I’m transplanting mint from one pot to another . Do I have to change the whole compost from first pot ( that is more suitable for a holly tree ) before I can plant the holly tree in it ? I am thinking of underground root system of the mint .
I would. My experience of growing mint in pots is that the pot will likely be absolutely full of mint root anyway and very little compost left. If it's only been there a short time and there is still some compost and you want to reuse it, you'll need to sift it carefully or you'll have holly and mint and the mint will always win.
