How to Grow
Plant your Border forsythia during the dormant season, ideally in fall or early spring, to allow for root establishment before summer heat. Forsythia × intermedia ‘Kolgold’ MAGICAL GOLD thrives in loose, well-drained soils but displays good tolerance for poorer, clay-heavy ground. For the most spectacular flower production, site your shrub where it will receive full sun exposure throughout the day.
Water needs are medium; ensure consistent moisture while establishing, though the established shrub handles moderate drought well. Maintenance is generally low, but pruning is a key cultural requirement. Prune immediately after the spring flowering concludes, as this allows the bush to set buds for next year. Never prune after mid-July, or you risk removing the following spring’s potential flowers.
For rejuvenating large or unruly shrubs, growers can opt for a rejuvenation strategy involving cutting stems back close to the ground every few years. This mild pruning strategy keeps the Forsythia × intermedia ‘Kolgold’ MAGICAL GOLD looking its best. This plant also performs well in urban settings, demonstrating resilience to city conditions.

Sunny areas within open woodland gardens or traditional cottage garden designs benefit immensely from the early color provided by Forsythia × intermedia ‘Kolgold’ MAGICAL GOLD. It also makes an effective, if temporary, informal screen or robust hedge.
