Hi guys/gals - I've read conflicting information on the internet as to which fertilizer is best suited for a 10" potted Alstroemeria.

Some websites suggest a well balanced fert. i.e. 7-7-7 (1-1-1)
Others say an all-purpose is fine 24-8-16 (3-1-2)
Yet, others have said a bloom booster is great. i.e. 15-30-15 (1-2-1)
Meanwhile a couple others emphasized potassium (potash) being the more important factor to consider. The closest I found was a water soluble Miracle Grow (18-18-21), which I bought this morning. Says it's for tomatoes/vegis).

I have 3 miracle grows (all purpose / bloom booster / tomatoe & vegi one). Thoughts on which one & how often I should fert? The pot is 1/2 empty at this point because I read that you're supposed to pull them right out, after they are done flowering a stem.
Chances are, I'm over-thinking this but thought I'd ask.

cheers,
willow

Those flowers usually require a higher Nitrogen, which is the first number. You can use the 18-21-21 or the all purpose(all equal numbers) though. I use what I have honestly. Cut the flowering stem back or pull them out easily. Fertilize as the instructions state on the bottle, each fertilizer have different instructions. thumbup

Well, I watered with the 18-18-21 so I'll see what happens this week.
The pot is currently 3/4 empty as I pulled allot of the individual spend stems right out.
Hopefully the fertilizer will stimulate new stems to shoot up.
