What is mounding up and why should we do it? Some great advice to help your potatoes grow healthily.
The chitted potato will take around 2-3 weeks to break the soil once planted.
It's tough love time - cover the shoots up to encourage downward growth for more room for the new tubers
Don't worry if you haven't planted yet. Sometimes chitting takes longer than expected and sometimes the weather comes into play, and then of course there are times that life throws a curve ball. Just get the tubers in over the next week or so - Potatoes do not mind being chitted for longer and will still grow incredibly well.
When the emerging shoots come through, you need to “earth” or “mound” them up – this is counter intuitive. Do this several times. This encourages downward growth. Earthing up potatoes will increase the length of underground stems that will bear potatoes.
Mounding or earthing up means drawing up soil around the stems as they grow – to protect shoots from frost damage in late spring and more importantly, new tubers are jostling for space and this gives them more room ensuring the developing potatoes aren’t exposed to light, which turns them green and inedible.
It’s a simple process – once the shoots are about 23cm (9in) tall, mound soil up around them to form a ridge along the row, leaving just the top 10cm (4in) of the plants visible. As the stems grow taller, repeat the process several times, a few weeks apart. The final height of the ridge should be 20–30cm (8–12in). Some people advocate covering the entire plant – you could experiment to see which works best for you
If you are growing in grow bags or buckets, keep adding soil over a few weeks until it is at the top of the container.
Potatoes like to be watered but not water-logged and so ensure your pot or area has good drainage. Even watering throughout the season is important.
