About May in the garden
May is the last frost month for most of the US and the traditional time to transplant warm-season vegetables. Gardens are at peak spring beauty, and the shift from cool-season to warm-season crops is in full swing.
Transplanting tomatoes, peppers, cucumbers, and melons in most zones; last frost passes in Zones 5–6; warm-zone gardeners are harvesting spring crops and planting summer succession crops.

🧺 Harvest
Harvest these now
These crops are coming ripe — pick regularly to keep plants productive.
Pick snap/snow pods young; shell peas when pods are plump.
Pull roots while small to medium for the sweetest, most tender beets; large ones can turn woody.
Pick lower leaves and let the plant keep growing from the top.
Snip outer leaves once plants are 4–6 in tall, taking no more than a third at a time.
Cut sweet peas when the lowest one or two florets on a stem are open and pick every two or three days — frequent harvesting and deadheading is the secret to weeks of bloom, since any seed pods that form signal the plant to stop.
Pull turnips young — around 2 to 3 inches across — for sweet, crisp roots, since large ones turn woody and sharp.
Cut the bulb at the base once it reaches 2 to 3 inches across — golf-ball to tennis-ball size — when it’s crisp and sweet.
Cut the bulb at the soil line once it reaches 2–4 inches across and feels dense and firm — the best flavor and texture come before any flower stalk appears.
Pick flowers in the morning after the dew dries, just as the petals open fully and before they begin to fold back — that moment has the highest essential oil content and the strongest apple fragrance.
Pick borage flowers in the cool morning once they're fully open, snipping each star-shaped bloom from its drooping cluster with small scissors.
Pick fully open blooms in the morning once the dew has dried, choosing the deepest-colored flowers at peak freshness.
Pick the outer leaves first and let the center keep growing for a steady supply over weeks, or cut the whole plant 2 inches above the soil and it will flush a second growth.
Pick fava bean pods when they are plump and the beans inside feel round through the pod wall, but before the inner skins turn gray and leathery — that stage means past peak sweetness.
🛠️ Maintenance
Keep the garden growing
Mid-season upkeep keeps plants healthy and productive.
📌 Water deeply and less often, mulch to hold moisture, side-dress heavy feeders, scout for pests, and succession-sow quick crops.
