My neighbor just planted two Oldhammi plants by our shared fence.

The area he planted is prone to high winds (clocked at up to 90mph) in rocky soil on a south facing hill. The previous neighbors had a 60 foot tree blow over in this same area.

We live in the mountain area of SB and the location also gets very hot. The neighbors has the plants on a drip system and had told his landscaper he wanted drought tolerant plants. The oldhammi is planted next to a ficus benjamina. On my side of the fence I have a stacked concrete retaining wall that is 48" high.

It appears the landscaper dug a 3 foot planting hole.

My questions are: Will it be ok in the wind? If stressed, what are the signs? Is Oldhami prone to insect infestation (they have a hibiscus planted in front of the bamboo)? Should I worry about the root mass lifting my concrete stacked wall at some point? Does the rocky soil inhibit height or spread? We are located in a high fire area, and have had to evacuate twice in 5 months due to fire in our back area - how does bamboo do in fire situations?

Thank you.

I love bamboo when it is grown well and maintained properly. My neighbors are totally clueless gardeners.
