How to Grow Courgettes and Marrows
Growing Courgettes and Marrows
The cultivation of courgettes and marrows is the same in each case; only the size at which they’re picked is different – courgettes are simply under-developed marrows. Both are very easy to grow, given the right conditions, but, like other vegetables, they are normally raised in heat.
As for. Possible yield Varies enormously but a well-grown plant of a good variety could yield up to 13Ib (5.9) kg per plant.
Time from Sowing to harvest
10-12 weeks for courgettes, 12-15 weeks for marrows.
‘Bambino’, ‘Defender’, Sylvana’, ‘Soleil’ and many more. I must admit that I never bother to grow marrows specifically. I just let the odd courgette grow to full size, if I want one.
As for cucumbers. In addition, they may also be sown outside where they are to grow. This should be done two seeds per station with 2ft (60cm) between each plant for bush varieties, 4ft (1.2m) for trailing. Sow in the second half of May and be ready to cover the seedlings should there be the prospect of frost at night.
Those plants raised in heat can be planted outside when the risk of frost is over. Plant 2ft (60cm) or 4ft (1.2m) apart and always be ready to cover them should the weather turn frosty. Courgettes and marrows also benefit, as do cucumbers, from being planted with the rootball just proud of the ground. This helps to prevent the stem rotting where it comes out of the ground.
Keep the plants well watered all the time. To keep the weeds at bay, use arather than a hoe, thus improving soil moisture retention and avoiding damage to the surface roots.
Pests and diseases
Slugs are certainly the worst pest andthe worst disease. A problem that sometimes arises is the flower end of the ‘fruit’ going rotten. This is hard to avoid but is usually only serious in a wet summer. If you leave the dead flower on, the fungus invades it; if you take it off, the fungus invades the wound!
Technically, courgettes cease to be courgettes when they are about 6in (15cm) long. However, this could be regarded as extravagant and, in practice, they are picked and used any time after they are about 6in (15cm) long.
Marrows must be cut before there is any hint of toughness in the skin; this is usually when they are some 12-14in (30-35cm) long. The best way of judging this is to try to push your thumb nail into the skin on the creases at the stalk end. If you can’t do this with ease, you’ve probably left the marrow too long and it will now be a little too large and coarse.
Although marrows can be stored by hanging them up in a shed after they have matured, this is a waste of time; it is much better to eat them when they’re still young, tender and tasty. Always cut marrows and courgettes cleanly from the plant.
