Just half a teaspoon under the strawberries during flowering! The berry is large and sweet 

I cut up banana skins, leave them to stand for 2-4 days. 2 skins in a litre of water. Use about 10% of this to (rain) water when watering. I’m going to retry this this year! Will let you know the results?! Plus have flowers near the strawbs for pollination?…

It would help if you showed the brand or what it would look like on the bag.

The ganular potassium humate . I have does not desolve I have tried letting set in water it does not break down even after weeks setting in a jar of water

Did I understand you correctly? I am to apply this one time only at flowering. No other fertilizers needed.

Where i can find the pottasium and which brand

Such a shame that you don't let us know what brand you use and/or link it here.

Why not use a dried banana peal?

Doesn't seem you can get this potassium in the Netherlands... :( Any alternative?

Where did you get it?

Thanks very much

will try this ... thank you

Do strawberry yields decrease as the plants get older?

All the ingredients sound like the stuff in ev batteries.

Schade ich hätte das ganz in deutscher Sprache verstanden
