live in Whangarei and plant my potatoes about early Oct. I have
been disappointed with the crop I have got of the plants so far.
This year I used a seed potato Ilam Hardy with plenty of sheep manure
and blood & bone. My soil is mainly volcanic. Can you please
make any ideas for a better crop? Or is the wettish weather a factor?
sounds like you are doing everything basically right. However, I
do wonder if you are waiting long enough to get a decent crop. Ilam
Hardy is usually harvested in late summer rather than in December.
If you want potatoes for Christmas (certainly a reasonable desire
in my book), then I suggest choosing a different, earlier cultivar.
Usually with potatoes, it is best to wait until the foliage has
died down to get the best yield. Chances are that if the foliage
is growing vigorously, it is doing so to feed the tubers below ground.
Potatoes are very sensitive
to soil moisture levels. The wet weather should have kept things
moist, but did they dry out at all? Lack of water during a dry spell
can reduce the size and number of tubers you get.
You could also try an
occasional foliar application of an appropriate fertiliser.
