Fertilizing
How-tos : Fertilization for Established Plants
Established
plants can benefit from fertilization. Take a visual inventory
of your landscape. Trees need to be fertilized every few years.
Shrubs and other plants in the landscape can be fertilized yearly.
A soil test can determine existing nutrient levels in the soil.
If one or more nutrients is low, a specific instead of an all-purpose
fertilizer may be required. Fertilizers that are high in N,
nitrogen, will promote green leafy growth. Excess nitrogen in
the soil can cause excessive vegetative growth on plants at
the expense of flower bud development. It is best to avoid fertilizing
late in the growing season. Applications made at that time can
force lush, vegetative growth that will not have a chance to
harden off before the onset of cold weather.
Light
Conditions : Full Sun
Full
Sun is defined as exposure to more than 6 hours of continuous,
direct sun per day.
Watering
Conditions : Normal Watering for Outdoor Plants
Normal
watering means that soil should be kept evenly moist and watered
regularly, as conditions require. Most plants like 1 inch of
water a week during the growing season, but take care not to
over water. The first two years after a plant is installed,
regular watering is important for establishment. The first year
is critical. It is better to water once a week and water deeply,
than to water frequently for a few minutes.
Planting
How-tos : Planting Shrubs
Dig
a hole twice the size of the root ball and deep enough to plant
at the same level the shrub was in the container. If soil is
poor, dig hole even wider and fill with a mixture half original
soil and half compost or soil amendment.
Carefully remove shrub from container and gently separate roots.
Position in center of hole, best side facing forward. Fill in
with original soil or an amended mixture if needed as described
above. For larger shrubs, build a water well. Finish by mulching
and watering well.
If the
plant is balled-and-burlapped, remove fasteners and fold back
the top of natural burlap, tucking it down into hole, after
you've positioned shrub. Make sure that all burlap is buried
so that it won't wick water away from rootball during hot, dry
periods. If synthetic burlap, remove if possible. If not possible,
cut away or make slits to allow for roots to develop into the
new soil. For larger shrubs, build a water well. Finish by mulching
and watering well.
If shrub
is bare-root, look for a discoloration somewhere near the base;
this mark is likely where the soil line was. If soil is too
sandy or too clayey, add organic matter. This will help with
both drainage and water holding capacity. Fill soil, firming
just enough to support shrub. Finish by mulching and watering
well.
Problems
Pest : Caterpillars
Caterpillars
are the immature form of moths and butterflies. They are voracious
feeders attacking a wide variety of plants. They can be highly
destructive and are characterized as leaf feeders, stem borers,
leaf rollers, cutworms and tent-formers.
Prevention and Control: keep weeds down, scout individual plants
and remove caterpillars, apply labeled insecticides such as
soaps and oils, take advantage of natural enemies such as parasitic
wasps in the garden and use Bacillus thuringiensis (biological
warfare) for some caterpillar species.
Pest
: Leaf Miners
Leaf
Miner is actually a term that applies to various larvae (of
moths, beetles, and flies) that tunnel between upper and lower
leaf surfaces, leaving a distinctive, squiggly pattern. A female
adult can lay several hundred eggs inside the leaf which hatch
and give rise to miners. Leaf miners attack ornamentals and
vegetables.
Prevention
and Control: Keep weeds down and scout individual plants for
tell-tale squiggles. Pick and destroy these leaves and take
advantage of natural enemies such as parasitic wasps. Know the
Growing Degree Days (GDD)* for your area to target insecticide
sprays when most beneficial for controlling the specific leafminer.
Seek a professional recommendation and follow all label procedures
to a tee. *GDD numbers should be available from your local Cooperative
Extension office.
Miscellaneous
Glossary : Evergreen
Evergreen
refers to plants that hold onto their leaves or needles for
more than one growing season, shedding them over time. Some
plants such as live oaks are evergreen, but commonly shed the
majority of their older leaves around the end of January.
Glossary
: Shrub
Shrub:
is a deciduous or evergreen woody perennial that has multiple
branches that form near its base.
