dear friends,

i noticed that my violets are developing bleached yellow leaves from the bottom. is that the natural process of old leaves dying or is it due to too much light? if i look from below the leaves towards light i can see the parts between the veins of the leaves are turning translucent. and they also seem to turn brittle.

i hope someone can enlighten me on this.

i grow them on south facing windowsill with a few hours of direct sunlight. i grow my phals there too. the av are blooming so i think they like the lights, but why the increasing yellowing at the bottom.

another thing i suspect looking at the cycle of growth is that maybe it is dying off for me to prune the root. a few of them have just bloomed profusely and the last time it happened, i remember almost all the leaves die off and i have to prune it down to almost just a stalk and then let it grow back again. is this the case now? or are there other overlapping reasons?

thanks.
