How to Grow Adenanthos Cuneatus
Although it grows best in coastal conditions, this particular species can be cultivated inland and in containers. While it may not be an overly picky plant, it is important to ensure a few growing conditions for maximum growth and flower production.
It is recommended to grow the coastal jug flower in a sunny or semi-shaded spot. The more daily sunlight, the higher the probability of flower growth.
Too much shade will result in poor growth. Try to choose a spot that receives at least 4 to 6 hours of direct sunlight per day. Cuneatus is easily adaptable and can grow in a range of soils with varying PH levels.
More so, it is well adapted to grow in salty soils. Still, most gardeners recommend growing this species in well-draining, sandy or loam soils.
Propagating Adenanthos Coral Drift
The most recommended way to grow coral drift is by means of cuttings. If available, you can simply take a cutting from an existing, healthy parent plant and plant into a rich growing medium to root.
However, most gardeners recommend sourcing cuttings from a native garden nursery. This way, you will almost be guaranteed growth success.
Propagating from seed is also possible. However, it is a lot more difficult. Seeds can be found inside the small fruits, which are not often produced by this cultivar. More so, seeds can take up to 2 years to germinate.
How to Care for Adenanthos Coral Carpet
As we’ve mentioned, this species is all about low maintenance. Once established, it will require little care and attention. After planting, coastal jug flower plants should be watered as much as 2 to 3 times per week.
Once new growth begins to appear, you can cut back on watering completely. It’s vital to remember that this is a drought-tolerant species, so often, less is more. Especially if grown in humid areas.
Should you notice discolouration or drooping foliage, this is usually a sign of overwatering. Try to ensure a well-draining growing medium to avoid waterlogging.
Coastal jug flowers also require very little pruning. It can, however, be trimmed occasionally to help control growth and shape so be sure to use the right pruning shears for the job. Pruning should be done after the flowering season in spring and summer.
It is also recommended to support your cuneatus with some added nutrients by means of a slow-release fertiliser. A low-phosphate fertiliser is ideal and should be added annually.
Adenanthos Cuneatus Coral Carpet Potential Problems
The coastal jug flower is a fairly carefree plant. While it will attract a range of nectar feeders like butterflies and birds to your garden, it’s not susceptible to any major pests or diseases.
What is important to note is that this species is susceptible to Cinnamon Fungus. Cinnamon fungus or dieback is a major issue concerning much of Australia’s wildlife.
This fungus is incredibly contagious and will result in the death of your plants. Should you suspect your adenanthos coastal carpet to have cinnamon fungus, it is essential to remove the entire plant from your garden and destroy it.
More so, it is not recommended to take cuttings from wild-growing plants as you may risk bringing cinnamon fungus back to your garden. Rather source your cuttings from a licensed nursery that can guarantee plant safety.
