We sell certified seed potatoes which are
supplied as grade 33-55cm seeds. 30 seeds weigh
approximately 2-2.5kg (salads 1.5-2kg).
Step 1 –
Fill one third of your Patio Potato Sack (15-20cm) with the damp compost
and place the seed potatoes on top of the compost. Then cover the seed potatoes
with a further 10cm of compost up to half of the sack.
Step 2 –
As plants start to grow and green foliage appears add more compost
around them to slowly fill up the potato sacks to a few inches
from the top. We do this as the potatoes grow from the stem beneath the
soil level so we want to keep that stem covered.
Every time that you add more compost you can feed the bag
with a general potato fertilizer which is high in potash.
Make sure you keep the compost moist at all times, but not too moist
as the tubers/seed potatoes will rot if over watered at this stage.
Step 3 –
For a bumper pack, increase watering when the plants
flower (this is when the tubers begin to form). They will usually be ready
for harvesting once the flowers begin to open.
Step 4 –
About two weeks before the potatoes are ready to harvest
you should cut all the growth off at ground level to prepare
the potatoes for lifting, making the skins tougher and less
likely to break on lifting.
