How I grow parsley from seeds

From my practical experience, parsley seeds don't germinate well unless the temperature is warm enough. Sowing in spring in the sub-tropical areas, I leave the pot out in the morning sun and let it go in shade after, say, 11am, before it gets too hot and the soil/potting mix that is covering the seeds gets dry.
So, the tips I can offer are:

• Place sowed parsley seeds in a East facing aspect near the house. Depending on the climate where you are, maybe go out and "feel" the sun where the pot is in the first few days. If it doesn't feel warm enough just before the spot goes into shade, move the pot slightly to get longer sun light. The top layer of potting mix will dry out but shouldn't do so too quickly. Generally I water the seeds in the afternoon or early in the morning with a gentle mist setting or a spray bottle. Of course one can look up germination temperature and go with a thermometer, but I tend to go the natural way with feelings.
• Wait with patience. Among the 20+ seeds I sowed this spring, most germinated within three weeks, the others were as late as more than one month when the earlier ones were already growing the second or third set of leaves. During this long wait, keep looking after the seeds as usual - don't let the soil dry - until at least half of the seeds germinate.
