How to plant winter potatoes
This is where you need to be careful. If you live in the UK, you can’t just plant your spuds outside in winter and expect them to grow.
To grown winter potatoes successfully you need to use a greenhouse (preferably heated), Coldframe or grow them indoors in a porch or conservatory.
You need to ensure the tubers will be kept frost-free. A well-insulated greenhouse in a good spot may work well even without heating.
Planting potatoes to grow inside
A great way of growing potatoes in winter is to grow them inside. A porch or conservatory makes a great spot. To start you need to find the right pot, we will outline how to get the most out of you indoor over winter potatoes below.
- Find a large, deep pot. Ideally, over 35cm deep and wide.
- Add some compost to the bottom, garden soil mixed with compost will work just as well. Add around 10cm if you have a small pot, if your pot is deeper, you can add more. Roughly halfway will be a good guide on larger pots.
- Add one potato tuber per pot
- Cover the tubers with soil; ideally 20cm of compost should be placed on top of the tubers to cover them adequately.
- As the potatoes grow and leaves develop earth up your potatoes just as you would if you were growing them outside. This is where larger pots will work well as they leave more room to earth up.
- Ensure the room they are growing in remains frost-free all winter.
- Feed and water the potatoes throughout the winter. A general-purpose fertiliser will be sufficient.
- When the leaves begin to yellow, your spuds are ready for harvest!
- Did you know you can remove the foliage but leave the spuds in the ground until you are ready to eat them?
