Pittosporum trees can grow to different heights, depending on the species and the conditions they are grown in. They can reach heights of up to 25 feet in the wild and be shaped like a large shrub or into a small tree.
If kept in a more sheltered space, they can reach heights of barely 5 feet. Pittosporums tend to rapidly grow to approximately 10 to 12 feet when they are planted in open, sunny locations. Some species of Pittosporum can even reach heights of up to 40 feet if they are provided with adequate space and fertilizer.
Where is the place to plant pittosporum?
The best place to plant pittosporum is in a sunny to partly shaded spot in fertile, well-drained soil. Pittosporum does best in moist, well-drained soil, but it can also tolerate dry conditions. It is best planted in a sheltered position away from strong winds, although some varieties can tolerate coastal conditions.
It grows best in fertile soil that contains plenty of organic matter. When planting, dig a hole that is the same depth as the pot and twice as wide. Backfill the hole with the soil mix, and mix in some compost before planting if the soil is not particularly nutrient rich.
Water the plant well after planting, and then water regularly as needed.
Is pittosporum a tree or shrub?
Pittosporum is actually a type of flowering plant in the Pittosporaceae family, and is sometimes referred to as a “shrub”. However, some varieties can grow to a height of as much as 20 feet, so it is often referred to as a “small tree”.
It is an evergreen species with fragrant, waxy flowers that blossom in the spring, and can be identified by its unique bark and its round, glossy green foliage. It is highly adaptable and can thrive in a variety of soil and climate conditions, which is why it is often used as an ornamental plant in gardens or as a hedge or screen.
Pittosporum is an excellent choice for gardens that need a low-maintenance, easy-care plant that adds color and beauty to the landscape.
Do pittosporum have deep roots?
Yes, pittosporum have deep roots. Pittosporums are evergreen shrubs or trees that have roots that grow deep into the soil. The roots of pittosporum can reach depths of up to 16 feet and are typically twice as deep as the height of the plant.
These plants have a fibrous root system that helps them gain access to deeper nutrients and water in the soil. The taproot of pittosporum acts as an anchor for the plant to help support its growth. Additionally, due to their deep roots, pittosporums can survive in drought conditions by accessing moisture and nutrients that other plants may not be able to reach.
How do you encourage pittosporum growth?
There are a few things that can be done to encourage pittosporum growth.
Firstly, it is important to plant pittosporum in a spot that is well-draining and receives plenty of sunlight. Pittosporums should be planted in soil that is high in organic matter and that has a pH range of 6-7.
5, and if the soil is acidic amendments such as lime or sulfur should be added.
Regular fertilization in the plant’s first growing season is beneficial for encouraging pittosporum growth. Thereafter, once or twice-yearly fertilisation with a slow-release fertilizer formulated for acid-loving, evergreen shrubs should maintain healthy plant growth.
Pittosporum is a shallow-rooted species and prone to drying out, so plants should be regularly watered during dry periods to maintain adequate moisture levels.
Finally, pruning should be used to help keep pittosporum plants looking their best, as well as helping to control size. The best times to prune pittosporum are in the late winter and early spring, when the plant is in its dormant stage.
Pruning to shape and remove dead and diseased branches is important in helping encourage pittosporum growth.
How fast does lemonwood grow?
Lemonwood grows at a moderate to slow rate. The rate of growth depends on multiple factors, such as soil nutrient availability and climate, but typically lemonwood will grow between two to three feet per year.
Lemonwood make wonderful ornamental trees, so it is important that they are planted in the right conditions to ensure they reach their full growth potential. They thrive in well-drained, sandy soil and prefer full sun.

In addition, lemonwood trees are relatively drought-tolerant and can survive for extended periods without any irrigation during the dry months.
It is important to note that lemonwood trees will not reach their full size for at least five years after planting, so patience is needed to experience the full beauty and benefits of a lemonwood tree.
How far apart should you plant pittosporum for a hedge?
The spacing for Pittosporum for a hedge will depend largely on the variety you are planting and the desired effect. Generally, for a hedge where you trim the top, thin out the middle and let the bottom grow freely, you should leave approximately 3 to 4 feet between plants.
