Use this Glossary to get quick definitions or explanations of terms and concepts used in this collection—or terms that you might encounter while managing your own peach trees.
Galaxy: This unique freestone variety is often called the bagel peach or donut peach because of its size and shape. Galaxy peaches are prized for their deliciously sweet, tender white flesh.
Grafted: Peach trees that are created by grafting branches of the desired variety onto the rootstock of a particularly vigorous variety. Most peach trees you buy at garden centers or online are grafted.
Hale Haven: This is a very sweet variety that produces medium- to large-sized freestone peaches in midseason. Hale Haven peaches are excellent for free eating but are also considered one of the best canning peaches.
Harmony/Canadian Harmony: This is a vigorous, cold hardy variety that is also moderately resistant to bacterial leaf spot. Harmony produces medium to large freestone peaches that have a long shelf life and freeze well.
Babe: This dwarf tree is typically only 5 feet tall and no wider, making it perfect for container gardening. In addition to fresh eating, you can use these freestone peaches in cooking and baking, and for preserves or canning.
Nectar: This prolific variety produces a juicy, aromatic, white-fleshed freestone peach. Nectar peach trees tend to be fairly tall, although there are semi-dwarf trees available.
O’Henry: These freestone peaches are ready to harvest in late-summer and are widely regarded for their firm yellow flesh and thin red skin. O’Henry peaches are a good choice to use in mixed drinks, sorbets, and preserves.
Pix-Zee: This is a dwarf peach that’s ideal for container growing. Pix-Zee produces large yellow freestone fruit that ripens early in the season.
Haven: This is the most popular variety and is the standard for early peaches. Red Haven is a vigorous tree, bearing medium-sized fruit with firm, red skin. It is excellent for canning, freezing, and fresh eating.
Reliance: This is a hardy variety that can bear fruit as far north as Canada, so it’s the best choice for climates having severe cold in winter and spring. Reliance is known for its showy bloom and produces small to medium-sized, soft fruits early in the season.
Scaffold: Branches that grow laterally around the trunk of a peach tree that you’ll use as the basis for a bowl or vase shape when you prune your peach tree.
General gardening terms:
Antioxidant: A substance that inhibits damage to the body caused by the release of free radicals. The anthocyanin in blueberries is considered a powerful antioxidant.
Bacillus thuringiensis: A natural pesticide useful against a number of pests. BT is common soil bacteria that have been used as microbial insecticides for the last century. They can be used on foliage, food storage facilities, soil, or water environments. BT occur naturally, affect very specific insects, and are relatively inexpensive and safe for humans, birds, fish, and most beneficial insects. However, for them to work effectively, you need to know what type of insect you want to target and make sure that you buy a strain that will kill that particular species.
Biennial: Plants that form leaves in the first growing season, and flowers and seeds in the second growing season. After that, the plants die.
Brassicas: A genus of plants in the mustard family that includes cabbage, broccoli, Brussels sprouts, cauliflower, kale, and mustard—foods rich in vitamins and minerals.
Borage: A plant with blue flowers that grows wild in some areas. Its leaves, flowers, and stalks are edible and taste a little like cucumber. Borage leaves are good in salads, yogurt, or cream cheese mixtures, or go well when served with shellfish.
Cultivar: A cultivated variety of a plant produced by selective breeding. A cultivar may not produce true-to-seed. Growers who want to retain the characteristics of a cultivar in future plantings should propagate new plantings from cuttings.
Cultural care: Good cultural practices include providing plants the best possible growing situation: proper spacing, watering, staking or trellising, sanitation, mulching, fertilization and general maintenance practices.
Dormant: This is the period of time when a fruit tree’s buds are relatively inactive. This is also called the overwintering stage.
Extension service: A service that extends information to users including farmers, growers, and homeowners. The Cooperative Extension Service (CES) is a publicly funded research and education network linking the resources of federal (U.S. Department of Agriculture), state (land-grant universities), and local (county) governments. Google “extension service” to find your local service.
Free radical: An especially reactive atom or group of atoms with one or more unpaired electrons. Free radicals produced in the body by biological processes (breathing, digesting, exercising) or from the environment (tobacco smoke, toxins, pollutants) can cause damage to cells, proteins, and DNA by changing their chemical structure.
Fungicide: A specific type of pesticide that controls fungal disease by specifically inhibiting or killing the fungus causing the disease.
Grafting: This is a horticultural technique used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant.
Hod: A portable trough, often used for carrying gardening supplies and materials around your garden.
Horticultural oil: An oil-based pesticide mixed with water that is made of some type of mineral or vegetable oil and is safe for use on food crops
Nasturtiums: A genus of about 80 species of annual and perennial herbaceous flowering plants that are often used as edible and decorate items in culinary dishes. Nasturtiums are sometimes used as companion plants for biological pest control, repelling some pests, acting as a trap crop for others and attracting predatory insects. Nasturtium plant varieties include Alaska, Black Velvet, Empress of India, Orchid Flame, and Purple Emperor.
Neem oil: A naturally occurring pesticide found in seeds from the neem tree. It is yellow to brown, has a bitter taste, and a garlic/sulfur smell. It has been used for hundreds of years to control pests and diseases.
NPK: The three numbers on fertilizer represent the percentage of nitrogen (N), phosphorus (P), and potassium (K) that compose complete fertilizers.
Perennial: Plants that grow for more than two growing seasons.
Perlite: An amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. When in pebble-like form and mixing with gardening soil, perlite makes for a great aerating and moisturizing agent, as well as providing well-drained soil.
Plug: A section of a plant cut out using a circular tool like a golf hole cutter or a bulb planter. This gives you a cutting of the plant that includes part of the root system. Most commonly used with wild lowbush blueberry plants.
Pollination: The process of transferring pollen from the male part of flowers (anthers) to the female part of the flowers (stigma). Pollination is most often accomplished by insects—primarily bees.
Propagation: The process which grows new plants from a variety of sources, such as seeds, cuttings, and other plant parts
Pyrethrin: Pyrethrins are a class of organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity by targeting the nervous systems of insects.
Rhizome: An underground runner or stem of a plant that stores extra nutrients and eventually develops roots and stems identical to its parent plant. This allows the plant to spread out.
Self-fertile, Self-fruitful, self-pollinating: Plants that do not need pollinators in order to reproduce. Self-pollinating plants have flowers with both male and female parts.
Self-sterile: A plant that needs a second plant of a different variety with which to cross-pollinate.
Soil pH: A measure of the acidic or basic (alkaline) level of soil. Blueberry plants require acidic soil in order to thrive; a pH of 4.0 to 4.8 is ideal for blueberry plants. A neutral pH (neither acidic nor alkaline) is 7 on a 14-point scale.
Soilless growing medium: Common soilless growing mediums include peat moss, perlite, vermiculite, and sand.
Spade fork: A gardening tool that looks like a broad-tined, short pitchfork; used to turn soil and mix with compost and other soil mixes.
Spinosad: A natural substance made by a soil bacterium that can be toxic to insects. It is used to control a wide variety of pests including thrips, leafminers, spider mites, mosquitoes, ants, fruit flies, and others.
USDA Plant Hardiness Zones: The standard by which gardeners and growers can determine which plants are most likely to thrive at a location. USDA has a zoned map, based on the average annual minimum winter temperature, divided into 10-degree Fahrenheit zones.
Variety: A group of plants selected for particular characteristics and which usually produces true-to-seed.
Widger: A spatula-like gardening tool for lifting plant seedlings without damaging them.
