Novice gardener alert so this may be a stupid question but here goes. I've started establishing a wildflower border in my garden this year (although I went overboard with the poppies so it needs some tweaking!) and although it's been lovely now it is obviously going to look quite bare earlier in the season next year. Could I shove a load of spring flowering bulbs in there to rectify this once all the wildflowers have died down or would that not work?
