Overwintering Lantana

Matthew Condon - Indiana.Matt - IN, Zone 5/6(Indiana Zone 5/6)December 16, 2012

I am experimenting with overwintering my Lantana, but they are having a problem. Now, I understand they won't be looking there best during the winter, but I don't think the leaves are supposed to turn black and fall off. Does anyone know what is going on here?

Too cold? soil too wet? level of soluble salts in the soil too high? reaction to something topically applied?

Over-wintering it where? indoors - outdoors - basement - @ what temp - how much light? Give us a little something to work with ....

Temps: 65-70 F
State: Indiana (46181)
Location: Indoors
Light: West facing window (very cloudy this time of year)

I dug them up after frost shot them down, cut them back to a few inches, cleaned off the roots (they looked very healthy), repotted them in fresh potting mix. They have been growing very well.

I only water them when they start to get a little dry, but I did take them out and give them a good soaking with the garden hose.

The west facing window is a patio door. It could be leaking cold air at night.

A picture of the whole plant would be helpful.

This seems to happen to a lot of plants in the mint family when you try to move them indoors - it's certainly the case with basils. The plant also appears etiolated from a lack of light.

The cause is probably some combination of 1) low humidity indoors, especially when central heating is on 2) root dysfunction/rot from soil conditions being too wet.

Go back to only watering when it feels dry. Try making a clear plastic tent of some kind to increase humidity. A simple compact fluorescent positioned over the plant, as close to it as possible, may help too.
