@econetwork@mas.to @scogings@mastodon.world Potatoes like rich, fertile soil, so dig in plenty of organic matter, such as garden compost or well-rotted manure, before planting. If possible, do this the previous autumn or winter. Given that yours are already in the ground, you can apply a 10cm layer of compost or well-rotted manure around them, if you have it. The main thing I've found that improves the harvest is *regular* watering. Potatoes like it wet, but irregular wet-then-dry-then-wet (which we often get here in the UK) makes the potatoes lumpy. Too dry conditions can also cause "common scab" which makes rough patches on the potatoes. It's not a big problem because they're still edible, but they don't look good.
