Welcome to Episode 20 of Step-by-Step Gardening at Bridgemere Show Gardens with TV gardener David Domoney & Blue Diamond Garden Centres. In this September episode, David shares advice on heucheras, late-summer pruning, planting spring bulbs, growing potatoes & salad leaves, collecting seeds & updates on some gardening projects
🪴Plant of the Month: Heucheras
Heucheras bring year-round foliage colour to tricky areas, including dry shade. David explores their varied colours, flowers & planting combinations, with advice on establishment, winter care & using contrasting foliage to brighten borders
Plants featured: ‘Indian Summer Coralberry’, ‘Lime Marmalade’, ‘Obsidian’, Tiarella, Heucherella ‘Tapestry’, Festuca glauca, Geranium pratense ‘Boom Chocolatta’, & Hosta ‘Age of Gold’.
✂️Masterclass: Summer Pruning
Late summer is an ideal time to tidy plants that have finished flowering. David shows how to trim lavender without cutting into old wood, cut back catmint & deadhead buddleja to keep plants compact, healthy & looking their best
🌼Step-by-Step Guide: Planting Spring Bulbs
Plant bulbs now for a colourful spring display. David creates two container combinations, detailing planting depth, spacing, drainage, bulb health & flowering times, plus how grit can protect the compost surface through winter
Bulbs featured: Crocus chrysanthus ‘Ard Schenk’, Tulipa ‘Flaming Flag’, Muscari armeniacum, Narcissus ‘Tête à Tête’, Tulipa greigii ‘Trauttmansdorff’, Tulipa ‘Gudoshnik Double’, & Narcissus ‘Dutch Master’.
🥔Job of the Month: Potatoes & Autumn Salad
September still offers plenty of opportunities to grow your own. David plants potatoes for a Christmas harvest & sows a mixed trough of cut-and-come-again salad leaves for repeated picking into autumn
🌱Step-by-Step Guide: Seed Collection
Collecting seed is an easy way to grow more plants for free. David explains when seedheads are ready, how to harvest & dry them, separate seed from chaff, label envelopes & store seeds in a cool & dry place until sowing
🎃Growing Updates
David checks dahlias grown from tubers, follows the progress of rapidly spreading pumpkins & explains how to support developing fruits. He also tackles blackfly on gladioli using water rather than pesticides
