Kale From GIY Ireland



All cruciferous veg (which we should be eating 2-3 times a week) are good for you, but kale is particularly nutrient dense. It’s a nutritional powerhouse in three particular areas – it is high in antioxidant nutrients, high in anti-inflammatory nutrients, and in anti-cancer nutrients in the form of glucosinolates. It is an excellent or very good source of vitamins A,C, E and K, fibre, calcium and iron. I was always somewhat put off by the fibrous nature of the leaves but once you get to know it, kale can be a useful and delicious veg in the kitchen. From a growing perspective it’s a great winter garden crop – hardy and attractive-looking and providing leaves right through the winter and early spring. If you have space for 8-10 healthy kale plants in your veg plants you will have your own abundant super-food source right at the end of the garden. Kale is in season right now..!

Sowing
Sow from April to late June. A foolproof way to grow healthy kale seedlings is to sow them in module seed trays – sow one or two seeds in each module 1.5cm deep. Thin out the weaker seedling. Kale will germinate in about a week and will be ready for planting out about 6 weeks later. Make sure to harden off early sowings carefully.

Growing
Since it is a hungry crop, add plenty of compost or manure to the soil the previous autumn. Space plants about 50 cm apart in rows about 60cm apart. Include kale in your brassica rotation – do not plant them where there have been brassicas for at least 3-4 years previously. Hoe around young seedlings regularly to keep weeds down. Slug damage can be a real issue at this stage, so do what you have to do to prevent it. Water regularly in dry weather to prevent the roots from drying out. Earthing up stems will help the plant to support itself, particularly in a windy site. Remove yellowing leaves. A fleece or net cover is essential for organic growing of kale (as with most brassicas) to keep butterflies and birds away from the plants.

Harvesting
Start harvesting from autumn and if you play your cards right you should be able to continue harvesting until mid-spring the following year. Remove leaves with a sharp knife, starting at the crown (or a quick tug downwards will do the job too). The plant will grow side shoots which you can harvest between February and May.

Recommended Varieties
Nero di Toscana, Red Russian, Redbor.

Problems
Kale is rarely bothered by the diseases that can blight other brassicas. The key issues are slug damage at seedling stage and birds/butterflies later on.

Tips

1. Water seedlings thoroughly about a day before transplanting.
2. Tread on the soil around the plants every now and then which will firm up the soil and make sure the plants don’t topple over in the wind. Like all brassicas, kale likes firm (as opposed to loose) soil.
