Sorghum Silage as a Feed Alternative for Backgrounding Heifers in Florida

Federico Tarnonsky, Federico Podversich, Araceli Maderal, and Nicolas DiLorenzo

Sorghum has been gaining attention in Florida as a crop alternative harvested as whole plant silage for inclusion in backgrounding diets as the main roughage source to fill the forage gap in winter feeding programs. The objective of this publication is to share the experience of three consecutive years at the North Florida Research and Education Center (NFREC) in Marianna, Florida, using whole-plant sorghum (Sorghum bicolor) silage as the main dietary ingredient for growing heifers. County Extension agents and cattle producers can use this report to reference a range of expected weight gains, feed conversion rates, and costs when using sorghum silage as the main dietary ingredient in backgrounding beef cattle diets. Adopting this technology could increase the opportunity for producers to add value to weaned calves across Florida, where there are suitable conditions for growing sorghum.

How to Identify and Propagate Different Types of Wild Coffee for Your Florida Garden

Teagan Young and Sandra B. Wilson

Rubiaceae, a family known for its economic and ornamental significance, includes several native Florida species, such as wild coffee (Psychotria spp.). This publication focuses on identifying and propagating wild coffee species: P. nervosa, P. nervosa 'Little Psycho', P. nervosa 'Turtle Mound', P. tenuifolia, and P. ligustrifolia. These species thrive in various soil conditions and attract pollinators, making them valuable, adaptable, and appealing for sustainable landscapes and Florida gardens. Research on propagation methods revealed that while physiological dormancy makes seed germination challenging, softwood cuttings treated with indole-3-butyric acid (IBA) showed high success rates in rooting. The publication outlines a production schedule, recommending specific substrates and misting techniques to optimize root development. It provides critical insights into enhancing the availability and cultivation of wild coffee species, promoting their use in Florida-friendly landscapes.

Balancing Pest Management and Insect Conservation on Ornamental Plants

Bernadette Mach, Jaret Daniels, and Adam Dale

Increasing public awareness of the dangers of declines in biodiversity has generated unprecedented interest in promoting beneficial insects and other wildlife in yards and gardens. Research shows that well-managed urban landscapes can support diverse wildlife and that many people want their yards to support insect conservation. The green industry has made efforts to align plant production practices, marketing, and landscape maintenance with consumer conservation goals. However, backyard conservation efforts can be hindered by insect pest outbreaks. These are often more frequent and severe in urban landscapes than in rural or natural areas because of environmental constraints. Invasive pest species may thrive unchecked and require intervention. People may face difficult decisions when trying to balance conservation goals with pest management and plant health needs. This publication explains the ornamental plant pest management process with an emphasis on protecting beneficial wildlife.

Pseudophoenix sargentii: Buccaneer Palm

Mica McMillan and Kara McCoy

This publication is intended for anyone interested in identifying and utilizing this Florida native palm in their landscape. Pseudophoenix sargentii is native to the Caribbean, Belize, Mexico (Quintiana Roo), and Navassa Island. This palm is widely adapted to south Florida soils, is salt tolerant, and grows well in full sunlight. As an attractive palm with blue-gray fronds and an erect trunk, this palm would make a beautiful addition to any landscape, but its slow growth and lack of cold tolerance have prevented it from being widely utilized in Florida landscapes.

Passion Fruit Propagation: A Comprehensive Guide

Ali Sarkhosh, Juan David Jimenez Pardo, Jonathan Clavijo-Herrera, Uzman Khalil, and Jonathan H. Crane

The climate of Florida is suitable for growing a variety of tropical and subtropical fruits, including passionfruit (Passiflora edulis). Passionfruit has a distinctive aroma and sweet-sour taste, and it has become highly appreciated in culinary and home gardening circles. The center of origin of passionfruit is South America, although it is also grown in other tropical and subtropical regions around the world. The cultivation of this fruit requires a solid understanding of effective propagation methods to ensure the availability of high-quality plant material. This guide covers various sexual and asexual propagation techniques, from traditional seed sowing to advanced methods such as tissue culture.

Lesion Mimics in Mule Palm (× Butyagrus nabonnandii)

Braham Dhillon, Lucas Altarugio, Seemanti Chakrabarti, and Kamaldeep Bansal

Palms (Arecaceae) are flowering plants with varied growth forms ranging from climbers to tree-like plants found across diverse habitats. Some palm species naturally hybridize with other species, whereas a few species can be artificially hybridized to produce new morphotypes. Mule palm (× Butyagrus nabonnandii) is an artificial hybrid that is becoming popular as a landscape ornamental because of its appearance and cold hardiness. However, hybridization among different species could lead to unintended outcomes, including lesion mimics. A lesion mimic phenotype was identified in mule palms growing across multiple farms across central and south Florida. As leaf spots are one of the most common symptoms observed during disease or nutritional deficiency, the detection of lesion mimics can sometimes be challenging. This publication documents a simple method to identify lesion mimics in palms. Correct diagnosis of lesion mimics would limit unnecessary applications of fungicides or fertilizers.
