Hi Lupine! That must of been me. This is what I wrote on the "Indoor Care of Bougainvilleas" thread:

I get the 21 gram slow release Agriform pellets (20-10-5 plus minors) at a feed store where I buy pigeon seed, pet food, pine bark mulch, lawn fertilizer,etc., so they know me well. They sell them for 30 or 35 cents singly, but they charged me $65 for a box of 350 pellet this year, up from $55.

You can also buy them individually at plant nurseries, but in my experience, unless you do a lot of business with them they usually want more than the feed store for a box, but you can ask.

I put them around everything in the spring, but be sure and water very well when you use them.

Happy gardening!

It was you, RoseLee. Thank you so much. Susan
