Herb
The Royal Horticultural Society Encyclopedia of Herbs & their Uses by Deni Brown (ISBN 0 7513-020-31) covers over 1000 herbs grown worldwide for their culinary, aromatic, medicinal, and economic uses, as well as for the decorative qualities in the garden. It has:-

• an extensive catalogue of colour photographs,
• dictionary section gives detailed information on each herb,
• with garden designs and planting schemes.

If you see a little green guy in a Herb Profile, it means that you should not use this herb without professional advice.

The Herb Society of UK has designed and built a herb garden which is maintained by volunteers in the grounds of Sulgrave Manor that features herbs taken to North America from Europe and herbs which have come to us from North America. HerbExpert was formed to offer a unique reference point on growing and cooking herbs.

The Herb Society of America is dedicated to promoting the knowledge, use and delight of herbs through educational programs, research, and sharing the experience of its members with the community. The International Herb Association is a professional trade association providing educational, service and development opportunities for those involved in herbal endeavors since 1985.

Naturalize -
The practice of growing certain plants under as natural conditions as possible.
For example; daffodils are said to be naturalized when they are planted in grass and left to look after themselves.
The term is also used to describe plants from foreign countries which have established themselves so well in the country into which they have been introduced that they behave like native plants; and are able to maintain themselves without the aid of the gardener.

What to do about Subsidence caused by Clay? Page explains what to do about trees/shrubs/hedges that may damage the foundations of your property.
What happened to a new building, which was caused by the builder, 6 years after it was built. The new owner was then landed with a large bill. The Builder warranty is first 2 years, then years 3-10 can be covered by NHBC Buildmark.

Most modern houses cannot afford large shrubs, trees or hedges within 10 feet = 120 inches = 300cms of a house wall or a garden wall, so it is best to use:-
Growing Edibles in Containers inside your home,
and
Soft Fruit List with soft fruit bush (Blueberry, Gooseberry, Blackcurrant, Redcurrant, Whitecurrant or Jostaberry) instead of a shrub from the shrub lists provides you with the size of shrub suitable for most current gardens.
The Raspberry may be used as a mini-hedge in the garden to separate areas or against your boundary fences/walls.
The Blackberry, Boysenberry and Tayberry cane climbers can also be used as mini-hedges or to clothe walls/fences/pergolas.
They all provide you with edible fruit. The Soft Fruit Gallery compares colour photographs of some soft fruits,
and
Choosing a top fruit tree or remaining top fruit instead of a tree from the tree list provides you with a plant of a size that is suitable for most current gardens. These trees also produce edible fruit. Further details in these galleries -
Top Fruit Apple, Cherry, Pear
or
You could use 1 of the trees from the Deciduous and Evergreen Trees suitable for Small Gardens.

The overall amount of sunlight received depends on aspect, the direction your garden faces:-
North-facing gardens get the least light and can be damp.
South-facing gardens get the most light.
East-facing gardens get morning light.
West-facing gardens get afternoon and evening light.

-----

Acid Site - An acid soil has a pH value below 7.0. Clay soils are usually acid and retentive of moisture, requiring drainage. The addition of grit or coarse sand makes them more manageable. Peaty soil is acidic with fewer nutrients and also requires drainage.
Alkaline Soil - An alkaline soil has a pH value above 7.0. Soils that form a thin layer over chalk restrict plant selection to those tolerant of drought.
Bank / Slope problems include soil erosion, surface water, summer drought and poor access (create path using mattock to pull an earth section 180 degrees over down the slope). Then, stabilise the earth with 4 inches (10cms) depth of spent mushroom compost under the chicken wire; before planting climbers/plants through it.
Cold Exposed Inland Site is an area that is open to the elements and that includes cold, biting winds, the glare of full sun, frost and snow - These plants are able to withstand very low temperatures and those winds in the South of England.

Tree/Shrub Shape:-

Columnar Tree/Shrub Form

A tree shape designed by nature to be a haven for nesting birds.

