Swift Seed Potatoes

Swift is one of the fastest maturing seed potatoes, and has been known to produce a good crop in as little as eight weeks from planting. Swift is easy to grow and will produce the quickest crop of new potatoes.

We recommend planting them closer than other first early potatoes and to keep the growing crop very well watered  especially in dry spells. Swift has a very short foliage and a bushy habit which makes it ideal for growing in containers and bags.

How To Grow Swift Potatoes

Soil preparation for first early seed potatoes

First, try and order your first early seed potatoes as soon as they are available to get the varieties to want to grow, which in most cases is around mid-January and early February onwards. Quality seed potatoes should be firm, and spring back into shape when lightly squeezed, as opposed to being soft and mushy. Potatoes can be grown is a wide variety of soil types but light, sandy soils and very heavy clay soil would perform better with the addition of generous amounts of organic matter or well-rotted compost. This would help to give the soil structure and aid drainage. An open sunny position is best for all potatoes.

If the soil is prepared in late autumn, it should be ready for planting seed potatoes in the following early to late March. It is advisable to not plant seed potatoes in ground that has been used to grow the same crop for 2 years or more as this would increase the possibility of disease. If you intend to grow in containers then the same rules and preparations apply. In all cases early seed potatoes will benefit from chitting. This is the process of encouraging shoots to sprout, by placing the potatoes in a light, cool place prior to planting.

Planting first early seed potatoes in beds

Select a suitable day from mid-March to mid-April, which is dry and clear of any frost. If growing in beds then lightly rake the prepared soil to a workable tilth. Next, dig a trench around 10cm deep and place the seed potatoes at 30cm apart. Ensure the potatoes have the rose end facing upwards. This will be the end with most shoots. Once lined out into the trench cover with soil and lightly firm. A light application of potato fertiliser can be spread over the top of the trench. There is no need to water the trenches at this point but water may be required should the following months be warm and dry.

If planting more than one row then space rows at 60cm apart. It’s a good idea to cover the trenches with a polythene cloche tunnel for the first few weeks, which will encourage the seed potatoes to grow quicker and could reduce the growing and harvesting time by as much as 2 weeks. Remove the tunnels when the shoots are about 10-15cm high.   

Growing first early seed potatoes in containers

First early potatoes can be successfully grown in a variety of containers but ideally they need to have a capacity of at least 30 litres. Barrels, bins, water-butts and oil drums all make perfectly large containers with lots of room for the new tubers to grow. Alternatively, any large clay, plastic or wooden container will suffice. In all cases drainage holes must be either present or drilled so that excess water can drain away freely. If the containers become water logged then the potatoes will very likely be damaged by rot.

Fill the container with soil to within two thirds capacity and plant the seed potatoes with the rose end facing upwards. Then cover the seed potatoes with 100cm of soil and firm. A light dressing of potato fertiliser can be added at this time and a light watering may be required if the soil is dry. Cover the container with clear polythene and wait until the green shoots appear. Once the shoots are about 75cm high remove the polythene and water lightly. Soil in containers can dry out very quickly in warm weather so ensure plants are kept well watered.
