Courgettes Yellowing
Each year I prepare the soil well when I plant my courgettes. However, the first six or so emerging courgettes go yellow at flower end and don’t grow any further. Most courgettes after this are okay. What am I doing wrong?
Sorry to hear you are having trouble with your courgettes. These plants prefer a hot, sunny, reasonably dry position in the garden; with moist, free draining soil. If your soil is waterlogged you may need to add in more compost or a vegetable mix to help with drainage. Prior to planting it can also be beneficial to mound the soil slightly to reduce the possibility of the plant getting too wet via rain or irrigation.
Courgette plants do suffer from fungal diseases if the weather is wet or they have been overwatered. This can cause discolouration, impair development of fruit and also encourage blossom end rot, which can cause the fruit to yellow and rot on the plant. It is better that a courgette is on the dry side rather than excessively wet. But of course, don’t let the plant dry out.
Comparatively low nutrient loving plants and providing the soil has been prepared well before planting, courgettes should grow well. You can apply Daltons Premium Vege & Herb Fertiliser once fruit starts to form.
