apple 'Katja'

eating / dessert apple (syn. apple Katy)

Product Image
Easy to eat, and easy to grow, ‘Katy’ needs little introduction. A staple of children’s lunchboxes for decades, this attractive medium-sized apple, usually bright red over a light green-yellow background, is very juicy, mild in flavour and in a good year, has a hint of strawberry.

A bonus for gardeners is this variety produces an abundance of blossom over a long period, so is very useful to aid in pollinating other apple varieties.

Pollination information: This apple belongs to pollination group 3, so you will need to plant one other different variety of apple to guarantee cross pollination, and a subsequent bumper crop. Ideally this should come from the same pollination group, however it is possible to use one from group 2 or 4 as well.

How to care for apple Katja:

When planting your apple tree, prepare a hole up to three times the diameter of its root system. Fork over the base of the pit in readiness, incorporating plenty of organic matter into the backfill and planting hole. Place the plant in the planting hole and carefully refill, firming the soil around the roots to eliminate air pockets. Insert stake at this point if required.

Avoiding frozen and waterlogged soil, trees should be planted out as they arrive. If you've ordered a bare root tree, soak the roots in a bucket of water for half an hour prior to planting - or if this is not possible, they can be heeled in temporarily, covering their roots with soil, or potted up.

Keep the base of the tree weed free, fertilise at the beginning of each year water regularly during hot, dry spells.

The main prune should be done in the winter as long as it isn't frosty or freezing. Take out the 3D’s (dead, dying and diseased wood) and create an open shape. Then reduce the leaders back by a third. Aim to create an airy structure without any crisscrossing branches.

In August summer prune. Shorten any side shoots (or laterals) which are longer than 20cm back to three leaves. This will allow the sun to ripen the fruit and encourage more fruit buds. Make sure that the growth you’re cutting away feels firm to the touch.
