This is exactly what I needed to change the PH of garden. We had a Blueberry garden that we need for some other veggies. A good sprinkle of lime and the PH was coming up, just a little more and then we were getting places. 👍✌️

Exactly what I was searching for!

Thank you for all the precise information so I could choose exactly what my babies need.
Have just ordered succulent mix - due any day. Maybe I will not have so many wither and die as I did last year. Even my Buddha's Temple. Thank you so much, Janet

Gnats be gone!

I rarely get gnats as I bottom water all of my plants, however I needed to repot a couple of plants that had outgrown the pots they were in. I purchased a good branded potting soil and the gnats came from that bag. I was out of Tanlin Drops and needed to order a bottle. Within a couple of weeks, they were gone. I have gone through all of the old wives tales and nothing beats these Drops.
Those pesky little gnats are gone!
