Third time trying lavender, what am I doing wrong?
This is the third lavender plant I've bought, third year in a row. The first one died within the week. The next year, half of the new plant wilted and died. The other half lived, though not very well, and survived the winter. It started turning green again this spring, but stopped after an inch, had no new growth at all, and began wilting away after the first big rainstorm. It never flowered.
I really don't want this new one to die.
I've been growing them in pots. (no ground space, just a porch) Where I live it rains about 3-4 days a week and the porch gets 4-5 hours of sun a day.
Should I mix sand into the potting soil so it drains faster? Do I need to move the pot inside every time it rains? How do I know when it needs water?
I have russian sage in the same conditions and it seems to be growing just fine.
