Vegetable growing

Christmas potatoes

I shared a couple of weeks ago that C and I bought our Christmas potatoes in one of my favourite local garden centres. Christmas potatoes are potatoes that you plant in late summer/early autumn and harvest at around (or just before) Christmas time, they are also known as Autumn planting potatoes but I think the name Christmas potatoes has become more popular in recent years. Christmas potatoes only really work as new potato varieties (also known as earlies) as they have a shorter growing period so enough time to mature before the winter sets in. We have chosen two different varieties, Charlotte (a favourite of ours) and a new one to try Pentland Javelin. Now late planted potatoes such as these are best grown in bags as the open ground can get pretty cold in winter. Then ideally before the first frost you want to move the bags into a greenhouse (or a conservatory) to keep them a bit warmer. You can get your potato bags from a variety of places but I found them cheaper online than in the garden centres. 

I find it best to roll down the sides of your bag before you start as then they are easier to fill and also they get the best access to sun. 


First fill your bag with about 10-15 cm of good quality compost and water it well. Then place 2 or 3 seed potatoes on top, with the best looking sprouts facing upwards.

Then cover with another 10 cm of compost and lightly sprinkle with water again. 
Then they just need leaving, until you get your first foliage you will need to ensure that the soil is kept moist so try to check it every couple of days. Then once they have a good amount of green foliage sprouting (say 10 cm plus) then completely cover with compost again (roll the bag sides up as required). Then repeat until the bag is full. This is known as earthing up and will help to maximise your produce. 


Now the astute amongst you will have noticed that I earlier said you will have to move the potatoes inside before the first frost. Now the potato bags might be rather heavy once you start filling them with compost so for us we have already sited them where our greenhouse will be constructed. Obviously not an option for most people but it is something worth remembering before you overfill your bags and then can’t move them. Although the bags do have handles to move them, I don’t imagine they will do too well when they are full of compost. Has anyone else grown potatoes in bags this year or fancy trying it?

  1. Christmas potatoes just sound so cute! I can’t wait to see what they are like when they’re ready.
    I’ve never tried growing anything before but like the idea of the bags that can be moved around.
