How do you make all purpose potting mix?

A standard recipe for a homemade soilless mix consists of half sphagnum peat moss and half perlite or vermiculite . To mix ½ bushel basket or four gallons of media: Start by pouring two gallons of peat moss into the bushel basket. Add two gallons of either perlite or vermiculite and mix thoroughly.

How do you make the perfect soil mix?

A mixture of 70% garden soil and 30% organic matter creates a good general potting mix for planting up trees, shrubs, perennials and fruit. If your garden soil is heavy, reduce the soil content by around 10% and add some sharp sand, grit, or bulky organic matter in its place to improve drainage.

What is the best ratio of potting mix?

NOTES: A simple effective potting mix recipe is to use 75% Peat Moss + 20% Vermiculite + 5% Perlite .

What is the number one potting mix?

We recommend Roots Organics Original Potting Soil as the best potting soil for outdoor plants because it works for all potted plants, from seeds and flowers to trees and vegetables, using enriched nutrients that allow for optimal drainage. One of our favorite features is that the bag is ready-to-grow.

Do I need to add anything to potting mix?

Do you need to add fertilizer? Containers are quickly depleted of nutrients due to regular watering. Even fresh potting mix that contains fertilizer will need supplemental nutrients . Midway through the growing season, apply a water-soluble fertilizer such as fish emulsion or seaweed every two weeks.

What is the ideal soil mixture for plant growth?

The ideal mixture for plant growth is called a loam and has roughly 40% sand, 40% silt and 20% clay. Another important element of soil is its structure, or how the particles are held together - how they clump together into crumbs or clods. A loose structure provides lot of pore spaces for good drainage and root growth.

What is the ratio of soil to solution?

Both the international ISO standard and modern soil classifi cations and databases require soil pH measurement at a 1:5 soil:solution ratio, while the ratio 1:2.5 is still the most commonly used in Poland and other European countries.

What is good quality potting mix?

While the basic peat moss, pine bark and perlite type potting mixes will work fine for almost all annual flowers and mixed potted plants, there are some crops for which specialty mixes might be helpful. The most common is potting mix for orchids.

What is difference between potting soil and potting mix?

It's a common misconception (often the result of confusing branding), but potting mix consists of organic matter and fertilizer along with pearlite or some drainage aid. Potting mix is commonly lighter and has better drainage and aeration than standard potting soil.

Is it cheaper to buy potting mix or make your own?

Initially I believe it might be more expensive but when you factor in an economy of scale (cheaper to make a big batch than a little), the need not to replace seasonally as you would with a inferior mix and the better success of the plants grown in it, I think you wind up ahead of the game dollar-wise.

Can you use all purpose soil for potting?

Soil taken from your yard or a garden bed is too dense to use in a pot or raised bed. Instead, for containers, you'll want to use potting mix (also called potting soil), a lightweight and fluffy alternative . For raised beds, you'll want to use a blend of potting mix and garden soil.

All Purpose Potting Soil Recipe: The Perfect Mix (2024)

The above excerpt is fromThe Community-Scale Permaculture Farmby Josh Trought. It has been adapted for the web.

Annual plants require an early start to bear fruit in the short growing season of New England. The planting medium, daylight length, and temperature conditions are crucial factors for a healthy nursery of seedlings. In an attempt to localize our annual production we start seedlings on-site. This production requires specific timing and appropriate conditions for each species of annual.

A kale transplant, ready for the ground, has been nurtured through the entire process of seeding in the basem*nt, potting up, and hardening off in the Big Cold Frame. The fine root hairs have expanded throughout the soil.

Our indoor seedling nursery is a compromise between our attempts to provide a food system that is expansive and one that is acceptable for the conventional consumer’s palate. We grow many vegetables, such as eggplants and tomatoes, that are not native to this climate and require a longer season to bear fruit. We also invest in indoor operations to extend the growing season and maximize the production of our operations. This investment is substantial in terms of time, energy, and effort.

There are many choices regarding how to grow nursery starts. We have resorted to the standard plastic trays that are common in the nursery industry. The trays provide individual cells so seedlings can be easily transferred for transplanting without root damage. These containers provide a shape into which the soil and root fibers can mold and resist erosion from watering. As an alternative to plastic we have also made newspaper pots by rolling the paper into an origami-shape container. These pots are laborious to construct, though fully functional for seedling production. We also have used large quantities of recycled containers that were originally purposed for yogurt or soy milk. These containers can be functional, though they require substantial drainage holes to be drilled to allow aeration and bottom watering capacity, which encourages healthy plant growth. Round pots can also increase the complexity of the spatial relations in the nursery whereas square pots can stack together in higher volumes. We have also considered purchasing gadgetry to make soil blocks, which would eliminate our need for plastic trays and containers; however, we have resisted this course of action because peat moss or coconut fibers are typically used to retain moisture and the block’s structure in this system. We have been reluctant to add another layer of dependence in sourcing this ingredient material as a component in the process of food system. That said, we will continue to experiment in choosing alternatives incentivized by circ*mstance and ethical inquiry.

To build our soil medium we start by considering the needs of the plant roots. The medium must have the capacity to retain moisture while also being porous and well drained. The medium should have structure to allow the roots to grasp the material and prevent damage during the transplanting phase. This medium also provides a nutrient and energetic boost for the initial growth of the plant.

To create this medium we have developed an all-purpose potting soil recipe. The recipe we are currently using consists of 5 parts loam, 5 parts compost, 1.5 parts vermiculite, 1.5 parts perlite, one cup humates, and a quart of Paul Sachs’s Pro-Start 2-3-3. This mixture allows us to build up the existing soil medium by incorporating portions of the limited supplies of compost and imported soil amendments.

Loam is sourced on-site. The local loam is sandy and well drained, providing a basic building block for our soil fabrication. This material, however, lacks sufficient nutrients, structure, and water retention capacity to maximize the health of seedlings. Consequently, we mix in additional components to improve the medium.

The compost sifter is a homemade tool. The A-frame can be moved to a finished compost pile, and with a wheelbarrow placed below the hanging frame, the sifted material can be wheeled easily to the Big Cold Frame or basem*nt seeding stations.

The compost that we reserve for our potting soil is typically the highest quality that we can attain. It is important to source compost that is nutrient rich and free of weed seeds. The structure of superior compost provides particulate material that helps retain moisture and provide soil structure. We generally sift the compost through a quarter-inch screen so the large indigestible particles are eliminated from the mix that is to be returned to the compost heap.

Sifting compost can be laborious. We use framed screening to sift it through. To augment the process, screens can be suspended by a structure: As the compost swings in the screen, the motion encourages sifting. Other mechanized tumbler structures can provide this filtration process, producing a fine, soft, black, crumbly compost.

Vermiculite and perlite are soil amendments that we currently source from the agri-industrial complex. Vermiculite is organically certified and is created from heating the mineral mica to absurd temperatures. It is relatively inexpensive and compensates for high proportions of loam by providing superior moisture retention and lightening soils as a conditioner. Perlite comes from volcanic glass and reduces compaction by offering high permeability and low water retention.

We also incorporate various soil amendments in our potting soil medium. These amendments are intended to provide energetic components and nutrients that are readily available to plant roots as well as long-term nourishment for the soil food web. The amendments are generally rated by their proportions of nitrogen, phosphorous, and potassium (NPK). While the NPK proportions provide a measure of the amendments’ capacity, this over- simplification of the seedling’s necessities does no service to the reality that the plants require over fifty elemental nutrients for health.
