Regardless of the type of rosebush, some rosebushes will take a bit of a rest period to store up strength and nutrition for more bloom cycles. We can actually make that rest period a prolonged period by trying to do too much. Such as when it comes to feeding the rosebushes. There are some fertilizers on the market called Bloom Boosters, I scratch my head at that name too. Most of them are very high in nitrogen which will actually cause more foliage growth and cut way down on bloom production. If you have not ever given them any of the teas, such as compost tea, alfalfa tea or Moo Poo tea, I recommend doing so. These teas build the soils home of the rosebushes as well as giving them some great nutrition that is not out of balance. I give my rosebushes some kelp meal at least once a season as well. Using some natural organic items helps build that soils home which will help in keeping the roses blooming better and longer.
