Southeast Soils is a custom blending facility for professional potting media. We source over 20 components along with numerous fertilizers and additives to create countless blends of soil-less substrates.

MEDIA COMPONENTS

Pictured are our more common components but we carry other specialty products such as expanded shale, clay, DOT sand, well point sand and more.

Ferti-comp®
Ferti-comp® is a unique product derived from a proprietary composting process developed by our partners at Harvest Quest.  Mature, stabilized ‘Class AA’ compost is produced using a bacterial catalyst which enhances the natural biological process of composting. The end result is a product that has been shown to contain vastly increased numbers of beneficial bacteria when compared to those produced using traditional composting methods. These beneficial bacteria help with disease suppression and nutrient retention and Ferti-comp® provides organic forms of several nutrients. Ferti-comp® is used as a soil additive and a media component. It can be used in place of Florida peat and can improve all types of media mixes. We have multiple sizes for different applications.

Florida Peat

A widely used media component, peat is mined throughout Florida. It is formed from decaying plant material at the rate of about 6” per 100 years. Only high quality, fibrous peat should be used in containers. Florida peat has some water and nutrient holding capacity.

Florida Peat “A”

Florida Peat A is a blend of our native Florida peat and Ferti-comp® that provides benefits of both products. It contains beneficial microbes and a higher nutrient holding capacity than regular peat and is commonly used in place of straight peat. Using Florida Peat A is a ‘greener’ choice than straight peat in that is cuts down on peat use, which is considered a nonrenewable resource.

Sphagnum Peat
Sphagnum peat is a common component of greenhouse and propagation mixes. It has a high water and nutrient holding capacity and good aeration. We have multiple sizes and use only quality sphagnum peat from Canada and Europe.

Coir-Coconut Fiber

Coir fiber is a great alternative to sphagnum peat and is a non-restricted component. It has excellent water holding capacity AND excellent aeration and performs great in all types of mixes. All our coir is washed to reduce salts.

Nutri-Bark®

Nutri-Bark® is a partially composted pine bark made in house with 3/8” pine bark. It has a lower carbon-nitrogen ratio than 3/8” green bark, i.e. less nitrogen loss to microbes. A great alternative to perlite, Nutri-Bark® has a higher water holding capacity and excellent drainage and will provide some beneficial microbes and nutrients.

  Pine Bark 1/2”

  Pine Bark 1”
In terms of quantity, pine bark is probably the most used potting media component in the Southeastern United States. Used to provide aeration to a mix, we offer numerous sizes (more than pictured) to suit different size containers.

  Pine Bark 1 ½”

 Cypress Dust
Cypress dust makes a great component for propagation mixes and other lightweight mixes. It will hold some water but also provide air space for roots to easily penetrate. As a sawdust, it will tie up some nitrogen. Cypress wood naturally resists decay more than many tree species and has a higher pH than our other wood products.

Cypress Fines
As cypress wood naturally resists decay more than many tree species, cypress fines are used for aeration in mixes where longevity is a concern. Cypress fines have a higher pH than pine bark.

Hardwood Fines
Also used to provide aeration to a mix, hardwood fines are a more cost-effective alternative to pine bark. With a pH slightly higher than pine bark, our hardwood fines consist of the inner wood of the tree.

Perlite
Perlite is heated and expanded ore. A common component in propagation and greenhouse mixes, perlite provides excellent drainage in small textured mixes. Perlite will not breakdown in a mix.

Vermiculite
Vermiculite is heated and expanded mica. A costly mix component, vermiculite is typically used in smaller amounts in germination and propagation mixes for its high nutrient holding capacity, low bulk density, and water retention capabilities.
