My Knockout Roses Are Not Blooming or Forming Buds
If it has been a long time between blooms or bud formation, perhaps they are stressed from the heat or an insect attack.If the rosebushes are new plantings, it is normal for there to be a bit longer time between bloom shows. The root systems are trying to get established in their new homes, supporting all that top growth and the blooms takes much energy. If they are new plantings water them with some water with root stimulator in it for two or three waterings about 10 days apart. If they are older plantings be sure you are not using a rose food/fertilizer that is real high nitrogen as this will create lots of foliage and few to no blooms.
