Excerpt From The Course


Approximately 100 genera and 2000species, herbaceous plants, shrubs and trees.

LEAVES mainly alternate.

FLOWERS are regular with 4‑5 petals and sepals, Stamens 5 too many borne on edge of calyx tube, ovary superior or inferior; fruit is a berry, pome or drupe.

Genera include: Cotoneaster, Cretagus, Cydonia, Eriobotrya, Filipendula, Fragaria, Geum, Kerria, Malus, Neillia, Photinia, Prunus, Pyracantha, Pyrus, Raphiolepis, Rubus, Sanguisorba (Burnet), Sorbus and Spiraea.


There are species and varieties of the genus "Rosa" which can be grown in almost any climate, provided the right type is chosen for the particular situation.  Most species tend to adapt better to cooler climates than to warmer climates.

Roses are broadly divided into the following groups:

BUSH ROSES: These grow into an upright bush up to about 2 metres tall.  The three main types are:  Hybrid Teas (give the biggest and best flowers), floribundas (greater quantity but less quality in the flowers, and grandifloras.  Some old world species are grown as bush types also, but these are less common.

STANDARD ROSES: These are budded onto long, single, upright stems giving the effect of the bush sitting high in the air on a pole.  Standard roses are anything from 1 to 3 metres tall.

RAMBLERS:  These are very vigorous, usually untidy growers which make a lot of new growth each year from the base.  They have large quantities of small flowers in bunches.

CLIMBING ROSES:  These have fewer basal shoots, larger flowers either individual or in small clusters, and solid, thick climbing stems.

MINIATURE ROSES:  Growing from 1 to 2 ft tall, stems are thinner and flowers are smaller than normal bush roses.  In affect, they appear as scaled down versions of the floribundas or hybrid teas.


*Roses prefer full sun for at least half of the day. As they have a shallow fibrous root system, avoid planting near large trees which have shallow spreading roots.

*Most soils, provided they are not waterlogged, are acceptable.  Roses tolerate a wide variety of soil types, but do prefer reasonable drainage.

*Watering is essential if a rose is to flower well.  Mulching can help.  Don't let them dry out.  It's better to make a dish in the soil at the base of a plant and fill it with water to allow slow penetration. You are better not to water the foliage.

*Roses do respond well to feeding.  Don't allow the roots to come in contact with strong (i.e. concentrated) fertiliser though as they will burn.  A slow release fertiliser or well rotted manure is best.

*Annual winter pruning is essential to both rejuvenate the plant and to encourage growth of young wood (flowers form on these young shoots; the more young shoots, the more flowers).  Usually (in temperate climates) at least half of the top growth is removed each winter.

Plants pruned regularly can last more than 100 years.

*Roses are largely sold bare rooted in winter.  You will buy the best selection of plants early winter when they are first released onto the market.

*Aphis and caterpillars are major problems.  They can be controlled with suitable insecticides Black spot, mildew and rust are common fungal problems fungicides are normally used to control these).

*In snow areas cut plants back very hard (i.e. 95%) and cover with straw over winter.

(NB: Roses are usually budded.  Do not cut below the bud).
