Sign-up now for your class to take part in 2020 - closing date Friday 24 January 2020

Kits are limited so don’t delay.

Please be aware that ONLY Primary schools in England, Scotland and Wales (5 to 11 year-olds) are eligible to take part in the GYOP project and will be allocated kits in 2020.


Start chitting your seed potatoes on Tuesday 18 February 2020, this will take about two weeks.

Chitting will speed up the ageing process of your potatoes, by exposing them to light and, more importantly, a bit of warmth. This will cause the eyes of the seed potato to start sprouting and should result in a better crop.


Tuesday 3 March 2020

All schools taking part in the GYOP competition will be planting on this date. This year we have extended the project by 1 week to give you 15 weeks to grow a successful crop before harvesting on Tuesday 16 June 2020

By now, you should by now have chitted your potatoes but don’t worry if not, you can still plant them, just be extra careful not to over water them before they have had a chance to get established.

Also, don’t forget to label your grow-bags to help identify the variety growing. You could win a prize for your school by showing us how you labelled your bags.


15 weeks from planting to harvesting.

To grow a successful crop of potatoes in your grow bags, your potatoes will need: light, water, food, space and air.

Make sure you find the perfect spot to stand your bag, keep the soil moist but not wet and don’t forget to top up your soil as the plant grows, to give the potatoes plenty of room.

Watch out for late frosts too, potato plants hate frost!


Tuesday 16 June 2020

Now is the exciting time when you find out if all of your hard work has paid off, just 15 weeks since planting.

If you remove the green tops from your plants, it makes them easy to pull out of the bag without damaging them, this means you can re-use the bags to grow something else.

Once out of the bags, the fun begins; roll up those sleeves and rummage through the soil to find your potatoes, just watch out for the mother tuber!!
