Fertiliser tubes

I was thinking how to eliminate/reduce the debrits left in the substrate after using Biogold.   Not very happy with the frequently used tea bags.   I think that while this application fix the problem with debrits the cakes dissolve extremely slowly ( I may be doing something badly though... )

I have been using tubes to hold the fert in the position for some time - again this is something widely used.   Last year I have made few adjustments to reduce the "contamination" of substrate with debrits.  

The bottom of the tube is covered with the synthetic gauze.  Inside the tube there is a bottom layer of sphagnum moss then few pellets of biogold and another layer of sphagnum moss.   Thats it.

The first layer of moss prevents debrits to get into the soil and also keeps the inner part = pellets moist.  The top layer of moss helps to keep the humidity on  approriate level most of the time ( at least for my watering frequency ).   Standard watering provides the plant with a reasonable supply of fert.  And if I need to push it more then I use 5 l sprayer can and flush the water directly via tubes.

Last year I have used a lid to cover the top  ( another piece of mesh - this time a piece of plastics ) to keep the blackbirds away. Not using it anymore now - the population of blackbirds has been reduced dramatically last year due to the infection.

Great idea. Thanks for sharing!

Vlad,

I really like this idea, and I think will test it with a type of
osmocote that comes from Israel, and is designed for
30 deg.c weather.

We already repair the sieves by melting the mess into the
plastic, so your idea could be evolved to small pvc pipes
and stainless steel mesh.
Thank You !!!!

I will offer this -

When a soil is made up totally of inorganics - think hydroponics.
When you add the fermented oil seed as cakes, they compost
and add an organic into the soil miix.
This allows for microbes from the compost and improves
the plant's health.

Think traditional growing in the earth and applied left over plant parts
from a harvest.

I am not sure with teabags as you get NPK plus micro-nutrients.
But no compost.
Like a chemical fertiliser e.g. Miracle - Gro
Maybe, the dust and dead insects/ bird poop are enough to full
fill the microbe factor/ need ?
Until.

Khainraj, using the stainless mesh is a good improvement

I am testing the inorganic substrate just for few trees to see if it can work for me.

Right now most of the tubes are on some of my trees that I do not transplant very often.

Excellent idea. Thanks for sharing, Vlad.

@Lost2301 &  Alain,  thank you very much. Happy you like it, guys
