My rose blossoms are smaller now than they were in the early spring
Q: My rose blossoms are smaller now than they were in the early spring, I have been feeding them regularly, is there a special type of food they need?
A: No, a good all-purpose rose and flowering plant food is fine, the only special one would be if you wanted to feed and control insects at the same time. What is most likely going on is simply the time of year and the temperature in particular. Light grooming will help trim and shape the plant to keep it tidy and if you have a variety that develops the “hips” or fruit and you want to keep it on the plant, trim out the fruit, energy diverted to the fruit can slow flowering, but as the weather gets hot most varieties tend to have smaller flowers in the summer, particularly ones that have large double blossoms. Keep the plants healthy and water as needed through the summer and as the temperatures cool in the fall the large blooms will return.
