I use the 2.5 exclusively on all my plants including Adiantum ferns. A tablespoon should suffice.

Two questions:

1. Are these houseplants or kept outside?
2. What does the label say?

The Bromeliads are kept outside in 6" pots. Label doesnt mention bromeliads at all but I know that Merit is used by many growers so I wanted to hear from someone who uses Merit granules on their broms. I only used 1/2 teasp scattered around each plant because I want to be cautious with my collection and not kill any but now I'm wondering if the 0.5 strength is strong enough to prevent flyscale. I have a feeling most brom growers are using the 2.5 strength as mentioned in the previous reply.
