  • This product can also be used as an organic animal repellent. 

Hi-Yield Bone Meal

  • Bone Meal is a 0-10-0 slow release organic fertilizer that is ideal for developing roots and creating a strong root system.
  • Recommended as a starter fertilizer for almost any plant.  But, works best for developing roots in spring flowering bulbs such as tulips and daffodils.  You can incorporate bone meal into each planting hole or broadcast over the entire bulb bed and watered thoroughly.
  • The “Rose Lady’s” recommendation as a soil additive when planting roses.

Hi-Yield Triple Super Phosphate

  • Having trouble getting your plants to bloom?  This product is recommended for application on plants that have a lack of bloom power.   
  • Apply as the first fertilizer application in spring.
  • Good for plants such as Wisteria, Hydrangeas and Butterfly Bush.
  • An enriched source of phosphorus; helps stimulate root development and aids in fruit and flower formation; easy to apply granular form; ideal for lawns, trees, shrubs, and vegetables.

Hi-Yield Aluminum Sulphate

  • This is best used if you need to lower the soil’s pH.
  • We recommend this product only for Hydrangeas.  Aluminum Sulphate will turn Hydrangea flowers blue or will turn pink Hydrangeas a darker purple color.
  • This product is not recommended for blueberries as blueberries need to be fertilized with a phosphate fertilizer to bear fruit.  The phosphate has a tendency to “tie-up” aluminum in the plant making this toxic to the plant after repeated applications.

Frequently Asked Questions

The leaves on my plants are turning yellow, what should I use?
After determining that insects and disease are not the cause, apply Ironite to supplement the soil with much needed iron.

My soil is very heavy clay, is there anything I can use to break it up?
Apply Garden Gypsum to heavy clay soils to break up the soil and improve aeration. If using on the lawn, be sure to get a soil test and wait for the analysis before applying.

Everyone tells me to apply lime to my lawn and garden, is this necessary?
Sometimes this is necessary to improve soil pH. But, we recommend that you get a soil test and wait for the analysis before applying lime.

I’m having trouble getting my Hydrangeas to bloom, do you have any suggestions?
The main cause for Hydrangeas not blooming is trimming at the wrong time. However, if it has been determined that this is not the cause, apply Triple Super Phosphate as directed. Phosphorus will increase the plant’s ability to bloom. This is also recommended for plants such as Butterfly Bush or Wisteria that are known not to bloom.

Should I add anything to the soil when planting spring flowering bulbs?
Bone Meal is recommended to develop deep roots on bulbs such as tulips, daffodils, crocus and hyacinths.
