Propagation of Santolina pinnata neopolitana
Santolina pinnata neopolitana is a popular garden plant known for its ornamental and medicinal value. Propagation of this plant is relatively easy and can be done by various methods. Some of the propagation methods for Santolina pinnata neopolitana include:
Seed Propagation
Santolina pinnata neopolitana can be propagated through seeds, and this is the easiest and most common method. To propagate the plant using seeds, you should collect the seeds during late summer or early fall, when they are ripe. After collecting the seeds, clean them and remove any debris or chaff. You can then store the seeds in a cool and dry place until you are ready to plant them.
Before planting, you should prepare a well-draining soil mixture and moisten it thoroughly. You can then scatter the seeds on top of the soil and cover them with a thin layer of the soil mixture. Place the container in a warm and bright location, and ensure that the soil remains moist. Germination should occur within two to four weeks, and you can transplant the seedlings to their permanent location after they have grown to at least two inches tall.
Division Propagation
Santolina pinnata neopolitana can also be propagated through division, which involves separating the plant into smaller sections and replanting them. To propagate the plant using division, you should wait until the plant has become established and has begun to produce new growth. You can then dig up the plant and gently separate the clumps into smaller sections, ensuring that each section has a healthy root system and a few shoots.
You can then replant the sections in a well-draining soil mixture, ensuring that you space them adequately. Water the newly divided plants thoroughly, and place them in a bright and sunny location. You should also ensure that the soil remains moist until the plants become established.
Cutting Propagation
Santolina pinnata neopolitana can be propagated through cuttings, and this method is ideal when you want to produce an exact replica of the parent plant. To propagate the plant using cuttings, you should take stem cuttings during summer, when the plant is actively growing. You should choose healthy stems that are at least four inches long and have a few leaves on them.
You can then remove the lower leaves from the stem and dip the cut end in a rooting hormone. You can then plant the stem in a well-draining soil mixture and place it in a warm and bright location. You should also ensure that the soil remains moist until the cutting has developed roots. After the cutting has rooted, you can transplant it to its permanent location.

Here are some tips on how to manage these issues:
Common diseases
One of the most common diseases that can affect Santolina pinnata neopolitana is root rot, caused by overwatering or poor drainage.

To manage powdery mildew, prune off infected leaves and apply a fungicide spray according to package instructions.
Common pests
One of the most common pests that can affect Santolina pinnata neopolitana is spider mites. These tiny pests feed on the plant's sap, causing the leaves to turn yellow, dry up, and fall off. To manage spider mites, rinse the plant with a strong jet of water to dislodge the pests, and apply an insecticidal soap or oil if necessary.
Santolina pinnata neopolitana can also be affected by aphids, which suck the sap out of the plant and leave behind a sticky residue that attracts other pests. To control aphids, spray the plant with a mix of water and dish soap, or apply an insecticidal soap or oil according to package instructions.
By following these tips, gardeners can keep Santolina pinnata neopolitana healthy and free from common diseases and pests.
