Colonizer is a blend of diatomaceous earth and highly concentrated beneficial bacteria that can actively colonize growing media and plant roots while significantly reducing water requirements.
Diatomaceous earth which makes up the bulk of this product improves soil structure, provides aeration, and balances water
and oxygen levels in the soil. The added oxygen helps stimulate the biological activity in the soil, providing for significantly improved root growth and nutrient uptake.
Colonizer provides much of what is essential for successful organic and natural horticulture.
Colonizer Plus is Colonizer with an added blend of twelve types of 
proven mychorrizal endo and ecto spores which essentially extend the reach of roots deep into the soil strata. Our mychorrizal blend has been proven effective for the widest
possible range of plant species.
When should I use Colonizer?
Every time you plant or transplant.
Every time you prepare a soil or garden area for planting.
In soil premixes for both ground and potting applications.
Employing Colonizer or Colonizer Plus in your gardening program is a vital step toward responsible environmental stewardship as it will help reduce water usage and
reduce required fertilizer applications. Additionally you will enjoy the dramatically healthier plantings that will result.
Why should I use Colonizer? Sterile potting soil, overworked soil, drought and disease affected soils and recent construction sites are most often devoid of important humus producing micro-flora.
Additionally, root diseases most commonly occur when transplanting but can also develop from over-watering or environmental stress.
