Rose Pruning Again

Late February to early March is the time for the major pruning of roses. Back in December, I did a preliminary pruning , now is the time for the last major pruning before the spring season begins.  First, a comment on hybrid tea roses. This is what most people have in their gardens. I only have a few hybrid tea roses. These are the roses that need the most drastic pruning. Basically, you cut all the canes down to about 1 foot, making the cuts right above an outward-facing bud. The result will be something like this -  Most of my roses fall into the shrub and climbing categories. These roses are pruned differently and not as severe as the hybrid teas. For shrub roses (and many of the David Austin English roses fall into this category), I first take out the older canes completely to the ground. The older canes are easy to spot - they will be thicker and darker in color. After thinning out the older canes, I remove any canes that are damaged, crossing one another and canes that ...

No, we didn't have a baby but something much better than that entered the household over the holidays - Michael Dirr and Keith Warren's new book The Tree Book. It is a massive book - 940 pages and covers 2400 tree species and cultivars. It isn't a book that you can curl up in bed with, as I love to do, but it looks nice on the coffee table and it is excellent browsing material. It is a reference book for the plant professional (all nurseries should get a copy) or tree-loving plant geeks like myself.

Each entry gives detailed information about foliage and flower characteristics, native range, adaptability, landscape use, street tree use and descriptions of cultivars commonly seen in trade. The photos are most helpful and usually include multiple views of the entire tree seen from a distance as well as close-up shots of leaves and flowers.

The information in the book is valuable although you will have to read the individual entries closely for information concerning what areas of the country is best suited for the tree. Sometimes, only a climate zone is given, which is often inadequate. A map or even charts with references to ideal locations would have been helpful. 

Although the book contains a huge number of trees, you will not find everything. For example, I did not find an entry for Embothrium coccineum (Chilean Flame Tree) but that is a tree that only grows in this region of the U.S. On the other hand, though, another Pacific Northwest resident, the Eucryphia is listed. 

Still, this is an essential reference book and like my dilapidated copy of the earlier Dirr's Hardy Trees and Shrubs: An Illustrated Encyclopedia, I know this will be a book I will return to again and again.

  2. Its important to see a tree in multiple seasons and stages to get a real sense of it, and how it will fit in a space, be it our garden or a park. I often fall in love with a closeup picture of bark, only to realize it belong to a massive specimen I should never plant in my own garden :-D This book is a wonderful resource.
