Potato Gardening
Monday, July 26th, 2010 | Author: Home and Garden
Potato gardening is becoming more popular and each year potatoes are planted by an ever increasing number of vegetable gardeners in their home gardens and allotments.
And its not surprising why. They are easy to grow, look after, harvest, store, cook and the taste is just fabulous.
Now the humble potato originates from the highlands of Ecuador and Peru and they are a species of perennial plants grown for food in most countries around the world. They are one of the worlds most important staple food crops along with rice maize and wheat.
There are thousands of different varieties of potato and they are the most common food grown and eaten in Western civilization.
They are part of the Solanaceae family and known botanically as Solanum Tuberosum. They are related to deadly nightshade and tomatoes.
In temperate climates potatoes are grown three times a season, as first earlies, second earlies and main crop, giving a succession of crops ready for harvest from May through to October.
Potato growing is easy and the best place is a sunny spot where they will be in the sun most of the day and not in shade. Avoid areas that are frost pockets.
Just about any soil type will do but to get the best size and tastiest crops dig the ground over to at least a spade depth in autumn, fall, and add plenty of well rotted manure or garden compost and leave the weather to break it down until the following spring.
You should only use certified virus free seed potatoes from reputable suppliers.
You will need to buy them as early as possible so you can chit them six weeks before planting.
What’s ‘chit’ them?
Seed potatoes need to be forced into growth before they are planted to produce the best crops. They need to produce strong shoots.
Now if you look closely at a potato you will see they have a ‘rose’ end which is usually the largest end and it is where the ‘eyes’ are formed and where the shoots will grow from, which need to be about 25mm (1 inch) long before they are planted.
Chitting is easy, just place your potatoes in egg boxes, rose end uppermost and keep them in a cool, light place which is frost free and out of direct sunlight.
You could use a seed tray, flat, or something similar with about an inch of dry horticultural sand in the bottom and stand your potatoes, rose end uppermost, in them.
First earlies are planted in March, Second earlies are planted in April and main crop are planted in late April to early May.
In spring and two weeks before planting your seed potatoes sprinkle a well balanced fertilizer over the ground and work it into the soil with a rake.
The best way to plant your seed potatoes is to make a ‘V’ shaped trench with a draw hoe or an up-turned rake to a depth of around 15cm (6 inches) deep.
Just place your chitted potatoes, being careful not to break off any shoots, in the bottom of the trench and space them 30cm (12 inches) apart for first earlies and 70cm (28 inches) apart for second earlies and main crop and draw soil over them making a slight mound about 10cm (4 inches) high.
Looking after them is easy, as the shoots appear draw soil over them which will protect them from any late frosts and increase you’re crop size. This is known as earthing up or hilling.
Keep weeds to a minimum and if you are using a hoe don’t go to deep or you will damage the growing potatoes and roots.
Keep them well watered especially as the plants start to show the first signs of flowers.
Every couple of weeks give them a good feed of a well balanced general fertilizer just before you water them.
Harvest times will depend on local weather conditions, site and type of potato but they will be ready to harvest when they are in full flower, just dig them up carefully with a garden fork.
Its best to harvest first earlies only as you need them and dig one or two plants up at a time. Leave the rest to grow on until you need them but dig them all out by July. First earlies do not store well so use them as soon as you can.
Second earlies and main crop potatoes do store well and can be stored in trays or hessian or plastic string bags. Keep them in a cool dark, frost free place.
Potatoes don’t suffer from many diseases and pests and buying certified seed stock goes a long way to disease control.
The only thing you may encounter, through poor soil conditions, is blight, scab or blackleg and this can mainly be avoided by rotating crops every year so you don’t grow the same crop in the same piece of ground for four years.
The only real pests are slugs which usually are not to much trouble and are easily controlled.
You can grow potatoes in containers for real early crops in your greenhouse or conservatory.
Plant four or five seed potatoes towards the bottom of a 30cm (12 inch) pot filled with a peat free compost in early to mid February and if your greenhouse or conservatory is unheated protect the containers from frost with gardening fleece, bubble wrap or sacking.
As soon as shoots start to appear remove the fleece but if frost is forecast cover them over again.
They can moved outside to the sunniest spot when all danger of frost has passed.
Always keep the compost moist, but not water-logged and feed them every two weeks with a soluble or liquid general purpose fertilizer.
