MSU Orchid Fertilizer 13-3-15 (Greencare) Reverse Osmosis, Rain, Tap Water Formula. 2 Pounds, Scoop Included

UPDATE 10/9/2025 This is a great fertilizer, BUT I made a mistake and purchased the large bag since I have a lot plants. I guess I didn't use it fast enough as the fertilizer changed colors and gave off a strong chemically smell. I did reorder but got a smaller back. I then decided to switch back to my other do to because I never had to worry about "spoilage". If you buy this in the big bag, make sure you use it quickly, it will not last months if you don't. I absolutely love the neat packaging that is able to seal. Comes with a tiny scoop. If used as suggested, this 2lb bag should go far. The only reason I ordered it is because the formula is made to work with tap water. Never heard that before and watering with tap water has always been a concern. I had one of my Hoyas bloom for the first time since using this.

Wonderful product. Since using it half strength, I’ve seen plant growth and lushness increase. A completely great value for the money. On the first day of using it, I saw a couple plants push out new leaves.

I have seen tons of new growth on my orchids. Most have doubled in size producing multiple pseudobulbs and tons of root growth. I dilute the formula more than the instructions say, since I feed my orchids every other watering so I do not burn any roots. If you were only feeding once a month you may want to keep it at the recommended strength. I then dump the leftover water from my orchids into other tropical plant pots. They love it too.

My Orchids, and a few other plants, LOVE this fertilizer. I have been using for several years and they have done great. Just mix with water and fertilize.

This seems to be a great fertilizer. I definitely have seen a boost in my orchids. I only wish the product wasn't so expensive.

Bought this for my phalaenopsis orchids and they are doing extremely well. They are all growing new leaves and all 3 have grown new spikes less than 1 year from when the old spikes died off. I have one orchid that is naturally growing a keiki as a result of using this, I believe, as I haven't put any other paste or fertilizer on the plant. I use this fertilizer with tap water from the sink, I soak my orchids for 10 min in the solution every week. This bag is going to last me forever! Highly recommend, great value for the amount of fertilizer you get.

Dave The Sober Plant Guy on you tube uses this product for his Hoyas and supplied a link to it. I used it to purchase a bag, and I am very happy that I did. I had no idea there was so much difference in fertilizers. Anyone that is growing Hoyas should use this product.

I have been using this fertilizer with my collection of 30+ orchids for over a year now. They are healthy & reliably bloom.
