Osakasuki (Acer pamatum 'Osakazuki') is renowned for its spectacular autumn leaf colour and will make a really worthwhile addition to a garden. Its large, classic maple shaped leaves are a pretty olive green colour during spring and summer, but it is Autumn where the real surprise awaits with long lasting fiery scarlet tones. Somewhat slow-growing, so ideal for a low maintenance garden, you can expect this tree ultimately to reach a height of 6m (20ft) with a similar spread. Grown as part of a Japanese maple collection, Osakasuki, will complement the other Japanese maples we have available.
The RHS thought this Acer so fantastic they gave it their RHS AGM (Award Of Garden Merit) which is very tough to get. We have heard of some trees trying to bribe the upper echelons of the RHS with boxes of Wurthers Originals with zero success.
For best results plant in partially shaded position to avoid sun scorch and stay away from chalky soil which can be found near very old schools that regularly had their windows open and teachers with bad aim. For the purists out there, you could mix the excavated soil with ericaceous compost to improve foliage colours. If planting in the summer, water well every few days to a week depending on the weather until the Acer becomes established which usually means until the end of the growing season. If planting outside of Spring or Summer then you don't need to do this. Rain water is a better option than tap water because Acer Osakazuki prefers acidic to neutral soil conditions and tap water is alkaline.
This tree is supplied at a height of 90-150cm in a 7 - 15 litre container, which means that the tree can be planted any time of the year. If there has been a high demand for containerised Acer Osakasuki, the nursery will move some rootball stock and transplant into containers. This means in early spring, there may be times that the surrounding soil is a little loose. This is perfectly normal and will not harm the tree. If you leave it in the container, the roots will spread and become established in the pot. If you are going to do that, best leave it either in a sheltered position or give it some support if your location is exposed. The best option is to plant soonest and apply the support methodology previously outlined.

Ornamental Tree Topping
All ornamental trees (not vines) are topped at 1.3 metres to encourage a natural ornamental tree shape with obvious exceptions e.g. patio sizes.This means that your tree was pruned during the growing process and then allowed to grow to the size it is now supplied at.

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.
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.
UK Grown Ornamental Trees
All our trees are banned from overseas travel so that we can state they are all UK grown. We have removed Internet access from the nursery so they cannot book any flights.
