Seed Potato 'Maris Bard' - Gro-Kit

Marshalls Garden

Catalogue Code: 10907115

Sale price

Currently Out of Stock

Regular price £19.46
At Marshalls we are excited to announce that one of our favourite potatoes is now available as a Gro-Kit. We love Maris Baird for its high yielding shallow eyed oval tubers. Including 1kg of Seed Potatoes, 75g of fertiliser and 3 x Grow Sack. This kit contains all you need for a successful harvest - just add compost!

Pack Contents: 3 x Grow Sack, 1kg of Tubers & 75g of Feed


  • High yields ready for your summer salads
  • Doesn’t discolour when boiled like other potatoes
  • Offers excellent all round disease and pest resistance
  • Comes with our exclusive FEEFO 5* rated potato fertiliser and Gro-Bag

If you are looking for big yields and shallow eyed oval tubers then Maris Bard should be your potato of choice. When boiled this type of potato holds its shape well, that means it’s perfect for summer salads or boiling in general.

The kit contains:

  • 1kg pack seed potatoes (approx. 12-15 tubers)
  • 75g potato fertiliser
  • 3 x Potato Grow Sack (50L)

Planting seed potatoes into the well-sized planter is easy. Plus, it enables you to easily locate it either on the side of your allotment, patio, backyard or even on the balcony; wherever is most convenient to you.


Once you receive your kit, it is best to start to 'chit' your seed potatoes as quickly as possible. This is a proccess that accelerates the growing process even before they are planted in the soil.

  • Select a top and bottom of each seed potato by checking for 'eyes' or dimples in the skin where the shoots will emerge from. The one with the most eyes can be the top.
  • Place these in a container that holds the potato upright with the top facing upwards - an old egg box is perfect for this - then simply place these in a cool, bright place and wait!
  • The shoots will start to grow slowly; you need them to be approx. 2-3cm long and with a purpleish hue to them before they are ready to plant. This should be approx. 4-6 weeks.
  • Now prepare your grow bag by adding suitable compost into the bottom, mixing in some of the fertilser and filling approx. 1/3 of the way up.
  • Plant your tubers in the soil by pushing them into the soil surface with the new shoots facing upwards. Cover with more soil so the tubers are not visible. Plant 3-4 tubers only per bag. More tubers lead to a greater yield but with smaller potatoes, while fewer tubers result in fewer potatoes that are larger in size.
  • Water the soil thoroughly. Once the shoots start to emerge wait until they are approx. 10cm high and add more soil until the shoots are almost covered again.

    Dont worry, this method encourages more potaoes to be produced but also stops the newly forming potatoes going green. This occurs when they are exposed to sunlight, hence you should add extra soil to maintain darkness.

    Continue this process every 2 weeks or so, until the shoots are out the top of the bag and you have filled it to about 3cm from the rim. The shoots will still continue to grow out of the top and may get very large - no need to worry; this is a sign the process is working.

    Keep watering often, as potaotes are very thirsty! You may even get flowers on your shoots, but wait until these shoots start to turn yellow and flop over. This is the magical moment when you know your potatoes are ready. Gather up the potatoes, rinse them off, then enjoy their deliciousness! Many varieties are very good at storing, somewhere cool and dry, away from vermin. Good luck!

    How you will receive your plants:

    Selected by our team of experts and sent from our nursery, you will receive seed potatoes in early January in a breathable net bag that can be recycled as for plastic bags. This keeps the potatoes together in a pack that is nice and airy – perfect to keep them healthy while in transit.

    Can’t plant straight away?

    Ideally, you should aim to start chitting your potatoes (see below) within a week of receiving them, but if this is not possible, store them in a cool, dark place until you are ready to use them.

    Planting tips and hints:

    To protect your potatoes from frost damage, cover them with a horticultural fleece when temperatures start to plummet at night. If your planters aren't too heavy, bring them indoors on cold nights and return them outdoors during the day.

    These potatoes are happiest when planted in full sun.

    Harvest first early potatoes in June or July, second earlies in July-August and maincrop potatoes from late August-October once their leaves have yellowed.
