Baileys Cypress Pine (Callitris baileyi)

Callitris baileyi, or the Baileys Cypress Pine, is a coniferous tree native to Eastern Australia. It is found in Southeast Queensland in ten known locations, ranging from the state border to Goomeri in northern Australia and as far west as the Bunya Mountains range.

It also occurs in New South Wales in subpopulations on private land and the Koreelah National Park, west of Woodenbong. These subpopulations have been severely fragmented due to widespread habitat fragmentation from logging and farming. It is a slow-growing species typically found in dry, sandy soils and well adapted to drought conditions. Callitris baileyi was found in Acacia Creek and Sandilands near Tabulam in New South Wales; however, now it ceases to occupy that area.

Callitris baileyi is a terrestrial plant system that grows on rocky slopes, hilly or mountainous areas, in shallow and often clay soils at an extent of occurrence between 15,000 and 25,000 km². It is found in eucalypt woodland, commonly associated with Ironbark, Blue Gum and Spotted Gum trees. Compared to the New South Wales sub-population that emerges in open grassy eucalypt forests near creeks.

Here is some useful plant-growing information about Callitris baileyi:

Tree Height and Spread: Callitris baileyi is a relatively small tree, typically growing up to 10 meters in height and spreading to around 3 meters in width. The tree is conical, with a narrow crown and drooping branches covered in small, scale-like leaves.

Preferred Soil Type and pH: Callitris baileyi prefers well-draining, sandy soils with a pH range of 6.0 to 7.5. The tree tolerates poor soil conditions and can grow in soils with low nutrient levels. It is also able to take periods of drought and high temperatures.

Propagation: Callitris baileyi can be propagated from seed or by taking cuttings. The best time to collect seeds is in autumn or early winter when the cones have matured, and the seeds have been released. Seeds can be sown in pots or directly in the ground. Cuttings can be taken from young softwood growth in spring or summer and should be placed in a rooting hormone before planting.

Watering: Callitris baileyi is a drought-tolerant species, but young trees should be watered regularly until they become established. Once established, the tree can be watered infrequently during periods of extended drought. Overwatering can lead to root rot and should be avoided.

Pruning: Callitris baileyi requires little pruning, but any dead or diseased branches should be removed. Pruning should be done during the dormant season to avoid damage to the tree.

Pest and Diseases: Callitris baileyi is relatively resistant to pests and diseases but can be susceptible to borers and scale insects. Regular inspection of the tree can help to identify any pest infestations early. Insecticidal soap or horticultural oil can be used to control infestations. The tree can also be susceptible to root rot if it is overwatered.

Uses: Callitris baileyi has the potential to be a native conifer species in landscaping and as a feature tree in small to extensive gardens. Its conical shape and narrow crown make it ideal for smaller spaces and as a native alternative conifer species. The tree’s wood is highly valued for its durability and resistance to decay, and it is often used for fence posts, poles, and other outdoor construction projects. The tree is also used in traditional Indigenous medicine for its antiseptic properties.

Callitris baileyi is a slow-growing, drought-tolerant conifer adapted to dry, sandy soils. It requires little maintenance and is relatively resistant to pests and diseases. The tree is widespread in landscaping, and its wood is highly valued for its durability and resistance to decay. It is an excellent addition to any garden or outdoor space.
