FOR ESTABLISHED ROSES: Early to mid-spring is the ideal time to begin fertilizing your roses. This is when new leaves start to emerge, signaling the start of the growing season. Fertilizing at this time will provide the necessary nutrients to support healthy growth and vibrant blooms throughout the season.
To give your roses a jump-start in leaf development, it is recommended to use a high-nitrogen fertilizer for the first application. Nitrogen is essential for promoting lush foliage and vigorous growth. Look for a fertilizer with a higher first number on the label, indicating a higher nitrogen content. This will provide the necessary nutrients to support the initial leaf development.
Alternatively, you can also choose to top dress your roses with alfalfa meal, which has a nutrient ratio of 5-1-2. This natural fertilizer is rich in nitrogen, phosphorus, and potassium, providing a balanced nutrient boost for your roses. Simply sprinkle the alfalfa meal around the base of the rose bush, avoiding direct contact with the stems or leaves, and lightly work it into the soil.
In addition to nitrogen, it is beneficial to include epsom salts in your fertilization routine. Epsom salts are rich in magnesium and sulfur, which are important for promoting new cane development and overall plant health. Dissolve 1 tablespoon of epsom salts in a gallon of water and apply this solution around the base of the rose bush, thoroughly soaking the soil. Repeat this application every 4-6 weeks during the growing season.
It is important to note that every garden and rose variety may have different nutrient requirements. It is always a good idea to conduct a soil test to determine the specific nutrient needs of your roses. This will help you make informed decisions about the type and amount of fertilizer to use.
As a passionate gardener myself, I have found that following a regular fertilization schedule for my roses has significantly improved their overall health and performance. By providing them with the nutrients they need at the right time, I have seen a noticeable difference in the size and quality of blooms, as well as the overall vigor of the plants.
To summarize, early to mid-spring is the best time to start fertilizing established roses when new leaves begin to emerge. Choose a high-nitrogen fertilizer or opt for top dressing with alfalfa meal (5-1-2) to support leaf development and overall growth. Don’t forget to include epsom salts to encourage new cane development and promote lusher foliage. Remember to consider individual nutrient requirements by conducting a soil test, and adjust your fertilization routine accordingly. Happy gardening!
