A plant that completes its entire life cycle (growth, reproduction, death) in one season.
These plants have been field-grown and are supplied in a dormant state with the soil removed.
A plant that completes its entire life cycle in two years, growing in the first year and reproducing and dying in the second.
To flower and produce seed prematurely.
Refers to the point at which the plant has been grafted on to a rootstock and is usually found at soil level. This is the result of a technique called ‘budding’ where the bud of one plant is grafted on to another plant.
An underground storage organ with fleshy scale leaves from which the plant flowers and grows before becoming dormant.
The stems of a raspberry or blackberry plant. Raspberry plants are supplied as dormant canes.
Placing seed potatoes in a tray or egg box in a bright, cool but frost-free place to encourage them to sprout prior to planting.
Structure made of glass, plastic or horticultural fleece placed over a plant for protection or for forcing early crops.
Unheated frame for growing on and acclimatising hardy and half-hardy plants outdoors.
A plant carefully trained to grow as one main stem, or occasionally two or three main stems, by removing side-shoots.
A rounded underground storage organ, consisting of the stem base, and often with a fibrous outer layer. It is replaced by the plant annually.
The growing point of a plant from which new shoots emerge, at or just below the soil surface.
A plant that is bred or selected by growers for unique flowers, leaf colour, growing habit etc. It has distinct and uniform characteristics that differ from the original species.
To remove the spent blooms on a plant to encourage further flowering or to prevent self-seeding.
A plant that sheds its leaves each year.
To sow seeds outdoors in their final positions, where you would like them to flower or crop.
To draw soil up around a plant to exclude light, protect from frost or encourage roots to develop from the stem.
Used to describe plants that like acid soil and will not tolerate alkaline soils (containing lime or chalk).
Refers to strawberry varieties that yield a small crop in early summer, a few berries throughout the rest of the summer, and another heavier crop during late summer and early autumn.
First generation offspring derived from breeding two distinct pure-bred lines. They are vigorous and uniform plants. Seeds produced from F1 Hybrids will not come true to their parents.
A one-year old tree with several side branches (feathers).
First Early Potatoes
These are harvested 10 weeks after planting and will produce new or baby potatoes.
Refers to raspberry and blackberry stems that grow for one year before bearing fruit and flowers e.g. summer-fruiting raspberries and blackberries.
Refers to the point at which a seed undergoes physical changes and begins to grow.
Where one plant is artificially joined to the rootstock of another so they eventually function as one plant.
Plants that are sown in early spring and given protection. Most half-hardy annuals are frost-tender and must not be planted outdoors until all danger of frost has passed.
A plant that lives for more than two years. They cannot tolerate heavy frost (temperatures below 0oC) but may be over-wintered if given frost protection.
To acclimatise young plants that are growing in a protective environment, to cooler conditions outdoors. This is normally achieved by leaving plants outside during the day and bringing them undercover at night.
Hardy plants that do not need to be raised indoors but can be sown directly into their flowering positions in the garden in spring.
A plant that lives for more than two years and is fully hardy.
Another name for the leaves and stems of a potato plant.
A non-woody perennial plant, often dying back in the winter and becoming dormant by means of underground rootstocks or a woody base. Growth resumes in the spring.
Calcium compounds, often applied to lower the pH of the soil (make it more alkaline); particularly useful when growing brassicas (cabbages, broccoli etc) to prevent club root disease.
These are raspberry canes which are supplied at a more mature stage of their life and will produce fruit in their first season. The canes supplied are longer than usual (1.25-1.4m).
A young tree, generally less than a year old, that can be trained into any form required.
These are harvested up to 20 weeks after planting and are good for winter storage. They are good for baking, roasting and mashing.
Layer of material placed on the soil and around plants to retain moisture, suppress weeds and improve soil structure. Materials used for mulching include well-rotted manure, compost, polythene sheets or gravel.
Substance of animal or plant origin – such as compost, leaf mould or manure. Useful for improving soil structure and supplying nutrients to plants.
Removing the growing points of a young plant to encourage side-shoots to form. This encourages a bushy habit and more flowering stems.
The transfer of pollen between flowers, which can be carried out by the wind, insects, animals or by hand.
To remove a plant from its container (normally when it has outgrown the space) and place it into a new container for further growth.
To place seedlings and cuttings into containers to grow on.
To remove and transfer seedlings into pots or module trays to give them more space to grow.
Refers to the first-year stems of raspberries and blackberries. Autumn-fruiting raspberries will produce flowers and fruit on primocanes (they produce fruit in their first year of growth).
To grow plants from seed or by vegetative means e.g. cuttings or grafting.
A horizontal fleshy stem which grows at or below ground level. Rhizomes produce roots and shoots.
The underground part of a plant containing the roots. In grafting, a plant (scion) is joined to a desirable rootstock – often to promote a dwarfing habit.
The end of a seed potato with the most eyes – often the widest end. Potatoes should be chitted with the rose end facing upwards.
A trailing stem growing above ground and rooting at the nodes, where plantlets are produced. Some plants produce underground runners.
Second cropping potatoes
These are planted in late summer/early autumn and harvested about 14 weeks after planting, as for second earlies.
Second early potatoes
These are harvested about 14 weeks after planting. They make excellent salad potatoes and many varieties are also good for chips, roasting and mashing.
A potato tuber grown specifically for starting new plants and producing potatoes.
A plant that does not need pollen from a second individual in order to fertilise and set fruit.
A plant that retains most or some of its foliage throughout the year.
Cuttings taken from a mature Sweet Potato plant.
Normally a tree or shrub grown in a prominent position where it can be viewed from different angles.
A tree or shrub that has been trained to a certain height with a long bare stem and foliage at the top.
A plant that lives for more than two years. They cannot tolerate any frost and should be kept at temperatures above 5oC all year round.
To remove a number of buds, flowers, seedlings or shoots to improve the growth and quality of those remaining.
Swollen root or underground stem with storage tissue.
