If you are landscaper in Dublin or anywhere in Ireland you may want to increase your stock of flowers. There are several methods of raising new plants . Sowing seeds is a relatively inexpensive way for landscapers in Dublin or Ireland to produce a large amount of flowers for their garden. It is the standard way for annuals but beset with drawbacks for most perennials. Border and rockery perennials require a vegetative means of propagation if you want to reproduce a named variety. Seed rarely produce plants which are completely true to type. For some landscapers dividing up a mature clump is, of course the easiest method of vegetative propagation, but not all perennials can be split up in this way and even when practical you have to disturb an established plant. Cuttings are a much more practical proposition for landscaping designers in most cases if you want lots of new plants. The cuttings are usually taken from non-flowering shoot tips but roots, leaves and small basal shoots are also used.
For some landscapers that find gardening a hobby looking through the seed catalogues is one of the joys of gardening. Many gardeners begin their experience with a packet of Virginia Stock or Nasturtiums, and perhaps landscapers move too quickly to buying in bedding plants and container growing specimens , forgetting the thrill of starting from scratch. Growing plants from seed is perfectly simple if you follow a few rules. The first decision to make is whether you are going to raise the seedlings indoors (the half hardy annual technique) for planting out later or sow the seeds outdoors (the hardy annual or the biennial technique.)
