What’s wrong with my courgette plant?

Courgettes, marrows, pumpkins and squashes can be affected by a number of viruses including Cucumber mosaic virus causing yellow mottling, distorted and stunted growth. There is no remedy but to discard the affected plant. Resistant cultivars are available.

Why are my zucchini shriveling and dying?

If the female flowers aren’t pollinated properly, the fruit will begin to grow and then suddenly shrivel up and die. Bees and other pollinators are less active in rainy weather. Rainy weather could be responsible for poor pollination and rotting of the small fruits.

Why are my courgettes dropping off?

The most common cause of zucchini fruit falling off the plant is no or poor pollination. This means that for some reason, the flowers on your zucchini plant were not properly pollinated and the fruit was unable to produce seeds.

Why are my courgette leaves turning yellow and dying?

When the leaves turn yellow, something is interfering with chlorophyll production, and this is a clear indication that something is wrong with your plant. A zucchini leaf can turn yellow from nutrient and soil imbalances, too much or too little water, damaged roots, lack of sunlight, and several diseases and pests.

What does blight look like on zucchini?

Before you start treating, make sure your zucchini plant does have a blight problem, rather than another issue. Both gummy stem blight and Alternaria leaf blight cause brown edges or spots on the leaves surrounded by a rim of yellow. Phytophthora blight also causes brown spots, but they are darker and squishy.

Why are my courgette leaves curling?

Leaves Curl or Become Deformed

When zucchini leaves start to curl or become otherwise deformed, the first thing you should look for are aphids. But you may notice ants on your plants first, if aphids are present. The ants like to feed on the honeydew that aphids leave behind.

How often should zucchini be watered?

Water generously.

Add about one inch of water, depending on the soil moisture. If it feels too dry, add an extra inch of water. When the weather is cooler in early spring, water your zucchini about once a week, increasing to two or even three times per week once with air temperature increases.

Can you over water zucchini?

The four main signs of overwatering your zucchini plants are slow growth, yellow leaves, the appearance of mold, and fruit rotting on the vine. Too much water washes nutrients out of the soil and can leave the roots waterlogged. Giving your zucchinis just enough water to thrive is often quite a challenge.
