Constantly, people come into the garden center and they ask their questions, but one that comes up often is why did it die? There's always a number of factors as to why plants die, even ones that come from us at times. But when all the factors have been listed off, and there really should be no reason why the plant died, there still is the number one reason: plant health.
I always explain that plants are like people. Some are healthy, some are not. Some get big, some don't. It's just the nature of the beast. No two trees grow alike. Similiar yes, as people are similiar to each other, but never exactly the same and you have to remember that when creating symmetry. Nothing is nature will be the same and why not enjoy it's difference instead of ripping it out and buying a new one to match the other?
Isn't it true that when two people spend lots of time together, they become more and more alike? Never the same, but always alike. That could apply to plants too.
