If the air is too moist, the leaves will turn yellow and the plant will be more susceptible to fungal diseases.
Regarding fertilizer, usually the plant does not need much. If you live in an area with poor soil, you might need to give it a little extra help in the form of a root booster.

Pruning is an important part of caring for your pyracantha mohave. It helps to encourage new growth and keep the plant healthy. You should prune your pyracantha mohave in late winter or early spring, before new growth begins. Use sharp, clean pruning shears to make clean cuts. Remove any dead or damaged branches, as well as any branches that are rubbing together. You can also prune to shape the plant or to control its size.
Propagation is accomplished by rooting hardwood cuttings taken from the plant in late winter or early spring. Cuttings should be 4 to 6 inches long and be taken from new growth that is just beginning to harden off. Before planting the cuttings, dip the lower 2 inches in rooting hormone. Fill a planting container with a well-draining potting mix and make several holes in the mix with a pencil. Stick the cuttings into the holes, making sure that at least 2 inches of the cutting is buried in the potting mix. Firm the mix around the cuttings and water thoroughly. Place the container in a plastic bag to create a humid environment for the cuttings. Set the bagged container in a bright location but out of direct sunlight. Keep the potting mix moist but not soggy and wait for the cuttings to root, which usually takes four to six weeks.
Usually, the plant growth rate during the spring and summer months, when the weather is warm and the days are long. However, some growth may occur during the fall and winter months if the plant is in a sheltered location. The ideal growing conditions for pyracantha mohave include full sun and well-drained soil. This plant is tolerant of average soil conditions, but it will not tolerate wet or soggy soil.
Common problems for this kind of plant are powdery mildew, canker, and scale. Powdery mildew is a white powdery fungus that appears on the leaves and stems of the plant. Canker is a black or brown sunken area on the plant that is caused by a fungus or bacterium. Scale is a small, hard, armored insect that sucks the sap out of the plant.
