Extra vigorous varieties, Climbers, and Ramblers may put all their energy into growth the first year or two and not bloom until the second or even third year. After the first year, the most common cause for low bloom production is over-fertilizing, especially with high-nitrogen fertilizers that encourage leafy growth instead of flowers. We recommend using Heirloom Founders Fish Fertilizer along with Omnimeal during the first growing season. For year two and beyond, try Heirloom Boost & Bloom for a balanced nutrient boost and Heirloom Bone Meal to support strong root development and increased blooms.
Other possible reasons include:
- Lack of sunlight: Ensure your rose gets at least 6 hours of direct sun per day.
- Improper pruning: Some varieties bloom on old wood, so heavy or untimely pruning may delay flowering.
- Soil and drainage issues: Poor soil conditions or inadequate drainage can stress the plant, reducing blooms. Adding soil conditioner can improve soil health.
- Weather conditions: Extreme heat, cold, or drought can affect blooming cycles.
- Pests or diseases: Aphids, thrips, or fungal infections can weaken the plant and hinder flower production. Check out our full line of treatments available help keep pests and diseases under control.
