My dream would be to have an orange, lemon and lime grove stretching as far as the eye could see with a few Kaffir lime and other strange citrus dotted around. A dream inspired by a visit to Seville and walking through a magnificent orangery in nearby Cordoba, the dimension of the trees just tall enough to walk under, the colours of the fruit hanging against the shiny dark green leaves and the perfumes from the leaves, fruit and flowers was pure heaven and inspired me to grow citrus.
Further North, however the weather can be too cold and wet in winter to support citrus trees in the ground but just because we haven’t got an ideal climate, soil or conditions it is not going to stop me trying to grow citrus. I have found that we are able to grow some citrus fruit in pots and get a fairly decent harvest (for the size of the trees), these pots can be brought inside in winter bringing with them the scents and smells of an exotic orangery.
A few years ago my mum bought us our first Lemon tree (Citrus Limon) a small 2-3 year old dwarf variety called La Valette which produces pale yellow round aromatic fruit with a thin smooth skin. It bore 3 perfect fruit in its first year and so far fruits every year and sometimes twice, then my nieces, Ruby and Nelly, bought me a Kaffir Lime tree (Citrus Hystrix) for my birthday, a healthy looking brute which produces the wonderfully pungent leaves essential to Thai cooking as well as green gnarly fruit. Next i bought a lemon tree in Italy which is a standard form and produces long fruit with a thick skin (pictured above).
We are just at the beginning with our citrus adventure, not having grown any before, but our limited success so far is encouraging.
Temperature Most citrus need heat which is fine in the summer but should not be subjected to temperatures below 0, although some are said to survive up to -5, (ours have survived -7 with protection outside) to be on the safe side make sure to protect against frost and bring them indoors if it’s not possible to put them in a light frost-free place outside.
Soil a slightly acidic soil that is light, well aerated, well-drained and rich.
Feed with a diluted seaweed folia spray, a special ‘agrumes’ fertiliser or the traditional feed of diluted urine during the growing season. Mulch with well-rotted compost in autumn.
Water Citrus need a good supply of water but should never be left soggy or water-logged. A good soaking every few days in the dry summer, once a week (or when soil has completely dried out) in spring and autumn and rarely in winter, only when the soil is really dried out. Citrus will benefit from a spray of water on the leaves at night in high summer.
Space Re-pot every 2-3 years in Spring.
By growing our citrus trees in pots we can give nature a helping hand and move the small trees around to find the best micro climate for our weather conditions during the year. By putting them beside a south-facing wall in spring and autumn they are outdoors to benefit from the sun and heat on warm days but get the radiated heat from the wall to protect them from temperature dips. In winter we put them in an open cave which gets full low winter sun during the day and keeps some heat during the night to keep frost at bay. In summer they go out into the garden to benefit from full sun, occasionally pulling them into the shade if it gets too hot for a rest. By growing in pots we can also ensure that they have soil specifically tailored to them and a watering regime to suit.
Lemons Lisbon and Eureka and Villafranca are the most hardy and commonly grown. Mayer is recommended for conservatory growing and Citron de Nice is both hardy and resistant to cold. La Valette suitable for pots and fruits all year round, unripe lemons can be used as limes.
