You certainly can grow potatoes without chemical sprays and fertilisers. Potaoes have been grown for hundreds of years without them. The soil needs to be friable or cultivated to at least 200mm (8") deep and have old manure worked into it. Plant the potato pieces about the same depth in the soil then cover. This depth is to reduce the chance of potato moths getting to the tubers to lay eggs. As the potato shoots emerge hill up around the stems with more soil or mulch and keep them watered. Potatoes are generally pest free and rewarding and a few can be scratched out about a month after flowering with the remainder harvested when the tops die off. Store the potatoes inside or in an airy, insect-proof container away from light. All the best with your potato growing!

I stayed in Sweden for a few months and was surprised that they ate raw potato in the salads. So potatoes can be eaten raw.

Hello Nixiwaka, yours is a good question! Potatoes can be eaten raw but are safer cooked. Potatoes produce alkaloids which can be toxic. As with other members of the solanum family (tomatoes, capsicum, eggplant, nightshade, etc) most of this is in the stems and leaves. When green patches occur on potatoes it is an indicator that photosynthesis is occuring and these alkaloids are being produced in the tuber. That is why it is important to remove any green part of the potato before cooking and eating them. Raw potato is not easily digested in our gastrointestinal tract and may still be undigested when it gets to the large intestine causing colic cramps or diaorrhea as it ferments. I'll let you decide!

Yes it encourages the plant to channel its energy on growing the tubers instead of the flower . Regards

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. ;-)
