Despite the relative mildness of Louisiana winters overall, severe freezes do occur, and they can be devastating to tropical plants.

All it takes is one night of temperatures in the low 20s or teens to severely damage or kill your tropicals.

The possibility of freeze damage in winter should always be considered when growing citrus trees. A variety of factors determine how much freeze damage is done to a citrus tree when a freeze does occur.

The best time to plant a citrus tree is in late February or March. This gives trees an entire growing season to establish before their first winter in the ground. This is a real advantage.

Colder weather is coming this week. As always, whenever the first cold snap hits in this season, gardeners panic just a little bit.

Remember that this will not be a hard freeze.

Temperatures below 30 degrees are a hard freeze and cause a lot of damage to tender plants. However, these temperatures we're expecting aren't going to cause a great deal of damage, so relax a bit.

Temperatures dropped down to around 20 degrees in the Baton Rouge area during the recent arctic blast. A freeze this severe can cause significant damage to tropical plants, even plants that were covered or otherwise protected.

All it takes is one night of temperatures in the low 20s or teens to severely damage or kill many of our tropicals.
