Know before you buy
The 13-0-0 ratio indicates a high concentration of nitrogen, which is essential for promoting vigorous vegetative growth and deep green foliage. It is specifically designed to support the leafy development of vegetables, flowers, and lawns.
This formula is designed for slow release, providing a steady supply of nutrients to your plants for approximately 6 to 8 weeks after application.
Yes, Greenway Biotech's Blood Meal is OMRI-listed, meaning it meets the strict standards required for use in certified organic gardening and farming.
For the best results, apply this fertilizer when soil temperatures are above 50°F. This ensures the soil microbes are active enough to break down the organic material and make the nitrogen available to your plants.
It is highly versatile and suitable for vegetables, flowers, trees, and shrubs. However, because it is strictly a nitrogen source, you may need to supplement with phosphorus or potassium if your soil test indicates a deficiency in those areas.
For optimal results, mix the granular powder thoroughly into the soil during planting or use it as a side-dress by working it into the top layer of soil around established plants. It is not water-soluble, so it must be incorporated into the soil rather than mixed into a watering can.
