Storing vegetable seeds.
If you are an avid gardener then you know that seed catalogues will
soon be showing up in the mail box. But if you are like most people, you
will have many seeds left over from the previous season. Are these seeds
still viable? Is there a good chance they will germinate if planted? You
bet. Most vegetable seeds remain viable or able to germinate for three
years or more when stored properly. A few vegetables such as spinach, onion,
and sweet corn, produce seeds that remain viable for a shorter period of
time. In any case, storage conditions are very important. It's best to
keep seeds as dry as possible. Enclosing them in a glass jar or other airtight
container may be helpful. This will also protect against insect infestation
and feeding by rodents. Although refrigeration is not necessary, keeping
seeds as cool as possible, but not freezing, will also prolong their life.
It's easy to check the germination ability of stored seeds and this might
even be a fun family project. Simply remove a set of 20-30 seeds from each
stored packet, wrap them in moist paper towels, place them in a zip-lock
bag, and keep them in a warm place (70-80F). They should germinate in a
week to 10 days. If half or more of the seeds germinated, it should be
fine to sow them in the garden. Just increase the planting density accordingly
to account for less than 100% germination. If germination is low, discard
the seed lot and order or buy fresh seeds.
It's time to think about perennial vegetables and small fruits.
March is the best time for planting many perennial vegetables and small fruits. So go ahead and place your orders as those seed and nursery catalogs begin arriving. Here are some recommended varieties that should do well in Kentucky:
As soils temperatures fluctuate resulting in cycles of freezing and
thawing, herbaceous perennials such as daylilies, iris, strawberries, and
others, may be partially lifted out of the ground. This can usually be
prevented by applying two-three inches of mulch around perennials. The
mulch helps to stabilize soil temperatures and prevents the drastic fluctuations
of temperatures exhibited by bare soils. If plants are not mulched, check
them during periods of thaw to see if any heaving has occurred. If so,
firmly push the plants back into the ground to their previous depth and
cover with at least two inches of mulch.
Woody plant care for the winter.
During periods of warm weather, continue to water newly planted trees
and shrubs as well as established evergreens. This is especially true for
plants on the south and west side of the house since they receive more
winter sun than the rest of the landscape. This brings up another situation.
If you are making plans now to transplant trees or shrubs in early spring,
consider that the light situations in your landscape may differ between
summer and winter. Areas that seem bright and sunny now may not be during
the summer.
Remember your evergreens during snow storms. Accumulating
snow, especially when wet, may seriously damage branches. A broom can be
used to sweep off snow on lower branches. An upward sweeping motion is
best, and be sure to watch out for power lines. It's better to prop up
ice laden branches than to try to physically remove the ice. Such branches
tend to be brittle in cold weather and may be damaged in the removal process.
In other words, don't beat the ice off of branches with a stick! If severe
winter damage occurs to limbs and branches, pruning can be done at any
time to remove the damaged parts. Otherwise, wait until severe winter weather
is over before doing maintenance pruning. In this way one can better judge
and remove other branches that may have been damaged during winter.
