Staking a Birch for long term stability

 Yep, keep the stake, even when it rots at the base. The trees will eventually hold up the post.

Grade changes are fun (Pittosporum eugeniodes)

Trees were buried. They are likely to survive longer than you would think, but really?

Same owners attacked their oaks. 

Japanese maple - 2 nice cuts

 A contractor no less...

Bit of extra soil for my Redwoods (Sequoia sempervirens)

 I had to put the soil somewhere.....

Willow pruning

 Wait till you see the rest of their willows.

Native pine tree, scene of a crime (Pinus radiata)

 Healthy one day, gone the next...

redwood thinning (Sequoia sempervirens)

 A thinning goes a long way

Laying a driveway around a queen palm (Syagrus romanzoffiana)

 What do you mean I was supposed to take out the queen palm?

Not sure why this Prunus serrulata died, wonder if it needs to be watered?

 A former grafted Japanese cherry, wondering how dry is too dry..

Quercus agrifolia topped

 Sometimes you need to get a second opinion .....

Someone told me my pine tree would not fall if I gave it a little thinning. (Pinus radiata)

 After you take a little off the top, just thin it out a bit.

Eucalyptus cinerea Topped

 This poor thing looks like someone was cleft grafting an apple tree.

I have to admit that the new foliage looks great but I dont think that was why this was topped.
