This year’s rains prompted a lot of lush, green, succulent growth, and the aphids have responded by reproducing rapidly in even larger numbers on our roses’ new growth and buds. Why am I seeing so many more aphids on my new rose growth this year?Īphids are the first pest in the spring. If the blind shoot is vigorous and growing toward the outside of the bush, you can prune back the blind tip, which will allow the rose to try to set a bud again. When they are growing in the center of the bush, remove the stem altogether to open the center of the bush to light and air. There is nothing we can do to prevent blind shoots. They are also thought to occur because the rose is putting out more stems than it can support with corresponding blooms. It is believed that they are caused by extreme fluctuations in weather or temperatures that slow and stop the tip growth. The reason that blind shoots develop is not fully understood. Why am I seeing so many stems that terminate without a bloom?īlind shoots are short stems with no flower at the end. There is no reason to be concerned, and the bush will resume producing normal flowers when the weather stabilizes. Reasons for the imbalance are due to environmental conditions such as fluctuating weather. The cause for the strange blooms is plant hormones that are out of balance. Phyllody, or vegetative center, is an interesting bloom deformity we sometimes see in our rose garden even when the plant is otherwise healthy. Why on earth are there leaf-like structures emerging from the center of my rose bloom? Here are some questions you may have in your rose garden this May. This year’s atypical weather patterns delayed our roses’ first blooms by several weeks. April was so lacking in sun and was so gray that it was nicknamed “Gray-pril” by the National Weather Service. When it wasn’t pouring, drizzling and misting, it was cloudy, foggy, windy and cold. We love the gift of free irrigation, and our roses love the water.īut this year we had more than our usual share of rain without our usual fair share of sun. You certainly won’t hear gardeners complaining. In San Diego, it is taboo to grumble about getting too much rain.
