Sow courgette seed indoors from April to May for transplanting later on, or direct sow outdoors from late May to June. Prepare the soil in early spring by adding plenty of well rotted farmyard manure to improve its structure and fertility.
Indoors, sow seed at a depth of 2cm (¾") in 7.5cm (3") pots of free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 20-25C (68-77F) until germination which takes 5-7 days. Do not exclude light, as this helps germination. Once germinated, grow courgettes on in cooler conditions until all risk of frost has passed and courgette plants are large enough to be transplanted. Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting courgettes outdoors in rich fertile, well drained soil in full sun at a distance of 90cm (36") apart. Cover with a protective netting or fleece to prevent attack from birds and insects. When growing courgettes, a thick mulch of organic matter spread around the plants will help to conserve moisture at the roots.
Alternatively direct sow courgettes outdoors at a depth of 2cm (¾") and a distance of 90cm (36") apart. Sow 2 seeds per hole and thin out the weakest seedling per station after germination.
Water courgettes regularly - do not allow the soil to dry out as this will impair their development. Hoe between plants regularly to prevent weeds from establishing. Courgettes appreciate an application of a high potash fertiliser every two weeks during the growing season. Hand pollinating courgettes is not usually required when they are grown outdoors. However, for indoor cultivation the female flowers can be fertilised by pressing a male flower against them. Begin harvesting courgettes from midsummer onwards when they are 10cm (4") long. Regular harvesting will encourage more courgettes to be produced. Culinary note: Courgette flowers are edible and can be eaten cooked or added raw to salads.

The seeds are expensive when compared to some varieties but these are worth it. Here we are at the end of May and I am already picking courgettes and the plants are only two feet tall!. This should be an interesting summer for courgettes, looks like I shall have to dig out all those old recipes for courgettes again.
Thank you for your review and for taking the time to share your wonderful comments. I hope we can continue to be of service.
Day of the Triffids
By helena Sierakowska 12-09-2013
I have to laugh. I was thinking Triffid when I went to write this but have been beaten to it twice! A very productive plant but be warned . I did not train mine up and one is now 15 feet long taking up the entire side of my polytunnel. Great if you have the space, but I will stick to a more compact variety next year.

Triffid is a more appt name for this plant. After many years of only a few weeks of success fruiting from other varieties these plants are a joy to grow, if only I could reach the top which gre over the green house roof. Highly recommend them
By Matt Akers 27-08-2012
Black forest is the perfect name to discrible this variety as that is exactly what i found in place of my greenhouse after returning home from a holiday.Left to there own devices these tasty triffids will grow way past the 120cm height it states on the packet. Huge yield of tasty fruits and beautifull flowers!
Climbing and still going strong
By Jo Whelton 09-11-2011
I write this in November (having yet to experience a frost) at which time my plant is still growing strong and producing courgettes having, with support, scaled a trellis and grown onwards to a length of over 12 feet whilst consistently providing a harvest along the way. Unlike other varieties grown at the same time, the stunning dinner plate size flowers produce courgettes that have resisted fungal attacks. I will certainly grow again and have no hesitation in recommending.
Excellent courgette for small spaces
By Katherine Ball 20-09-2011
These courgettes seem to cope with damp conditions so much better than any other, so we find we get a much bigger crop than any other kind of courgette. They do need to be tied in but they take up less space than a normal courgette - they certainly get my vote when choosing a courgette variety
WHAT A CLIMBER!
By DIANA GOODEY 13-09-2011
Have grown this climbing courgette now for three years over an archway - one plant eitherside - they meet in the middle at the top and cross over. They produce lovely, flavoursome courgettes all summer and well into the autumn if it is kind and make a most unusual arched entrance into my veg patch especially when in flower. I would recommend this courgette to anyone short on space - it is worth cultivating and always produces well.
True climbing courgette
By Helen Arnold 28-09-2010
We have grown these courgettes very successfully on a trellis fence this year. (We have heavy clay soil, which has been improved with some well rotted manure, but it's still extremely heavy and prone to waterlogging.)
They look great in flower, and have produced a reasonable crop of beautifully sweet tasty fruits, with no bitterness at all.
Powdery mildew has set in now, but we'll be growing them again next year as a decorative feature as well as a worthwhile food crop. - Highly recommended.
