True alpines are classed by botanists as plants which grow between the permanent snow line and the limit of conifer tree growth. Around the world the equivalent of this area is found at sea level regions and above 6000 feet in other parts. Alpine plants are adaptable for survival in extreme conditions.
For many months of the year the alpine plants are protected by a deep layer of crisp snow which keeps them dry and at a constant, low temperature, but not nearly as low as the air temperature above the snow. In spring these alpine plants receive copious amounts of moisture as the snow melts and they make rapid growth.
Alpine plants need a well drained soil and are usually planted on rockeries, mounds or in walls, Another point to remember is that some alpines are lime-haters and will perish where lime is present.
There are many varieties of plants that are used as alpines, which originate from dwarf hardy perennials, these are usually easier to grow and do not need such specialist conditions as the true alpines while still give an extremely good show of colour.
To ensure that alpine plants will flourish in your garden it is obvious that you must do your best to provide conditions like good drainage, a fertile but not too rich soil as all these plants need only the minimum amount of nutrients. Alpines can also be grown in pans in a cold greenhouse or planted out in a specially built alpine cold frame.
Another method of growing alpines is to use a specially built alpine greenhouse, where the plants are grown on benches. Growing alpines in this way you can give each variety separate cultural needs, but the greenhouse MUST be very well ventilated by using not only roof ventilators but side louvre vents every 2ft. or so along the side of your greenhouse, these are usually placed just above the bench if you are growing on benches, or at ground level if growing on the floor of your greenhouse. Shading of the alpine house will be necessary during the hot spring, summer and autumn days.
Using a greenhouse to grow alpines, is quite a different purpose from most other types of greenhouse plants, because all you are doing is protecting the alpines from the extremes of the British weather. As mentioned above, if all you want is some dwarf alpine plants for you boarders, then the hardy perennial type of Alpine Plug Plants could well suffice, these are offered in a wide variety and colour range.


Perennial plants have gained popularity, over the annual bedding plants, because of their low maintenance and not needing to be re-planted every year. Perennial plants are grown from seed, cuttings and splits and cover a large number of species, many now being introduced from other countries such as Australia , New Zealand , Japan and China.
Planting perennial plants:
Dig the hole larger and deeper than the root ball of the perennial, loosen the bottom of the hole with a trowel, then, after gently loosening the roots in the root ball, fill the soil in around the plant and gently firm. If you do not have access to well rotted manure, then peat or bark will do the job nicely. Fortunately, the vast majority of perennials that are more widely grown are very accommodating. They will thrive in most types of soil although characteristics such as, vigor and rate of growth will vary considerably from variety to variety, and also from different types of soil.
You must never coddle hardy perennial plants, as they are on the whole very hardy and resent being grown soft.
The taller varieties of perennials will need staking and tying, if you want to get the best effect from them, also watch out for creeping weeds such as bindweed, which, if left unchecked will chock your plants. In the late autumn when the perennials have finished flowering, most will need to be cut down to ground level with the exception of as few varieties, e.g. Penstemons must not be cut down until they start to show new shoots in the spring, then you should cut them down to ground level to allow the new shoots to come up from the crown off the plant. The best thing is to consult any good gardening book, and this should tell you the varieties to cut and those not to cut down.
Why cut back perennial flowers?
Cutting back flowering hardy perennials will help to improve and prolong flowering and the shape of a plant. Flowering perennials will make more flowers, better quality blooms or bushier plants after being trimmed to shape, this also promotes more and larger flowers.
Other ways to promote better flowering:
Most flowers bloom and set seed which is a natural climax to the annual growth cycle. By deadheading flowers as they fade not only makes the plant look tidy, but also interrupts the plants sequence and stimulates new flowers to appear. Deadhead fading flowers of herbaceous perennials regularly as this will stimulate new flowers and prevent plants from self-seeding. Most hardy perennials should have their dead flower stalks cut back to the nearest bud at the base of the flowering stem as soon as the flowers begin to fade. By using this technique it also prevents unwanted self-seeding. You can either use your thumb and forefinger, garden cutters or secateurs Some hardy perennials concentrate their energy into a single tip bud. If you remove this tip bud then the buds lower down will produce side shoots. This is called stopping, pinching or tip pruning and makes bushier growth. Some plants will only need pinching once, other perennials may need pinching a few times by taking out the initial bud and then pinch out the resulting side growths. By chopping back hardy perennials in the late-spring this will make bushier plants that will flower later in the season very often more prolifically. This pinching back is best carried out in late May early June, and is done by cutting or pinch back the plants by half their length. You will need to watch out for Aphids, Caterpillars and the like during the summer months.


