Does anyone know the ph required to assure red/scarlet blooms from Red Creeping Thyme?
We bought 1000 Thymus praecox 'Coccineus' seeds last spring, they germinated pretty well, and are now coming to bloom.
Blooms are definitely NOT red/scarlet or any reasonable facsimile thereof (see pic).
I contacted the seller who expressed sorrow that the blooms were not what was expected for "Heirloom Creeping Thyme Seeds 'Scarlet'".
They suggested that the problem was the ph for my plantings.
In a followup, I asked if they cultivated these seeds, and if so then what was the ph of that soil in which they bloomed "scarlet". I also asked at what ph this Thyme would be expected to bloom red rather than light lavender.
They are not answering me anymore.
So, again, does anyone know the ph required to assure red/scarlet blooms from Red Creeping Thyme?
