Sowing Months Flowering Months Harvest Months

Keep well watered throughout the season. Feed and mulch regularly.

Sow April to May. Sow seeds 2cm ( 3/4in) deep in 7.5cm (3in) pots of good seed compost at 21- 25C (70-77F). Place in a propagator or seal container in a polythene bag until after germination which takes 5-7 days.Seeds can also be sown direct outdoors once the soil has warmed. Do not sow in cold soils. Sow 2 seeds every 90cm (36in) and thin out to the best seedling. Ideally grow under cloches until the plant is established.

Gradually acclimatise to outdoor conditions for a few days before planting out after all frost risk has passed, 90cm (36in) apart each way.

Easy and great tasty results 2016-12-08

These grew easily and prolifically. Taste is superb. One of the tastiest winter squashes available IMO. Kept the trailing shoots pruned back, so each plant diverted it's energy into no more than 4 fruit. It's not as rampant as some squash, so fairly easy to keep in check.

Potty about pottimarrons 2016-12-02

This was a real surprise in 2015. I pruned it to maximise energy to fruits. Allowed 3 squash per plant and had 3 plants. Started them off in pots, then transferred to pockets manured earlier in the seasoon. Used old pizza boxes to mulch for retaining moisture and weed suppression. Has a 2 litre lemonade bottle with the bottom cut off upside down on a bamboo cane near the root/planting pocket. Watered daily, fed weekly. As fruit formed, placed them on tiles. Resulting fruits are delicious and kept for a few months as I stored in cold frost free place away from pests. Definitely one to grow again.

Star of this season 2015-06-09

Just like Grace says, why grow butternut when you can grow these. They taste similar to butternut, but mature and ripen much more quickly, without suck a thick skin. If you take the time to trim/prune them properly, then around 3 squash from each plant is what you'd expect. They look like slightly smaller pumpkins. Roasting them is the way to go, 45 mins or so and they're perfect. Will definitely grow again next year.

So tasty! 2015-01-28

Why grow butternut when you could grow these? They are very tasty and the flesh is a lovely orange colour which looks great in soup. They are fantastic roasted and the skin is thin and good to eat too, which makes them very easy to prepare. I think I got 10 from 3 plants and still have one looking healthy in store at the end of January.

Great squash 2014-08-11

These were brilliant.. Each plant produce around 3 fruit. The taste is lovely and they took practically no looking after once planted out. My allotment neighbours have been raving about them so need to plant more next year.
