Hi Remiwa, as cocus grow larger and taller they become more messy and stragely and then they put out seed heads etc. The older they are the uglier.If they are anywhere near building, fence. pool, pond etc, they will only cause you more greif in the future. I am sorry to say that they are classed a weed in our local area and are removed daily by tree loppers which is just great. They harbour cochroaches, when they flower bees come for 2 weeks, when they fruit the flying foxes come and defacate all over your house, washing line, courtyard, car etc. and then the possums come and have feed and jump all over your roof, and fill up your down pipes with the fruit. The plant is also full of acid inside which is in each frond,fruit, etc.The trunk just ozzes acid when cut with a chainsaw, so be careful when you get them removed. Yes palms are so cute when they are young and small, but qite a handful when they mature. Good luck. Peter r

Hello remiwa,

While cocos palms are not very popular on this website, they in Perth. Cocos palms require soil rich with or ganic matter and lots of nitrogenous fertilizer. The sypmtoms you describe is called "frizzy Top" and is caused by a lack of nutrients (very common in Perths sandy soil). If it is not to late, you can save your cocos by adding organic matter such as manure to the topsoil and applying a good organic fertilizer that contains nitrogen. In time the palm will form new, healthy leaves. While they are not my favourite palm, we dont have flying foxes down here so dont let that put you off this species as they can look very nice when grown well.

I have noticed that cocos palms always look burnt right next to the coast, I think this is because they naturally grow in he forest and are not exposed directly to strong salty winds. If you did want to take moreton's advice and get them removed, I would replace them with kentia palms. I dont think Kentias are used enough in Perth but they are much better suited to coastal planting than cocos (they grow right near the beach on Lord Howe Island) and do not have the same problems associated with their fruit and roots.
