I use Optimera and Peter's Specialty (no urea), and alternate. between the two.

Superthrive isn't a fertilizer itself, it's to be used WITH fertilizer, makes it more potent. It's like a miracle chemical, noticeably making your plants more robust.

I have been using a drop of superthrive per gallon of water along with my 1/4 teaspoon of fertilizer.

Some of my AV have started to get tight crowns and the leaves appear to be deformed and hard. Could this be because of the Superthrive?

Thanks

I've started using Shultz African Violet plus-nothing fancy. 7 drops per qt. of water. They have all developed buds and are about to bloom, and the foliage is a lot nicer.

Superthrive will cause tight centers.. I only use it now to revive a leaf or plant in stress.. it is great for that. Use fertilizer at 1/2 of what is recommended.. or you could be tight centers from that.. I will not use anything that has UREA in it. I did some testing a while back and discovered, fertilizers that have urea caused more tight centers that the non-urea. Plants were grown under the same conditions.. same variety.

I am sure others will differ, but this is what I discovered thru experiments.

My violets have tight centers, but I like the way they look so I don't mind.

Superthrive is nothing more than vitamin B and a rooting hormone. Nothing more. Ortho makes something identical to it in chemistry and concentration for much less.

My violet centers are tightening up. I'm going to continue with my regimen, let nature take her course, and see how they do later as the temps warm up.

Try Dyna-Grow.

Most any fertilizer is "good". But the best for your plant should have little or no urea in it since this does not allow plants to take up nutrients.

Start with a good all-round fertilizer that will feed foliage, roots and give good health to your plants, Peter's 20-20-20, then two months later switch to 15-30-15 Peters or other brand.
