“Set It and Forget It” Hydroponic Lettuce

Hannah Eason

Florida ranks second in the United States for vegetable production, and the second largest industry in Florida is agriculture. However, the on-going loss of agricultural land to development, increasing labor costs, and decreasing water resources creates a need for alternative agricultural systems. Hydroponic food production can produce similar yields as traditional agriculture using less water, land, and labor. Equipping urban audiences with tools to grow food hydroponically provides new options for feeding the growing urban population in non-traditional environments. "Set it and forget it" hydroponics is a simple, affordable, and successful introductory hydroponic method. This technique is great for growers new and experienced and is especially well adapted for classroom experiments.

A Beginner’s Guide to Begonias: Hybridization and the Gateway to a New World in Its Breeding

Wisnu Ardi, Tao Jiang, andHeqiang Huo

Begonia spp. is one of the most diverse and popular ornamental plant groups, with over 2,000 species and hybrids valued for their foliage, flowers, and adaptability. Florida’s climate and horticultural industry make it a center for begonia production, yet practical guidance on hybridization remains limited. This publication provides a clear, step-by-step introduction to hybrid breeding for horticultural professionals, advanced gardeners, and researchers. Topics include basic genetics, selecting parent plants for desirable traits, pollination techniques to control crosses, and potential challenges. Methods for seed collection, germination, and hybrid evaluation are outlined with emphasis on assessing ornamental quality and stress resistance. Case studies from UF/IFAS breeding programs highlight successful crosses. This guide bridges science and practice to advance Begonia breeding for Florida and beyond.

S. H. Futch, C. C. Childers, and C. W. McCoy

A Guide to Identification of Soft-bodied Citrus Insect Pests

Stephen H. Futch, C. W. McCoy, J. P. Michaud, andC. C. Childers

Of the many Homoptera pests that infest citrus groves, only a few affect the health and productivity of a tree to a level where control measures are necessary. The first step in controlling any pest is correct identification. Without this, appropriate biological or chemical control measures cannot be selected. Inappropriate pest management tactics may fail to provide control of the target pest and/or disrupt existing natural control of other pests, leading to secondary pest problems. Most of the pests included in this article are under biological control by predators, parasites and pathogens, thus minimizing the need for pesticide applications.

A Guide to Scale Insect Identification

Stephen H. Futch, C. W. McCoy, andC. C. Childers

Control of scale insects in Florida citrus utilizes native and introduced exotic natural enemies, including predators, parasites, and pathogens. Under most conditions, predators and parasites suppress scale pest populations to a level where chemical intervention is unnecessary. In situations where natural enemies do not provide the necessary control, integrated pest management (IPM) is used since it minimizes negative effects on natural enemies. Increases in scale insect populations involve multiple factors including: a) disruption of biological control by weather; b) infestation of areas by scale insects where natural enemies do not exist; and c) disruption of natural enemies by the repeated use of non-selective pesticides.

A Guide to Soil Insect Pests Identification

Stephen H. Futch, C. W. McCoy, andH. N. Nigg

Soil provides a structure for a plant to anchor its roots and is a source of nutrition and water necessary for plant growth. Soil-inhabiting insects also utilize this substrate for part of or for their entire life. Although many insects are dependent on soil for food and shelter, only a few soil-borne insects such as weevils, ants, and termites are detrimental to the citrus tree.

A Practical Guide for Adjusting Fertigation Water pH in Specialty Crop Production

Guodong Liu, Md Jahidul Islam Shohag, Lisa Hickey, Yuncong Li, and Shufang Tian

Fruit and vegetable producers have widely adopted fertigation as a common practice. However, achieving optimal nutrient use efficiency and growth of crops requires careful management of the irrigation water’s pH, especially when the water quality exhibits excessive acidity or alkalinity. Adjusting the pH of irrigation water is crucial to meet crop preferences and ensure optimal conditions for growth. Growers frequently encounter challenges in effectively optimizing irrigation water pH. This publication aims to address this issue by providing an overview of adjusting irrigation water pH and offering practical guidelines. The target audiences of this guide are farm/nursery managers, growers, crop advisors, Future Farmers of America (FFA), Extension agents, researchers, students, and others who are interested in crop production.

A Step-by-Step Fertigation Guide for Blackberry Growers in Florida

Nurjahan Sriti, Elena Máximo-Salgado, Zhanao Deng, Jeffrey G. Williamson, andGuodong Liu

Blackberry cultivation offers significant opportunities for fruit producers in subtropical regions. Effective fertilizer management is essential for maximizing production. However, determining the optimal fertilizer application can be challenging as a result of variations in soil types and climate. To achieve the best results, it is important to follow the 5Rs of nutrient stewardship. (There are usually 4 Rs outside the unique environmental conditions of Florida.) These principles focus on applying the right fertilizer source at the right rate, at the right time, in the right place, and with the right irrigation. This guide provides Florida blackberry growers with practical recommendations for efficient fertigation practices to boost blackberry yields and improve nutrient use efficiency. It is intended for commercial growers, agricultural consultants, farm managers, Extension agents, Extension specialists, and others interested in blackberry production and sustainable farming.

Achachairu—a Potential Fruit Crop for Florida

Sergio Gutierrez, Tatiana Sanchez-Jones, Zhaohui Tong, andGuodong Liu

Garcinia humilis is an emerging tropical fruit crop in South Florida commonly known as achachairu. Achachairu has attracted much interest as a healthy fruit crop because it is rich in many nutrients such as foliate, vitamins, riboflavin, minerals, and antioxidants. The current use is limited and localized. To help Extension faculty, growers, and students better understand the potential of achachairu (Garcinia humilis (Vahl) CD Adam)  and Garcinia madruno as profitable crops and their health benefits, this publication is synthesized from literature sources and has been networked with farmers, food processors, chefs, and photographers. This document provides an overview of achachairu and ocoro (Garcinia madruno [Kunth] Hammel)—two common species in the Garcinia genus—including cultivation methods and use of the two crops grown in Florida.

Alleviating Astringency in Persimmon Fruit for Enhanced Palatability and Consumer Acceptability

Ali Sarkhosh, Fariborz Habibi, and Jeffrey K. Brecht

Persimmon fruits are classified as astringent or non-astringent, depending on the level of astringency the unripe or partially ripe fruit exhibit at the time of harvest. Astringency in persimmon fruit is a sensation caused by tannins present in the flesh that can make the mouth feel dry, cause puckering, numb the tongue, and constrict the throat. Sometimes, it may also impart a bitter taste. The astringency decreases as the fruit ripen until it is no longer present in fully ripe fruit. While consumers typically prefer non-astringent varieties, the cultivation of astringent varieties notably remains common. The purpose of this publication is to introduce consumers, growers, Extension agents, and specialists to postharvest methods for reducing astringency in unripe persimmons, making them more palatable and acceptable for consumption.
