Organic pellets - fertilising

[Krone]

This year i'll have much more trees in growing boxes, so for this trees i will abandon fertilising with the help of tea bags (i use organic fertiliser, pellets).

If i put the fresh pellets on the top pf the substrate every two weeks, should i remove the old, decomposing one to prevent over-fertilising or can i just leave it and simply add the fresh one?

Should i maybe wait for the old pellets to almost completely decompose before adding the fresh pellets?

Thanks!

I just add new pellets every 3-4 weeks. 2 weeks is pretty quick as the pellets are sort of slow release but maybe that depends on the type of pellets. How many and how often will depend a lot on the type and size of tree, type of soil, weather and time of year, makeup of the pellets and what stage the tree is up to. There are so many variables it is hard to give definite numbers. You will probably need to try out some different regimes and see what works for you and your trees.

Scrape off old decayed fert once or twice a year if necessary. Most of what is left gets scraped out at repotting time. It is not so important to remove old fert from grow boxes as it is in smaller bonsai pots where excess can clog up the soil in a small pot.

It is difficult to overfertilise with organic pellets as they generally have quite low nutrient levels.

I’m not in your climate. However, I use a small pellet ball type fertilizer. Granular is what it’s called. All purpose. Works for me. I like that it continually breaks down to fertilize with any watering or rainfall. After a couple months....I simply add new as if I was starting all over. I’ve not encountered any problems....possibly because the dissolve rate is slow. The old pellets are probably quite weak by the time I’m adding more. With an application of pellets I don’t overdo the amount applied. I tend to fertilize on the weaker side actually. I started using this about four years ago.

I have been using these for the past year and they seem to work great, just bury them in the soil an forget about it.

I have pelletized cow dung that I use.
It breaks down fast when wet, and it falls apart to dust. It cakes up the soil pretty fast, give or take two summers.

So I switched to using air-pot bags. Kind of like tea bags, but these don't break down. I made the mistake or ordering way too small ones for seedlings, so I have roughly 200 to spare.
They hold up pretty well too!

I tried scraping the top layer but the manure just sinks down. At the end of winter, the top layer is practically clean of debris and the pellets are somewhere in the middle or the bottom of the pot.
