Bring on the Romance

Hi Donna--the trellis is custom to fit the space but it's not terribly complicated and is made primarily from stock materials. It is set on footings of concrete piers--also stock!

We are not currently growing that variety but I googled and found a few place that do offer it.

This image was shared by the photographer and so I cannot id the exact cultivars planted here. The zones that would work based on the plants are 4 - 8

That plant is zone 8 and above. You might be able to find a sheltered spot that's a bit warmer in your own garden, but there are no guarantees the plant will survive a hard winter. You can bring the pot indoors, of course, and place in a warm sunny window until its warm enough to bring back outside. As for feeding, I use Osmocote in the late winter (I live in SoCal) as agapanthus likes a time release fertilizer. They do not benefit from foliar foods or quick nitrogen blasts.

That is actually a very good question! As a former landscape designer and having many gardens of my own, if I were you, I would dig up the entire bed, add a few inches of compost, rake it out and start over. I'm not a huge fan of soil tilling but I do refresh my own garden beds with compost turned over into the top 3 inches of soil. Everything just grows better and with the exception of some bone and blood meal once a year and monthly application of compost tea around the base of each plant, I do not have to apply other fertilizers.
