GROWING CITRUS IN NORTH
FLORIDA
POSTED DECEMBER

2009
I love the colors that show themselves as the year
comes to a close: the vivid oranges, bright yellows and deep greens
of healthy, vigorous citrus trees heavy with holiday fruit. When
the citrus growing in my front-yard garden ripens, the most festive
time of the year has arrived.

For the past several years, Thanksgiving, Christmas
and New Year’s have marked the time of the year when we begin
enjoying yummy homegrown tangerines, juicy oranges, tangy kumquats
and fancy bright yellow lemons.
North Florida is not the ideal place to grow citrus
because, without some sort of protection, most varieties are not
cold hardy enough to withstand our sometimes freezing winter
temperatures, especially when the trees are young and small. Still,
it is not unusual for local home gardeners in north Florida to have
great success with citrus, especially those living closer to the
coast.
Of the three types of sweet citrus (mandarins,
oranges and grapefruits), only mandarins have sufficient cold
hardiness to be recommended for north Florida. Satsuma is a very
popular mandarin in north Florida and has cold-hardiness down to
about 20 degrees. Satsuma fruit ripens in October when temperatures
are still above freezing. It is considered the best choice for sweet
citrus in north Florida.
True Tangerines such as Clementine, Dancy and
Robinson have trouble standing up to temperatures that dip below
about 25 degrees for very long, so they are not generally a good
choice for our area. I have a Dancy or “Christmas” tangerine growing
next to the house that stands at least 15 feet tall (it needs a good
pruning!). While the tree has tolerated some fairly cold weather, it
does not bear much fruit the season following our colder winters.
This year, following last year’s mild winter, we have an abundant
harvest of this richly flavored Christmas fruit.
While there are no recommended varieties of sweet
oranges or grapefruit for north Florida, there are many orange and
grapefruit trees in dooryard gardens throughout our part of the
state. I have two orange trees in my front-yard garden. I really
love the fragrant, showy flowers and the delicious sun-drenched
fruit. I don’t have a grapefruit tree because we could never eat
that much grapefruit on top of the other citrus we already grow.

The oranges that we began harvesting shortly before
Christmas come from a Hamlin orange tree. Hamlin oranges are grown
for their juice but we find them to be great sliced and eaten, too.
Because the fruit ripens early it is unaffected by our usual winter
freezes.
My other orange tree is a Valencia, Florida’s juice
orange. These oranges are a late ripening variety. In Niceville,
they ripen in February. Our Valencia oranges are every bit as rich,
juicy and tasty as a fresh orange should be. When we cut into a
freshly picked Valencia orange, the sweet citrus aroma fills the
house – a real pleasure in the cold of winter!
Because the Valencia is a late ripening orange, the
fruit is often damaged by freezing temperatures in January or early
February. I planted my Valencia tree next to the house to help
protect it from the cold and wind, and that seems to help some. We
find the oranges to be delicious even when they are slightly freeze
damaged.
True lemons are not well suited for north Florida but
Meyer lemons, a lemon hybrid, are commonly grown with success in our
part of the state. These big, thin-skinned, juicy lemons produce
juice with a higher sugar content than the lemons we find at the
supermarket. While they are still tart, Meyer lemons have a sort of
flowery flavor and bright yellow juice. Meyer lemons are terrific
for lemonade and perfect to serve with seafood. If you are looking
for citrus to grow in a container, it’s the ideal choice because the
trees naturally grow to only about 10 feet.

Kumquats are the only acid type of citrus that is
considered cold hardy enough for our winter weather. Meiwa and
Nagami kumquats are most commonly grown here. We have three large
Nagami kumquat trees in our yard that produce heavy yields year in
and year out. The harvest generally begins somewhere near
Thanksgiving. Like Meyer lemons, kumquats also make nice container
trees.
In addition to the tasty fruit, kumquats and Meyer
lemons make attractive hedges and screens.
Unlike other types of fruit trees which grow more
slowly and may take several years to bear fruit, citrus trees are
vigorous growers and are eager to bear fruit, often doing so the
first year they are put in the ground.
How fast do citrus trees grow in north Florida?
Not quite NASCAR fast but pretty darn quick. The chart below details
the growth of my Hamlin orange tree and its annual yield over its
first 8 years.

Citrus trees are quite a bit easier to care for than
other types of fruit trees in north Florida. They are not bothered
by as many types of pests and disease. What’s more, the birds and
squirrels don’t eat the fruit, leaving it all for you and your
friends and family!
Look for citrus trees this spring at your local
garden center.
