The origin of citrus is uncertain. China is the most likely
origin of the lemon. The Arabs had certainly introduced the lemon and the sour
orange to Palestine and Persia by the beginning of the 12th century
and from there to other Arab possessions in Spain and North Africa.
We can grow satsuma oranges in the open ground in our area
and after a few years a tree can produce more than you can eat.
Lemons are a different matter. I really prefer to harvest my
big juicy Meyer lemons rather than the commercial lemons available in the
grocery. Two cultivars dominate the commercial market: Garey’s Eureka and
Lisbon. Most lemons can be harvested throughout the year. Lemon trees do not
become dormant in the winter and tend to produce some flowers throughout the
year. However this makes them more vulnerable to cold weather than oranges and
they will usually shed their foliage if the temperature drops below 23⁰F and
fruit can be badly damaged below 28⁰F and serious damage can occur to the wood
when temperatures fall below 19⁰. Improved Meyer is slightly hardier than true
lemon and may be a better choice for home gardeners in a cold climate. Meyer
lemons are actually a hybrid between a lemon and a mandarin or an orange. It
was first found growing as a pot plant near Beijing, China in 1908 by Frank
Meyer, a plant collector for the US Department of agriculture. In the 1940’s
the Meyer lemon was discovered to be a carrier of a citrus virus. In the 1950’s
California-based Four Winds Growers discovered a virus-free clone and this was
released to the market as ‘Improved Meyer’ in the 1970’s.
Citrus do not do well as house plants. Our homes are too dry
and not sunny enough. But I have found growing them in pots to be satisfactory.
In our climate the pots may be left out all year, particularly if in a warm
spot. We have few hard frosts and rarely do they last long. If you can move
your pots into the garage or similar space for the short time that the
temperature is bad, you can have some success with lemons.
Most mature citrus trees do well in a 15-in. pot. They
definitely prefer a terracotta pot because it is porous and good drainage in
essential. The main disadvantage of the terracotta is its weight. Citrus grow
better in a loam-based (soil-based) material which is well aerated and provides
good drainage. The best pH for citrus is between 6.0 and 7.0. Citrus need a
number of trace elements if they are to grow well. One expert recommends Vigoro
Citrus and Avocado Granular Plant Feed which can be had from Home Depot.
Careful watering is extremely important with citrus. They
should be watered until the soil is soaked but drainage is essential. Do not
allow to stand in water. Water with rain water if you can.
So if you want some very nice lemons that you cannot buy in
the grocery, get yourself a 15-in. terracotta (or other if weight is a big
problem) and buy a ‘Improved Meyer’ tree and get started this spring for fruit
this fall and winter.
Lemons remind me of spring. If we didn’t have lemons there
would be no lemonade and no lemon bars. I love the sweet-tart flavor of lemon
bars. I found a recipe created by Chef Dolester Miles (pastry chef at the
Highlands Bar and Grill in Birmingham) and she admits she likes all things
lemony and this is her go-to classic version of lemon bars.
I am having a meeting of the Norwood Women’s Club this week
(Norwood is just down the road in Louisiana) and for my afternoon tea I am
serving these lemon bars for one of my treats.
