What to do in Winter


By late December  Western Pa has settled into winter and your bushes into dormancy.  

This month is a great time to reflect on how your garden did over the past year.
Are there any of your roses that did not do well? Could they be helped by moving them
to another, better location when spring comes?  

​If you are seeking a specific rose cultivar it is advisable that you place your nursery order as soon as possible.  Many nurseries are reporting 'sold out' on many of their roses.  

You can browse all the nurseries selling on-line by going to our Nursery Guide page (the link is above). 

You can also take care of all your tools, check all of your fertilizers and your
chemicals; these chores can be done anytime during the winter. 

Enjoy the winter rest.

What to do in July/August
The typical concerns for the hot days of July and August evolve around the amount of rainfall.  The old adage that roses need one inch of water per week still holds true, although so far this year (2019) we have had more than sufficient rainfall.  Yet it is wise to get a rain gauge and check it weekly.  We will very likely get a period during summer when Mother Nature does not keep dumping the rain.  If that happens get out the hose.  H2O is the most important element you can give your roses.

Monthly fertilizer applications are also important.  We recommend a balanced organic product--such as Rosetone.  Follow the instructions on the bag carefully and remember 'more is not necessarily better.'  Keep up this routine till September.  At that point stop fertilizing so the growth rate begins to slow preparing the bush for the northern winter.  

Hot, humid summer is also black spot time.  If you are growing roses as part of your landscape design and choose highly disease resistant cultivar this will not be a major issue.  If you are growing hybrid teas, miniatures and many floribundas that are prone to black spot you will need to apply a good commercial fungicide to keep the disease in check.  Ortho and Bayer products for roses work quite well.  The organic products will work to a limited extent if applied on a weekly basis and start before the disease has gotten firmly established.
