Every urban tree is unique. Anyone who milled with them would have to carefully consider every cut and work with each individual tree’s shape and growth pattern. But isn’t this appropriate consideration for a tree that contains our very breath and our history?
Plum trees normally require little pruning, although removing diseased wood is always necessary. European plums — including prunes, greengages and damsons — bear fruit on two or three-year-old wood. If all new shoots are cut back by about two-thirds and all internal growth cut out completely, the trees will continue to bear excellent crops of well-sized plums every year.
Most orchids like some form of lighting, some more than others. Cymbidiums seem to enjoy full sun up to December and then some shade is required. Rock Orchids such as Dendrobium speciosum/Sarcochilus are happy with full sun throughout the year, but need protection from the direct light on hot summer days. Masdevallia and Paphiopedilum (slipper) orchids prefer shaded areas. Most orchids need to be moved to a couple of locations during the year.
Hellebores mostly originate in inland regions of central and southern Europe. The main concentration of helleborus species in the wild is found in the mountainous Balkans. Hellebores are found as far west as Spain and Britain and as far east as Turkey and the Republic of Georgia. Helleborus argutifolius and H. lividus are found on the Mediterranean islands of Corsica and Majorca respectively. But by far the most geographically isolated species is the rare Chinese species Helleborus thibetanus.
Over the past few years dahlias have become increasingly popular, and rightfully so for few other plants offer the gardener such a variation in colour and form. In 2013 we had a visit from a member of the Hobart Horticultural Society Dahlia Group who spoke to us on cultivating and showing dahlias and donated a number of tubers which were made available to members.
