How to Fertilize Roses in Pots: Tips for Blooming Beauties

Growing roses in clay pots allows you to enjoy the beauty of this flower even if you don’t have a garden. But unlike garden roses, container roses, and shrub roses, shrub roses need more care, especially fertilization. How do I fertilize roses in pots?

You’d better feed your container roses every spring with slow-release organic fertilizer. During the growing season, this plant needs to be fertilized monthly with organic nourishment like fish fertilizer. Besides, you should avoid applying fertilizers on rose foliage to prevent burned leaves. In this post, Flower Bed Nursery will provide you with more helpful information about rose fertilization. Let’s explore together!

How To Fertilize Roses In Pots?

You should fertilize potted rose plants every 2-3 weeks during the growing season, especially after each bloom. Due to the limited amount of soil, you will need to fertilize potted rose plants more often than garden ones. Some perfect timeframes for fertilizing will be most effective.

In late summer, nourish the roots of your plants with a slow-release fertilizer that’s low in nitrogen. Pause the fertilization about 6–8 weeks before the first frost. In spring, apply high-nitrogen fertilizer to your rose plants when new leaves appear. You can add some Epsom salt to stimulate the growth of cane and lilies. Wait until shoots are 4-5 inches in length to apply a slow-release fertilizer.

How Do You Make Roses Feed?

When planting new rose plants, add a layer of compost to the planting holes before placing the plants in. Next, care for their roots with slow-release fertilizer with the dosage as in the instructions for use. You can use this fertilizer with some bone meal to provide more nutrients for the plant.

Until the rose plants are fully established, you can fertilize them once a month with fish emulsion. Don’t use full-strength manures at this stage, as they can burn the root tips and leaf margins. Established roses require balanced fertilizers that contain three essential components: Nitrogen, phosphorus, and potassium. To have thriving and highly productive flower plants, you have to feed them with enough of these nutrients during their growing time. You can consult some ways to make homemade rose fertilizer later in this article.

How Often Should Roses Be Watered?

The frequency of watering depends on various factors, including soil types, soil mixture, monthly rainfall, weather conditions, etc. But generally, you should water the newly planted rose every two or three days and the established rose once a week.

According to experienced growers, you should water your roses when the top layer of soil is dry. In the summer, you should observe your plants to check if they need water. Wilted blooms indicate that your miniature roses need more water. When watering, it’s better to avoid blooms and foliage. Wet foliage can be the ideal condition for mildew and other fungi to grow.

How Do You Make Homemade Rose Fertilizer?

You can fertilize your roses with natural or organic ingredients, such as organic rose fertilizers. Here are some homemade fertilizing roses you can make to nourish your flowers.

Banana peels

One of the essential nutrients for roses is potassium, which is abundant in banana peels. This kitchen leftover also provides your plants with many other minerals. To use banana peels as manure, you need to grind them and apply them to the base of your rose.

Used tea leaves

Don’t discard used tea bags right away. They contain tannic acid, which is beneficial for roses. They are an ideal source of tannic acid that your rose will love. Open the tea bags and take out the used tea leaves to fertilize your flowers. You can also read more about hybrid tea roses for reference.


Your rose bushes can grow faster in acidic soil. White vinegar or apple cider vinegar can help lower the soil pH. White vinegar or apple cider vinegar are good at acidifying the soil. But you need to combine this vinegar with other ingredients to add nutrients.

You can try the following recipe to make manure from apple cider vinegar and some other things:

  • Molasses: 2 teaspoons
  • Epsom salt: 1 tablespoon
  • Apple cider vinegar: 2 tablespoons
  • Fish meal: 2 tablespoons
  • Kelp extract: 1 tablespoon
  • Water: 3 cups

Put the dry ingredients in a container and slowly add the vinegar and water, then stir well. You can use this mixture as organic slow-release manure for your rose plants at the end of summer.


We hope that our guide on fertilizing roses and using organic fertilizers in pots is helpful to you. Caring for potted and shrub roses requires more time and effort than gardening ones. But when you have vigorously blooming pots, you will know these investments are worth it. Thank you for following this post!
