Maintenance
🪴 Transplant
Transplant these into the garden
Move hardened-off seedlings into their final beds.
Set out 4–6 ft apart, in full sun (6–8+ hours).
🧺 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.
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 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.
🛠️ 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.
