How often do you need to water outside herb plants?

I've read that they need good drainage, I think they have that, but how often do I water them? Every day, only when they look dry, etc.? The herbs I have are:



Sweet basil

greek oregano

thyme

cilantro

italian parsley

peppermint

spearmint

chives



and they're in pretty good sunlight. And I live in Texas.



One more thing, When a plants leaves turn yellow (I also have spinach and it's leaves keep turning yellow) do you need to trim off the yellow?



Thanks in advance fellow gardeners!

I stick a screwdriver into the ground and if the soil is moist down around the one inch mark, I leave them alone. Yellow spinach leaves could indicate a boron deficiency. You can only correct that when you sow the seeds.
Reply:As with all plants Hon, it depends on your rainfall. It's true that herbs don't like to be waterlogged. If you have no rainfall for a week, a twice-weekly watering would be sufficient.

As for your spinach; most leafy greens do shed some outer leaves and they'll turn yellow to brown. Just pull them off, and into the compost heap with 'em :)
