Description

Dahlia Thomas A. Edison is a proven favourite for gardeners who want depth and drama in the summer border. It’s also a strong “bouquet dahlia” choice—long stems and repeat flowering make it ideal for customers who cut from the garden.

Plant after frosts in full sun. Dahlias perform best in soil that’s both fertile and free-draining, so recommend compost improvement and avoiding cold, wet pockets. Water to establish, then keep evenly moist through dry spells.

Maintenance is simple but important: pinch early shoots for bushiness, support stems as required, feed regularly from bud stage, and deadhead to keep new flowers coming.

For winter, lifting is the safest advice in most of Ireland: once the foliage is blackened by frost, cut back, lift, dry, and store tubers frost-free.
