After visiting The Philadelphia Flower
Show this year, I can't help but get excited for the new planting year! Proven
Winners had a display of some of their new offerings for 2018 (see below link). There are always some fabulous new offerings but we need to prep first.
Since we are all excited to get out there & dig in the dirt anyway, it
isn't a chore but we should have a prep plan. Most of all enjoy the welcome
time outside! Follow these tips from Proven Winners:
1. Time for a spring inspection. On one
of the first warm days of spring, put on your inspector’s hat and head out to
the garden with a notepad. It’s time to see what happened in the garden while
you were indoors all winter. Take note of:
- Cold, ice or
snow damage on plants
- Beds that will
need to be cleaned out
- Hardscaping
elements—walls, fences, benches, sheds, trellises—that have shifted, bowed
or rotted
- Evidence of new
animal burrows from skunks, chipmunks, moles and voles, groundhogs or
rabbits. Also, note any deer or rodent damage on woody plants.
2. Address hardscaping issues first. In early
spring before the ground is ready to be worked, focus your energy on
hardscaping. This is the time to repair damaged retaining walls, level out your
stepping stones, clean out your gutters, and fix fences, benches, decks, sheds,
trellises, window boxes and raised beds. These tasks are easier to accomplish
while your plants are still resting safely dormant.
Early spring is also a good time to plan for and build new raised
gardens, widen existing ones, and tidy up your beds’ edging. When temperatures
allow, add a fresh coat of paint, stain or sealant to any hardscaping elements
made of wood.
3. Do a thorough spring cleanup. Ideally
just before your spring bulbs start to pop up, clean the plant debris out of
your garden beds. This includes fallen branches, matted down leaves, last
year’s perennial foliage, ornamental grasses and perennial hibiscus, and any
annuals you didn’t remove last fall. Maintaining good hygiene in your garden
beds will help to keep pests and diseases at bay.
Now is also a good time to clean out debris from your pond or
water feature. While you’re at it, scrub and sterilize your bird bath and
containers before setting them back out into the garden. A 1 part bleach/5
parts water solution should take care of any lingering diseases or insect eggs
in your containers.
4. Test your garden soil. Experts recommend testing your garden soil every 3-5 years to see
what nutrients or organic materials it needs and which it has too much of. You
might learn, for example, that your soil is very high in phosphorous, so you
would avoid adding fertilizers that contain a lot of it. Or you might find out
your soil is naturally alkaline, and need to add aluminum sulfate around your
evergreens and acid-loving shrubs like hydrangeas. Detailed instructions on how
to collect and submit your soil sample is available on your state’s Extension
Service website.
5. Feed your soil. Once you
know what your garden soil needs based on your test results, talk with someone
at your local garden center about which specific products to use, always
following package instructions for best results.
A good general practice is to topdress the soil with an inch or
two of compost, humus and/or manure in early spring just before or as your
bulbs are starting to emerge. That’s also a good time to sprinkle an organic
slow release plant food like Espoma’s Plant-tone or Rose-tone around your
perennials and shrubs. Earthworms and other garden creatures will do the job of
working these organic materials down into the soil for you.
6. Get out a sharp pair of pruners. Spring
is a good time to prune some kinds of woody shrubs and trees. We’ve created a detailed guide
for you to follow here: Pruning Demystified. Here are a few
highlights:
- Start by pruning
out anything that has been broken or damaged by winter ice, snow and cold.
Remove dead wood, too.
- Follow the
general rule that flowering shrubs which bloom on new wood (this year’s
growth) can be trimmed in spring. This includes summer flowering shrubs
like butterfly bush, smooth hydrangea (H. arborescens), panicle hydrangea (H. paniculata), potentilla, rose of Sharon, and roses. Their flower buds will be set on
the new flush of growth that appears after you prune it.
- Spring is also a
good time to shear back evergreens like boxwood and arborvitae once their initial flush of
new growth has finished emerging.
- DO NOT prune early
flowering shrubs and those that bloom on old wood (last year’s stems)
like azalea, forsythia, lilac, quince, ninebark and weigela in
spring. If you do, you’ll risk cutting off this year’s flower buds. You
might not be able to see them, but they are there, so resist the urge to
prune.
7. Divide perennials and transplant shrubs. In early
spring when they are just beginning to pop up, divide and transplant any
perennials that have outgrown their space or grown large enough to split, if
desired. In most cases, it’s best to divide and move perennials in the opposite
season of when they bloom. That means moving summer and fall blooming
perennials in spring, and spring blooming perennials in fall. This avoids
disrupting their bloom cycle.
Evergreen shrubs can be moved in early spring before their new
growth appears or in early fall to give them enough time to re-establish their
roots before winter. Deciduous shrubs can be moved almost anytime they are not
in bloom and the weather is mild, but generally spring and fall are the
preferred seasons for transplanting. If you move them while they are dormant,
there will be less stress on the plants and they will be more likely to spring
back into action quickly.
8. Put out any necessary supports like trellises
and stakes. If you’ve brought a trellis into the garage or shed for winter,
early spring is a good time to bring it back out into the garden. Make sure
it’s sturdy and apply a fresh coat of paint if needed before using it again. If
you grow peonies, delphiniums, or any other perennials that require support, set
them out now or get them ready to go. Trying to wrangle tender peony stems into
a peony ring is tough work once their leaves have unfurled.
9. Plant your spring containers and borders. Though most annual flowers need the soil to warm up a bit before
planting, some cool weather loving plants like pansies, nemesia, and osteospermum daisies won’t
mind if you plant them in the garden early. Fill your spring containers
with sweet alyssum, lobelia and Supertunia petunias,
too. You’ll find six solutions for cool weather plantings in this article. For most other annuals,
it’s a good idea to wait until your area’s last frost date to plant. Your local
Extension Service website lists that date on their website.
10. Be ready to take cover if freezing
temperatures are in the forecast. If you garden in an area
where late spring frosts and freezes are a possibility, be prepared to cover up
plants that have tender emerging buds or foliage if freezing temps are in the
forecast. If the buds haven’t begun to open yet, there’s no need to cover them. Old sheets and towels that have been relegated to the rag pile are a
good option, and professional row cover is available for purchase, too. DO NOT
cover tender plants with plastic sheeting or tarps. The effect of the plastic
touching the newly emerging buds and foliage will magnify the cold’s effect,
rather than mitigate it.
