September Roses
Posted in Gardening Tips on September 27th, 2011 by Sonia Uyterhoeven – 3 Comments
Many people think of June as the month for roses. And while it’s true for many, here at The New York Botanical Garden we generally have two peak seasons for our roses. They first come into their glory in late-May, with both the repeat flowering roses and the one-time blooming old-fashioned types exploding with color and fragrance throughout June.
The repeat blooming roses take charge for the rest of the season; some of them flowering almost continuously, while others take a four to six week hiatus before re-flowering.
We expect a lot from the roses in the Peggy Rockefeller Rose Garden so we pamper them as much as possible. They are fed multiple times during the growing season with an organic rose fertilizer in April, again in late June immediately following flower, and one more time in early August. Compost tea is used as an additional foliar feed throughout the season.
Cow manure and Epsom salts are added to soil in the spring, and compost and worm castings are added later in the season to create a fertile growing environment. A loyal troop of volunteers come to the Garden every week, and under the careful supervision of the Rose Garden Curator, Peter Kukielski, they weed, deadhead, mulch, water, and fertilize the flowers in this beautiful, historical garden.
