This section about soil (which is several pages long) is extremely important on understanding what effect plants and clay will have on your house, outbuildings, paths, patios and garden wall foundations. |

The house below was built on sand at the bottom of a sloping lawn. The 12 feet wide patio stretching the length of the back of the house was laid on top of 2 feet thick of blue clay. The lawn sloped down towards the house and also sloped towards the hedge you can see on the right hand side. When it rained, the water would flow off the lawn onto the patio and then to the house. The water then percolated down to the clay, which then swelled (clay can usually absorb 40% of its own volume in water before it turns from a solid to a liquid) which caused a break in the wall above the bay window, resulting in subsidence to the building 6 years after it was built . |

So I had the soil analysed to see how fertile it was. In taking the soil samples, I discovered that the areas that I took the soil samples from were sandy rather than clay. |
||
When I took up some slabs by the house, I discovered that there was clay underneath them.I produced the following current design followed by the proposed structural design:- |
||
The above structural design would then produce the requested requirements. I dug a spade wide trench and 3 feet deep along the outside wall of the dining room and kitchen to discover that the clay was 2 feet thick. I lined the trench with Plantex membrane (available from Travis Perkins) and filled it with Type I MOT Roadstone from Allsand Supplies. The Plantex stops the Roadstone from mixing with the clay and sand surrounding it and the Roadstone will drain any water to the sand below without heave or subsidence. I suggested that the foundations for the conservatory wall should be of solid concrete at least 1 foot into the sand under the blue clay:- |
||
|
||
6 cubic yards of concrete were used to create these conservatory wall foundations.The soil within this concrete could then dry out and it would then not get wet from rain and therefore not swell or shrink. |
||
The Kompo Mulch and Organic Manure were stacked under the pine trees in the Woodland Border before being mixed with the transferred soil on the levelled lawn. The trunks of the pines swelled so much in 2 weeks that the bark split. This was due to the fact that the nutrients in that mulch were started to be used by the pine trees which had been starved of any nutrients for years. |
||
The new Path/Patio at the back of the house was then sloped away from the house and the rain drained to the Gully, thence to the Sump in the middle of the garden. |
||
The levelled lawn then needed a Patio wall to stop the earth from being unsurported. |
||
Levelled lawn in both directions, with the conservatory/path areas sloping away from the house to allow rainwater to be collected and taken to the sump, instead of causing further damage to the house. |

Proposed re-use of old patio slabs to reduce costs, instead of buying new Marshalls ones as shown in a previous plan. THE DAMAGE CAUSED TO THIS HOUSE WAS DUE TO THE BUILDER USING CLAY INSTEAD OF SAND NEXT TO THE HOUSE, WHICH STUCK TO THE EXTERNAL HOUSE WALL AND PUSHED IT UP AND DOWN ACCORDING TO HOW WET OR DRY IT BECAME. ALSO, THE BUILDER HAD SLOPED THE PATIO TOWARDS THE HOUSE INSTEAD OF AWAY FROM IT.ANY HARDSTANDING NEXT TO A BUILDING SHOULD SLOPE AWAY FROM IT OR HAVE DRAINAGE BY THE HOUSE TO TAKE THE WATER AWAY. IF THE WATER IS REMOVED TO A SUMP, THEN MAKE SURE THAT THAT SUMP IS NOT IN CLAY SOIL. IF SO, WATER ENTERING IT WILL NOT DRAIN AWAY - (put the water into a French Drain alongside an evergreen hedge, so that the water can drain from the pipe into the surrounding peashingle; through the geotextile, which prevents the roots and soil entering that area, and finally into the soil alongside where the roots of the hedge can use it). |

3 - Drive Foundations What are the Soil Nutrients besides What types of organisms are found in the soil? and What Pysical changes occur in Soil because of weather? and what Chemical changes occur in Soil because of weather? leading to This leads to an 3b Pre-Building Work for Builders to treat polluted soil using phyto-remediation plants. Then, they could follow my following Suggested Action Plan for Builders after they have built their houses:-
And finally on the same day pour a depth of 11 inches (27.5 cms) depth of the builders soil mixture detailed below onto the remainder of the new garden areas and alongside the Instant Hedging.
A fortnight later the following type of turf containing RTF (Rhizomatous Tall Fescue), bred by Barenbrug Research USA, could be laid over the proposed lawn areas. The roots of that grass will reach the clay below and stabilise the new builders soil mix, before the proposed owners view the property a month later. The builders soil mix should within 3 months become roughly the same proportion of clay, silt and sand which is within a Sandy Clay Loam to create a sweet spot for growing plants as shown on How is material lost from the soil? Page, since it will mix with the clay below.

