Question 1

What are the ingredients?

Accepted Answer

It is 30-nitrogen 10-phosphate 10-soluble potash. It has everything in the mix that you need for root feeding with the measuring spoon in the box. All you need is a gallon jug to mix it in so that you don't mix it to strong and you can use extra feedings from the same jug. All mixing and feeding directions are on the box. Buy the spray for misting the leaves but don't spray the flower buds. I have city water so I buy bottled distilled water to mix it in so I don't add unwanted chemicals that can harm the orchids. One gallon goes a long way. I also bought special orchid pots from orchid.com and sit it in an old plastic whip cream bowl then add about 1/4 inch of the watering in the bowl for humidity and continual wick feeding into the wood chip mix for more of a natural balanced feeding because the roots grow up into the air and these pots have mesh bottoms to hold the mix and large side vents that the roots grow out of. My orchids bloom almost 9 months out of the year with this method and they grow like crazy. I wish I had bought the pots with open slits for easy repotting but I didn't expect them to grow so huge. Orchids also want a snugger fit than most house plants. They also Love east or north windows as long as there is indirect lighting no west or south windows without frosted sheers and no drafts from vents. My orchids are thriving in 68-72 degree temps all year round. Orchid.com also has some very good free informational videos on how to propagate and repot orchids and other information on blooming cycles. They also carry more natural potting mixtures made from different tree barks and such in different textures. Enjoy your orchids and I hope this helped.

Question 2

I just bought the last bottle at the garden center and can't get it to spray! We've moved every part we can think of. What's blocking the spray?

Accepted Answer

Most likely, you have a bum bottle.  These plastic bottles (not just Miracle-Gro, but other bottles as well), do not always work well.  I usually keep the old one until I am sure the new one works.  If it doesn't, I switch out the old sprayer top for the new bottle.

Question 3

What are the proportions of NPK in this orchid fertilizer?

Accepted Answer

30-10-10

Question 4

how many ounces is the bottle, and how long does one last for one plant?  Thank you!

Accepted Answer

The bottle is an 8 ounce bottle & is a "miniature" spray bottle (compared to most familiar spray bottles 16-oz or larger). It delivers a VERY FINE MIST (good IMO for misting plants), and the contents should probably last 3-6 months or longer for just one plant. I have not finished my first bottle yet... the fertilizer formula in this spray is a very low concentration of nutrients. I use twice a week on the foliage of two plants that I also feed once every 7-10 days with an immersion of their plastic aeration pots into an MSU feed-me formula (plus added probiotics) bath for 3 minutes, then allow to drain until no longer dripping frequently. Then I return them to outer AERATED OPEN ceramic pots that have a shallow integral saucer base, not the solid non-drained pots they came in... orchid roots need to breathe and have air flow around them.
