Add compost/composted manures or fertilisers to the soil to put nutrient back into the soil for the next planting.

Anyone grow True Seed Potatoes in zone 10? Curious when you start your seeds. My seeds are low dormancy and short-day length. Start seeds in August, maybe, to plant out in October?

Have a look at https://livingseeds.co.za/potatoes - they sell seed potatoes and ship to anywhere in SA (at the right time of the year). They always stock standard coloured potatoes as well as occasionally some novel heirloom ones. Also on that page is a link with guidance on growing potatoes. Pre-orders are opening soon, shipping is early August ready for you to plant.

You need to work out your climate zone from the BLUE CLIMATE ZONE TAB at the top of the page. Then check when to plant. Buy from seed selling websites, nursery, farmer produce store, hardware & gardening stores.

Could I plant certain potatoes in zone 7B in June? I live in Southampton County, Va.

I live in Zone 7b in Arkansas. It's been an unusually cool and wet spring / summer. I planted four varieties in a prepared bed. (composted manure was tilled in.) The varieties were Pontiac red, Kenebek, Russet and Yukon Gold in roughly equal amounts, purchased prepackaged at a farm store. The seed potatoes were sown in rows 12 -18 inch spacing on Feb 28 by burying shallow, then covering with several inches of composted manure followed by several inches of straw, two bales on roughly 120 sq feet. I did not document when they sprouted but it seemed weak initially but success rate of sprouts was eventually good. The composted manure is weedy and so was the straw, eventually weed pressure was high so I covered with another layer of composted manure. ( I don't remember the date and the plants were 20 inches or so tall, some in blossom. ) Although at the time of harvest the bed was heavy with weeds again that worked long enough to bring in a harvest on June 4th. While harvesting the soil was still quite moist, only two or three potatoes had rotted and the yield was about 2 to 3 nice sized potatoes per plant with up to three small potatoes per plant too. I followed the harvest with a sweet corn. I contemplated a second potato planting but i think it will be too hot. I'm going to make a deep raised bed from pallets manure and straw out in a shady part of my homestead and try a few to see what happens. Hopefully that helps.

When growing potatoes what fertilizer does one use
28 Apr 20, Anon (South Africa - Summer rainfall climate)
Just look for a general all round gardening fertiliser. If you look at all the fertilisers for different crops there is not a big difference in the NPK of them. Depending on your soil 8-12N, 3-6P, 3-6K. I read of fertilisers like 10, 10, 10, and 8, 8, 8. I don't know where you buy them (USA stores?).
