A glossary of common garden terms.
Every gardener and nurseryman will come accross gardening terminology in books and even on television shows, sometimes a little obscure. We look at some of the most common garden terms and explain them.
Acid soil (see soil ph)
Any soil with a pH lower than 7.0 is considered an acid soil.
Alkaline soil (see soil ph)
Any soil with a pH higher than 7.0 is considered an alkaline soil.
Plant propagation by scaring the stem of a plant, wrapping in peat moss or similar and waiting for new roots to form. The stem is then cut and planted.
Annuals are plants that live for just one year and then die after flowering.

Removing spent flower heads from plants to improve appearance and encourage new growth.
A plant that drops its leaves in Autumn and grows new foliage in spring.
Removing side buds or smaller buds to encourage larger blooms in a main flower. Often associated with Dahlias and Chrysanthemums grown for exhibition

pH Soil pH
pH is a measure of the acidity. In gardening pH is a measure of the amount of calcium in soil. pH is measured with a pH meter. Some plants prefer high acidity and others low acidity. Acidity is adjusted (lowered) by the addition of lime to the soil. Sulphur may be added to raise the acidity of soil.
Potting on (Potting up)
Removing a plant from a small container and placing it in a larger container to allow for growth
When the roots of a plant completely fill a pot, they circle aroun d the inside of the pot and form a tight ball.Rots may begin to grow though the holes in the bottom of the pot. (time to pot up)
Cutting back the growth on any plant for cosmetic, height reduction or plant health reasons.
Transplanting seedlings from where they germinated to individual or larger pots or trays
