Pittosporum shrubs are very hardy and tolerant of a variety of conditions. With proper care and maintenance they can live for many years. On average, they usually live between 10-15 years, with some species living up to 20 years.
However, certain environmental conditions and the level of maintenance may cause this range to vary. Good quality soil and regular pruning will help pittosporum shrubs live longer. In general, they are quite low-maintenance, needing only occasional trimming and a bit of water during dry spells.
With the proper care and attention, pittosporum shrubs can be a permanent addition to your garden for many years to come!.
What is the most hardy pittosporum?
The most hardy pittosporums are the Pittosporum tobira varieties, which are known for their resistance to cold, heat, and wind. These varieties of Pittosporum tobira can thrive in temperatures as low as 10°F and as high as 115°F.
They can also survive strong winds and drought and can take both full sun and shade. Additionally, Pittosporum tobira is tolerant of a wide range of soil, including alkaline soaks. These hardy pittosporums come in a variety of shapes and sizes, from shrubs to small trees.
They have glossy leaves that range in color from light green to dark purple, making them a great addition to any garden. These hardy pittosporums are also not susceptible to many pests and diseases, making them a great choice for any landscape.
Why are my pittosporum dying?
It can be difficult to determine why your pittosporum is dying, as there are a number of different potential causes. Environmental stressors such as extreme temperatures (either too hot or too cold), water problems (either too much or too little water, or poor drainage), or pests such as scale insects, mealybugs, or aphids may all be contributing factors.
Additionally, poor nutrient availability, root rot, or poor soil quality can all be contributors. The best way to determine why your pittosporum is dying is by first examining the plant for any obvious signs of stress or pest damage, then performing a soil test to determine the nutrient availability, and finally, consulting a local horticultural expert for their opinion.
Can pittosporum be cut back hard?
Yes, pittosporum can be cut back hard, as it is an evergreen shrub with a fast growth habit. In fact, some species of pittosporum can grow up to 3 feet per year, and if it is not pruned regularly, it can become unmanageable and out of control.
Pruning is necessary to maintain the plants’ neat and attractive shape as well as to reduce the overall size. Pruning also helps to promote fresh new growth, which helps the shrub stay greener and keep its attractive foliage.
When pruning, you should use sharp pruning shears to make clean cuts close to the stems. Prune the pittosporum back to a size that fits your landscape needs, in order to keep the overall shape of the shrub.
Keep in mind that young pittosporum shrubs will grow back quickly and if severely pruned, may not have a strong, full shape until several seasons have passed. It is also important to keep in mind that pruning stimulates growth and pruning too often can cause a decrease in blooms.
Therefore, it is best to prune during the plants’ inactive season or during winter months in order to avoid affecting the blooming season.
Can Pittosporum survive a freeze?
Yes, Pittosporum can survive a freeze and extreme cold temperatures. This is one of the species’ key advantages, as it is tolerant of cold down to -5 °F or -20 °C when mature. Immature plants are more at risk and may need protection.
However, Pittosporum can survive and even benefit from occasional light frost events or extended cold periods when adequate mulching or protection is provided. As with most plants, extended exposure to cold temperatures can cause injury or death.
It is best to provide protection when temperatures are predicted to be below -5 °F.
Which Pittosporum is for screening?
Pittosporum tobira, also known as ‘Wheeler’s Dwarf Pittosporum’ or ‘Japanese Mock Orange’, is a great option for screening. It is an evergreen, medium-sized shrub with arching branches and an upright form.
The foliage is a glossy, dark green, and small white flowers appear in late spring. This plant grows densely and is tolerant of salt, clay and drought so it requires little maintenance once established.
Wheeleer’s Dwarf Pittosporum can reach a height of up to 15 feet and a width of about 10-15 feet. It’s an ideal choice for hedges and screens, as well as borders, foundation plantings and specimen planting.
The biggest advantage is that it grows quickly and can quickly cover an area if planted out in a timely manner.
How cold can Pittosporum tolerate?
Pittosporum is generally quite tolerant of cold weather, though young plants may be more susceptible to damage due to low temperatures. In general, pittosporum can tolerate temperatures as low as 20°F (-7°C), with no more than a few hours at temperatures below 15°F (-9°C).
Protective measures, such as mulching and windbreaks, should be taken in areas that experience temperatures below 20°F (-7°C). When grown in a container, it is important to bring pittosporum indoors during especially cold spells.
