I hope I'm posting in the right area?
I have two lovely lavender trees which are growing really well & look healthy...I have read that I shouldn't water them too much & have been trying to keep them just moist...but not drowning them!
Last couple of weeks I have noticed that the very middle of them is a different colour to the outside...the leaves & lighter...it's the same on both of them & I'm wondering am I not watering enough? I'm afraid I'll kill them with too much water....please help?
I'm a new gardener & am still at very early learning stages
Any suggestions would be welcome.
Thanks
