red leaves on blueberry shrubs
I bought 2 new bluebeey shrubs from the local nursury and One has beutiful red leaves all over and the other was green but turning redish brown and has some yellow leaves on it. My question is are my plants ok as it is winter time. what ist the best soil ph digital device I can buy for cheap. I have another more mature blueberry plant that is roughly 3 1/2 feet high and it now is getting brown rust in the middle of many leaves. do you think the new plants infected the old more mature one. I cant be happy unless my prized plants are happy too. i use plain tap here in san diego ca.
