我这有一篇关于RASPBERRY的文章可以看看：
What do I need to know about
grolving raspberries?
The roots of a raspberry bush are perennial, but the
canes are biennial, meaning they grow to their full
height in one year, fruit the next year, and then die. So
your pruning must take this into account.
Summer bearers send up canes in the spring that grow
during the summer, initiate buds in the fall, and become
the fruiting canes the following year; then they die.
Prune these raspberries during the dormant season late fall is a good time. Remove dead canes that ha-ve
just fruited and any weak or damaged new canes. Then,
with red, purple, and yellow varieties, cut the canes back
to 4 or 5 feet. Leave the healthiest canes spaced 4 to 8
feet apart in a hedgerow or leave about six canes per
hill. Black raspberries should also be summer topped;
that is, 2 to 4 inches should be trimmed off the top of
new canes when they are about 2 feet tall. This promotes
strong lateral shoots that will bear heavily the
next year.
Everbearers can be treated just as the summer bearers,
but it is harder to distinguish the new canes from the
old. The way to recognize the new canes (those that
bore a fall crop) is that they will have lateral, or side,
buds only at the tips of the canes, while the old canes
will have these buds farther down. If you prefer a larger
fall harvest at the expense of the summer crop, cut the
canes down to within 2 inches of the ground before
growth starts in the spring.
Where space is very limited, one
raspberry plant can be set on
either side of a sturdy post and
up to nine strong canes tied to it.
Economical use of space can
also be made by growing
raspberries in a single row
along a fence. Space the plants
about 18in apart and tle the
canes in to the fence as they
grow.
Raspberries come in red, yellow, black and purple
varieties. Some varieties are everbearing and some are
summer bearers. Red and yellow raspberries multiply
rapidly by suckering in all directions. They are a good
choice for growing in 2-foot-wide hedgerows. Black
raspberries do not sucker and propagate only by tip
rooting. These can be limited to smaller hills. purplL
raspberries can be similarly limited, although some will
sucker and fill in the row.
Although raspberries are naturally adapted to cool
climates, varieties have been developed foi virtually all
parts of the country. So buy a variety that is suitable for
your area. To avoid disease problems, don't dig up
plants from a friend; instead buy certified virus-free
plants from a nursery.
The plants can tolerate light or heavy, but not wet,
soils. They do best in rich, loose soil with plenty of
organic matter and a pH of 5.5 to 6.8 - 6.0 is ideal.
Before planting, eliminate all the perennial weeds from
the site and mix manure or tO-10-tO into the soil.
_ The plants you buy will come bare-rooted or in pots.
Soak bare-rooted plants in water for an hour bifore
planting. Cut the canes back to 2 inches above the
ground level to encourage new growth and balance the
roots. Space the plants 2 to i feet apart in rows 6 to 7
feet apart.
You may want to set stakes or posts every 2 to 3 feet
along the row and attach wire beginning 3 feet from the
ground. Then you can train the canes to grow along
these supports. Whether trellising is necessiry dependi
in part on the variety and how you prune. Most
varieties grow 5 to 6 feet tall or more and become laden
with berries. It is often easier to manage the plants if
they are trellised. Raspberry。
