Trim as required; they may be used for hedging, but are best planted away from areas that have frequent pedestrian use, as they have fierce thorns. Some species can be invasive, so ensure that barberry is not a local weed. Propagation is from seed or softwood cuttings in early summer or from half-hardened cuttings later in summer. Very hardy and easily grown in normal garden soils, many birches are natural riverside plants that can tolerate quite damp conditions.
They will do best in well-drained fertile soil, with some moisture, and a position in full sun or part-shade. They can cope with extreme cold and exposure to wind. Trim lightly to shape but otherwise allow the natural form to develop. Birches are susceptible to fungi such as Armillaria mellea and Piptoporus betulinus. Propagate from softwood cuttings taken in summer, half-hardened cuttings in autumn, or from seed.
Buddleja species are popular garden subjects. They are easy to grow, undemanding in their requirements, and produce attractive foliage and abundant colourful flowers. The deciduous species are hardier than the evergreens, though none will tolerate prolonged severe winters. Plant in a sunny or partly shaded position with moist, fertile, well-drained soil.

Some plants show a preference for chalky and limy soils. Carry out routine trimming in spring to keep the plants tidy. Propagate from half-hardened cuttings in summer. Hardiness varies though none will tolerate prolonged frosty winters, and late frosts can devastate the new growth.
Most bottlebrushes prefer moist, well-drained, slightly acid soil in a sunny position and are only marginally frost tolerant. Regular trimming will keep the plants tidy, and encourage bushier growth and greater flower production in the next season.

Propagate from seed or half-hardened tip cuttings. Camellias can be quite frost hardy, but since many are winter- or early spring-blooming, prolonged winters can damage the flowers. Shaded or semi-shaded positions, acid to neutral soils, dry winters, and wet summers suit the majority. A freely draining site and purpose-designed potting mixes are essential for all species. When planting camellias, be mindful that they are long-lived; allow adequate room for their growth.
Propagation is by grafting, or from cuttings taken in late summer to winter.
Wait, What Is a Shrub?
Mature Catalpa trees are frost hardy but young plants and the spring growth are easily damaged. Also, hail and strong winds will tear the large leaves, so young trees are best planted in a sheltered sunny position.
The soil should be moist, humus-rich, and well drained. The species are propagated from seed sown in autumn; the cultivars from softwood cuttings taken in late spring or early summer. Hardiness varies, but all species tolerate moderate frosts and are easily grown in any sunny position with moist well-drained soil.

Most are quite wind-tolerant, and prefer dry-summer climates. Prune young plants; adult plants need little pruning apart from removing spent flowerheads. Bottlebrushes can be found growing from Australia's tropical north to the temperate south.

They often grow in damp or wet conditions such as along creek beds or in areas which are prone to floods. Bottlebrush Flowers, Fruits and Leaves The flower spikes of bottlebrushes form in spring and summer and are made up of a number of individual flowers. Bottlebrushes as Garden Plants Bottlebrushes make excellent garden plants. Pruning Generally speaking, light pruning with the genus Callistemon refers to pruning into the new seasons 'wood', that is, not cutting back into the interior of the plant where there is little or no foliage. This can take the form of:.
Having said all this, you may need to sacrifice flowers for shape in the establishment stages, and on occasions older tired Callistemon may regenerate from basal pruning all branches removed at ground level - the equivalent of a bushfire if you like. Additional fertiliser at the time, assists this process. All Rights Reserved. Propagation Bottlebrushes are easily grown from seed. The unopened fruits should be collected and stored in a warm place in a paper bag until the fine seeds are released.
The seed should be sown into a freely draining seed-raising mix during spring and summer. Bottlebrushes hybridise readily so, if you wish to be sure that you are preserving the features of the parent plant do not grow plants from seed, use cuttings instead. With all cultivars it is essential to propagate from cuttings to retain the form of the parent plant. Cuttings should be taken from semi-mature wood. Commonly Grown Bottlebrushes The following bottlebrushes grow well in most temperate parts of Australia and have been successfully cultivated at the Gardens.
Callistemon brachyandrus - Prickly Bottlebrush This prickly-leaved shrub grows best in well-drained soils in full sun and is an excellent plant for hot, dry areas. The tips of the small red flower-spikes are covered in yellow pollen and are most attractive. The rounded shrubs grow to about 3 m. Callistemon citrinus - Crimson Bottlebrush This hardy shrub is probably the best known bottlebrush and is widely cultivated. The bright red flower-spikes appear in summer and autumn. Crimson Bottlebrush grows well in wet conditions and usually reaches 4 m.
Plants should be lightly pruned and fertilised after flowering. Neglected or mis-shapen plants respond to hard pruning.