Design Cases When designing a garden, it is vital to know who and for how long the resulting designed and landscaped garden is going to be maintained by. The book 'The One Hour Garden' describes what maintenance work can be done in the time that you have allotted; and therefore what besides a lawn, you can have in your garden. My redesign and construction work to be done on my 3 gardens - as shown by Case 2 - must be to reduce the maintenance time required to the time I have available. If the gardens are first weeded, pruned, mulched, mown and bare earth converted to lawns using grass seed, then construction can take place in the future - as free time allows during a week or fortnight after the maintenance has been done. In Case 4, the combination of the Structural and Planting Designs would create a garden that I would be able to maintain in one day a fortnight. I would install a 3" deep mulch in the spring on the beds, so that I can prune the shrubs/trees and hoe the odd weed; whilst the father mows the lawns, the mother tends the vegetable garden and their teenage daughters play football!! The children in Case 5 loved to look at creepy-crawlies and wildlife, so that together with low-cost the design for different areas in a terrace house garden was created.
Construction Cases Case 3 is building a drive on clay and it is important to get the part you will not see - the foundations - done correctly. Case 8 is creating a pond with its pitfalls for foundations.
Maintenance Cases If you are asking someone to maintain your garden, then do provide the complete picture. If as in Case 1, you intend to sell the property, then look at this - as not a maintenance but as a selling job - and get that job done instead. Case 6 is creating a vegetable garden in a back garden during the maintenance program of one day a fortnight to maintain it and the remainder of the back and front gardens. This was done over 7 years using a crop rotation system Concrete ponds are likely to crack open due to movement in the ground levels due to being in clay or vibration caused by road traffic if it is fairly close. Case 7 shows no planting shelves for the pond plants. |

Problems for Houseowners and Builders when the new home is surrounded clay and how to solve them. 8 problems caused by clay:-
|
||
Builders do sell the original topsoil including
where the new building and its garden areas are to be built. The consolidated parent material (bedrock) is usually sand, chalk or clay with flint possibly. At the end of building; the builders rubble is covered with possibly only a 2 inch (5 cms) depth of imported topsoil, which might be the washings from the sugar beet in the sugar industry. This is covered with turf and the unsuspecting public is offered the result. As likely as not one of their gardens slopes towards the house and even with the modern depth of foundation wall, there is no guarantee that subsidence will not occur.
If every garden of a new house had a 12 inch depth of soil removed from its new garden area, then at the end of the building work, the Aquadyne Drainage System would be laid round the entire boundary. Next to it then plant the relevant Instant Hedge on the non-house wall sides to absorb the rainwater collected by that drainage systemThe mix to change clay soil into a friable useful soil in less than 4 months for the above domestic garden problem was in royal blue colour typing. Using the burgundy colour typing components, the builder could create the following soil mix for his gardens:
If water with 150 kgs of clay was first added to the Concrete TruckMixer and then the required volume of cullet followed by the required volume of waste plasterboard, the mixture is then mixed for an hour. If the cullet/waste plasterboard mixture is passed through the poultry houses to mix with the poultry litter on the litter floor before being collected into the next Concrete TruckMixer, then the houses would be cleaner and smell less. The required volume of waste from beer making could replace the Peat above and the requisite Sulphate of Iron and Sulphate of Potash could be added to the Concrete TruckMixer before that mixture from the Poultry Farm litter floor is added. That soil mixture could then be mixed for 30 minutes before applying it to the garden areas of the new houses built by the builder to an 11 inch (27.5 cms) depth. The resulting mixture would then integrate with the clay and create a deep topsoil within 3 months. All the requirements for a soil as shown in the figure above would then have mixed together and time will increase the bacteria and get a new soil structure created. The following type of turf could then be laid over the proposed lawn areas a fortnight later:- RTF (Rhizomatous Tall Fescue), bred by Barenbrug Research USA, produces rhizomes (an underground stem) that send a shoot up to the soil surface while extending new roots downwards. In fact, RTF can root to 1.5 metres deep giving it a chance to tap into water reserves that normal lawn turf cannot reach. |

