Zucchini plants require consistent moisture and proper care to thrive and produce a bountiful harvest. Even beginner gardeners can successfully grow zucchini by following essential guidelines for watering, feeding, and addressing common problems.
Watering is crucial for zucchini plants due to their large leaves and fruits. Aim to water zucchini at least once a week, providing 5-7 liters of water per bush. Avoid creating overly saturated conditions, as poor soil ventilation can lead to rotting.
Proper care involves more than just watering. Periodically loosen the soil and mulch with wilted grass to retain moisture and suppress weeds. Avoid using fresh sawdust for mulching, as it can deplete nitrogen levels in the soil. Water zucchini at the root level, preferably in the early morning or late evening, using water that is not excessively cold.
Feeding zucchini with appropriate nutrients is essential for healthy growth. Zucchini plants have a high nitrogen demand due to their substantial green mass. Providing nitrogen and potassium, especially during planting, is beneficial. A one-time feeding in June can further boost yields. Use diluted fermented grass or cow manure (1:10 ratio) or follow package instructions for complex mineral fertilizers. Always water the plant with plain water before applying fertilizer, using approximately 3 liters per plant.
Yellowing leaves and rotting fruits are common problems that require attention. Immediately remove any affected leaves or ovaries. Yellowing can be caused by various factors, including natural resource depletion, sunburn, nitrogen deficiency, improper watering, or fungal diseases.
When leaves turn yellow gradually, it’s often a natural process as the plant develops. Simply remove the affected leaves. Yellow spots may appear due to sunburn, which can be addressed by adjusting watering practices. Nitrogen deficiency can cause leaves to lose their bright green color, which can be corrected with nitrogen fertilizer. Both insufficient and excessive watering can harm zucchini plants, so maintain a balance.
Fungal diseases, promoted by poor ventilation and high humidity, can cause rot. Treat fungal issues with biological products containing Bacillus subtilis bacteria, applying them 2-3 times a month, especially in the late evening.
