Mycorrhiza and soil ecology

Mycorrhiza are beneficial fungi that enable the plant to extract nutrients (particularly) phosphates from the soil better than they can on their own. We offer various ways of introducing these to your plants and soil so that you can achieve the significant (15% or so) boost in productivity that they can deliver. We can offer Mycorrhiza as an inoculant for/containerised flowers, shrubs and trees. It also is suitable to make sure that bulbs, potato tubers and seeds get off to a good start.  You can use Mycorrhiza  to.

  • Inoculate emerging shoots  to increase growth and improve plant health.
  • Increase quantity of flowering
  • Increase yields of vegetables and fruit trees.
  • Extend growing season as plants mature earlier
  • Reduce water, fungicide and fertiliser needed for healthy plants
  • Reduces transplant losses

We supply mycorrhizae from Symbio in various powdered formats.

Containerised plants – Dust  1 tablespoon (6gms) per 2 litres of root ball and 1 teaspoon 3gms for every 1 litre increase in size. Ensure the powder covers the feeder roots.

Bare root plants – Put 2 tablespoons (12 gms) into the planting pit so it touches the roots when planted

Hanging baskets  – Dust 1 teaspoon 3gms around the root of each plant in the basket or mix

Flower and vegetable seeds – Add 1 tablespoon 6gms per meter of seed drill or for lager seeds put a pinch of Mycorrhizal Transplanter into the planting hole.

Grass Seed – Mix 100gms with enough seed to cover 100 sq.m and sow in the usual way.

Please note that Mycorrhizal fungi do not associate with brassicas e.g. cabbages or ericoidal plants e.g. rhododendrons or heathers

Mycorrhiza are the beneficial fungi that live in the soil. They form a symbiotic association with the plant – this means its beneficial two ways. The fungi get access to the carbohydrate that the plant synthesises while the Mycorrhizae make minerals – particularly phosphates which are tightly bound in the soil – available to the plants rooting system.

The truth is that the fungal hyphae are much more efficient at releasing these plant nutrients from the soil particles to which they are bound than the plant’s own roots are.

The two organisms interact in two main ways. Some Mycorrhizal strains will actually penetrate the plant’s roots while other strains will form a sheath around the plant root so that exchange of nutrients can occur. This means that in the natural state, far from being individual plants competing against one another, the root systems of plants are actually connected via the Mycorrhizal mass in the soil.

So the main benefits to the plant are as follows.

¤      Mycorrhizae infect the new roots, providing more nutrients, trace elements and water for the plant.

¤      The mycorrhizae and bacteria form a barrier round the root system to help block pathogenic fungi

¤      The healthy plant with access to more nutrient grows faster and yields more fruit, vegetables and flowers.

¤      The healthy plant is less susceptible to water stress and drought

Details of material supplied.

The Mycorrhiza are supplied mixed with a bulking agent e.g. NPK 5.4.3  = soil association approved chicken manure, or zeolite or a mix of both.

The product contains a mixture of strains which cover the different requirements of different sorts of plant.

Endo Mycorrhizae – the strains where the root is penetrated.

Ecto Mycorrhizae – the strains that form a root sheath.

Rhizo Bacteria to solubilise phosphate

Fungi needed to start food web for perennial plants

1 kg treats 166 2-3 litre rootballs

We offer the product  in 300 gm packs which is about enough for a large garden or allotment for a year or in packs of  60gms which is enough for 10 containers or hanging baskets
