Great Big Plants Natural Compost Extract is specially designed to improve the health and performance of both plant and soil.

With regular treatments of our foolproof proprietary blend your plants will produce bigger, tastier, and more plentiful fruits and veggies along with vibrant flowers, lush lawns, and full trees- with minimal effort from you!

Great Big Plants delivers benefits through several unique mechanisms.

Your soil works best when it contains living microbes which perform vital functions for your plants roots and ability to take in nutrition.

Great Big Plants contains a proprietary blend of carefully selected beneficial microbes in order to maximize the synergy between your plants roots and the soil. These work to convert nutrients that are otherwise ‘locked’ in a form your plant can’t access, into a readily available food source. Included is a specially designed fermented biotic to boost these microbe populations throughout your plants life.

In addition to thriving soil ecology, Great Big Plants includes humic acids, seaweed extract, and several micronutrients and minerals that are often left out of traditional N-P-K fertilizers. This adresses and solves the ‘Law of the Minimum’ which states that your plant growth is limited by it’s least available nutrient. Great Big Plants fills in these nutritional gaps and ensures maximized growth potential.

“This stuff helped my plants go from almost nothing after a month of growing to roughly twice as big three days after the first time I applied this!”


Vista, Ca

“All my plants love this liquid plant food. My roses bloom bigger, more vibrant and better than before. Their stems are thicker and stronger. The leaves are a much darker green than before. I have some bushes that weren’t growing very well. After feeding them Great Big Plants all last spring, summer and fall they truly are great big plants now. I highly recommend Great Big Plants to everyone.”

"This product delivers everything promised and more!"

“I was given a sample container of this that my son got in the mail. Wow! After using that up, I ordered a gallon for the garden. I am an avid gardener, with big gardens every year. I never want to be without some of this for the veggies again!”


“Buy the bigger jug because your plants will love this!  I first purchased the smaller bottle of this product to see what it would do with my new plants and almost all of them did well with this so bought this bigger jug. I like that it is easy to mix and being a liquid it is absorbed more readily by the plants.”



“We tried it on the tomatoes, chilis, lemon and palm trees and the results were excellent!”
