I planted a Buddleia Blue Chip and it is in a pot in full sun.It is the last resting place for our late departed pussy cat Oscar who loved butterflies.
In the first year it flowered but barely survived the winter.I gave it some tlc including a light prune in April.It seemed to progress well but suddenly the leaves started to go yellow and it looked very thin.I thought it needed a feed so I gave it liquid seaweed and Iron that didn't seem to help.
I have kept it well watered have I over watered ?.It is now looking very sad very thin and very yellow.I am new to this so I will later try to upload a photograph.I know that they love lime so my current thoughts are:-
1/If I do nothing it will die.
2/I propose to remove the top layer of compost, sprinkle some lime, add a layer of new compost.
3/Water in well.
Any comments please.
