Pollination

It is always good to encourage pollination. There are some plants that will attract hoverflies and bees that are the insects that pollinate the best.

The plants that best attract them are:

- Marigold
- Nasturtiums

It is good to plant any of the above close to the tomatoes to ease the pollination.

Courgettes

Courgettes are also called zucchini. 

In a culinary context, the courgette is treated as a vegetable, which means it is usually cooked and presented as a savory dish or accompaniment. Botanically, however, the zucchini is an immature fruit, being the swollen ovary of the zucchini flower.

Courgette is one of the easiest fruits to cultivate in temperate climates. As such, it has a reputation among home gardeners for overwhelming production. One good way to control over-abundance is to harvest the flowers, which are an expensive delicacy in markets because of the difficulty in storing and transporting them. The male flower is borne on the end of a stalk and is longer lived.

While easy to grow, courgettes, like all squash, requires plentiful bees for pollination. In areas of pollinator decline or high pesticide use, such as mosquito-spray districts, gardeners often experience fruit abortion, where the fruit begins to grow, then dries or rots. This is due to an insufficient number of pollen grains delivered to the female flower. It can be corrected by hand pollination or by increasing the bee population.

The courgettes need a neutral high rich organic soil. They need warmth and shelter so in Ireland it is a good option to plant them inside the polytunnel.
