Lawn fertilizer for maples

Hi all

I found an organic lawn fertilizer in my nursery but of course the instructions are for square meters.
Does any of you have an idea of how many teaspoons I should pour into my 10 liter watering can ?

Thanks and happy new year from France,

Fabrice.

 

Should be applied during the warm time of the year, giving you months to identify a conversion.

First, if it's organic, the risk of burning the roots by over-fetilizing your trees is limited.

Second, there are many organic fertilizers available in tree nurseries, why lawn fertilizers ?

I'm sure you can find "Or Brun" for instance, it's mainly composted manure (12-14 months) and algae:

Less ubiquitous, Solabiol have very good products too. They have an interactive map where you can find local dealers :

I had thought of lawn fert for it was described as close to perfect NPK ratio for maples.
Anyhow I have found today an organic fert for conifer with an almost similar NPK ratio.
AND it has the proper instructions for use.

Thanks a lot to you all
I intend to change all container soils for Al's gritty mix next spring.
