ESPALIER
Espalier is the training of a tree to be decorative as well
as producing fruit. They do not require any special skills
by the grower, but take time to achieve good results.

Hints and Tips
PRUNING REDCURRANTS
Red and white currants differ from blackcurrants in that they
produce most of their fruit on fruit spurs which appear on older
wood. These fruit spurs appear clustered closely at the base of
side shoots and therefore when training try to create a goblet shaped
bush with 8-12 main branches growing upwards and outwards bearing
short fruit spurs. Laterals that develop on the main branches should
be shortened in winter to induce fruit spurs. Terminal growth of
branches should be tipped.
PRUNING BLACKCURRANTS
Once planted the Blackcurrant should be cut down to ground level.
This hard pruning at planting time results in strong new growth
from the base, fruit is borne on 1 year wood. During the first summer
strong young branches should develop, but there will be no suggestion
of fruit at this stage. The first winter after fruiting, remove
a 1/4 to 1/3 of the wood, cutting right back to ground level. Once
established, remove about 1/3 of the bush cutting out weak, damaged
or crossed over branches. Cut back old fruiting branches to a strong
shoot. Pruning can be carried out after autumn leaf fall and before
spring bud burst. Blackcurrants require lots of nitrogen such as
fresh poultry and cow manure.
LEAF CURL
Leaf curl is a common fungal disease of peaches and nectarines.
The disease over winters in the buds of infected trees and infects
in cool wet spring/summer weather.
These infected leaves are puckered, curled and much thicker than
usual. Control is an application of a copper-based fungicide soon
after pruning and just before bud burst in spring followed again
10-14 days later. Once you notice the symptoms it is to late to
control the disease in those leaves but you can apply a light dressing
of quick acting fertiliser such as sulphate of ammonia to encourage
new leaf production.
*** All our trees are sprayed with a copper-based fungicide before
being dispatched***