Section below provides details about flowers |
|
|
The following details come from Cactus Art:- "A flower is the the complex sexual reproductive structure of Angiosperms, typically consisting of an axis bearing perianth parts, androecium (male) and gynoecium (female). Bisexual flower show four distinctive parts arranged in rings inside each other which are technically modified leaves: Sepal, petal, stamen & pistil. This flower is referred to as complete (with all four parts) and perfect (with "male" stamens and "female" pistil). The ovary ripens into a fruit and the ovules inside develop into seeds. Incomplete flowers are lacking one or more of the four main parts. Imperfect (unisexual) flowers contain a pistil or stamens, but not both. The colourful parts of a flower and its scent attract pollinators and guide them to the nectary, usually at the base of the flower tube.
Androecium (male Parts or stamens) Gynoecium (female Parts or carpels or pistil) It is made up of the stigma, style, and ovary. Each pistil is constructed of one to many rolled leaflike structures. Stigma This is the part of the pistil which receives the pollen grains and on which they germinate. Style This is the long stalk that the stigma sits on top of. Ovary The part of the plant that contains the ovules. Ovule The part of the ovary that becomes the seeds. Petal The colorful, often bright part of the flower (corolla). Sepal The parts that look like little green leaves that cover the outside of a flower bud (calix). (Undifferentiated "Perianth segment" that are not clearly differentiated into sepals and petals, take the names of tepals.)"
The following details come from Nectary Genomics:- "NECTAR. Many flowering plants attract potential pollinators by offering a reward of floral nectar. The primary solutes found in most nectars are varying ratios of sucrose, glucose and fructose, which can range from as little a 8% (w/w) in some species to as high as 80% in others. This abundance of simple sugars has resulted in the general perception that nectar consists of little more than sugar-water; however, numerous studies indicate that it is actually a complex mixture of components. Additional compounds found in a variety of nectars include other sugars, all 20 standard amino acids, phenolics, alkaloids, flavonoids, terpenes, vitamins, organic acids, oils, free fatty acids, metal ions and proteins. NECTARIES. An organ known as the floral nectary is responsible for producing the complex mixture of compounds found in nectar. Nectaries can occur in different areas of flowers, and often take on diverse forms in different species, even to the point of being used for taxonomic purposes. Nectaries undergo remarkable morphological and metabolic changes during the course of floral development. For example, it is known that pre-secretory nectaries in a number of species accumulate large amounts of starch, which is followed by a rapid degradation of amyloplast granules just prior to anthesis and nectar secretion. These sugars presumably serve as a source of nectar carbohydrate. WHY STUDY NECTAR? Nearly one-third of all worldwide crops are dependent on animals to achieve efficient pollination. In addition, U.S. pollinator-dependent crops have been estimated to have an annual value of up to $15 billion. Many crop species are largely self-incompatible (not self-fertile) and almost entirely on animal pollinators to achieve full fecundity; poor pollinator visitation has been reported to reduce yields of certain species by up to 50%." |

The following details about DOUBLE FLOWERS comes from Wikipedia:- "Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. The double-flowered trait is often noted alongside the scientific name with the abbreviation fl. pl. (flore pleno, a Latin ablative form meaning "with full flower"). The first abnormality to be documented in flowers, double flowers are popular varieties of many commercial flower types, including roses, camellias and carnations. In some double-flowered varieties all of the reproductive organs are converted to petals — as a result, they are sexually sterile and must be propagated through cuttings. Many double-flowered plants have little wildlife value as access to the nectaries is typically blocked by the mutation.
There is further photographic, diagramatic and text about Double Flowers from an education department - dept.ca.uky.edu - in the University of Kentucky in America.
