​Spring


Remember that the major pruning should have been done in the spring (in Western PA this is usually when or after the forsythia bloom.) However, it is never too late to prune.  

Fertilization is the most important thing you can do to get a good crop of blooms.  We suggest you use a good balanced fertilizer (10-10-10 for example).  This means it has equal parts nitrogen, potassium and phosphorus.  Manufactured for organic will work. Organic has more of the trace elements needed for healthy soil, but is your choice.  

Keep your bushes well watered ( about 1" per week) and well feed.  So far we have gotten sufficient rain fall but if we go into a protracted dry period with little rain or snow you may need to water.  This is rather unlikely till spring.

Winterizing:  The frost free date in Western Pennsylvania is in mid-May.  We have been prone to radical swings in temperature this year.  You may need to protect your bushes if we get a late freeze.

Now is the time to check mail-order Nurseries to order your new selections for spring delivery.  Popular varieties sell out quickly so the best bet is to order early and request delivery in April.   Check out our Nursery Guide for direct links to all the major mail-order sellers.  (Nursery Guide Page)
