Is it too cold to grow potatoes @350m above sea level on Mt Taranaki

Should be ok - as long as you harvest before next winter's frosts. Plenty of sun.

I grew potatoes this year for the first time. I planted 12 pots and all I got back was about nine or ten potatoes. I planted mustard over the winter, dug in etc. it was very dry and I didn't water much could this be the problem. I thought if I watered too much they might rot. What did I do wrong? Thanks

Have good loose soil, not too rich in N. Dig a furrow 12 (?)

I've had that happen a couple of times in containers - it seems they like warm conditions but cool roots or they just produce leaf growth. And yes plenty of water - about an inch a week. Soil should be sticky.

That's a big subject! I'd say it depends on what you're trying to achieve. Do you just want a few really good veggies? Do you want to grow as much of your daily food as possible? Does your garden need to be aesthetically pleasing? There are lots of books on container gardening, you could try browsing your local library online. If space is limited, I say think about which veggies you love the most, which are pricey at the store, and which are most improved by eating fresh. Basil and salad greens for instance, are very easy to grow but very overpriced at the store. Corn and tomatoes are so much better homegrown. Whereas potatoes and onions are cheap at the store and not THAT much better homegrown so they're only worth it if you have plenty of space to devote. My advice for a beginner would be to start small and manageable, and build on that each year. Maybe this year buy a couple of Earthboxes or DIY a knockoff, and just grow a few of your favorite veggies. This will also reveal what some of your challenges might be. For instance my first year raccoons ate all my sweet corn, that taught me I would need a good fence in the future. ;-)
