melons | Direct sow or transplant |
Peppers | Transplant |
Squash | Direct sow or transplant |
Tomatoes | Transplant |
Zucchini | Direct sow or transplant |
These crops usually establish better once the weather and soil are consistently warm.
This is also where soil temperature matters. Many warm-season seeds do not germinate well in cold soil. Warm-season vegetables such as tomatoes and peppers are frost-sensitive and generally need warm conditions to grow well. UF/IFAS also emphasizes using proper planting dates for successful vegetable gardening in Florida.
If your air feels warm but your soil is still cool, your seeds may germinate slowly or unevenly.
Once Temperatures Are Regularly 90°F and Above
Now it is time to be more selective.
This does not mean you cannot grow food. It means you may need to shift your focus toward crops that can handle heat better.
Crop | Planting Method |
|---|---|
Calabaza | Direct sow or transplant |
Callaloo | Direct sow or transplant |
Malabar spinach | Direct sow or transplant |
Okra | Direct sow or transplant |
Roselle | Direct sow or transplant |
Seminole pumpkin | Direct sow or transplant |
Southern peas | Direct sow |
Sweet potatoes | Transplant |
Tropical spinaches | Transplant |
UF/IFAS notes that some vegetables can perform well in Florida’s summer heat, including sweet potatoes, southern peas, cherry tomatoes, and okra. They also mention tropical vegetables like cassava and Malabar spinach as options for hot-weather gardening.
For southern gardeners, this is where crops like okra, southern peas, sweet potatoes, roselle, Malabar spinach, tropical spinaches, Seminole pumpkin, calabaza, and callaloo can become especially useful.
A Central Florida Note
Since I garden in Central Florida, May is when I become much more selective about what I start. At this point in the season, I am usually thinking less about cool-season crops and more about heat-tolerant crops that can handle our weather.
For Central Florida, UF/IFAS lists May planting options such as okra, southern peas, peanuts, chayote, roselle, tropical spinaches, calabaza, long squash, luffa, Seminole pumpkin, sweet potatoes, yuca, and amaranth.
UF/IFAS also notes that in Central Florida, May is too late to start tomatoes. That is a great example of why local planting calendars matter. A tomato transplant may still make sense in one region, while in another region, it may already be too hot to start tomatoes from scratch.
Also, if your peppers, eggplant, or other spring crops are already established and healthy, you may not need to pull them out. Some crops can continue producing into warmer weather if they are already established and cared for properly. But starting a brand-new crop in extreme heat is different from maintaining a crop that already has a strong root system.
Flowers to Support Pollinators
Adding flowers to the garden does more than make the space look nice. Flowers help attract pollinators and beneficial insects, which supports a healthier garden overall.
Depending on your weather, May may be a good time to plant:
zinnias
sunflowers
cosmos
marigolds
basil
native flowers for your area
This is especially important if you are growing crops that need pollination, like squash, zucchini, cucumbers, melons, and pumpkins.
Just as important, try to include native flowers for your area whenever possible.
Native flowers are especially valuable because they support the native pollinators and beneficial insects already living where you garden. Those insects evolved alongside native plants, so they often recognize and use them more naturally for food and habitat.
That means native flowers can help you do more than fill space. They can help strengthen your local ecosystem and create a garden that works more in harmony with the environment around it.
A few simple reminders:
choose flowers that bloom during the season you are gardening
prioritize flowers native to your region whenever possible
plant a mix of flowers for more consistent pollinator support
avoid treating pollinator plants with pesticides whenever possible
Companion planting will not eliminate pests completely, but it can help reduce pest pressure, attract beneficial insects, and support overall garden health.
Always Check the Variety
This guide is a starting point, but the variety still matters.
Not all crops grow at the same speed, and that can make a big difference in how successful they are in your garden. Some varieties are quicker to mature, while others take much longer depending on their size and growth habit. This matters even more in May because many gardeners are heading into warmer weather. If you are planting close to a seasonal transition, like heading into summer heat, faster-growing varieties are often the better choice for crops that prefer mild weather.
Before planting, read your seed packet or transplant label carefully to understand:
days to maturity
whether it should be direct sown or transplanted
whether it can be grown in a container
how much space it needs
whether it has heat tolerance
whether it has disease resistance
the conditions it prefers for best growth
For example, some cabbage varieties can take 90 days or more to reach harvest, while smaller varieties may be ready closer to 60 to 70 days. That matters because cabbage generally does not perform well in very warm temperatures. So if you are starting your garden in May and expect summer heat to arrive soon, choosing a quicker-maturing variety may give you a better chance of harvesting before the weather becomes too hot. This is true for more than just cabbage.
The variety you choose can affect:
how long the crop takes to mature
how large it gets
how much space it needs
how well it handles heat or cold
whether it is better suited for your current planting window
whether it is better for containers, raised beds, or in-ground gardens
Also remember to include companion plants and flowers to support pollinators and help with pest control.
May Garden Care Reminders
As temperatures rise, your garden care routine may need to change.
Water more consistently.
Hotter weather dries out soil faster, especially in containers and grow bags.
Mulch your soil.
Mulch helps conserve moisture, protect the soil, and reduce temperature swings.
Fertilize as needed.
Warm-season crops can be heavy feeders. Also, if you are watering more often, especially in containers, nutrients can leach out faster.
Watch for pests.
Squash bugs, aphids, whiteflies, caterpillars, and other pests may become more active as the weather warms.
Give plants enough space.
Good spacing improves airflow and can help reduce disease pressure.
Harvest often.
Crops like zucchini, squash, cucumbers, okra, and beans are usually best when harvested regularly and before they get too large.
Final Thoughts
May is a transition month in the garden.
For some gardeners, it is the start of warm-season planting. For others, it is the beginning of summer survival gardening. Before you plant, remember to check your average temperatures, frost dates, soil warmth, crop variety, and local extension planting calendar. This list is not meant to include every crop you can grow. It is a starting point to help you make better planting decisions based on your actual climate. When you understand your growing conditions and plant in the right season, you solve many garden problems before they start.
