Trees
and shrubs are the backbone of your landscape. They are used
as screens, backgrounds and accents. Trees are used for shade,
and for fruit. Flowering shrubs provide long lasting, beautiful
blooms which brighten even the gloomiest of days.
Because
the cultural needs, the size, and the structure can vary so
greatly within different varieties of the same species of
trees and shrubbery, I recommend visiting a local botanical
garden or arboretum before deciding on your choices. Even
a leisurely stroll through your own neighborhood will provide
you with a great deal of insight into what you like, and what
grows well in your area. Trees and shrubs live and grow for
many years, so the effort is well worth the time that it takes.
(Besides, it's a great way to spend the day!)
Azaleas
Azaleas
can be very fussy about their growing conditions.. They MUST
have acid soil with a Ph of 5.0 to 6.5. They do NOT like clay
soils. The first thing I would do would be to get your Ph
tested. There are inexpensive test kits available, which will
easily and quickly tell you the Ph of your soil. Many nurseries
will test your Ph for free. If the soil is alkaline at all,
your Azaleas will be unable to access the necessary nutrients
and elements vital to their health. It will be necessary for
you to add a considerable amount of peat moss, and other organic
matter to the soil. The addition of the course builders sand,peat
moss, ground bark, sawdust, compost, or other organic amendments
will also help to break up the clay texture, and help to aerate
the soil. Be sure to feed your Azaleas with an acid type Rhododendron
fertilizer..
When you
plant Azaleas or Rhododendrons, they should be placed in the
ground so that their root ball is slightly higher than the
surrounding soil. They will not do well if soil is pushed
up against the trunk. (Could this be the problem?)
Azaleas
can be planted at any time of the year, even if they are in
bloom but it is best to plant them in the early fall so they
have a chance to adjust to their new home before winter freezes.
When you are shopping for an azalea, there are many factors
to consider. Whether it is sold in a pot with it's rootball
wrapped in burlap is of little consequence, nor is the size
of the plant. Many nurseries provide tags on their plants
which will tell you the name and blooming period, as well
as the eventual size of the plant and how cold hardy it is.
Some have fragrant flowers (mainly Exbury azaleas). Azaleas
can be low growing, and never reach a height of more than
two feet, but others can grow as tall twelve feet. You can
use these facts to your advantage and purchase plants that
will give you an extended blooming season by choosing a few
of the very earliest blooming and a few late flowering varieties.
Plantings can also be staggered by size. It is best to buy
plants which have been grown out of doors locally, which pretty
much insures that the plant is hardy in your area.
Azaleas must be grown in an acid soil, with a pH of 5.0 to
6.5. They will not tolerate lime. Many nurseries will test
your soil pH for free,, and give you recomendations. Try to
plant azaleas in an area which receives a few hours of morning
sun, but receives at least partial shade during the very hottest
part of the day. Dig your planting hole twice as wide and
1 1/2 times as deep as the rootball. Mix compost and peat
moss into the soil, and if is necessary for drainage, add
in course builders sand or grit. When you remove the plant
from the pot, use your fingers to loosen up the roots a little
to get them to grow into the new soil. Set the plant so that
the soil level is the same as it was previously growing at.
Sprinkle a small amount of rhododendron food into the hole
at the dripline of the plant. Fill in the hole and water it
very thoroughly. Azaleas resent drying out, so use some kind
of mulch to conserve moisture in the soil. You can use leaves,
bark, compost or whatever.
The buds for next years blooms will be formed this year, so
it important that the faded blooms are removed, otherwise
you will not get a flower on that stem next year. Rhododendron
food should be applied after the plant has finished blooming.
Pruning consists mainly of removing the spent flowers, and
cutting back longer branches which may spoil the symmetry
of the plant.
Year round
bloom.To have flowers in bloom all year long will take planning
on your part, using a combination of shrubs, bulbs, annuals
and perennials. Annuals Put out a large number of beautiful
flowers all summer, but they complete their life cycle from
seed to flower to seed again, all within one year. (zinnias,
marigolds, petunias......) Perennials are plants which have
a more limited blooming period, but they live and bloom year
after year. (carnations, columbine, chrysanthemums....) Here
again nursery tags can be very helpful. You can find plants
which will flower during any month of the year, and combine
them to create a year round flower show.
Rose
Roses
are very heavy feeders, so you should feed them as soon as
the new growth appears, and then then again after the first
heavy bloom using a 5-10-5 fertilizer or commercial rose food.
The how and when of pruning roses is pretty much determined
by the type of rose that you are dealing with, so I will try
to cover them all. Sucker growth (stems which originate from
below the budding union) should always be removed at their
point of origin no matter which type of rose. Pruning cuts
should always be made 1/4 to 1/2 inch above an outward facing
bud. Make your cuts at a 45 degree angle to prevent moisture
from collecting on the cut, which will cause rot or disease.
Always use a clean, sharp pair of shears.
Pruning Hybrid Tea Roses
Prune hybrid tea roses in early spring when the new growth
just begins to show. Start by removing old, winter damaged
or diseased wood, cutting it back to a healthy point. You
will want to create a somewhat cup shaped plant by removing
center stems, and branches pointing inwards. This will admit
more light and fresh air, and help to prevent mildew and disease.
Cut the remaining stems to about 1/2 of their original length,
leaving the stronger stems longer than the younger, thin ones.
Hard pruning will result in fewer long stemmed blooms than
light pruning, but if it necessary you can cut some of the
older stems back to within 6 inches of the base.
Pruning
Floribundas and Grandifloras
Prune this type of rose in early spring. Remove all criss-crossed
stems, and cut the remaining stems at various lengths leaving
the center stems longer than the outer ones to form the desired
shaped plant. Pruning the canes at different lengths will
help to insure continuous blooming.
Pruning
Ramblers
Ramblers grow a completely new set of blooming canes each
year. The flowers are formed on year old canes, which should
be cut back to within 2-3 inches of their base when they are
finished blooming. This will allow the plant to devote its
energy into producing the new shoots that will bear the next
years flowers.
Pruning
Climbers
Climbing roses resent hard pruning.In early spring, remove
any dead or diseased canes, other than that you should only
do light pruning. Climbers should be trained to grow in a
more fan shaped pattern rather than upward growth. If it becomes
necessary, the canes can be shortened at any time of the year.
Pruning
Miniature Roses
Miniature roses need very little pruning. Just prune them
to the desired shape. Cut any new shoots which have emerged
from below the soil line to about 1/2 its length. When the
branches finish flowering, cut them back to a new outward
facing bud.
Pruning
Hydrangeas
The French hydrangea, Hydrangea macrophylla, blooms from the
previous years buds, and should be pruned in the summer when
the blooms have faded. Most hydrangeas bloom on new wood so
if you decide to cut your plant back now, I would think that
it will send new buds again, but I can't promise you that.
Since it isn't necessary to prune hydrangeas every year, I
think that if it were my plant, I would snip any dead branches,
and possibly do a little shaping, but otherwise let the plant
go ahead on its own schedule.
