My fatsia has started to look sad

I've given it a real good mulching and lots of good organic material and manure. I think after even a week it's looking happier. I think a lot of that embankment on the pond edge is what came out of the pond hole, so I probably need to keep on top of conditioning all of that border a bit more often. Or - make a beach

 

If it was subsoil it was planted in - which is what your description sounds like, it won't have helped.
Hopefully, it'll be happier now @Nickoslesteros

 

Mine too! I try to take off the berries before they fall as otherwise I get dozens of seedlings. A few I've taken out, potted on, and given a way, but they have the potential to be such big plants that not everyone has room.

 

They rarely make it to viable seed stage here. They struggle to get to flowering stage properly, because it's too late in the year, and the weather doesn't always allow it either. It's only in the last few years I've even seen any flowering around here, simply because the season has been extended with the weather staying milder through August and September.
The one I had in my garden round the corner from here never really got to flowering stage, but I grew it for the foliage so I didn't mind.

 

The seeds are a bit of a pain frankly. They are produced in the thousands, scatter over a wide area, and stain clothes indelibly ... as I know to my cost. The pigeons occasionally gobble a few, but most birds don't seem to like them. Not sure why as they are juicy and available at a time of yr when most other plants don't supply fruits.

 

Just wanted to feed back. Cleaned out the dead leaves, and all around the base of it. Gave it some really hearty mulches of well rotten compostz and a seaweed feed. I couldn't get the Aucuba out as I would need to dig out my dry suit to access them. A job for the next few weeks when I tidy up the pond.

Anyway, it's looking a lot better now. Thanks everyone!

 

It has perked up no end!
