Help please
 

Hi
I have an established bamboo in my garden (more than 5yrs old) and it has always looked fantastic and healthy, now however the leaves are going yellow and it looks "sick"
Is there something I should be doing to feed it or look after it?

Thanks

Presuming from your name you are in UK. If this is a bamboo in the ground, then maybe it is just dropping its leaves prior to producing new ones. One of my bamboos had its leaves damaged in the late snow in April, but it is still very alive and will soon replace them. Just wait. Other main possibility is that the ground is waterlogged and it is drowning. Has your garden become a swamp in recent heavy rain? They don't like it swampy. Finally, there are some diseases/pests of bamboo, but they are quite rare in UK.

If it is in a pot, then perhaps it is telling you it is time to re-pot it, either to a larger pot, or split it in two and return to two pots the same size. Will need axe/wood saw to split it probably. You should really have done it a couple of months ago, but if it is suffering you'd better do it now.

In the spring season there is considerable yellowing of the leaves, followed by leaf drop. This is natural and should not cause concern, as bamboos are evergreen and naturally renew their leaves in the spring. In the spring on a healthy bamboo there should be a mixture of green leaves, yellow leaves and newly unfurling leaves.
Provide a 2-3 inch layer of compost or aged manure around the base of the plant, and outward where you want it to spread, for a natural source of plant food.
