GARDENING NEWS

 

 
Katy is truly multi-purpose apple tree. Not only is it a good eating apple but it is also a cooker, juicer and makes top quality cider. Is it top class for any of those purposes? The answer has to be no but it definitely does a good job at all three.

We thoroughly recommend it as a choice for newcomers to growing apple trees because disease resistance is high and it requires only minimal pruning. It grows well all over the UK but is especially valuable in cooler parts where it shrugs off late frosts with ease.


PARENTAGE OF KATY APPLE TREE


This is a Swedish bred variety from Balsgrad and dates back to 1947 although it was not released for sale until 1966. The parents are James Grieve and Worcester Pearmain.

APPEARANCE, TASTE AND CHARACTERISTICS OF KATY


A very rosy red apple which is one of the most attractive looking of all. The fruits are medium sized but some thinning may well be required to avoid production of small apples. The apples are produced early in the season (see below for specific dates) and the white blossom is well known for standing frost better than most other varieties. This makes it especially useful for cooler parts of the UK. 

This variety is an excellent pollinator of other varieties because the blossom lasts longer than average allowing for a longer pollination time.

The overall tree size is average and it grows fairly vigorously. Disease resistance is good especially as far as canker is concerned.

Taste does seem vary depending on the soil and other growing conditions. On average though this is a sweet tasting apple with a good background acidity. Most people find Katy a very pleasant tasting apple but the apples will be acidic if picked too early. Only harvest when the slightest twist of the stem leaves the apple in your palm.

This apple does not store well and is best eaten fresh from the tree. It doesn't deteriorate in storage for a week but much longer than that and it slowly begins to soften loosing its characteristic crunch and juiciness.

The skins are slightly thicker than the average apple but not enough to concern most people. It reliably produces a large crop of apples each year. This is an easy tree to prune because it produces large amounts of fruiting spurs without any special techniques at all. Follow the normal pruning procedures.

Overall tree size is of course primarily dependent on the rootstock but also on the growing conditions. On average the following tree sizes by rootstock are for a fully grown tree after 7 years:

  • M9 rootstock - pruned height 1.8m / 6ft, unpruned height 2.5m / 8ft
     
  • M26 rootstock - pruned height 2.2m / 7ft 6in, unpruned height 3m / 9ft 6in
     
  • MM106 - pruned 3m / 9ft 6in unpruned height 4m / 13ft

PESTS, DISEASES OF KATY APPLE TREES


Katy is one of the best apple tree varieties for disease resistance with no particular weak areas. The tree grows strongly so even scab is unlikely to seriously affect its health.

BUYING A KATY APPLE TREE


This apple tree variety is common in garden centres, online fruit specialists and occasionally the supermarkets / DIY stores. The supermarkets / DIY stores clearly sell these trees much cheaper compared to the specialist but you run the risk of two main problems if you buy from them. The first is that in a year or two disease problems may become apparent which were not visible at the time of purchase. This is very disappointing after such a long time. The second problem you may encounter is that the variety is not as specified on the pack.

If you are buying online from a specialist supplier then we can recommend Blackmoor who are competitive on price, quality, delivery and after sales service.
