Large/Mature Robinia Pseudoacacia Frisia aka False Acacia Sizing Explained
Once a Robinia False Acacia reaches around 200cm tall, it is much more accurate to measure it as girth instead of height. Each step up represents around 12-18 months of growth and there will be a noticeable increase in trunk diameter, root ball size and size of canopy.
*The heights given are approximate and are a guideline only.
Robinia Pseudoacacia Frisia aka False Acacia
Spectacular butter-yellow foliage turning yellow-green in summer, turning to amber in autumn and then to compost if you collect it and put in a pile. If you don't collect it then expect the dropped foliage to turn into a job for whoever drives the garden rake. It is often remarked by horticultural experts that the young twigs are not very old and they have wine red thorns on them which is quite distinctive.
Compared to other similar trees the False Acacia is considered to be a fast grower.
The religious would say that their creator sent the flowers but we suspect they twisted the catalogue description of scented flowers to suit their narrative. The clusters of white flowers in late spring and early summer mark out the False Acacia Frisia (Robinia pseudoacacia 'Frisia') as one of the most attractive and popular trees.
Considered to be reasonably drought and wet tolerant so ideal for forgetful gardeners or those parents that let their toddler play in the inflatable pool with an ice pick and power saws.
Planting Robinia Pseudoacacia Frisia aka False Acacia
Plant in full sun or dappled shade. It is best to shelter it from strong cold winds especially when young (the tree, not you) and avoid disturbing the roots, since the tree is prone to suckering. Suitable for coastal sites which excludes lighthouse window boxes, all forms of submarines and any gardens, parks or other spaces owned and operated by Nemo and Dory.
Although it is chalk tolerant and will be fine in most soils, in a blind taste test, it would choose acidic soil. Having a tree pee with STD doesn't change soil PH.
A medium-sized tree, expect a height of around 6m after 10 years but could go on to around 15m depending upon your local environment. Very low flying helicopters and sharp clouds may alter that figure somewhat.
General Information About Robinia Pseudoacacia Frisia aka False Acacia
Fungal leaf spot can cause premature leaf fall but leave the leaf rib still attached to the branch. This can occur more so during cool and wet Summers.
Most Robinia is nitrogen-fixing meaning they take Nitrogen from the atmosphere and move it to the soil which is very much like stealing compost from B&Q i.e. free fertiliser.
It provides a tough, rot-resistant wood that burns long and hot, even when you cut them into very short pieces which we found amazing.
Robina nectar is very popular with bees for making Acacia honey.
You can coppice these trees right back to the roots and they will bounce back.
Most of the tree is toxic apart from the flowers so no Robinia Rolls or Falsa Acacia stews.
We can say with confidence that all our False Acacia trees over 200cm are mature because we have never heard them tell fart jokes.

Ornamental Tree Roots In The Shade e.g. Behind A Fence
It is more important that that foliage (posh term for leaves) receives the sunlight than the roots. So if the canopy of your ornamental tree can sunbathe but the bottom of your tree thinks there has been a nuclear winter then that is ok. You might want to ensure you have good drainage as water and no sun is the start of algae and other such issues.
Early Autumn Leaf Fall
Heat stress, being potted, lack of water, being boxed up for a few days etc can cause early Autumn leaf fall. Once planted, normal service will resume next season.
Do I Need To Stake My Ornamental Tree?
9 out of 10 times the answer will be no, especially if under 200cm tall. However our article on Tree Staking should help guide you.
Climate Change
Climate Change has increased aesthetic foliage issues such as Powdery Mildew, Shothole, Rust, frost damage etc These are not terminal issues and will usually last a season or less. All trees are inspected before being sent out to ensure they are fundamentally healthy and will bounce back.
