	Interactive Urban Irrigation Tool for Florida (AE485) A team from UF/IFAS has developed an app for optimizing your home irrigation system using real-time weather data from the Florida Automated Weather Network (FAWN). Learn more in this 5-page fact sheet written by K.W. Migliaccio, N.A. Dobbs, W.R. Lusher, J. Fan, M.D. Dukes, K.T. Morgan, and B. Ferraro, and published by the UF Department of Agricultural and Biological Engineering, March 2012. http://edis.ifas.ufl.edu/ae485
	Camellias at a Glance (CIR461/EP002) Native to Asia, the first camellia plants were brought to America in 1797 and grown in New England greenhouses. Over the last 200 years, they have proven to be dependable additions to the southern landscape, where they grow and bloom with minimal care in most inland areas of North and Central Florida. Camellias are long lived and function well as foundation plantings, screens, accent plants, background groupings, and hedges. Camellias flower in the fall and winter when few other plants are blooming. For the remainder of the year, their glossy, evergreen foliage, interesting forms and textures, relatively slow growth, and low maintenance make camellias excellent landscape plants worthy of more use.

		*Palm Aphid Cerataphis brasiliensis* (Hempel) (Insecta: Hemiptera: Aphidae: Hormaphidinae) (EENY520/IN924)** The palm aphids are the only aphids known to infest palm plants. High populations occasionally become severe in nurseries and the landscape, and can cause substantial damage to young coconut palms. They pierce palm foliage and suck out the plant phloem content, causing yellowing of the tissues and loss of plant vigor. In addition, honeydew production by the aphids promotes sooty mold growth that can limit photosynthesis. Palms heavily infested with aphids can experience stunted growth. This 4-page fact sheet was written by Bonnie C. Wells and published by the UF Department of Entomology and Nematology, March 2012. http://edis.ifas.ufl.edu/in924
			*Saddleback Caterpillar Acharia stimulea* (Clemens) (Insecta: Lepidoptera: Limacodidae) (EENY522/IN923)** Acharia stimulea is best known as a medically significant species. Its spines are strong, acutely pointed, and hollow. They embed deeply into tissue and break off, and can interrupt healing as the protoplasm from the venom glands dries into the tissue area. The venom itself can cause a systemic condition called erucism or acute urticaria, for which severe symptoms may include migraines, gastrointestinal symptoms, asthma complications, anaphylactic shock, rupturing of erythrocytes, and hemorrhaging. This 9-page fact sheet was written by Christopher S. Bibbs and J. Howard Frank, and published by the UF Department of Entomology and Nematology, March 2012. http://edis.ifas.ufl.edu/in923
			Central Florida Gardening Calendar (ENH1189/EP450) Apply horticultural oils in January. Plant caladium bulbs in March. Watch for thrips, scale, and mites in May. Plant palms in June and July. Calibrate your sprinklers in September. This 10-page fact sheet tells what to plant and what to do in your central Florida garden in each month of the year. Written by Sydney Park Brown, and published by the UF Department of Environmental Horticulture, April 2012. http://edis.ifas.ufl.edu/ep450
			North Florida Gardening Calendar (ENH1190/EP451) Give cold-damaged palms proper care to encourage their recovery in February. In April, monitor landscape plants weekly for aphids on tender new growth. Annuals that can take full sun during hot summer months include celosia, portulaca, vinca, and some coleus. In September, plant cool-season vegetable crops, such as radish, carrot, cabbage, and lettuce. This 10-page fact sheet tells what to plant and what to do in your north Florida garden year-round. Written by Sydney Park Brown, and published by the UF Department of Environmental Horticulture, April 2012. http://edis.ifas.ufl.edu/ep451
		South Florida Gardening Calendar (ENH1191/EP452) Prune non-spring flowering shrubs and trees in January to improve form. In March, plant warm-season vegetables, such as sweet corn, cucumber, watermelon, and pepper, for late spring harvest. If bahiagrass lawns are yellowing in May, iron may correct the problem. Butterfly lily and gladiolus are bulbs that can be planted during the middle of summer. Plant gladiolus every 2 weeks in September to stagger blooming. This 11-page fact sheet tells what to plant and what to do in your south Florida garden, year-round.
