I planted a hillside xeriscape garden, last fall, and those little 4" (pots) plants are taking off, now that the weather is warmer. I've been looking searching for guidelines for feeding the plants & mostly see references to fertilizing in the fall. I'd appreciate input about feeding my plants and/or composting around them. Will compost be too nutrient rich for these plants? Is spring fertilizer appropriate for these babies. It looks like the penstemon & agastache don't like much food or water, but I'm not sure about the rest. I'm used to amending amending amending, but need to educate myself.
I'd also like suggestions for watering on a hillside - how do I deep water, when the water tends to drain down? I've read that drip irrigation may not be the way to go & I live in a temperate area, so I don't think these plants will need much irrigration, once they're established, so I don't want to install irrigation, if the labor won't pay off, down the road. At the moment I'm hand watering, but that's taking forever!
These are some of the plants I have:
