You're not wrong. The original MG was created for epiphytic orchids grown under
glass, and can still be bought under the names 'Miracid' and 'ProSelect'. The
NPK ratio is 30-10-10, but 90 percent of the nitrogen is bound up in urea. It
requires environmental breakdown of the urea to make the nitrogen available to
plants, so the 30 percent N figure by itself is a bit misleading.
There are still other formulations of MG. For details see 'plant food' at
Yes, but caution is advised here as well, since there are formulations with
different release rates (generally, from 3 to 18 months), and formulations with
different release rates for the individual macronutrients as well. It gets very
complicated. Detailed information is available under 'fertilizers' at
Over use is an ever-present possibility. Personally, I believe in deliberately
under-fertilizing with granular fertilizers like Osmocote, and supplementing
with water-solubles like Miracle Grow when I can. For soil beds I use mostly
compost, sometimes supplemented with water-solubles. The vegetable plantings
additionally get carefully measured small amounts of 13-13-13 since they are
almost all gross feeders. I'm willing to do these different things because for
me its only a hobby and I'm merely dabbling, but if I were growing
professionally I'd have to do many things differently, including fertilizing.
What I do now mostly succeeds (sometimes even more than I had hoped for), but a
commercial grower needs better than 'mostly' to survive.
They like plenty of water and are heavy feeders. Try some
fertilizer and water. Especially important if it's hot and
dry this time of year in your parts. As others have said,
remove the seed pods as soon as they start to form.
