The Good Stuff

Even with the built-in shipping cost, this is the best price I’ve seen for the small Dyna-Gro 8 oz bottle. (Then again, I live in Boston, where everything is more expensive haha.) Plus, I’d much rather support you guys at Violet Barn than order the same over-priced supplies off of Amazon.

Good fertilizer

I like Dyna-Gro because it contains no urea. My african violet are very healthy and blooming. Highly recommended!!!

Really good fertilizer

I don't have a ton of experience with using fertilizer but this really works well and is easy to use. It always shows good results and in my experiences has good parts of everything a good fertilizer should have; nitrogen, phosphorus, potassium.

Good fertilizer

I use this fertilizer on most of my house plants. They seem to really like it and makes a huge change compared to not fertilizing. I never fertilized my plants until I tried this stuff someone recommended me. 10/10!

Reliably good fertilizer

Keeps my plants happy and blooming :) I'm following the "weekly, weakly" fertilizer routine and it works great!

I am fairly new to African violet care and cultivation. But not new to using Dyna-Grow. I have used this stuff for decades in the care of indoor tropicals in hotels, recusants, offices, malls, etc. This stuff is G-G-g-g-r-e-a-t!!! Used sparingly and regularly, your plants will always look Fantastic!!!

Great fertalizer

Ordered this with several plants, loved it. They all are growing well and blooming. Will be ordering more when I run out.

Love it

I've been using this on my new plants that I purchased from VB and it's amazing now fast they grow, how healthy the plants are and how many blooms I'm getting.

Great Fertilizer....

As another reviewer stated, this is my second order for this fertilizer...I cannot find it locally..I live in a small town. I can find other products locally, but I have had such great success that I will use no other. It makes good sense to use the same product the successful grower uses...no point in wasting time experimenting....IMHO....

best fertilizer ever

I use this whenever I water my plants. Keeps them blooming for longer periods and the foliage is very healthy. No fertilizer 'burn'

I got some of of this from a friend and now I'm ordering my own . My AVs do great with it!

LiquidGrow Fertilizer

I used the Liquid Grow for a long time. Then I ran out and purchased a bottle of fertilizer at a home improvement store. My violets have never been the same. With Liquid Grow, my violets are in constant bloom. In my mind, there isn't another fertilizer .

My violets thrive with this!

This is my second container of this fertilizer. My violets really do well and I use it on all of my plants every time I water. It is so easy to do it that way and my violets finish a blooming cycle and before I know it, I see buds again. They really do well. I recommend@
