CULTIVATION OF NATIVE FERNS

The cultivation of ferns to enhance the landscape

Ferns need only 4 inches of good organic soil to develop.

Light, fresh, organic-type soil such as forest compost is essential for planting.

It is composed of aged composted bark and peat moss.

The acidification of the soil with elemental sulphur allows for faster adaptation and growth in our environment.

Ferns need acidic soil with a pH level of 5 to 6. to be able to absorb the nutrients necessary for their growth.

Elemental sulphur remains the most economical way to lower the pH of low-acid soils. However, its effectiveness is based on the following factors:

  • the inclusion of sulphur in the soil;
  • the presence of an active population of sulphur bacteria. These bacteria convert sulphur into sulphate (SO42-). It is this conversion that acidifies the soil. Most soils contain this bacterium
  • time (plan ahead). Acidification is slow. It will take three to twelve months depending on the soil temperature and humidity level.

At the planting stage

Add elemental sulphur to the planting mix at a rate of 1 kg per cubic metre

1 kg per cubic meter reduces the ph from 0.4 to 0.7.

So if your ph is neutral, i. e. 7 ph, you lower it by 2 to have a ph of 5 for ferns.

So 3 kg of elemental sulphur per cubic metre of substrate.

Existing plant-growing area

In an existing plant-growing area, dispersed with a manual seed spreader, granular elemental sulphur at a rate of 1 to 2 kg per 100 square metres 2 kg no more. 4 lbs. per 1000 square meters.

Elemental sulphur can be obtained in most garden centres or agricultural coops.

MAIN CAUSE OF POOR GROWTH OR MORTALITY

Compact soil: You should be able to plant a pencil easily in the ground without much effort.

An alkaline Ph: The more acidic the soil, the more nutrients the fern can assimilate.

A crown too far out: Ferns feed by their lateral roots, so if the crown is too far out of the ground, it cannot develop its roots and feed itself.

A crown planted too hollow: The sticks are already rotting and withering is inevitable within a year.

Planting distance for laterally developing ferns species (ground cover)

These recommendations are for the most efficient planting with the goal of almost complete closure in the second year. You can reduce the number of pots according to your budget or requirements.

This fern landscaping was created by our horticultural team in August 2017 on a 120 square meter leaching field. The land is rather dry and sunny for 6 hours a day.

Check out the design steps at the bottom

The layout consists of a beech fern colony (thelypteris phegopteris), an excellent cover for wet or dry ground.

The planting rate is 11 ferns per square meter

The format used is the M-32 pot of 270 ML

A year later, the ferns reached a diameter of 16 inches. Note that the summer of 2018 was extremely dry and that the plantation has no irrigation system.

3 inches of light soil has been added to the existing ground. This species of ferns are more resistant to mineral soils than other ferns.

The addition of elemental sulphur has been crucial in the development of ferns. Where there was no sulphur, ferns showed very marked reduced growth and nutrient deficiency.

The addition of bark mulch is essential to maintain the soil and keep moisture on the soil. The decomposition of this mulch will enrich the soil with humic acid, which is beneficial for the ferns.
