At our nursery we have a large range of native rainforest species for establishing rainforest plantings but as many of these species have various seeding times that are affected by weather conditions and with some only seeding every 2 to 4 years with many seeds having only a short shelf life, means that the range of species changes from time to time. So contact us to find out what is now available or download our species list here. Species List.pdf
Trees for timber plantations must come from nurseries which practice a precise and naturalistic seed propagation methodology suitable for native rainforest species. We need to assure ourselves and our clients that the tube stock seedlings of timber trees are of ideal condition and structure and are given the best chance for establishment and growth in the field; healthy defect-free tube stock seedlings with well developed and vigorous root systems, after all, are the very foundations of the plantation.
There are a number of inherent advantages to using tube stock seedlings for tree planting projects. They represent the early vigorous stage in plant growth and establish readily; they are better suited to withstand dry conditions after planting; and they are cost effective, space saving and easily transported.
To achieve uniformity in tube stock, the seedlings are potted from seed boxes; because of erratic germination, direct seeding into tubes is unreliable. When potting, plants should be held over the empty pot and the potting mix poured around the plant so the seedling will be well shaped and centralised with a straight root system. We use tubes with root trainer ribs. This design has the effect of sending the roots straight down the line of the pot. Smooth sided tubes have the effect of the roots circling around the pot; this circling root structure is extremely detrimental to seedling establishment and growth.
After potting, the tube containers are placed in successive regimes of shade, semi-shade and full sun to promote acclimatization and hardness. The tube stock containers are then placed in racks with air space under the pots to enable air-pruning of the root system. When the protruding roots come into contact with the atmosphere a callous is formed on the end of the root; new healthy roots are formed immediately after the tree is planted in the field.
When the trees are taken from the nursery they are usually packed in flat bottomed boxes but should not be held in these containers any longer than a week because the new roots will shoot from the bottom of the pot. Should they be kept longer than a week, these plants must be placed into air pruning racks. Trees when held in flat-bottomed boxes for longer than a week will have roots protruding out of the bottom of the pot. If the seedlings are planted without the roots being trimmed, the roots will fold under the bottom of the seedling in the planting hole causing a J root deformation.
