Ultra Bloom 0-10-10 (15 lb bag)

For the Development of Flowers and Fruit Buds

Ultra Bloom is formulated without nitrogen to aid in the development of flowers and fruit buds. Although it may be used on all plants throughout the year, it is especially recommended for Azaleas, Camellias, and Rhododendrons when flower buds begin to form in late summer, fall, and winter.

  • Blended with humic acid and beneficial soil microbes, including mycorrhizae.
  • Derived from bone meal and potassium sulfate; analysis 0-10-10.
  • Application Rates:
    • Azaleas, Camellias, Rhododendrons (to support flower development) — Apply 1 Tbsp per foot of height or width of the plant. Apply each month from bud formation through the flowering period.
    • Fruit & Citrus Trees (to support flower bud development and enhance fruit sweetness) — Apply 3 Tbsp per foot of tree height. Apply monthly.
    • General Applications (to improve flowering and root development) — For large areas, apply 2 lbs per square ft. For individual plants, apply 2 Tbsp per foot of plant height or width.
  • Scatter over the soil surface, work into the soil (except for Azaleas, Camellias, and Rhododendrons to avoid root damage), and water thoroughly.

Ultra Bloom 0-10-10: The Ultimate Plant Nutrition

Every gardening enthusiast knows the importance of providing their plants with the right nutrients to ensure optimal growth and abundant blooms. One product that has gained popularity among gardeners is Ultra Bloom 0-10-10, a specialized fertilizer designed to promote flowering and fruiting in a wide variety of plants.

The Science Behind Ultra Bloom 0-10-10

Ultra Bloom 0-10-10 is a carefully formulated fertilizer that provides a balanced blend of essential nutrients for your plants. The three numbers on the packaging, 0-10-10, represent the ratio of nitrogen (N), phosphorus (P), and potassium (K) in the product. In this case, the fertilizer is rich in phosphorus and potassium, with zero nitrogen content.

Phosphorus (P) plays a crucial role in promoting root development, flower formation, and fruit production. Potassium (K) helps plants withstand environmental stresses, improves disease resistance, and enhances the overall quality of fruits and flowers. By providing these essential elements in the right proportions, Ultra Bloom 0-10-10 boosts the reproductive and fruiting capacity of your plants.

Benefits of Using Ultra Bloom 0-10-10

  1. Abundant Blooms: Ultra Bloom 0-10-10 is particularly effective in encouraging plants to produce more flowers. Whether you have roses, tomatoes, or fruit trees, this fertilizer helps your plants bloom more profusely, resulting in a visually stunning garden.

  2. Improved Fruit Set: For fruit-bearing plants such as tomatoes, peppers, and strawberries, Ultra Bloom 0-10-10 can increase fruit set. You'll enjoy a bountiful harvest with larger and juicier fruits, thanks to the added potassium.

  3. Enhanced Disease Resistance: Potassium strengthens plant cell walls, making them more resistant to diseases and pests. Regular application of Ultra Bloom 0-10-10 helps fortify your plants against common garden threats, reducing the need for chemical treatments.

  4. Root Development: The phosphorus in this fertilizer stimulates root growth, ensuring your plants have a strong foundation for absorbing water and nutrients. Healthy roots translate to stronger, more vigorous plants.

Application Guidelines

Using Ultra Bloom 0-10-10 is straightforward, but it's essential to follow the recommended guidelines for the best results:

  1. Timing: Apply Ultra Bloom 0-10-10 when your plants are in their flowering or fruiting stages. This is typically during the spring and summer months, but always follow the specific recommendations for your plant type.

  2. Application Method: You can apply this fertilizer by broadcasting it evenly over the soil surface or by incorporating it into the soil. Follow the recommended dosage on the packaging, as over-application may cause nutrient imbalances.

  3. Watering: After applying Ultra Bloom 0-10-10, water your plants thoroughly. This helps the nutrients penetrate the root zone so your plants can access them efficiently.

  4. Repeat as Needed: Depending on your plants' needs, reapply Ultra Bloom 0-10-10 every 4–6 weeks during the growing season. Be mindful of each plant’s specific requirements and adjust your schedule accordingly.

Ultra Bloom 0-10-10 is a specialized fertilizer that can significantly enhance the flowering and fruiting capabilities of your plants.

    Ultra Bloom is just what I need this time of year

    This time of year my veggies and flowers need a boost for late summer and early fall crops and flowers. This type of product is very hard for me to find here in Maine. I don't have the time to do the liquid application every two or three weeks and Ultra Bloom is granular, easier to apply, and lasts longer. I applied a small amount to all my veggies and flowers needing the boost and then we had a couple of days of good Maine rain. WOW! It really did give my gardens the boost they needed. The squash, cucs, melons, peppers, tomatoes, and eggplant blossoms are off the chart and the young veggies are looking wonderful! I give away veggies to friends, neighbors, and the local food pantry. The food pantry is in for a good fall donation. It makes me feel good my love of gardening is giving some of my food insecure neighbors and towns people GOOD FRESH FOOD! Ultra Bloom is only one target product offered at Grow Organic.
