My ten-inch pots with a single Sarpo Mira seed potato have yellowing foliage and don't look like there's much more in them so I decided to drop one of them today and see what was inside. The roots were very strong with a lot of potatoes looking very healthy. Perhaps they would have done a bit more. But still it gave 600g of good potatoes, more than the average of my Pentland Javelin pots. So I have high hopes for the other two pots and even higher hopes for the 30 litre bags to come later.
The pot was planted up on 31st March, 118 days ago.
The empty pot has been replanted with six leeks using the same compost rejuvenated with some blood, fish and bone.
Update: The other two 10 inch pots gave 610g each. So a good average for a small pot.
The first 30l sack was turned out on 12 August. Only 840g with a lot of scab so not very successful. The haulms were dying but the potatoes were very immature. 2nd sack gave 1092g with some good big ones! 3rd - 703g ! 4th - 944g 5th 578g in one big one!
Xtra! A sprouted "shop potato" was grown in a clay pot with unimproved garden soil and a handful of blood, fish & bone. Harvested on Oct 19th it gave 880g of good size and quality potatoes. I won't be paying for seed potatoes any more!
The fridge saved pentland javelins planted in July have been harvested. They gave a fair crop of very good quality.