Callistemon formosus - Kingaroy Bottlebrush This attractive shrub is suitable for tropical and frost-free areas. Plants grow to 3 m tall and have weeping branches. Lemon-coloured flower spikes are produced throughout the year. It is planted as street tree in Kingaroy, Queensland. Callistemon pallidus - Lemon Bottlebrush A tough, frost tolerant species which grows well in most soil conditions. Understandably we play the role of cyclers through composting and mulching but ultimately these outside inputs should be waned over the years.
Instead our creative human interaction with nature through design and years of management allow us to procure these soil generating materials on site. In this article we will focus on the design and strategies and techniques within management of the first two and articles on animal systems will specifically address that facet. When developing integrated systems like food forests or windbreaks or even in the tropics with crop production, branches of trees and shrubs woody material with leaves are utilized for soil regeneration.
Some utilizable species maybe present already on a site in your outer zones especially those with invasive tendencies. I am not sure its exact role in the ecosystem yet, but as we have chopped the forest so much into fragmented bits we have created heaps of edge. Chemicals are used to control it often but I prefer hand powered saws and loppers to cut buck its rampant growth. I lay this material around other native forest tree crops there like spicebush and paw paw but also move it around the site to my cultivated tree crops.
These truthfully are not in relative location and demand the pickup truck but further planting out of biomass species in relative location has begun. One that I have chosen to plant next to tree crops is Siberian Pea Shrub, a nitrogen fixing, fast growing temperate legume. It forms one layer of support and there are options below and above that. Black locust and silk tree both are taller species that can be coppiced easily and the material used as mulch. The finer you cut it the faster it will break down as edge is increased.
While chipping wood is a fantastic way to create more edge and speed this breakdown up, in some ways a slower. I saw this at my work at Edible Tree Crop farm in Nelson New Zealend where we chipped mostly Tagasaste, a wonderful Mediterranean climate nitrogen fixing small tree, to feed the tree crops. Unfortunately the chips broke down very quickly and a scramble to mulch them further again ensued. Furthermore, when building a food forest, all layers that we normally think of should also contain support species.
Thus our human role is to overplant in the support species and over time role this excess vegetation back to our hungry food. From left to right- felling ax, machete, pruners, rice knife, brush clearing ax: tools for chop and drop. Walking through with a machete, secateurs, loppers, or pruning saws, allows us to balance shade and soil cover depending on the time of year.
Fungus is more active at this time and the sun and wind not such a limiting factor in terms of dehydrating the landscape. If planted in relative location to a cashew tree, the nitrogen-fixing plant like gliricidia will also slump off roots and feed the tree below the ground.
However if the rainy season has subsided you are better off having shade and wind protection so time your cutting so that your trees are fully mulched in rainy parts and when things start to dry out you are not scrambling to mulch then. Also when felling trees like black locust for posts, the tree tops are cycled through by chopping the branches fine with a machete and ax. I lay those around the paw paw patches along with other raked forest detritus as we clean up after the light logging.
This forms a long-term mulch source that feeds the fungus and slows waters descent through the system.

I focus on plants that coppice well knowing that plenitude of biomass will come again and again. Not only can woody material be cycled to enrich soils, but also the herbaceous layer which contains no woody stem can be cut back and fed to plantings. The classic example within organic gardening is using comfrey as its high biomass producing quality is easily exploited.
