1. Sow or plant zucchini in a warm, sunny spot with at least 10 hours of direct sunlight daily.
2. Space seedlings 1 meter apart to ensure good air circulation.
3. In small gardens, train zucchini vines up a stake to save space.
4. Apply fertilizer monthly during summer for optimal yields.
5. Once established, add a thick mulch layer around plants to retain soil moisture.
6. Keep soil consistently moist, watering from below to avoid wetting leaves and prevent diseases like powdery mildew.
7. Aim for a soil pH between 6.0 and 7.0.
8. Pale, brownish leaf spots signal squash bugs; squash borer (Melittia cucurbitae) causes sudden wilting.
9. Harvest fruits young and small—about 3-4 cm diameter or 10-12 cm long.
10. Use a sharp knife or pruners to cut zucchini at the stem, avoiding plant damage.
Zucchini is prone to powdery mildew ("white disease"), which causes whitish, powdery spots on leaves that turn brown and drop.
To prevent it: Avoid wetting foliage, space plants well for airflow and sun exposure, and remove/burn affected leaves immediately.
For severe cases, try this time-tested remedy: Mix 10 cl cow's milk in 1 liter water; spray stems and leaf tops every 15 days or after rain.
Baking soda works too—its alkaline pH repels mildew: Dissolve 1 tsp in 1 liter water and spray leaves.
Store zucchini up to 1 week in the fridge post-harvest. Try these easy, budget-friendly recipes:
