PostSubject: Growing Acer And Achillea Effectively.   Sun Oct 16, 2011 3:23 pm

Acer are hardy deciduous trees, and this family comprises many well-known ornamental trees such as the common syca¬ more and the various maples, including the japanese kinds with finely segregated and brilliantly coloured vegetation.
In terms of augmenting these lovely trees the larger maples and syca¬ more will thrive in any ordinary garden soil and will not require special therapy. Regular pruning is not necessary, but some thinning and / or regulation of growth may be required in the case of young trees to pre¬ serve their symmetry. This is best done in February. The highly coloured and even cut-leaved Japanese maples are rather tender and should therefore be given a new sunny but sheltered destination. Moreover, they do best in a deep, well-worked soil, for preference of a light loamy character, because they do not thrive in wet ice cold clays. These also need certain regulation and thinning of the young growth the more so as they are usually planted as small specimens in prominent positions. Pruning should be as light as possible and it is best done in Feb. All kinds of Acer may be planted at any time from the end from October till early Drive, but care should be taken to establish the Japanese kinds once the soil is in carefully good working con¬ dition.
All species can be increased by means of seeds, which should be sown in a sheltered border outdoors or inside a cold frame as soon as possible after they are ripe. The "wings" should be broken from the seeds before sowing. Sometimes germination is slow, in which case the seeds should be exposed to frost in their minute season to hasten decay of their hard coats. The varie¬ ties, however, will not breed true in this way and must be disseminated by budding or grafting on to seedlings of the type where they have originated.
The Achillea are hardy herbaceous perennials and rock plants, and they may be roughly divided into a few sections. First the larger species most suitable for planting in the particular herbaceous border or in a reserved bed for slicing, and secondly the dwarf kinds most at. home in the rock garden or on the dry wall.
Typical examples of the first type happen to be Achillea eupatorium, Achillea millefolium Cerise Queen, and Achillea ptaimica. Good rock achilleas are Achillea. ageratifolia, Achillea tomentosa, and Achillea. clavenns.
The herbaceous achilleas will grow in any ordinary garden soil that has been well dug and do not require special cultural consideration. Indeed, they are amongst the easiest and hardest from herbaceous per¬ ennials. The long white plants roots of Achillea ptarmica should be spread out flatly when ever planting and covered using about 2 in. of soil. It is advisable to take the plants up each second or third year and divide these phones prevent overcrowding. The rock garden species should every be planted in well-drained not to mention rather sandy soil, as they are inclined to rot off during the winter in rich or heavy ground.
The simplest method of increase is by office at planting time, but there can be little doubt that the very best results are obtained simply by rooting cuttings of small growth in March, April, or May in very sandy soil in a cold frame. Plants grown in this way are more vigorous not to mention healthy than those brought up from divisions. Seeds of the species may also be sown during March in light soil inside a cold frame.
