Potato varieties for containers

Pfa.....?????

Hi Sherlock, when did you plant your potatoes?
Did you water them well as the weather has been very warm and dry.
How many potatoes per pot.
We're they outdoors or in a greenhouse or poly tunnel.
We're the seed potatoes saved or bought in a garden centre.
Sorry to hear you were disappointed but there are so many things to take into consideration apart from the growing medium.

Using ReCycled Compost is not uncommon, depending on what crop was grown previously.
personally, I Recycle my compost through a 'Dalek' type bin overwinter, but seperate it into previous crop lots.
Next year I mix with FYM and New MP but dont grow the same crop as previous year.
Potatoes are quite Nutrient reliant and will definitely respond to FYM rich soil, but they also require the correct levels of P+K to maximize nutrient efficiency.
Sometimes cheap fertilizers appear attractive but do not always contain/do what it says on the tin...!!
Seed Potato selection and source is important to avoid seed borne disease etc, check sites on Google Re seed suppliers.
As far as Variety .....Rocket has been my preffered variety for first earlies, this year I grew Accord alongside and found them to br 7-10 days earlier and higher yielding.
lady 'C', after 2 years growing, have been disappointing and succumbed to black Leg, (seed borne).
Cassablanca, late for a first early, but are growing on.
Older varieties such as Maaris Piper ,Estima for main crop, in my mind stll take a lot of beating for yield and flavour/useage.

Pink Fir Apple?

Having grown potatoes in 30 litre buckets for several years now I have come to the following conclusions:

1. Starting potatoes off in the greenhouse is fine if you want very early, small new potatoes. If you want to grow them on for bigger potatoes or use the greenhouse for something else, they are better started off where you want to grow them and not moved. I think this is because the plants put roots through the drainage holes at the bottom of the pots, and don't like having these broken off. I have never had a big yield from a pot that has been moved. I find covering them with a polythene cloche which can be removed when the weather warms up works well.

2. Buckets of potatoes need more water than you think, but pouring this on top of the stems risks blackleg. Give them the option to get some water from below by putting the bucket on soil or organic material, or give them a drip tray. You may still need to water from the top, but try to avoid soaking the stems repeatedly. Lack of water leads to smaller yields and dry, floury potatoes.

3. Potatoes will grow well in shade but for maximum yields plenty of sunshine is needed.

Apart from specific varieties such as Rocket and Sarpo Mira, which are known for huge crops, I think the above factors are more important than the variety.
