Zucchini seed can be sown any time from mid March through to late May. Using a good quality soil based compost, fill 3 inch pots to within one half inch of the top of the pot. Sow two seeds per pot.

Sow seeds indoors, 1-inch deep into small pots to avoid disturbing the roots when planting them out later on.

Grow them indoors in a greenhouse or on a bright windowsill. They will be large enough to plant out after four to six weeks, so don’t sow too early.

Harden off the young zucchini plants. Plant them out after about two or three weeks once the risk of late frosts have passed. Remember to water the pots well before planting out, and avoid holding the plants by their stems as they are easily bruised.

Harden off, and plant out once the risk of frost has passed. To avoid root damage, water the plants first so they slide more easily from their pots.

Step 4: Plant Into Containers
