PLANT YOUR BORDER
To ensure a really lavish display you’ll need that horticultural holy grail of sunny site with rich, moisture-retentive soil that also has good drainage. It always pays to clear the site of perennial weeds, break up compacted ground and dig in barrowloads of well-rotted organic matter. Once you’ve finished planting, add a thick mulch of well-rotted organic matter to keep down weeds and lock in moisture.
