About soil condition, laurel shrubs prefer well-drained soils, whether sandy, loamy, or clay. They also prefer slightly acidic to neutral soils, with a pH of 6.0 to 7.5, although they can tolerate some alkalinity. In terms of nutrients, they prefer soil that is high in organic matter and that is somewhat moist but not waterlogged.
So, like the other plants, laurel shrubs need sun to grow. They need at least six hours of sunlight a day to thrive. If they don't get enough sun, they will become leggy and their leaves will begin to yellow. They may also produce fewer flowers.
The temperature condition that is most ideal for a laurel shrub is one that is cool and moist. These shrubs prefer locations that do not experience drastic changes in temperature, so they are often found in areas with moderate climates. When temperatures become too hot or too cold, laurel shrubs can become stressed and may even die.
Ideal humidity condition for this plant is around 50%. If conditions are too dry, the leaves may become crispy and fall off. If conditions are too wet, the plant may become susceptible to fungal diseases.
Discussing fertilizer, this plant prefers a low nitrogen and high phosphate fertilizer to encourage blooming. A fertilizer with an NPK ratio of 5-10-5 or 5-10-10 is ideal. Laurel shrubs should be fertilized in early spring before new growth begins. It's best to apply the fertilizer to moist soil and then water thoroughly to help distribute the nutrients down to the roots.
Pruning is an important part of keeping your laurel shrub healthy and looking its best. When and how you prune will depend on the type of laurel shrub you have. Some types of laurels need to be pruned more often than others.
Propagation is best done in early spring by taking stem cuttings from the tips of last year's growth. Cuttings should be taken from healthy, disease-free plants and should be about 4-6 inches (10-15 cm) long. Place the cuttings in a well-drained potting mix and keep them moist until they root, which usually takes 4-6 weeks. Once the plants are rooted, they can be transplanted into their permanent location.
Usually, the plant growth rate is slow to moderate. However, conditions such as soil quality and amount of sunlight can affect how quickly these plants grow. For example, if the soil is especially rich in nutrients, laurel shrubs may grow a bit faster. Or, if the plants are getting full sun exposure, they may also grow slightly faster than if they were in partial shade. Ultimately, though, laurel shrubs typically grow at a moderate pace.
Common problems for this kind of plant are dieback, leaf spot, and root rot. Dieback is usually caused by a fungal disease, while leaf spot is usually caused by bacteria. Root rot is caused by a variety of fungi, and is the most serious problem. It can kill the plant.
