Homemade conifer grow mediums
Homemade grow medium in your pots doesn’t have to be a laborious activity, therefore this might be more enjoyable if the nutrients in the medium could last more than 2 years.
After doing some research, I came across a conifer bark-based medium mix that will last up to 3 years.
5:1:1 mix of pine bark:humus:perlite
Humus based mediums
Humus based soils break down quickly – within a single growing season. When you use them, you have to hope the container size and plant mass is enough to compensate for the collapse toward the end of summer. Hopefully, your roots have spread throughout the container and the planting has matured. This will show that the plant is able to use the water from compacted soils quickly enough to avoid root rot. Rootings should be healthy enough that they actually become a part of the structure of the soil and function as aids to the soils ability to hold air. For maximum vitality when using these soils, plants should be bare-rooted every year.
It is possible to use peat, but harvesting it has been outlawed due to a near extinction. I don’t recommend using it, since it takes millions of years for the Earth to create this delicate material in the peat bogs and just a few years to run it toward extinction.
Conifer bark-based mediums
Homemade conifer bark-based mediums break down at a rate around 1/4 that of humus soils. Gardeners can guarantee that the roots will become a part of the soil structure without much concern for root rot. This will ensure that your irrigation practices are reasonable. 5:1:1 mix of pine bark:humus:perlite is a good example of this type of medium. People using it with very good results. In terms of fertilizing the medium, there is literally no need to add fertilizer to this mix. Perlite and humus may contain a small amounts of fertilizer, so researching your ingredients to see find fertilizer is a good practice.
You should expect at least 2 years of service from homemade soils, as opposed to 1 from those based on humus. Your trees should have some attention paid to their roots every two(2) years – 3 years maximum. “Servicing” requires you to prune the roots. You will be able to prune your roots twice (once every 2 years) with this type of medium.
