How to grow your own Kalettes® in your urban garden

March 1, 2017 4:03 pm

Now you’ve tried Kalettes® , the natural hybrid between Brussels sprouts and kale, you’re bound to have fallen in love with their flavour and versatility. But the season of the vegetable of the moment is coming to an end in just a few weeks, and you’ll need to wait until November to bring their characteristic flavour back to your table again. Feeling nostalgic already? Don’t get downhearted, because you can make the wait more bearable by growing your own Kalettes®  at home.


Growing your own Kalettes®

The creation of urban allotments is a burgeoning trend that is beneficial for the environment and brings us closer to the land, apart from being a great idea to get your children interested in vegetables. “In the last ten years, we’ve seen a significant increase in sales to suppliers who supply garden centres, and this is closely related to the growth in private allotments,” acknowledges David Rogers, Sales Director at Tozer Seeds, the British vegetable breedingcompany that has developed the product.


When to plant your Kalettes®: 5 tips for a successful harvest

Just when the product is disappearing from the supermarket shelves is the ideal time to buy your seeds. “Mid-March is the optimum time to sow Kalettes® ”, says Rogers. “Kalettes®  should be sown in cell trays. Use a good quality seed sowing compost and lightly cover the seeds.

Water them well and don’t let them dry out. Grow them on for four weeks under glass before hardening them off for another two. They can then be planted out.”

The plant grows in a similar way to Brussels sprouts. The leaves of the plants start falling in early autumn – which means they will soon be ready to harvest. You can accelerate the harvesting phase of Kalettes®  by removing the leaves yourself.

– Like other Brassicas, Kalettes®  grow better in nitrogen-rich soils.

– They grow best in fertile soils with a pH of 6.5-7.5.

– You should leave a space of 18” between plants and, if you are organizing them in

rows, a space of 24” between rows.

– There are three varieties of Kalettes® : Autumn Star, Christmas Rose and Snowdrop,

all of which come to fruition between October and March. You can sow them at the

same time and they will mature naturally at different times (sold to hobby market customers as Kalettes® Garden Mix).

– The natural yield per plant is around half a pound.