However, if you are looking for an informal hedge that is tightly knit, with short dense growth, then you should plant the Pittosporum at around 2 to 2.5 feet apart. For a formal hedge, the plants should be spaced around 4 to 6 feet apart.
When planting Pittosporum for a hedge, make sure that you plant in groups of at least three plants, so that the hedge can eventually form a strong and dense wall. Finally, be sure to water the plants regularly for optimum growth.
Why is my pittosporum wilting?
There are a variety of potential causes as to why your pittosporum may be wilting. First, it could be due to a lack of water. Pittosporums need to consistently be watered when soil is dry to remain healthy.
Be sure to water your plant regularly, especially during the warmer months. Additionally, wilting could be indicative of a nutrient deficiency in the soil. Your pittosporum may need to be fertilized to ensure it is receiving the proper nutrients from the soil.
A third potential cause of wilting is a pest infestation. It’s important to regularly inspect your pittosporum for any pests or bugs that could be feeding off of its leaves. Lastly, too much direct sunlight or high temperatures can cause wilting, as well.
Make sure your plant is not constantly in direct sunlight, and if it’s in direct sun, monitor the temperature in its general vicinity to make sure it’s not too hot for the plant. If it is quite hot, it might be best to acclimate the plant to the sun slowly, starting out with indirect light.
Can pittosporum be cut back hard?
Yes, pittosporum can be cut back hard. This is a good practice to promote a healthy growth habit in pittosporums and to ensure your plants stay looking their best. When cutting back pittosporum plants, you should use sharp shears and avoid tearing the plant.
Be sure to make your cuts just above the first leaf or bud. This will encourage the plant to produce new growth from the point of pruning. For large, overgrown shrubs, it may be necessary to cut the plant back quite severely, removing all the top growth.
This will encourage the plant to create a dense habit and keep a neat shape. It is also important to take into account the rate of growth the plant typically has when pruning, as pittosporums are a relatively fast-growing plant.
If you cut back new growth too soon, it can inhibit the plant’s ability to fill out and achieve a desirable shape. That being said, pruning and cutting back pittosporum plants every few years will ensure that your plants stay healthy and look their best.
Can you over water pittosporum?
Yes, you can over water pittosporum. If a pittosporum is over watered, the roots can become waterlogged, which can lead to root rot. This will reduce the amount of water and nutrients that the plant can absorb, leading to unhappy and potentially dead plants.
To prevent over watering, check the soil for moisture and only water when the soil is dry. Make sure that the plant is in an area with well draining soil, and don’t water too frequently. It is also helpful to remember that different types of pittosporums have different water requirements.
Make sure to do your research before planting in order to make sure that you are providing your plants with adequate amounts of water.
Why do pittosporum leaves go yellow?
Pittosporum leaves can go yellow for a few reasons, depending on the species of plant. In Pittosporum tenuifolium, yellowing could be caused by a variety of factors, such as too much or too little water, improper fertilization, or incorrect pH levels.
It could also be caused by a fungal infection or a nutrient deficiency such as nitrogen, magnesium, and/or iron in the soil. If a Pittosporum is grown in direct sunlight, the leaves will turn yellow due to sunburn.
Another possibility is pest infestation such as aphids or mealybugs, and their excrement will cause a yellow discoloration of the leaves. To prevent yellowing leaves, ensure that the plant is getting enough water (but not too much), and that it is receiving the correct amount of sunlight and fertilizer for its particular species.
Check for signs of pests and consult a gardening specialist if necessary.
What causes brown leaves on pittosporum?
Brown leaves on pittosporum can be caused by several factors, including pests, fungal or bacterial diseases, cultural problems, or environmental factors. If pests are the cause, the leaves of the pittosporum may be stippled or spotted, and the pests can be aphids, mealybugs, whiteflies, or scale insects.
Additionally, fungal or bacterial diseases like stem blight, root rot, and ring spot can cause the leaves to brown. Cultural problems and environmental factors are also common causes of browning leaves.
Environmental stress, such as lack of consistent moisture or too much direct sunlight, can cause damage to the leaves and cause browning, while cultural problems such as improper pruning and excessive fertilizer can also lead to brown leaves.
Regardless of the cause, brown leaves on pittosporum may require pruning and treatment with fungicides or specialized solutions to bring the plant back to health.
