Anvil Shape: Anvil pruners have one cutting blade and a flat metal surface. Scissor pruners also have one sharpened blade, but normally only the internal surface is ground flat. This blade cuts by rotating past the anvil blade as in a conventional pair of scissors. It is advisable to use scissor-type pruners for propagation because they make a cleaner cut and cause less crushing and bruising in the region of the cut.
Woody plants are the prime candidates for pruning and these come in the form of ornamental shrubs (including conifers), climbers, hedges and topiary and trees, as well as fruit trees, bushes and canes. Roses are deciduous flowering shrubs which need regular pruning to keep them healthy and capable of creating a radiant display each year.
Pruning tools should be functional as well as comfortable to use. They must be kept sharp if they are to function easily and successfully. Wash and wipe them after use and, if they are not to be used for a few weeks, coat metal parts lightly with oil.
Pruners are available in two basic forms—scissor and anvil. The scissor-like type cuts when one blade passes the other while the anvil type has a sharp blade that cuts when in contact with a firm, flat, metal surface known as an anvil.
Use these for cutting shoots high on fruit trees or climbing plants. They cut shoots up to
I in thick and from branches I Oft high.
A thunderstorm can develop individually within a warm, moist air mass, or above a high mountain; or groups of them can form as part of a low pressure system or a squall line. They occur most frequently, and with the greatest intensity, in subtropical latitudes during summer. They may strike at any hour, but are most common in the late afternoon or early morning over land and coastal waters.
The prime danger signal alerting you to a thunderstorm is a cumulus cloud growing larger, with its top being blown off into an anvil shape. Lightning in the distance is a positive sign of such a storm even if no thunder has been heard yet. |
