What are the ingredients in this fertilizer?

It is poultry manure, and feathers composted, no odor and it is very concentrated, therefore takes small amount for best results!

How often do you feed your vegetable plants with this product? It does not say on the bag.

My Mom who has a very green thumb said sprinkle it on before watering every 3-5 weeks during the sunny time of year, then not at all during the darker months so they have some dormancy.

Why isn’t Sustane 4-6-4 fertilizer available in the 20 and 50lb. bags?

You can purchase it in 5#, 20#, and 50# bags. Shipping cost are why I buy in 5# bags on Amazon, otherwise a 50# bag cost $90.00 plus $29.00 shipping,
