How do I grow asparagus in pots?
Posted by Dobies Staff on 18 December 2013 12:43 PM

Asparagus crowns can be grown in a large pot or planted direct in the garden.

If you wish to grow the asparagus in a pot then it needs to be placed in a sunny, sheltered position and wated regularly, especially during the summer and dry spells. Feed the plants regularly with a balanced liquid feed about every 7-10days. On cold nights cover the potted plants with horticultural fleece to prevent frost damage. Allow the new plants to become established for the first year before harvesting any spears, leave any spears that develop to grow into the ferny foliage.

In autumn once the foliage has turned yellow it should be cut back to ground level.

If you prefer to grow your asparagus direct int he garden then the crowns need to be spaced 38-45cm (15-18") apart. Keep the plants well watered in dry spells. In March feed with a general fertiliser. Only a few spears may be harvested in April and May during the second year when they reach about 15cm (6") in height. By the third year all the spears can be harvested but stop cutting before June to allow the spears to become foliage which then feeds the plants and helps to produce spears the following year. Once the foliage has been cut back in autumn apply a mulch of well rotted manure or garden compost around the plants.  

To harvest slice through the spears with a sharp knife just below the soil level making sure not to damage the crown or roots. Once harvested ideally use the spears straightaway or put in them in the refrigerator salad draw. Enjoy!
