Sexual propagation involves the union of the pollen (male) with the egg (female) to produce a seed. The seed is made up of three main parts: the outer seed coat, which protects the seed; a food reserve (e.g., the endosperm); and the embryo, which is the young plant itself. When a seed is mature and put in a favorable environment, it will germinate, or begin active growth. In the following section, seed germination and transplanting of seedswill be discussed.

La jardinería en macetas le permite tener y disfrutar de muchas plantas ornamentales y cuando no puede cultivarlas directamente en la tierra. Puede utilizar plantas cultivadas en macetas en entradas, patios, terrazas, azoteas, jardines, interiores o en cualquier lugar donde necesite añadir un componente vivo para mejorar el atractivo de una zona. Cada maceta plantada tendrá su propia personalidad; puede crear un paisaje en cada maceta. Pueden ser impresionantes o sutiles, grandes o pequeñas. Las plantas y las macetas ofrecen combinaciones ilimitadas de tamaño, color, forma y textura que pueden dar a su entorno interior y exterior un aspecto más agradable desde el punto de vista estético.

Water gardens require maintenance throughout the year. Preparation for the winter months is especially important for the survival of both the aquatic plants and the wildlife in and around the pond. Some plants will not tolerate winter weather and must be removed from the pond while cold-hardy plants need only to be completely immersed in the pond. Debris such as leaves and dying plants must be removed, especially if there are fish in the pond. Fall is the time to take action. Prepare the pond for the winter months by managing the plants, cleaning the pond, and monitoring the water conditions. If treated properly, many aquatic plants and wildlife can survive in the water garden for years.

Adequate soil moisture is essential for good crop growth. A healthy plant is 75 percent to 90 percent water. The plant needs that much water to carry out vital functions, including photosynthesis, support (rigidity), transpiration, and transportation of nutrients and sugars to various parts of the plant. During the first two weeks of growth, plants are becoming established and must have the proper amount of water to build their root systems. Too little water can stunt or even kill tender seedlings, while excessive moisture can prevent roots from moving out into the soil searching for water and nutrients. Without a sufficient root system, hot, dry weather can adversely affect vegetable plants as they mature. In areas prone to repeated drought, select drought-resistant varieties when buying seed or plants.

Mulching is a practice adaptable to nearly all home gardens. To mulch is simply to cover the soil around plants with a protective material, organic or inorganic.

El objetivo de la jardinería intensiva es cosechar la mayor cantidad posible de productos en un espacio limitado. Las huertas más tradicionales constan de largas hileras de hortalizas muy separadas entre sí. Gran parte de la superficie de la huerta está ocupada por el espacio entre las hileras. Una huerta intensiva minimiza el espacio desperdiciado. La práctica de la huerta intensiva no es solo para los que tienen un espacio limitado en el jardín; más bien, una huerta intensiva concentra sus esfuerzos de trabajo para crear un entorno ideal para las plantas, lo que brinda mejores rendimientos.

This extension publication discusses guidelines to quickly evaluate the performance of a sprayer. Sprayer calibration, nozzle discharge, spray pattern uniformity, speed checks, pump performance, and plumbing arrangements are evaluated with minimal calculations.

This publication explains how to obtain representative soil samples and to submit them for analysis to the Virginia Tech Soil Testing Laboratory.

The goal of this training guide is to reduce the number of accidents and related injuries among the youth workers in the green industry by making workplaces safer. This guide is primarily for employers or supervisors of youth workers in the green industry. In addition to familiarizing the employers/supervisors with the regulations associated with hiring youth workers, the guide discusses the steps they can take to make their work environments safer. It also covers the responsibilities of guardians and youth workers for making workplaces safer.

Many hand tools such as rakes, shovels, and pruners are used widely in lawn care operations. While these non-powered tools are not known to cause major injuries, they have the potential for injuries that may require absence from work and/or medical assistance when they are used improperly.
