Last fall, concerning the secondary blooming, the shrubs performed quite well. Only here and there, flowers were observed at the tips of the branches. With varieties from Canadian breeding, I didn’t notice it at all.
Essentially, the summer was exceptional compared to previous years, with abundant rainfall potentially extending vegetation and limiting autumn swelling. It seems that after harvesting, we shouldn’t ignore the shrubs and should water them properly in case of drought.
After harvesting the fruits, I will try applying irrigation and nitrogen to some early Russian varieties that have a greater tendency for secondary flowering.
