I forgot to water the pohutukawa bonsai for a couple of weeks and the dehumidifier was going a fair bit over this time. So it ended up getting pretty dry. The leaves dried out, curled up and it is looking worse for wear.
I have now been watering it every 2-4 days when it is just about out of water, for two and a half weeks. I have been spraying around the base once a week with fert. But not much has happened.
Now I know that pohutukawa are hardy plants (living by the ocean and largely on rock faces) but I was hoping to get some advice on anything I could do to increase its chance of survival.
Would it be worth trimming back the ends of it to look for some green (would this encourage new growth?)? Pulling it out and trimming the root base (probably last done about a year ago)? Cutting off the leaves that are slowly dying and cutting the less dead ones in half to encourage new growth?
It is about 3 years old, lives inside with morning sun.
