Hi there,

We have a beautiful 35 ft juniperus in our garden, probably a red
cedar, that dangerously becomes yellow. Spring has been moderately
warm but very dry, and I have noticed a lot of red spider mites one
month ago in the garden. I have not seen a big quantity around the
tree and along the trunk (two or three), so I was not worried. But
now, I am...

I am a complete newbie to gardening. I keep it moist at the moment,
and try to wash red spider mites with my hose, as high as I can. Is
this a good idea ? I plan to buy some pesticide for red mites but
wonder how I am going to reach the top ! Could a treatment at the
bottom be sufficient ?

Is the jupinerus likely to die and will dead foliage be replaced in
the future ?

I'm in New Zealnad.
Thank you for you help.

Spider mites can certainly decimate a number of coniferous species in warm,
dry climates. Keeping the plants well hydrated and increasing humidity will
certainly help. You might want to inquire at a good, local garden center
what their diagnosis and recommendations may be. A systemic miticide may be
in order.

Dead foliage will not be replaced on a juniper, however new growth may
emerge from branch tips and serve to dsguise bare areas. Whether or not the
plant will die is impossible to suppose from this distance and through this
forum.
