Good fertilizer for flowering plants
This fertilizer was recommended to us by a nearby plant nursery that we buy most of our potting plants. The fertilizer is easy to use and the plants do well with it. Buying in the larger container size reduces the cost per usage. One tub lasts us an entire season.
