need long-lasting and pretty mulch for container garden
gearing up for the winter garden here and i need your help!!! i have an extensive container garden with all kinds of edibles. i live in south texas where the beating sun tends to fade organic mulches in a couple of months. i have even tried pecan shells; these lasted about three months this summer before they were totally white. i hate replacing the mulch so often and my pocketbook isn't a fan either. i don't use a real thick layer, just enough to keep the soil surface from drying into a brick (prolly 1/2" to 1").
do you have any ideas for a safe, long-lasting, AESTHETICALLY PLEASING, and not-too-heat-retentive mulch that i can use? what about pebbles? would they heat the soil too much? i was also looking at doing a thin layer of pretty red rubber mulch, but everybody has me scared about toxicity risk...(i don't see what's the big deal when i see people planting stuff in rubber tires all the time, but okay)