A herb garden is a favorite way of assembling herbs plants and examples can be seen in many Botanical gardens and at Historical houses throughout the British Isles. Mostly, the average gardener only grows the herb varieties he or she likes for their own consumption or decoration.
Herbs fall mostly into two distinctive groups, culinary and aromatic, although as in most things there are the exceptions to the rule, one that comes to mind is the Lavender, this is usually used for its perfume but can be used to flavor scones, cakes etc. The foliage of herbs are used both in the 'green' state and dried, incorporated into food or just sprinkled over dished.
Some of the more popular types of herbs are Sage, Thyme, Rosemary, Garlic, Mint, Coriander, Balm, Oregano, Feverfew and of course Lavender. Herbs plug plants can be planted from spring through to autumn, and are mostly sold in containers or as herb plugs, for potting on into pots or herb bowls for, display or use in the kitchen as fresh herbs, or planted out into the garden. Insect Control
Some common herbs show promise as an environmentally-friendly alternative to conventional pesticides. Research work has been carried out on the insecticidal properties of rosemary, thyme, clove and mint. These varieties and others could become a key weapon against insect pests in organic agriculture.
Many plants essential oils have a broad range of action against bugs; some will kill them outright others act as a repellent. The oils from these plants are generally a mixture of small quantities of several different herbs diluted in water.
Conventional pesticides need approval before they can be used; these only need more limited approval from regulatory bodies and are readily available.
Another advantage is that insects are less likely to become resistance and safer to use.
These oils tend to evaporate quickly and degrade rapidly in sunlight, growers and gardeners will need to apply them more frequently than conventional pesticides. Being less potent than conventional pesticides, applications at a higher concentration will be necessary to achieve acceptable levels of pest control. Research is now under way to make these new pesticides longer-lasting and more potent.
At the moment conventional pesticides are still the most effective way to control many pests although we have found that since we started using ‘Compost Tea’ we have reduced our need to use pesticides by three quarters, as the plants become more resistant to many pests.


A shrub is a small to medium-sized plant that has multiple stems and shorter height than a tree, usually shrubs are under 6 m (20 ft) tall, Small, low shrubs are generally less than 2 m (6.6 ft) tall.

Shrubs are generally considered to be broad-leaved plants, When clipped back many suitable species of shrubs develop dense foliage with the small leafy branches growing close together.
Many shrubs respond well to renewal pruning whilst Other shrubs respond better to a selective pruning to reveal their structure and character.

Ornamental grass varieties range over many colours and types and the height range of grasses is wide, from tall growing to very attractive dwarf species seldom exceeding 6in. in height. A few grasses, like the pampas grass (Cortaderia selloana), is grown as much for its feathery plumes in late summer, as for its foliage effect. In the main ornamental grasses are foliage plants, often variegated, sometimes bluish-green in colour.
Grasses are mostly easy plants to grow, not at all fussy about soils.
There are a few grass varieties that can easily get out of hand and need to be trimmed, or if planted in the right place, they would not be a problem and they could be left to there own devises.
There are grass varieties most suited to boggy soils. These go well around the ponds or water features.
The variegated types of grass offer something different and attractive, set amongst other plants in your boarders.
The bluish-green grass varieties also offer a distinctive foliage colour not found in most other general garden plants.


conifers are usually a woody plant or tree many varieties have a distinctly scented resin, this is secreted to protect the plant from insects and fungus's.
Many varieties of conifers are evergreens and usually have long, thin and have a needle-like leaves but some have a flat, triangular scale-like leaves.
Conifers have been used for ornamental purposes with a wide range of different forms, sizes, and colours available.
The size of mature conifers can vary from less than one meter, to over 100 meters.


clematis are among the most popular of all garden plants and some varieties provide a second period of interest with a flush of flowers, or decorative seed heads.
The woody stems of a young climbing clematis is fragile and will twist and curl around supporting structures to anchor the plant as it climbs.
The cool temperate species are deciduous with the warmer climate species being evergreens.
Some species of clematis are shrubby, while others are herbaceous perennial plants.

Our advice to prospective customers is don't buy more plants than you can comfortably sell, it is better to buy a few at a time and keep them fresh looking.

If you do over buy, most of the varieties we sell can be potted on and sold later as specimen plants when in flower at a premium price.


We believe it is better to pot the plug grown plants into either 7cm. - 8cm. or 9cm pots and grow them on to the point of sale - which during the growing season need only be a few weeks - then if you have any unsold plants, pot on again into either 1Lt. - 2Lt. or 3Lt. to produce quality plants for sale later.

The  large plugs we offer can be potted straight into larger containers where they will quickly make up and produce nice quality specimen plants.

Never allow the plants to be displayed for sale if they are looking tired and bedraggled, trim them and pot them on turning them into money.

Potting Compost

It is essential to use a good quality compost, it does not matter if you mix your own or buy in a propriety brand, just so long as it is an 'Open' compost with a good AFP, (air filled porosity) which will allow the roots to breath.

It is essential, in our opinion, to use a slow release fertiliser and a insecticide mixed in to control the Vine Weevil and other soil born pests, some of these chemicals will also control Aphid etc.

When you purchase your plants we can advise on suitable composts and pot sizes free of charge.

Our Plug Plants, if potted into 9cm pots, can be ready for sale or planting in approximately 8 weeks during the "peak" growing season*

Once you have potted your plants give them a really good watering in, and I mean a good watering, not just a 'Dribble' that only wets the surface, you must make sure all the compost in the pot is wet.

Leave any further watering until the composts is just moist and then water normally as and when the plant needs it, never keep the compost saturated all the time, allow it to go to just moist so that the air can enter and allow the roots to breath, this should happen naturally as the plants take up more water.

Watch the watering during the winter, don't get them too wet, on the other hand don't let them dry out either.

One important time to watch out for dryness is in the winter after a spell of very hard frost, when the compost thaws out the water will evaporate, leaving your plants dry.

Watch out all the time for Aphid and Caterpillar's etc. as these can devastate a crop in a very short time. It is best to have a regular spay program in force if you want to keep on top.

If you don't believe in using chemicals there are various other more friendly methods of control, but which ever you decide to use it is imperative that you keep the plants free from pests and decease's or you will not be able to sell them.
