Growing Cucumbers

Give a cucumber vine something to climb and it’ll reward you with straighter fruit, drier leaves, and a lot less bending over to pick. They’re one of the most reliable producers in our garden all summer long.

How to Grow Cucumbers

Planting

Direct-sow after soil has warmed past 65°F, generally late April through May here. We grow ours up a trellis or cattle panel whenever we can, it keeps the fruit straight, keeps the leaves drier, and it’s a lot easier on your back at picking time. Sow seeds an inch deep, about 6 inches apart along the trellis line.

Watering & feeding

Consistent moisture matters more with cucumbers than almost anything else we grow, uneven watering is the main cause of bitter fruit. Water deeply 2–3 times a week and mulch heavily to hold that moisture through July and August. Feed every 3 weeks once the vines start running.

Harvest

Pick often, every day or two once they start, cucumbers left on the vine too long turn seedy and signal the plant to slow down. Watch for cucumber beetles early in the season; they’re more than a nuisance because they spread bacterial wilt, which shows up as a vine that suddenly wilts even in wet soil and can’t be saved once it takes hold. A floating row cover until flowers appear keeps beetles off the youngest plants. For a fall crop, sow a second round in mid-July; it’ll keep producing right up to first frost.

Grows Well With

Cucumbers do well planted near beans, which fix nitrogen in the soil, or beside sunflowers for a little afternoon shade. See all our companion planting pairs →

When to Plant

Direct sow May through July. Watch for cucumber beetles as it heats up. See the full planting calendar →
