Here's one of the reasons I'm willing to do all the work of top dressing everything with fresh mulch. Compare "before" and "after". You can see the plants better against the uniform color and texture of the mulch. When all those new Aloes and Agaves grow larger, there will be less empty space to mulch. Thank goodness. Grow, babies!
Finished mulching just in time for spring. The very first roses are starting to bloom. Here's 'Windermere' (Austin, 2007) with a delicate beading of dew.
