EM-1 helps plants in so many different ways. From organic gardening to transplant health and just to give your soil a boost in microbial activity. I have been using it for years and all of my plants are thriving, even my 10 year old houseplants continue putting out new growth. EM-1 is great stuff.

Thu, 10-15-2026. Inoculated-charged my 1 cu ft of biochar with EM-1, along with other stuff. Mixture is in 5 to 6 month brewing-steeping stage; after which, I will apply to base of plants in my garden. Wish me luck.

This microbial support is critical for our soil.

I love this product on my 50 year old avocado tree and it loves it , my tree produces like a young tree. it is worth it.

Great stuff

This product works very well on pet urine

Works for me

Someone complained about small bottle? Well if you use 3oz per 1/2 gallon that gives you 5.3 batches and you only use 1.5 oz per gallon of that , so that is quite a bit ,unless your on a farm, it’s hard to tell how good it is when you add it to your weekly fertilizer schedule, veggies are thriving tho

Soil health

Like a probiotic for soil it boosts plant health!

Works wonders on all plants

EM-1 really does what it says. We have had so much excellent results with using it on vegetable plants, flowers, and even trees.You will not regret it when you try it.
