Light Requirements
Diplacus aurantiacus ssp. australis is a sun-loving plant that requires full sun exposure to thrive. It grows best in areas with direct sunlight for at least 6 hours per day. Insufficient light can lead to leggy growth, poor flowering, and plant death.
Temperature Requirements
Diplacus aurantiacus ssp. australis is a heat-loving plant that grows well in warm temperatures. It is suitable for outdoor cultivation in USDA zones 7 to 10, where the minimum temperatures do not fall below 0°F. It can tolerate temperatures up to 100°F, but it requires ample moisture in hot weather. Cold temperatures can damage the plant, so it is important to protect it from frost and cold winds.
Soil Requirements
Diplacus aurantiacus ssp. australis grows best in well-drained soils that are fertile and slightly acidic to neutral (pH 5.5-7.5). The soil should be rich in organic matter and able to retain moisture without getting waterlogged. The plant can tolerate sandy soils, but it prefers loamy soil types. The addition of compost, manure, or other organic amendments can improve soil fertility and texture.

Fertilization for Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks
Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks benefits from light fertilization in the spring. Apply a balanced, slow-release fertilizer according to the instructions on the package. Avoid excessive use of nitrogen, as it can encourage foliage growth at the expense of flowers.
Pruning Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks
Prune Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks lightly after flowering to encourage bushier growth and more flowers. This plant responds well to light pruning and can be shaped to fit the desired space. Avoid pruning too heavily, as it can damage the plant.
Propagation methods for Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks
Diplacus aurantiacus, also known as sticky monkey-flower, can be propagated through multiple methods, including seeds, stem cuttings, and division.
Seeds
The plant produces small seeds that can be collected in late summer or early fall. The seeds need to be stratified by exposing them to cold temperatures for a period of four to six weeks to break their dormancy. After stratification, the seeds can be sowed in a well-draining seed-starting mix and kept moist until they germinate. It can take up to several weeks for the seeds to germinate.
Stem cuttings
Stem cuttings can be taken from Diplacus aurantiacus in the late spring or early summer. The cuttings should be about four inches long and taken from the tips of the plant's stems. The leaves on the lower half of the cutting should be removed, and the remaining leaves should be trimmed down to reduce water loss. The cutting can then be dipped in rooting hormone powder and planted in a well-draining potting mix. Keep the cutting moist and in a warm environment until it forms roots, which can take up to several weeks.
Division
The sticky monkey-flower can also be propagated through division. This method involves carefully digging up the plant and separating the root ball into smaller sections. The sections should have their own roots and shoots and can then be replanted in a well-draining soil mix. Water the newly divided plants thoroughly to help them establish and continue to keep the soil moist until signs of new growth appear.

Powdery mildew is a fungal disease that usually appears as white powdery spots on the leaves and stems of the plant. To manage powdery mildew, the affected parts should be removed and destroyed, and the plant should be sprayed with a fungicide.
Rust is another fungal disease that causes yellow, orange, or dark brown spots on the leaves and stems of the plant. If left untreated, rust can weaken the plant and even kill it. To manage rust, the affected parts should be pruned, and the plant should be sprayed with a fungicide.
Leaf spot is a fungal disease that causes brown or black spots on the leaves of the plant. The spots usually appear first on the lower leaves before spreading to the upper ones. To manage leaf spot, the affected parts should be removed, and the plant should be sprayed with a fungicide.
Pests
Diplacus aurantiacus (W. Curtis) Jepson ssp. australis (McMinn) R.M. Beeks can be affected by several pests, including aphids, spider mites, and whiteflies.
Aphids are small, soft-bodied insects that feed on the sap of the plant, causing stunted growth and leaf distortion. To manage aphids, the affected parts should be pruned, and the plant should be sprayed with insecticidal soap or neem oil.
Spider mites are tiny, spider-like insects that live on the underside of the leaves and suck the sap out of the plant. They can cause yellowing and bronzing of the leaves, and if left untreated, they can kill the plant. To manage spider mites, the plant should be sprayed with insecticidal soap or neem oil.
Whiteflies are small, winged insects that feed on the sap of the plant and cause yellowing and distortion of the leaves. To manage whiteflies, the plant should be sprayed with insecticidal soap or neem oil.
