Choice of Media Contd...

As written in my earlier post I was little disappointed with cow dung manure and realized that little soil is required, reason mentioned there, I replaced the cow dung manure with the soil. With this amount of soil I can get the benefit of both the world. The media does not form hard cakes. It remains nicely granular, fairly light weight and retains moisture.
Along with this I have tried some soil amending agent. So many soil amendment agents are used. They are mainly used to aerate  the soil. They are Perlite, a volcanic amorphous material has water retaining capacity. These granules are extremely light weight.  vermiculite, a hydrous polysilicate material serves the same purpose. Coarse sand also aerate soil and facilitates drainage.
Perlite and vermiculite are relatively costly. I used in some containers , but did not find any difference with those where I didn't add, so now I don't use that. I, of course use sand in those plants, who does not like wet feet, like papaya. Another amender I use is Neem cake dust. Neem has some nutritional value and keep the pests at bay.
Regarding source of the cocopeat , Kolkata is not a good place. Many nurseries has not yet heard about this, so no question of selling.

  1. How do you reuse the media in the containers after a season is done? I have so much cocopeat + compost mix from the winter's tomatoes, etc but it is full of roots, and I am not sure what to do to it before reusing it.

    1. I usually keep the roots, unless they are very thick trunk root. I add compost at the end of season and use the same media. The roots will ultimately decompose and add nutrition to the media.
