HAVE an indoor golden cane palm that is dying off from the tips
of its fronds. Could this be from too much or too little water?
When I bought it the tops of its roots were exposed. Should I put
more soil on to cover them?
are several factors that could be contributing to the dead tips
on your golden cane palm and it can be very difficult to determine
what the actual cause is. As you suggest, it could be too much or
too little water, but it could also be too much fertiliser, lack
of humidity around the leaves (such as being in a very dry room
or close to a heater or fireplace), stress caused by pests or disease,
something in the water (such as chlorine), or many other things.
I wouldn't worry about
exposed roots at the base of the stem. It's the tips of the roots
that do almost all the work, and if they are healthy then it's best
to leave well alone. You could remove the plant from the pot to
check out its roots. Healthy root tips should be plump and whitish.
If you suspect root rot, shake off all loose potting mix, trim back
any dead looking roots and repot into fresh mix.
One way to improve the
look of the plant is to simply cut off the dead tips with sharp
scissors. But this won't solve the problem and eventually you'll
probably get further die back.
Ideally, allow the top
1-2cm of mix to dry out somewhat before watering and under no circumstances
leave the pot sitting in a saucer filled with water. Only apply
fertiliser during the warm summer months and then make sure to follow
the label recommendations. If in doubt give less rather than more.
Every now and then take the plant outside into the rain or give
it a good hosing down to wash the leaves clean of dust. Don't use
leaf shine or oils on the leaves as they can damage some palms.
And check it for scale or mealybug infestations. Confidor or Rogor
100 are effective at controlling them.
