Reply:Put coffee grounds on the soil near the base of the plant. Starbucks gives away bags of coffee grounds for gardening purposes. When my lantana starts to get a little light, I give them some coffee, and they brighten up! I'm sure there's some chemical reason: low ph or whatever, but...I'm more pragmatic. It works--so I don't need why.
Reply:It means soon they will fall, they′re are dying.
But it′s natural, they don′t last forever, I mean the leaves, not the plant.
Reply:Most likely you are over watering it.
Water thoroughly once a week and make sure the pot has good drainage.
Reply:Are you giving it adequate food/water/light?
Reply:Overwatering or overfertilizing. Check the soil - if it isn't getting enough water the soil will be dry.
Reply:They may need a bigger pot.
