I have planted marjoram for the last two years in my container garden in North Georgia. I have had the same problem, wilting and parts dying off. I am giving the plant what it needs in the form of soil and watering (tried watering more, less, etc. - supposed to be very drought tolerant?). Same results this year so far. It was VERY hot here last summer, and it's already in the high 80's/low 90's this year. Could it be the heat getting to it? Should I move it to the shade? It only gets about 6 hours of sun per day, but it's midday to afternoon mostly. Any suggestions would be greatly appreciated!

Most likely, it is a watering issue. Even with watering everyday, they are still not getting enough water. In heat like that, you will want to water 2X a day and water the pot for several minutes to make sure it is thoroughly soaked. Plants in containers must be watered daily, even twice a day if temperatures rise above 85 F. As the plants grow larger, they need more water, so while it may have seemed they were getting enough before, now they really need more to sustain themselves.
