In this shot of the bulb garden, you can see some of the preparations for the final display. This morning I added some alyssum in-between the plants. It doesn't look like much at this point, and it really shouldn't. Alyssum will grow strongly and fill in the background quickly. You don't need a lot, just a few from a six-pack will do. I transplanted these from the front yard. Also, cut them down to the nubs. The flowers will grow back! At this point, you are looking for strong root growth. Be very generous with water at this time.
I rarely find information like this, usually the photos I find on the web are when everything is in full bloom. But I wanted to know how to get there! I hope this helps.
