Kia Ora
We have a palish blue wisteria planted about 10 years ago.
We have to trim it back severely every year, it produces a few sparse flowers
for a short time then heaps of luxuriant green.
I have looked up Google & it says that feeding should be restricted for good
flowering. We have never fed the plants.
Any suggestions for getting rid of excess nourishment please.
The plants are in the garden, not in pots.
I know we are in NZ, but please help
Thanks
Mac
