In making a screen planting, two plans are possible--one, the shrub
border, and the other the hedge row, and filberts are excellent to use
in either planting. Where space is at a premium, the hedge offers the
best form of screen. Filberts planted two and a half feet apart and
pruned in such a way as to make them have a shrub appearance will make
an ideal hedge and produce lots of nuts of good quality. This hedge can
be counted on to be effective up to twelve feet in height.
In the shrub border filberts are allowed to produce many stems and to
grow into small trees. This is done by pruning and by using groups of
two or three plants in a place, planted some five or six feet apart.
Different varieties may be used for different groups, thereby producing
a variation of foliage. The filberts will take their places with the
well known small trees like the dogwood and the redbud, when used in
this way.
Still another use for filberts in landscape work is to use them for
small trees as lawn specimen plants. They have a size, shape, and
foliage that makes them attractive when used in this way.
+Cross Pollination Necessary+
Our experience has been that there is need for cross pollination to get
maximum yields of fruit; therefore, we suggest that different varieties
be used in a planting. Barcelona, DuChilly, and the Jones Hybrids seem
to us well suited for this. Of course, there are others, but our
experience with varieties is limited.
When it comes to the soil for filberts, we find that a fairly rich soil
that has plenty of moisture is the best. Of course, the soil must drain
well because the roots of filberts seem to be very susceptible to poorly
drained soil conditions. If there is a lot of sand in the soil, give the
filberts more moisture and food because they are rapid growers.
So far, we have not had many complaints about filberts suffering from
winter injury. This may be due to the fact that so far Kentucky is not
using great quantities of these plants, or it may be due to the fact
that the varieties used have been reasonably hardy. The little winter
injury seen so far has been in the terminal twig growth, and removal of
these twigs in the spring has not meant altering the normal shape of the
plant.
I do not know whether there is any significance to it but the filberts
that have been fed by using well rotted manure applied in the fall and
spaded into the top four inches of soil next spring have made the best
growth and produced the most fruit.
So far the filberts that we have had experience with have been free from
insects and diseases. One never knows how long that condition will last.
