Well, here we are again with another Michigan Winter/Spring.  With unseasonably warm temperatures in February and below normal temperatures in early March, many people are remembering spring of 2012 when Michigan almost lostt it's entire apple crop.  Fortunately, most of the trees and shrubs are still dormant and, at least for now, I think we are safe.  Once buds start swelling and showing color, we will need to be mindful of any severe temperature drops and freezes as this will affect the plants.  It is important to keep in mind that leaves that are damaged by late frosts and freezes will re-flush.  If the blossom buds are hit, you may lose the flowers and any fruit for the season, but the plant will be fine.  Old sheets thrown over your tree or shrub can help protect the tender growth on anything your are concerned about.  If you are growing fruit trees, dormant oil should be applied before the buds show green tips but when temperatures will remain above freezing for at least 24-48 hours.

     Late winter and early spring is a great time to do any pruning that may be needed.  Most plants can easily be pruned now, with the exception of spring flowering shrubs, birch and maple trees. Prune spring flowering shrubs such as forsythia, lilac and early blooming hydrangea after they have finished blooming.  A good rule of thumb is if they bloom before the end of May, wait till they're done.  Maple and Birch have heavier sap flow in the winter so summer is a better time to prune them.  Due to the increase in Oak Wilt, Oak Trees should not be pruned between mid-April and mid-July as this is when the disease is spread.  Remember to use sharp tools to prevent tearing of plant tissue. 

     Birds will soon be looking for a place to nest, so think about putting up a bird house.  This is a great way to encourage the birds to stick around.  You can also encourage pollinators by putting up bee and insect habitats.  Believe it or not, there are more than 450 types of bees in Michigan.  Although many people fear being stung, most are not aggressive and simply want to be about their business.
