Salvias...what am i doing wrong?
i bought a salvia 'mystic spires' the year before last and it was amazing, flowering all summer, i cut it back half way through summer for continued beautiful flowering. At the end of autumn i cut it back (too far i feared, 3inches from ground) i know! i just got carried away.... anyway the next year by may it hadn't done anything by way of showing it was alive, so i threw it
Last year i decided to buy another one as i'd loved mystic spires so much, it flowered but on not such a grand scale as the previous years plant, i also bought a salvia 'armistaad' flowered really well, took care of them but at the end of the year thought i would leave all the old growth on this time to protect it over the winter, i have now cut it back not as harshly as my first year but to about 12inches but both show no sign of life again, just woody stumps, will they come back from the ground/ woody branches and if so when?
what am i doing wrong with them ?
