Bringing Nature Back to Your Garden

We’ve said it before, and we’ll say it again – gardening doesn’t have to be difficult. In fact, it should come naturally, which is why we created Mammoth Garden® products – to give every gardener, from the grandmasters to the greenhorns, the edge they need to grow better, more beautiful gardens. All of this with the power of nature and science in a bottle. From fermented alfalfa filtrates for enhanced plant growth to plant-derived biocontrol products for natural prevention and control of pests, Mammoth Garden has the answers.

The Questions

We know you want to grow the healthiest garden you can, so we wanted to give you confidence in a product that has natural origins and still gives your garden the powerful effects that you need. When it comes down to it, you want the answer to two questions:

How do I start my garden?

Starting a garden, or even adding plants to an existing one, can be tricky. What’s the best way to get your plants on the right foot? Does this step really make a difference? (It does!)

How do I grow a better garden?

Nature has everything you need to grow the best garden you can. Most of the time, all of those forces don’t meet all your garden’s needs. Your garden may be gorgeous, but is it living up to its full potential?

How do I protect my garden?

You’ve put in the time and money – it’s only natural to want to defend your garden from pests and disease. But why do the usual suspects have to be so harsh? There’s got to be a better, natural way.
