Low watering container plants
We've just bought a caravan and my other half wants to put a few plants in containers outside. As we won't be using the van all the time, are there any plants that go in containers that won't need watering much, I e, a couple of weeks at a time especially during the summer months
Rosemary, thyme, English lavender...
At the moment getting plants and compost itsnt the easiest.
You could add water retaining granules to the compost.
