FREQUENTLY ASKED QUESTIONS
Q What is bone meal fertilizer best for?
Bone meal excels at promoting root development, flowering, and fruiting. It's ideal for bulbs (tulips, daffodils), transplants, root vegetables, and flowering plants like roses. The high phosphorus content (15%) triggers blooming while calcium (24%) strengthens cell walls and prevents disorders like blossom end rot in tomatoes.
Q How long does bone meal last in soil?
Bone meal is a slow-release fertilizer that continues feeding plants for 3–4 months. One application at planting typically lasts an entire growing season. The nutrients become available gradually as soil microorganisms break down the organic material. Note: bone meal works faster in warm soils (≥50°F) with active microbial life.
Q Can bone meal burn plants?
Low risk of burn when used as directed. Its slow-release nature provides gentle, sustained nutrition. However, excessive amounts can raise phosphorus levels too high, potentially interfering with micronutrient uptake, so follow recommended rates and consider soil testing.
Q Is bone meal good for tomatoes?
Absolutely! Bone meal is excellent for tomatoes. The phosphorus promotes strong root systems and fruit development, while the 24% calcium content helps prevent blossom end rot. Apply 2 tablespoons in each planting hole at transplant time.
Q When should I apply bone meal?
Apply bone meal at planting time for best results. Mix it into the soil before planting or add to planting holes. For established plants, work it into the top 2" of soil in early spring as growth begins. Fall application works well for spring bulbs.
Q Will bone meal attract animals?
Yes, the smell can attract dogs and wildlife. Always mix bone meal thoroughly into the soil and water in well after application. Store in sealed containers and consider using it in fenced areas if animals are a concern.
