Answer: Lantana typically thrives in hot weather. Your soil may be a little different than that of your neighbors which may account for the plant's failure to thrive in your garden. I think daily water is excessive. If you keep the soil too moist it drives out oxygen - something the roots need. Try watering deeply every 3-4 days during the hottest part of the year. White flies can be controlled with insecticidal soap. Spray in the early morning or at dusk, when the pests have settled down onto the plant and you should be able to get most of them. Repeat sprays will probably be necessary. Adjust your watering schedule and prune the lantana back a bit to encourage healthy new growth. I think it will respond by flowering well for you.
