Wake up dormant hydrangeas with these tricks to ensure massive summer blooms

plant health, and they can be used with hydrangeas as well. Coffee grounds add nitrogen to the soil, while eggshells provide calcium.Use these amendments sparingly—just a thin layer of coffee grounds around the base of the plant and crushed eggshells mixed into the soil. Too much can alter soil pH and nutrient balance, so moderation is key.10. Use Epsom Salt and Compost Tea to Fuel Bigger BloomsEpsom salt, rich in magnesium, is often used to encourage flower production. Dissolve 1 tablespoon of Epsom salt in a gallon of water and use it to water your hydrangeas once a month during the growing season.Compost tea, another gardener favorite, can provide a nutrient-rich boost. Soak a bag of compost in water for a day or two, then use the liquid to water your plants. This organic fertilizer can help increase blooms and improve overall plant health.11. Protect Swelling Buds From Late Frost ShocksLate frosts can be devastating to hydrangeas, especially as buds begin to swell in spring. Keep an eye on weather forecasts and be prepared to protect your plants with frost cloths or old blankets on particularly cold nights.Cover the plants in the evening, making sure the cover extends to the ground to trap warmth. Remove the covering in the morning once temperatures rise, to prevent overheating and ensure they receive sunlight.12. Train and Support Stems Now for Massive Summer Flower HeadsAs hydrangeas grow, their large, heavy blooms can cause stems to droop or even break. Early spring is the best time to start training and supporting these stems. Use plant supports, such as stakes or cages, to encourage upright growth.Gently tie stems to the supports with soft garden ties to avoid damaging them. Regularly check and adjust the ties as the plant grows to ensure they are not too tight.13. Color-Hacking: Adjust Soil pH Early for Blue or Pink BloomsHydrangea color can be influenced by soil pH. For blue blooms, the soil needs to be more acidic (pH 5.2-5.5), while pink blooms require more alkaline conditions (pH 6.0-6.2).To lower soil pH, apply garden sulfur or aluminum sulfate according to package instructions. To raise pH, add lime. Start these adjustments in early spring to give the amendments time to take effect before blooming season begins.14. Rescue Stressed Hydrangeas With Shade Cloth and Anti-Stress CareIf your hydrangeas show signs of stress, such as wilting or yellowing leaves, they might need additional protection. Use a shade cloth to filter intense sunlight and reduce heat stress.Additionally, consider anti-stress treatments such as plant tonics or foliar sprays designed to help plants recover from environmental stress. Ensure your hydrangeas have adequate water and nutrients to support their recovery.
