rudbeckia goldilocks and becky
I have some quart potted rudbeckias cultivars goldilocks and becky that are bulked up and in bud. I'm trying to finish them for a garden fair on June 1st and 2nd. The hot weather is cooperating but I'm wondering if I hit them with a bloom boost or starter fertilizer will that help hurry them up with those buds a little bit? I've been using 20-20-20 thinking of hitting them with 8-45-10.
Pros and cons?
