Hello,

I have some potatoes growing in pots. At the moment they seem to be
doing very well. They are in compost and as they have grown I have
added more compost to "earth up" and now the compost is at the top of
the pot.

I have been allowing the rain to water them and I have watered when we
have had dry spells but do I need to be doing anything else? With them
being in a confined space, will I have to fertilise?

If so what should I use and when should I use it?

It's been quite a few years since I grew potatoes so do I need to do
anything else? One or two are flowering: do I need to remove the
flower or can I leave them alone?

How will I know when they are ready to harvest?

Thanks in advance!
