MSU Orchid Fertilizer 13-3-15 (Greencare) 1/2 Pound, Scoop Included, Excellent for Orchids, Anthuriums, Philodendrons and all tropicals

I ordered the larger bag in the past. Liked it a lot as it made one of my Hoyas bloom for the first time ever in 2024, and it makes leaves a deep rich green.One word of caution with this item. I let this sit too long (months) and the color became washed out with a strong smell, so I pitched it. I also purchased the K-Lite and that one is doing great with no hardening or strong smell.

Excelente

So I had two orchids, one that was dying and one that was not doing so great. Did not know anything about growing orchids. Didn't realize I was starving them by not giving fertilizer. When I started using this product the one that was dieing started growing new leaves and the one that wasn't doing so great is now growing new stems for flowers. Amazing transformation.

This is, hands down, the best orchid fertilizer I’ve ever used. I use weakly/weekly (1/4th tsp every week). My orchids flower for so long that I eventually have to cut off a still-blooming flower stalk so the plant can start the dormant cycle. The flowers come back bigger and stronger every year.

Love this fertilizer, but really hate the packaging. Eventually clumps due to “resealable” bag.

I have used this orchid fertilizer for a whole month now. Great product. I like that it also has magnesium and calcium. I don't have to buy separate and then calculate how much to add. My orchids seem to love it as well. Be sure to check the ph after mixing.

Packaging was good, came in great condition, no spillage, etc. Reason for 4 stars: When feeding my orchids at ~200ppm (in rain water), noticed burnt root tips. Tried 50ppm and still same results. I know lots of ppl use greencare MSU formula with great results but I don't think it's working for my orchids?

I’ve used this fertilizer for years on my Hoyas. It’s a good balance and the plants thrive.
