Zucchini Cultivation

A zucchini plant feeds a family. It also gets powdery mildew if watered from above.

1 min read

The zucchini is a powerhouse: it consumes water, absorbs sunlight, and produces more if you don't let it grow oversized fruits. In a pot, it needs 25 L and a spacious corner.

Space and Soil

One plant per large pot or 1 m² in soil. Rich, well-draining substrate. A short stake won't support it; at most, it will hold up a stem that lies down.

Watering and Powdery Mildew

Water at the base in the morning. The white underside with powder is powdery mildew: air, not nighttime foliar watering. Harvest when 15-20 cm: if you wait for the “woody zucchini,” the plant will stop.

Flowers

Male and female. If there are no pollinators, hand-pollinate with a brush in the late morning.

What We Recommend at Control Garden

25 L pot, coco-perlite substrate, and space. Zucchini is not a crop for narrow balconies.

FAQs

Why does the small fruit rot?
Lack of pollination or irregular watering. Hand-pollinate and water consistently.
Two plants together?
They shade each other and get powdery mildew. Better to have one well-fed.
Potassium soap?
For young aphids. Powdery mildew requires other strategies (air, sulfur as per the sheet, do not improvise).

Potassium soap works by contact. Wet the underside well and avoid burning in full sun.

Drainage substrate for pots

The solution to yellow swamp leaves is air in the root ball, no more fertilizer.
