Preparing a Sunny Wildflower Garden
Pam Wiehagen
Adams County Master Gardener
Wildflower blossoms have been appearing throughout Adams County in
a striking display of color. Refreshing rays of bright, hot sunshine
are beaming upon us and new wildflowers are opening every day. Now is
the ideal time to begin planning a sunny, low-maintenance wildflower
garden that will reward you with blossoms from spring through fall next
year.
The first step of this endeavor is to determine a suitable location
which will receive six hours or more of sun a day and be situated where
the view will be pleasing to you, your guests and neighbors, if desired.
Garages, sheds and small outbuildings provide backdrops that are especially
picturesque when the flowers are blooming. Once a site is selected,
the next step is to decide the garden size and shape. A garden hose
or sand can be used to outline the garden.
Now it is time to deal with existing lawn or other vegetation growing
in your future garden area. The lazy gardener's way is to cover the
surface with black plastic (large, sturdy garbage bags are an excellent
choice). Be sure to cover the corners and seams with rocks or soil to
prevent the plastic from taking flight in the wind. The hot August sun
will beat down and bake the area killing the greenery underneath. Peek
occasionally, if you must, but be sure to put the plastic back in place
until October. By then, all vegetation should be dead.
Remove the plastic and hoe the ground. Compost, horse or cow manure
and peat moss are excellent sources of organic matter and their addition
improves the drainage and soil structure. In most instances it is impossible
to add too much organic matter during soil preparation. But have a soil
test made to determine the needed amendments and nutrients before you
further prepare the soil.
Kits for this purpose are available at Adams County Extension Office
for a nominal fee. Carefully follow the instructions and send your sample
to Penn State. In a few weeks you will receive the results and recommendations
for your garden plot. Follow the guidelines for the addition of fertilizer,
lime and organic matter. Shovels, hoes and tillers may be employed with
equal effectiveness. Your newly prepared garden site will now lie dormant
through late fall, winter and early spring. The ground may be left bare
or covered with plastic again.
Coreopsis lanceolata
Now is the time to start looking through seed catalogs for pictures
of wildflowers suitable for our area. A mixture comprised of annuals
and perennials should be selected. I recommend the following plant varieties
for your consideration: Calendula officianalis (Pot Marigold), Centaurea
cyanus (Bachelor's Buttons/Cornflowers), Chrysanthemum Shasta Daisy,
Coreopsis, Cosmos, Delphinium, Dianthus (Pinks/Carnations), Digitalis
purpurea (Foxglove), Echinacea purpurea (Purple Coneflower), Eschscholzia
californica (California Poppy), Gypsophila (Baby's Breath), Lupinus
(Lupine), Papaver rhoeas (Corn Poppy) and Rudbeckia hirta (Black-eyed
Susan). If wildflower seeds are available locally, they may be purchased
and stored in the refrigerator until spring. Otherwise, plan on purchasing
in early spring at local garden centers, variety or hardware stores.
Once the ground thaws and all danger of frost is past, remove plastic,
rake the area, and sow with your choice of seeds. Cover the seeds with
peat moss, water thoroughly and keep moist while seeds are germinating.
Gradually allow the ground to become drier as the plants grow but don't
allow them to wilt. Soon you will be enjoying the anticipated display
as first one flower unfolds and then the garden gradually explodes with
long-lasting color.
On stressful days, take a break and head to your new garden. Sit under
a nearby shady tree, sip lemonade and read a good book or The Good Book
while quietly watching the activity in your wildflower bed. A butterfly,
bee or dragonfly will surely be landing before too long and you may
be pleased to know that you are not the only creature enjoying the fruits
of your labor.
