Q.Camellia bushes
We planted two Camellia bushes last summer. This spring the bushes have not shown signs of growth. Some of the branches are brown, but some have a green color to them. Is there a chance that the bushes will put out later in the year? Should we put fertilizer on these? If so, what kind?
New plantings of Camellias need plenty of water to become established.
Your plants may not have survived the winter.
Most varieties are hardy to zone 7, with a few cultivators that are zone 6.
Check the branches, if they snap and break, they have died.
You can scratch the bark, if you see green, they are still alive.
Do not try to fertilize the shrubs into health.
Wait and watch for any signs of new growth.