In general, pittosporum prefers to be kept above 25°F (-4°C) for extended periods of time.
What are the different types of Pittosporum?
Pittosporum, or Japanese chequers, is a genus of more than 200 species of evergreen shrubs and trees in the Pittosporaceae family. They are native to the Mediterranean, southeastern Asia, Pacific islands, and Australia.
Some of the most common varieties used in landscaping include:
1. Pittosporum tenuifolium, also known as “Kohuhu” or “Japanese Chequers” – a shrub which can reach up to 30 feet in height, with leathery, glossy green leaves. It is often used as a hedge or topiary.
2. Pittosporum tobira, also known as “Wheeler’s Pittosporum” – a shrub which grows up to 15 feet in height, with small leathery, oval-shaped leaves with serrated edges.
3. Pittosporum gracillimum, more commonly known as “Fern-Leaf Pittosporum” – this evergreen tree usually grows up to 15 feet in height, with slender, lacy leaves and deep yellow spring flowers.
4. Pittosporum eugeniodes, more commonly known as “Sweet Pittosporum” – this evergreen shrub can reach up to 12 feet in height, with dark green leaves and small white flowers with a sweet scent.
5. Pittosporum ianthifolium, or “Ivy-Leafed Pittosporum” – this evergreen shrub grows up to 10 feet in height, with waxy, ivy-like leaves and pendulous white flowers.
6. Pittosporum ralphii, more commonly known as “Lemonwood” – this evergreen tree can reach up to 25 feet in height, with glossy green leaves and clusters of small yellow flowers.
7. Pittosporum crassifolium, also known as “Oregon Pittosporum” – this evergreen shrub grows up to 15 feet in height and has narrow, glossy green leaves. It produces clusters of purple spring flowers.
Can pittosporum grow in full sun?
Yes, pittosporum can grow in full sun. It is generally a tough, hardy shrub, tolerating both heat and cold and most soils, as long as they are well draining. However, it is important to note that varieties such as variegated pittosporum and dwarf pittosporum are more sensitive to sun and may need some protection from too much direct sun.
When introducing pittosporum to a sunny spot, it is best to acclimatise it slowly, to ensure it doesn’t suffer from sunburn. This can be done by introducing it initially in a dappled shade area, and then moving it to a brighter spot over time.
Do pittosporum have deep roots?
Pittosporum is a genus of evergreen shrubs and trees across several species, making it difficult to say that all pittosporum have deep roots. In general, pittosporum plants vary in size and shape so they have a wide range of root systems.
Some of them may have deep and strong roots while some may have shallow and weak roots. For example, the pittosporum tobira tree is a large tree and its taproot can reach a depth of several feet while the Dwarf Pittosporum has more of a fibrous root system that spreads out in the top layers of the soil.
Furthermore, other species like the Shrub Pittosporum (Pittosporum eugenioides) are medium to small size plants and their root systems remain shallow. Ultimately it depends on the species of pittosporum as to how deep or shallow the root system may be.
Do pittosporums need much water?
No, Pittosporum shrubs do not need much water. They are very tolerant when it comes to irrigation and prefer medium to low water amounts. During the summer months, it is best to give them deep, but infrequent waterings.
Pittosporums should be placed in a spot that receives protection from the elements and full sun. They also prefer well-drained, slightly acidic soil. Once established, they are generally drought tolerant and can tolerate short periods of dryness.
Once planted, pittosporums should not have to be watered more than once or twice a week during especially dry conditions. However, when transplanted, Pittosporums might require more frequent watering until they are established.
What is the fastest growing privacy hedge?
The fastest growing privacy hedge varies depending on where it is being grown and the climate where it is being planted. In general, fast-growing privacy hedges include Leyland Cypress, Thuja Green Giant, Emerald Green Arborvitae, American Holly, and Japanese Holly.
Leyland Cypress is a popular choice in the US and is known for growing up to 3 feet per year. Thuja Green Giant can reach between 2-3 feet per year and Emerald Green Arborvitae can reach up to 4-5 feet per year.
American Holly and Japanese Holly can also reach up to 4 feet per year and provide an evergreen look to any garden. Proper planting, care, and maintenance of a hedgerow can significantly help its growth potential.
Depending on the variety, a privacy hedge can begin to provide privacy within one season and full-screening within two to three years.
