This is an easy guide with pictures showing exactly how to go about planting potatoes in August. We will add a final picture on the right when December 25th comes along and I harvest some of our potatoes on Christmas Day!
A crop of potatoes in early October from an August planting.
Order your seed potatoes from an online supplier, we ordered ours from Dobies. They supply potatoes which are ready to be planted immediately and require no special treatment.
We ordered the variety Vales Emerald but demand was too high and we actually received Maris Peer. This is a second early variety which is good for boiling, chips and wedges. It's also good cold for salads. Very tasty!
Clear an area of land from weeds and dig it over to a spade's depth. Draw furrows (three in the picture to the right) about 12cm / 5in deep and lay the potatoes (any way up will do) in the furrows at the recommended distance apart. We spaced our potatoes 38cm / 15in apart, with the furrows 50cm / 20in apart exactly as in the instructions. Planting distances vary with variety so read the instructions carefully.
We planted our potatoes on 4th August and this is a
picture them three weeks later on 25th August, not bad
progress by my reckoning! Don't plant potatoes on land
that has been used for potatoes over the past two years and
if the soil is low in nutrients after growing a crop
earlier in the year, apply some well rotted compost or
general purpose fertiliser on the surface of the soil.
When the potato plants are around 25cm /9in
high earth them up. To earth up potatoes, simply use a hoe or
rake to pull up earth between the rows around the stems. No
problem if some of the leaves are covered, the potato plant will
simply grow through.
Here are the potatoes on 13th September, yes really only
6 weeks later!
It's all down to the soil which has been warmed by the
last 2 months of summer. These potatoes are about a month
from being ready for harvest. Our ambition of potatoes for
Xmas may have been premature because the potatoes have
actually matured even earlier than we expected!
Potatoes planted in August are prone to blight infection if the long periods of damp occur. This is a serious disease which can be avoided. First, pick a resistant variety. Avoid the following varieties if you can: King Edward, Arran Comet, Arran Pilot, Epicure, Foremost, Golden Wonder, Home Guard, Kerr�s Pink, Majestic, Sharpe�s Express and Ulster Chieftain. Varieties which have some resistance to blight include Cara, Estima, Kondor, Maris Peer, Pentland Crown, Valor and Remarka.
Second, spraying with Bordeaux mixture before the plants are infected provides a good degree of control. Note that tomatoes also suffer from blight so the same advice applies to them. If the weather is warm and damp for a few days, then start spraying with Bordeaux mixture, especially if the forecast is for more of the same weather. Spraying should occur at 14 day intervals or according to the instructions. If you see any leaves with brown freckles on them, remove and burn as soon as possible because they are infected with blight.
The potatoes should be ready for harvest when the plant
stops increasing in size. At this time flowers or buds will
normally appear. Harvest only those you need. Mature
potatoes can remain in the ground for a month or more with
no ill-effects. On the left is a picture of Maris Peer
potatoes. Click to enlarge.
If a frost hits the plants, the tops will go brown
and start to die. However, the potatoes under ground will still
continue to grow although more slowly. Good luck with your
potatoes, and hopefully a Christmas harvest will be yours.
