Acacia baileyana is a small to medium sized tree that is endemic to eastern Australia. It has a few common names, including cooba, black wattle and silver wattle. The tree typically grows to a height of 15-25 meters and has a spreading crown. The leaves are dark green in color and are arranged in pairs along the stems. The flowers are yellow and occur in cylindrical clusters. The fruit is a woody pod that contains several seeds. Acacia baileyana is an important source of food and shelter for many animals in eastern Australia. The leaves are eaten by koalas and the flowers are an important source of nectar for birds and other animals. The tree is also used as a food source by humans, with the seeds being roasted and ground to make a flour. The wood is used for a variety of purposes, including making furniture and charcoal. Acacia baileyana is dying out in some areas due to habitat loss and clearing for agriculture. It is also threatened by the introduction of competing plants species. Conservation efforts are underway to protect the tree and its habitat.

About soil condition, Acacia baileyana grows best in well-drained soils with a neutral to alkaline pH, but it is tolerant of a wide range of soil conditions. It does not like wet or waterlogged soils.
Similar to other flowering plants, the Acacia baileyana needs sunlight to produce flowers. The amount of sunlight this plant needs depends on the climate. In cooler climates, the plant needs more sunlight than in warmer climates. If the plant does not get enough sunlight, the flowers will be small and the plant will not flower as much.
The temperature condition that is most ideal for the growth of acacia baileyana is warm weather. This plant is native to Australia, and in its natural habitat it experiences warm weather all year round. However, it can also grow in cooler climates, as long as the temperature does not drop below freezing.
Ideal humidity condition for this plant is 50% or higher. The plant will suffer if the humidity drops below 40%. The leaves will begin to turn brown and crisp, and the plant will stop growing. If the humidity gets too high, the plant may develop root rot.
About fertilizer, usually the plant does not need too much. If the leaves start to yellow, it could be a sign of over or under watering, or that the plant needs more fertilizer. For best growth, it's recommended to use a balanced fertilizer during the growing season and a higher phosphorus fertilizer during the flowering season. The roots of the acacia baileyana plant are strong and aggressive, so it's important to be careful when planting near other plants or structures. It's also important to keep the roots moist, but not too wet, as they can rot if they're constantly wet.
Pruning of the acacia baileyana is essential to the health of the plant and should be done on a regular basis. Pruning will encourage new growth and help to keep the plant from becoming overgrown. When pruning, be sure to remove any dead or damaged branches.
Propagation is generally easy from seed or cuttings. Sow seed in early spring in a well-drained seed-starting mix. Place the seed-starting mix in a warm location until germination, which usually occurs within two weeks. When seedlings are large enough to handle, transplant them into individual pots filled with a standard potting mix. Keep the soil moist but not soggy and provide bright light. After the danger of frost has passed, acclimate the seedlings to outdoor conditions over a period of seven to 10 days before transplanting them into the garden. To take cuttings, select stems that are 6 to 8 inches long and cut them just below a leaf node with a sharp knife. Remove the lower leaves and dip the cut end of the stem in rooting hormone. Insert the stem cutting into a moistened potting mix, making sure that at least two leaf nodes are buried. Provide bright light and keep the soil moist but not soggy. After the cuttings have rooted, which usually takes four to six weeks, transplant them into individual pots filled with a standard potting mix. After the danger of frost has passed, acclimate the seedlings to outdoor conditions over a period of seven to 10 days before transplanting them into the garden.
Usually, the plant growth rate is determined by the growing conditions. In general, they prefer full sun and well-drained soil, but can tolerate partial shade. They are tolerant of a wide range of soil types, including heavy clay. Once established, they are very drought tolerant. They can be sensitive to frost, especially when young. They have a moderate to fast growth rate, depending on the above conditions.
Common problems for this kind of plant are scale, mealybugs, and spider mites. These pests are typically found on the underside of the leaves and can cause the leaves to turn yellow and drop off. If you see any of these pests on your plant, you can try to remove them by hand or with a soft cloth dipped in soapy water. You can also treat the plant with an insecticidal soap or neem oil.
