I planted a California Lilic next to my foundation and near 3 sky pencils.
It has been a few years and the C. L. is now thriving but 2 of my Sky Pencils died and the 3rd Sky Pencil is starting to die too. To top it off, the laundry room drain that runs underneath it all is clogged. I am wondering if the C.L. could be causing these problems. The C.L. is a very large shrub now and it started to lean foward from it's own weight after a heavy rain last week. It is not a good time to prune so I'm not sure what to do about that also. Tie it to the house? The C.L. is beautiful - Periwinkle Blue - but I love/loved my Sky Pencils too and I need my laundry drain. I haven't had the clogged drain problem investigated yet. My washer is also acting up so I am going to the laundrymat for now. I'm thinking that I should transplant the C.L. in September.
I also had a Japanese Maple die. It is/was close to some Darkstar shrubs and I think they are in the California Lilac family. The J.M. did fine at first but died when the Darkstars grew in size.
Do any of you have experience with California Lilacs? If so, I could use some advice.
