When you listen to any of those garden question and answer sessions, it seems the lemon tree always tops the ‘most asked about’ list. But it’s not because lemons are all that troublesome. It’s because they’re so widely grown that almost everyone has one in their yard – hence, lots of questions!
Eureka produces fruit almost year round in warm areas. The fruit is virtually seedless and has a thin skin. However, as lemons go, Eureka isn’t particularly cold tolerant. Villa Franca is a relative of Eureka that does better in inland areas, as well as in the subtropics.
Lisbon develops into a large, prickly tree that produces a heavy winter crop. It is very hardy and more tolerant than Eureka to both cold and heat.
Meyer is a small grower that is thought to be a cross between a lemon and an orange. Its small size means it’s suited to pot culture and its cold tolerance sees it used widely in frosty areas. Lots A Lemons is a dwarf form of Meyer. In order to guarantee perfect drainage, Lots A Lemons should be grown in a pot.
Lemons trees need sun and good drainage. Anything less is a compromise. If the soil is heavy, you can build a raised bed, dig in organic matter and gypsum or, safer still, choose a small lemon variety that can be grown in a pot. Most of the popular lemons are available on a dwarfing rootstock called Flying Dragon that restricts their size by about half. Potted lemons should be grown in a good quality mix (such as Yates Potting Mix with Dynamic Lifter) and moved into larger containers as they develop.
Lemons planted out into the ground don’t like competition, so remove any grass from the base and keep the root area mulched with a light organic mulch. Don’t let the mulch touch the trunk of the plant because this could encourage rotting in the stem.
Feed your citrus with Yates Dynamic Lifter Soil Improver & Plant Fertiliser three times a year, in early spring, summer and again in autumn. When the tree starts to produce fruit (normally in its 3rd year), feed weekly with Yates Thrive Citrus Liquid Plant Food.
An annual treatment with a small amount of trace element mix is also a good idea.
Give a winter treatment with Yates Limes Sulfur to clean up white louse scale on the trunk. This could also help with getting rid of young stink bugs.
