Know before you buy
Yes, while formulated for roses, this fertilizer is excellent for all flowering shrubs and woody plants. Its nutrient profile supports the vigorous growth and bloom production required by many ornamental garden staples.
For best results, apply Rose-tone in the early spring when new growth begins. Depending on your specific plant needs, you may reapply throughout the growing season, but always follow the label instructions for frequency and dosage.
Bio-tone microbes are beneficial bacteria and fungi added to the formula to help improve soil health. They assist in breaking down organic matter, making nutrients more accessible to the plant roots for more efficient uptake.
Rose-tone is made from 100% natural and organic ingredients, making it a safer alternative to synthetic chemical fertilizers. However, it is still recommended to keep pets and children away from the area during application and to water it into the soil thoroughly.
Yes, for optimal performance, you should sprinkle the granules around the base of the plant and work them into the top layer of soil. Following up with a thorough watering helps activate the slow-release nutrients and ensures they reach the root zone.
