What's in a Name

Experienced gardeners don’t have a problem with horticultural terms, but when someone is fairly new to the pastime, constant use of binomial nomenclature will soon have them throwing the rake and shovel back in the shed and turning to extreme sports as a hobby, maybe alligator wrestling or even bowling.

It doesn’t hurt to pick up a few terms, though, if only to avoid stomping on your best cookware when someone suggests breaking up the hard pan in your backyard. And, you’ll feel much less intimidated around the garden centre when asked if you’d prefer bare root to B and B, which might be misinterpreted as a vague proposition.

Accent Plant — A focal point plant, a plant to catch attention. Principal plant used to anchor a grouping. Usually the one you spent the most money on.

Aerate — Loosening or puncturing the soil to increase water penetration and allow oxygen to reach plant roots. Worms will do a very good job of this if you let them.

Air Layering — A specialized method of plant propagation accomplished by cutting into the bark of the plant to induce new roots to form

Alkaline soil — A soil with a pH higher than 7.0 is an alkaline soil, whereas a soil pH lower than 7.0 is acidic. Many plants have a distinct preference.

B and B — Trees or shrubs that are sold with the roots balled and burlapped as opposed to bare root or potted up.

Bedding plant — Mainly annuals. Quick, colourful flowers, typically used for mass planting in public gardens.

Biennial — A plant that grows the first year, flowers the second, then sets seed and dies — hollyhocks, for instance. However, the flowering sequence of a clump of biennials will eventually overlap and will appear to flower every year as though they were perennials. 

Bolting — Vegetables which quickly go to flower rather than producing the food crop. Usually caused by late planting and excessive heat. Common with lettuce in summer.

Bracts — Modified leaves growing just below a flower. These are often confused with the flower itself. Typical is that red and green Christmas thing.

Cambium — The thin membrane located just beneath surface of stems and beneath the bark on trees. It's where cells originate, producing growth.

Cotyledon — The first set of leaves to grow after a seed has germinated. Use these as handles when it’s time to transplant.

Damping off  — A fungus, and something to think about when you begin starting seeds. It usually affects seedlings and causes the stem to rot off at soil level. Use sterilized potting soil and careful sanitation practices to prevent this.

Dead head — The process of pinching off used or spent blooms to keep plants well groomed and discourage them from setting seed. Promotes continued bloom. Not necessary on plants like impatience, but recommended for regular petunias.

Dibble — A pointed tool used to make holes in the soil for seeds, bulbs, or young plants.

Double flower — Not two flower heads but a flower with many overlapping petals that gives a very full appearance.

Drip line — The line below the tips of the outermost branches of a tree or plant. It’s the place to water the tree, not the branches as I often see being done (okay, maybe he was washing the leaves).

Espalier — The process of training a tree or shrub so its branches grow in a flat pattern against a wall or trellis. Very useful for growing fruit trees in a confined area.

Friable — loose, crumbly soil.

Flat — A shallow box or tray used to start cuttings or seedlings.

Foliar feeding — Spraying foliage with a liquid fertilizer. Better to feed the roots.

Girdling — The choking of a branch by a wire or other material, most often in the stems of woody plants that have been tied to tightly to a stake or support.

Hard pan — The impervious layer of soil or clay lying beneath the topsoil

Heeling in — Temporarily setting a plant into a shallow trench and covering the roots with soil to provide protection until it is ready to be permanently planted.

Herbaceous perennial — A plant with soft rather than woody stems that die to the ground in winter.

Humus — The brown or black organic part of the soil resulting from the partial decay of leaves and other matter (definitely not to be confused with hummus).

Loam — A rich soil consisting of a well- balanced mixture of sand, clay, and decaying organic materials.

Microorganisms — Animals and plants that are too small to be seen clearly with the naked eye but are essential in healthy soil.

Node — The part of a stem from which a leaf or new branch starts to grow.

Pinching back — Using the thumb and forefinger to nip back the very tip of a branch or stem. Pinching promotes branching, and a bushier, fuller plant.

Perennial — A non woody plant which grows and lives for more than two years. Perennials usually produce one flower crop each year, lasting anywhere from a week to a month or longer. Conversely, annuals go from seed to bloom to seed in one season.

Scarify — To scratch or break the hard coat of some seeds, so that they’ll germinate easily. Fine sandpaper or just soaking the seed will do the trick.

Sucker — Growth originating from the rootstock of a grafted plant, rather than the desired part of the plant. Sucker growth should be removed, so that it doesn't draw energy from the plant.

Trug — A shallow basket for light chores, like carrying flowers and fruits and veggies. Traditionally made of wood. Very functional.

Variegated leaf — A green leaf with differently coloured zones in the leaves. Blotched or edged, typical in hostas. 

Xeriscape — This is a name of a landscaping method based using drought tolerant plants in areas with little water.

There you go, just a few words and expressions used to describe things in or around the garden and keep you out of trouble. If you need more, just ask. That’s the easiest way to pick up garden lingo.
