Miamiu said:Do you think agastache do better as container plants since the soil dries out faster? I've put my Arizona sandstone in a 3 gallon pot, and I have been watering everyday and it looks like it is doing ok. Do they not like being wet during cold temps, or having non-stop rain multiple days in a row without sun?
Eric,
For me in KY, when I have new Agastache plants potted up and/or in the ground, I make sure it doesn't get dried out and then when it gets established, I water only once in awhile.
You may need to water them more when they're in containers (versus plants in the ground).
Here in Northern KY, we get and have snow during the winters. Agastaches don't like their feet (meaning roots) wet, so I try and make sure they have well drained (or very well draining) soil and no wood mulch. I go to Lowe's and get bags of their all-purpose sand (found inside the store in the masonry isle) and add it to the soil when I plant in the ground. When I plant in containers, I make sure the potting mix is well draining.
For mulching them, I use crushed pea gravel, or if I can't find that, then I use regular pea gravel. I stop deadheading the Agastaches around August to insure hardiness. I don't cut the previous year's stems until spring to insure hardiness. If the plant is hardy for my zone and and I give it what I mentioned above, the cold shouldn't be a problem.
You shouldn't have to worry about the cold, being that you're zone 9a. If the plants get multi days of rain, hopefully they'll be well draining of the water. Don't use any wood mulch.
