Tea rose bushes are a stunning addition to any garden. They require minimal care and produce beautiful blooms year after year. For the best results, keep the bushes well fed by feeding them at least twice during their growing season--first after pruning, and again after the first set of flowers are wilting. This technique will encourage a second set of blooms during the growing season.
Water new plants daily for the first two weeks to aid the roots in spreading out into the soil and avoiding shock.
Taper off the amount of water slowly over the next two weeks until the plant is receiving water twice each week.
Deep-water the tea rose bush weekly by filling its well one inch full and allowing the water to sink completely into the soil. For best results, deep-water early in the morning to avoid evaporation and maximize the root's absorption.
Heat the distilled water in a measuring cup for two minutes. Add the powdered fish and powdered seaweed and stir until any clumps are dissolved. Powdered fish provides the tea rose bush with necessary nitrogen, phosphorus and potassium. The powdered seaweed adds additional potassium as well as natural plant hormones that aid the flowers in resisting disease.
Add the Epsom salt and stir until the salts are dissolved. Epsom salt supplies magnesium, which aids the plant in nutrient absorption.
Add the apple cider vinegar and molasses and the coffee grounds, and gently mix until all the clumps are gone. Apple cider vinegar adds acidity to the soil, as well as trace minerals. Molasses gives the plants iron and a sugar boost to encourage vigorous blooming. Coffee grounds naturally increase and sustain a greater acidic pH, and provide a minor caffeine boost for blooming.
Pour the liquid rose food onto the roses at sunset to avoid foliage burns. Pour the mixture over the leaves and then water in the food that falls to the roots. This mixture provides enough food for four small rose plants or two large rose bushes.
Examine the tea rose bush in mid-February and make note of any frost damage or diseased stems.
Remove any suckers by pulling them by their root. Suckers are stems growing from below the bush's graft line that will take over a plant and prevent it from blooming if not removed.
Remove any diseased or dead stems with pruning shears. This cutting encourages vigorous new growth.