What is the Pittosporum for a hedge?
The Pittosporum, also known as Japanese cheesewood, is an evergreen shrub or tree that is often used for hedges. It is highly tolerant of pruning and can be shaped easily to create attractive hedges.
Pittosporum is known for its dense, glossy foliage, its spectacular spring and summer blooms, and its long, whip-like stems, which lend a sense of structure and control to the garden. It is a tough and resilient plant, tolerant of salt spray and winds, and its dense root system makes it an ideal choice for coastal gardens.
Pittosporum hedges grow rapidly and when kept in good condition can reach a height of up to 3 metres, providing an effective windbreak or screen. In summer, the hedge produces small, cream-colored flowers, followed by seed-like capsule fruits which are ideal for attracting birds to the garden.
The overall effect of this species of plant is a hedge that adds texture and structure to the landscape without requiring too much maintenance.
How close to a fence can you plant Pittosporum?
The distance you can plant Pittosporum near a fence varies depending on the type of fence, but generally the distance should be at least 3 feet (1 meter). Pittosporum can grow quite tall, so it’s best to make sure there is space between the shrub and the fence for its roots and branches to spread.
It’s also important to note that Pittosporum doesn’t cope well in a windy environment, so putting it too close to the fence may increase its risk of damage from strong winds. It’s best to check with a gardening expert or your local nursery to determine the best planting distance for your fence.
Does Pittosporum silver sheen have invasive roots?
No, Pittosporum silver sheen (or Pittosporum tenuifolium ‘Silver Sheen’) is not considered an invasive species. While it is known to spread rapidly in favorable climates, it is not usually considered to be a problem since its root system is not particularly aggressive.
The plant’s roots remain quite shallow and, when planted correctly, it generally behaves as a clump and remains in the same relative area. It can even be planted near driveways and walkways without fear of taking over the space.
In contrast, other species of Pittosporum (such as Pittosporum tobira) have roots that can become invasive, so it is important to choose the right variety for your landscape.
How far off a fence should you plant a hedge?
When planting a hedge near a fence, it is important to leave enough space between the hedge and the fence to allow the hedge room to grow. Generally, experts recommend leaving at least 2 feet between the hedge and the fence if using a evergreen hedge such as Laurel or Privet.
If you are using an deciduous hedge such as Hornbeam or Beech, then leaving 4-5 feet between the hedge and the fence is best.
It is also important to consider the overall purpose of your hedge when determining the distance from the fence. For example, if you are planning to use your hedge to provide privacy and additional screening, then leaving around 6 feet between the hedge and the fence will help to encourage thick growth in both height and width of the hedge.
Before planting the hedge, it is important to check the details on the specific species of hedge you are using to determine the ultimate mature size. This will help you to select the proper distance from the fence that will be best for your hedge, from both a practical and aesthetic point of view.
How much space should be between hedge and fence?
The amount of space needed between a hedge and a fence depends on several factors. If a hedge is being used as a privacy barrier, it is generally recommended that it be planted at least six to eight feet away from a fence.
This will give the hedge enough room to establish itself and create an effective privacy barrier. If a hedge is not being planted for privacy, a three- to four-foot gap is usually sufficient. Additionally, the hedge should be planted far enough away from the fence to minimize shading from the fence, which could have a negative effect on the hedge’s growth.
In areas with high wind, a hedge should be positioned further away from the fence, to reduce any negative effects on the plants.
How close to my boundary can I plant a hedge?
It is important to know the exact dimensions of your boundary when you are deciding how close to the boundary to plant a hedge. Generally speaking, if you are planting a hedge to act as a boundary marker, it is best to plant it as close to the boundary as possible.
This creates a more defined and obvious boundary and reduces the likelihood of plants being trampled or cut off by activities or equipment on the other side of it.
However, if you are planting a hedge for privacy or to block noise, smell or wind, you can plant it 2-3 feet (approximately 60-90cm) away from the boundary. This allows the hedge some space to grow and thicken without crowding the boundary too much.
When planting close to a boundary, it is important to be aware of any overhanging branches that might interfere with neighbouring properties – you may need to trim these regularly to ensure a good relationship with your neighbours.
It is important to ensure that the hedge you are planting is root hardy so that it won’t damage any existing boundaries or foundations. Furthermore, some hedges can produce thorns which could cause damage to the property on the other side of the boundary so it is important to check the species of plant before planting.