Oval Tree/Shrub Form

Rounded or Spherical Tree/Shrub Form

Flattened Spherical Tree/Shrub Form

Narrow Conical/ Narrow Pyramidal Tree/Shrub Form.
These are neat and shapely, thus being trees for the tidy gardener. The narrowness of the tree means that bands of dense shade sweep across the garden - never creating dense shade in one area all day.

Broad Conical/ Broad Pyramidal Tree/Shrub Form.

These are neat and shapely, thus being trees for the tidy gardener.

Ovoid/ Egg-Shaped Tree/Shrub Shape

Broad Ovoid Tree/Shrub Shape

Broad-headed trees usually cast a large area of light dappled shade and have broad spreading branches so loved by birds and animals.

-----

Surface soil moisture is the water that is in the upper 10 cm (4 inches) of soil, whereas root zone soil moisture is the water that is available to plants, which is generally considered to be in the upper 200 cm (80 inches) of soil:-
Wet Soil has Saturated water content of 20-50% water/soil and is Fully saturated soil.
Moist Soil has Field capacity of 10-35% water/soil and is Soil moisture 2–3 days after a rain or irrigation.
Dry Soil has Permanent wilting point of 1-25% water/soil and is Minimum soil moisture at which a plant wilts.
Residual water content of 0.1-10% water/soil and is Remaining water at high tension.
Available Water Capacity for plants is the difference between water content at field capacity and permanent wilting point.

-----

Dust and Pollution Barrier - Plants with large horizontal leaves are particularly effective in filtering dust from the environment, with mature trees being capable of filtering up to 70% of dust particles caused by traffic. Plants can also help offset the pollution effects of traffic. 20 trees are needed to absorb the carbon dioxide produced by 1 car driven for 60 miles.
Front of Border / Path Edges - Soften edges for large masses of paving or lawn with groundcover plants. Random areas Within Paths can be planted with flat-growing plants. Other groundcover plants are planted in the Rest of Border.

Tree/Shrub Shape:-

Narrow Vase-Shaped/ Inverted Ovoid Tree/Shrub Shape

Fan-Shaped/ Vase-Shaped Tree/Shrub Shape

Broad Fan-Shaped/ Broad Vase-Shaped Tree/Shrub Shape

Broad-headed trees usually cast a large area of light dappled shade and have broad spreading branches so loved by birds and animals.

Narrow Weeping Tree/Shrub Shape

Very useful for children to use as a secret den. The narrowness of the tree means that bands of dense shade sweep across the garden - never creating dense shade in one area all day.

Sun Aspect:-
Full Sun: At least 6 full hours of direct sunlight. Many sun lovers enjoy more than 6 hours per day, but need regular water to endure the heat.
Part Shade: 3 - 6 hours of sun each day, preferably in the morning and early afternoon. The plant will need some relief from the intense late afternoon sun, either from shade provided by a nearby tree or planting it on the east side of a building.
Dappled Sun - DS in Part Shade Column: Dappled sunlight is similar to partial shade. It is the sun that makes its way through the branches of a deciduous tree. Woodland plants and underplantings prefer this type of sunlight over even the limited direct exposure they would get from partial shade.
Full Shade: Less than 3 hours of direct sunlight each day, with filtered sunlight during the rest of the day. Full shade does not mean no sun.

-----

Seaside Plants that deal with salt-carrying gales and blown sand; by you using copious amounts of compost and thick mulch to conserve soil moisture.
Sound Barrier - The sound waves passing through the plant interact with leaves and branches, some being deflected and some being turned into heat energy. A wide band of planting is necessary to achieve a large reduction in the decibel level.
Wind Barrier - By planting a natural windbreak you will create a permeable barrier that lets a degree of air movement pass through it and provide shelter by as far as 30 times their height downwind.
Woodland ground cover under the shade of tree canopies.
