El higo (Ficus carica L; familia Moracea) se originó en los trópicos del Viejo Mundo: Asia Menor y la Región Mediterránea. En el Mediterráneo, el higo se ha cultivado desde el año 5,000 a.C. Muchos cultivares de higos fueron importados del Viejo Mundo en los últimos 50 años. Actualmente, sin embargo, no hay programas de mejoramiento de higos en los Estados Unidos, y de entre al menos 60-100 cultivares de higos nombrados, relativamente pocos se cultivan en el sureste de los Estados Unidos.

Japanese persimmons were first grown in Florida in the 1870s, but as of 2017, most US plantings are on a small scale; however, even as the overall acreage has decreased, the number of farms in Florida growing the fruit increased from 2012 to 2017. Trees grow and fruit best in central and northern Florida and can produce high yields of good-quality fruit. With an estimated population of more than 21 million, a diverse cultural base, and large cities close to production zones, Florida is primed for a larger persimmon industry. This 11-page revision provides growers with a primer on persimmon characteristics, marketing, and cultivars. Written by Ali Sarkhosh, Peter C. Andersen, and Dustin M. Huff, and published by the UF/IFAS Horticultural Sciences Department.
Dragon fruit, also known as pitahaya, pitaya, and strawberry pear, is a group of vine-like, climbing cacti. In south Florida, production of dragon fruit has been steadily increasing since the 2000s, and growers in Florida consider dragon fruit as a potential alternative fruit crop to avocado and citrus, two economically important fruit crops largely impacted by laurel wilt and huanglongbing, respectively. This new 4-page article focuses on the symptomology and epidemiology of stem and fruit canker, a prevailing disease on dragon fruit. Suggested management strategies for the disease are also discussed based on recent studies conducted in south Florida. Written by Cheng-Fang Hong, Shouan Zhang, Romina Gazis, Jonathan H. Crane, and Jeff Wasielewski, and published by the UF/IFAS Plant Pathology Department.
Hops (Humulus lupulus L.) are an essential ingredient in brewing, adding bitterness and flavor to beer. Driven by the recent craft beer movement, hop production is expanding into nontraditional hop-producing states. In Florida, while commercial hop production is almost nonexistent, the number of craft breweries in Florida increased from 45 in 2011 to 285 in 2018, and the economic impact of Florida’s craft beer industry exceeds $3 billion. This new 7-page article, written by Shinsuke Agehara, Aleyda Acosta-Rangel, Zhanao Deng, Jack Rechcigl, and Simon Bollin and published by the UF/IFAS Horticultural Sciences Department, provides guidelines and considerations for building a hop yard in Florida, using the UF/IFAS Gulf Coast Research and Education Center’s research hop yard as a model.

Blackberry (Rubus spp.) is a deciduous berry crop and the fourth most economically important berry crop in the United States. Driven by the growing demand for blackberries, production recently expanded to the southeastern United States. In Florida, however, commercial blackberry production is limited primarily to small commercial U-pick operations. The main challenges include insufficient chill hours and poor fruit quality associated with the subtropical climate. This new 6-page article, a publication of the UF/IFAS Horticultural Sciences Department, will discuss important cultivar selection criteria and recommended blackberry cultivars in subtropical Florida. Written by Shinsuke Agehara, Syuan-You Lin, and Zhanao Deng.
Hops (Humulus lupulus) are perennial plants commonly harvested for their mature strobiles, also referred to as cones, which are primarily dried and used as a bittering agent and preservative in beer production. The two primary factors of harvest timing and harvest method can have large impacts on the quality and economics of the finished product. The decision of when and how to harvest is important and should rely upon growing-region-specific environmental conditions, physical observations of the cones, and the wants and needs of the individual producer. This new 4-page publication of the UF/IFAS Environmental Horticulture Department describes the primary methods used in hop harvesting, including field, indoor, and machine harvesting. Written by Sean Michael Campbell and Brian J. Pearson.

Propagation is an important technique used by tropical and subtropical fruit growers worldwide, allowing plants to be grown cheaply and efficiently. While sexual propagation (by seed) results in plants that are not genetically the same as the mother plant, asexual propagation (cuttings, division, air-layers, and grafting) creates offspring that are clones of the mother plant. Cloning fruit trees is important because it allows different cultivars to be preserved over time. This new 7-page publication of the UF/IFAS Horticultural Sciences Department explains both sexual and asexual propagation techniques, why they are used, and what type of propagation is best for which species of tropical fruit. Written by Jeff Wasielewski and Carlos Balerdi.

Weeds are a major contributor to yield loss and reduction in yield quality in an agricultural setting, competing with the crop for resources like light, water, and nutrients. This competition, along with the cost of weed management strategies like tillage and herbicides, is responsible for the economic impact of weeds, which can reach into the billions. Weeds can also harm crop plants by acting as reservoirs for destructive plant pathogens, the insect vectors that move these pathogens from plant to plant, or both. This new 7-page publication of the UF/IFAS Horticultural Sciences Department, written by Morgan Byron, Danielle Treadwell, and Peter Dittmar, summarizes previously published weed-pathogen associations to help growers scout and monitor pathogens in weeds near production areas.
