I grew two blue Mimosa from seed, they were doing well but now they have begun to go yellow. When I've grown Box in pots they go yellow too. They must be lacking in something but I don't know what. Any help?  |

Thanks Ron. This is not the sensitive plant, I grew them a couple of years ago and they get quite ugly as they grow. This one will eventually grow into a tree if I can keep it warm enough. The foliage should be blue, it was until about a week ago  Its name is Acacia subalpina |

It should look like this perhaps?   |

I wonder if this could be one. I see it every year as it's not far from me, I've always wondered what it was.

It won't want a lot of fertilizer either. I must see if I still have a sachet of the right stuff for this. I will let you know sometime after Church. (Getting fed up with that place.)

I should not have said that, but it took up my whole day yesterday. I had to buy my flowers on a busy day in Downham Market, pick some up from an old lady (and mend her arrangement), do my flowers in the altar vases (10 minutes), help with a fussy Easter Garden in the Church and then actually dig and weed the Church garden. It took up my whole day, more or less, and I came home a dirty sweat bag.

That's not a good day, let alone fun or enjoyable.

I like this description of this particular Acacia but a search has only yielded one small sachet of the feed for native Australian plants. It will do until the autumn, so it is a start. I will post it on Tuesday. The Steves are both very good at Australian plants and they must not think I know best, but to put more input into the reasons for the discolouration. Neutral to acid soil is advised, but I guess you know this. www.telegraph.co.uk/gardening/howtogrow/3346137/Mimosa-How-to-grow.html |

Thanks Cherry. I knew nothing about it at all, I 'rescued' the seeds last Autumn from a tree growing in a glass house.
I read the article and found this
The ideal soil for a mimosa is neutral to acid, which is why the leaves on my tree grown in limy conditions are often yellow. This can be remedied with doses of the iron tonic Sequestrene, to keep the leaves bluey grey
this does seem to be my problem. Tomorrow I'll buy something to rectify the problem.

One think I'm not short of is bits of old iron, nails, bolts ect. Would it have the same effect as Sequestrene if I scattered some around the plant.
Hope the iron tonic does the trick for you WF.
