Hydrated lime can be used to raise the pH of acidic soils. This is also referred to as soil "sweetening." Hydrated lime is available from garden centers and should be applied in the amounts and using the procedures recommended on the packaging. See similar questions...

You should lime once every three years at a rate of one quart jar per one hundred square feet applied in the fall, or apply two ounces of liquid lime per one hundred square feet in the spring. See similar questions...

Lime is calcium oxide applied in granular form. Lime helps improve lawn color and density, controls thatch, and increases root development. Lime balances the pH levels in the soil that have been affected by the fertilizer applications throughout the year.

Spalled brick in an1860s lighthouse that was repointed with portland cement mortar about twenty years ago. The historic stone masonry units have deteriorated dramatically, while the portland cement mortar joints remain intact. It' s important to understand that historic buildings are very different than modern buildings in several key ways: First, historic brick--in particular--is softer than modern brick because modern brick is fired at a much higher temperature than was possible in the past.

Chicken manure is high in nitrogen, so it is considered "hot". It will need to be composted before putting it directly onto your garden. once it has broken down, it then becomes perfect food for the garden. A Polyphemus moth rests on the outside of the coop. Good thing! If it were on the inside, it would make a tasty snack for one of the hens. See similar questions...

Either. Pelletized is easier to apply but powder is cheaper. Use powder if you intend to incorporate. There is no difference in speed of reaction. See similar questions...

A lime render is a coating of lime-based material that was traditionally applied over rough, unsightly brickwork or rubblestone masonry walls. Non-hydraulic lime stuccos and hydraulic lime stuccos are common lime-based renders. In addition to these traditional applications, lime renders can restore some measure of protection to masonry buildings that have been sandblasted. (Sandblasting a masonry building is incredibly damaging. See similar questions...

Yes. As we have already mentioned on this page, historic brick was fired at a lower temperature and is typically softer than modern brick. Construction techniques have changed, but it's still important that the mortar accomodate the historic brick. Due to the prevalence of portland cement mortars (notably the standard Type N), very few masons have worked with traditional lime mortars. See similar questions...

There are a wide range of different lime mortars available, all with different characteristics, and suitable for different applications. Non-hydraulic limes (CL90) are commonly available as 'lime putty', in 25kg bags or by the tonne. Natural Hydraulic Limes (NHL) Mortars are commonly available in 25kg bags from a wide range of manufacturers. NHL's come in a range of classifications based on compressive strength in N/mm2 at 28 days: NHL 2, NHL 3.5 & NHL 5. See similar questions...

Before this century building techniques and materials were very different from those employed today. Traditional properties need to "breathe" to allow moisture inherent in a solid wall construction without a damp proof course to evaporate from the external stonework or render. Many old buildings are constructed from materials such as brick, cob and stone which are relatively porous and often of lower strength. Lime mortars were normally used for bedding and plastering.

Lime trees are a big wasp problem because they have large amounts of sticky sweet sap and because the whole tree acts as an attractant a single WaspBane wasp trap is likely to be swamped by such a large source of food. Rather than spend lots of money buying lots of WaspBane wasp traps which if used in sufficient numbers will help the problem it would be more sensible and definitely safer to replace the lime trees with an alternative variety of tree.

This is generally determined by the volume (tonnage) of lime used. A good way to think of quicklime is that it is hydrated lime without the water. It's important to understand that when water is added to quicklime it chemically combines with it to form two products: calcium oxide (quicklime) and carbon dioxide. The weight ratio is that 100 tons of pure calcium carbonate would ideally produce 56 tons of calcium oxide (quicklime). See similar questions...

Natural hydraulic limes set even when wet and come in a range of strengths. They are useful for building with stone or brick where the earlier set may speed up construction. You can also add a pozzolan such as metastar to a lime putty mortar. We suggest that for external bedding and pointing late in the year natural hydraulic lime should be used. It is capable of a faster initial set in cold weather. See similar questions...
