Detailed Potting Soil Information

Baby Bu potting soil is the gateway to more nutrient dense produce from your garden. Baby Bu biodynamic potting soil is designed for containers and raised beds. It’s unique formulation of Coco Coir, Malibu Compost (the finest biodynamic compost on the market), Composted Bark, perlite (which won’t breakdown and need to be replaced like rice hulls), and our custom blend of diverse organic fertilizers, establishes a rich and balanced medium in which to grow your garden.

Coco Coir (coconut husk fiber) is a rapidly renewable byproduct of the food industry. To create a usable medium for gardening, the husks of the coconuts are stripped away, pounded and separated into grades, then it is washed and aged. Coco coir has a unique structure that enhances a gardener’s ability to maintain a proper ratio of air to water in the root zone (porosity approx. 90%, air space approx. 10%, moisture approx. 75%). Coco coir also has a very high Cation Exchange Capacity, which is essentially the media’s ability to hold on to and exchange the nutrients plants need. When Coir dries it does not shrink like peat, nor does it repel water as throughly, making it a much more user friendly media in container gardens.

When Coco Coir is combined with the amazing properties of Malibu Compost, it becomes a super soil containing all the wonderful microbes and fungi found in our compost. These beneficial microbes are the true gardeners in our soil. We give them a happy place to live and grow in symbiosis with your plant’s roots. We give these microbes soil with ample water holding capacity (thanks to the Coir, Compost, and Fir bark) yet balanced with a sufficient supply of air to keep them aerobic and humming along (Thanks also to the Coir, and a touch of perlite). To top it off we give them friends (the beneficial microbes in worm castings) and a veritable smorgasbord to feast upon.

The custom blend of organic fertilizers has been carefully selected to create a balanced diet for the microbes, and therefore your plants. We use two sources of fish fertilizer, one of the most ancient human applied plant foods. The fish meal and fish bone meal act in conjunction to provide ample amounts of nitrogen and phosphorous, which both contain amnio acids and the building blocks of DNA and RNA. Additionally, the organic soybean meal ( we use certified non-GMO sourced) contains ample carbon and is an excellent source of nitrogen, with a compliment of phosphorous and potassium. Soy is also a great source of amino acids, which our microbe friends love. Alfalfa meal is another nice source of nitrogen, which we also use in our soil to boost protozoa numbers (they tend to hang out on Alfalfa). Alfalfa has a natural amino acid “growth hormone” called triacontanol, which is useful when plants start to establish a healthy root zone and vigorous growth. Triacontanol is the “secret ingredient” to several popular commercial chemical fertilizers on the market, but here we get it in it’s natural form - organic and right out in the open. Alfalfa meal also has a nice compliment of micro nutrients that also feed our microbe pals.

Bat Guano, another ancient fertilizer (plant food of the Inca) provides nitrogen, phosphorous and potassium, as well as slow the release of calcium. Guano is also said to aid in the flavor of fruits and veggies it helps to grow. Oyster Shell is a wonderful source of Calcium, which is a very necessary element as it is the key component to plant cell walls. Calcium deficiency is the main cause of blossom end rot in tomatoes.

We use Crab meal to bolster our quicker release nitrogen and phosphorous sources as it is a much slower released source. The crab meal is also a wonderful source for chitin, which is the basic component of the crab’s shell (and exoskeletons of bugs too). Chitin is a great food source for our microbes, mainly our Fungi friends (as it is the main component in their cell walls).

Neem Seed meal is a helpful addition to our soil, because not only does it provide a boost of nitrogen, phosphorous and potassium, it also stimulates microbial growth and acts as a mild insect discourager.

A subtle use of Rock Phosphate is used to boost the Phosphorous, Calcium, and a touch of iron. It acts as a balancing platform for the soil’s natural Ph fluctuations. Langbeinite is another name for a Potassium Magnesium Sulfite crystal, which balances out our Nitrogen and Phosphorous and adds a boost of micronutrients too. Potassium is key to the plants ability to move carbon dioxide and water, and it also acts as a enzymatic regulator in the plant. Magnesium is essential for photosynthesis. Sulfur is a key component to amino acids and your plant’s metabolism. These also play a role in the overall flavor and smell of your fruits and veggies. Green Sand is Iron Potassium Silicate, which are essential minerals for plant growth and microbe health. It is a slower release source for long lasting soil health.

We incorporate Volcanic Basalt to boost calcium, magnesium, iron, manganese, and add a touch of silicon, copper, zinc, boron, and aluminum.

Our final component to round out the feast is our dessert, Kelp meal. It may not sound appetizing to you and me, but our microbes love it. Kelp contains a compliment of delicious vitamins, enzymes, and over 70 minerals, all of which are useful to our microbe feast. Kelp also contains natural growth hormones (axuins, gibberellins, and cytokinins) which all aid in your plants reaching their full potential.
