Excellent product
Excellent product. Though the container is very compact, it is so concentrated that it is a very good value for the money. Very easy to use. So far, my orchid seems to be responding well. Works great. No problems.

Great for Jasmine !
Worked perfectly for my Jasmine. I tried it as well for my anthurium and waiting the result. Make sure to wear gloves while using it. I felt some little burn sensation on my skin when I used it without gloves. Make sure to follow the dose instructions.

Easy to use
This product is very good quality for producing great repeat blooms. It’s easy to mix and I use it bi-weekly. Having invested a lot of time and money in my garden I chose this fertilizer after researching several others. Within a few days I noticed good color, new growth and a lot of buds. It doesn’t burn the plants if used as directed. The smaller size will last me at least three months if used as directed.

Does help in blooming
This fertilizer does help with blooming be careful not to mix too strong though, it can be dehydrating.
