Is there a better feeling of hope than peering out your window in late winter and seeing fresh, new greenery sprouting through the melting snow? In tempestuous climates such as Iowa’s, perennials are a popular choice for many gardens. But don’t be lulled into thinking you can plant them and forget about them until spring – there is plenty of preparation to be done to make sure your plants survive the harsh winter.
- Be sure to “deadhead” your flowering plants. This is the practice of cutting or pinching off the dead blooms or buds. By doing this, you are allowing your perennial to put all of its energy into strengthening the plant instead of producing seed.
- Spreading perennials tend to die in the middle, even as they spread out in your garden. Be sure to check for brown, dying areas in the middle of the greenery and divide and transplant your plant to keep it healthy.
- Pull weeds that might sap the nutrients around your garden, remove dead leaves and other debris and then cover the area with organic mulch. Don’t pack it down, but let it fall loosely, just to insulate and protect the base of your plant. Wait until the ground is frozen and solid before laying down mulch – if it’s still too warm, that extra layer will encourage new growth far too early.
- While rose bushes tend to be hardy, they still need preparation. Use heavy twine to tie all the stalks closer together, encircling all the outer canes. You should also mound fresh dirt around the base of each bush, bringing new dirt in and piling it a good 6-8 inches deep. You can also “tent” your roses with evergreen branches and cover with burlap to protect your bushes from dehydrating.
Iowa winters are harsh, but that doesn’t have to mean all your hard work through the spring and summer was for nothing. There are many simple steps to take to ensure the survival and continued long life of your garden.
