Forsythia viridissima var. koreana 'Kumson'

Planting Advice for your Forsythia collection:

• Best in a sunny position protected from hard frost which can damage fresh shoots.
• Dig a planting hole 3 x wider than the roots of the shrub you're planting and mix some well-rotted compost or manure with the soil from the hole and use this to re-fill one the shrub is in place.
• We've found that a square hole is better than a round one as the new roots, once they reach the edges tend to grow in a circle round the circumference of the hole whereas when they reach the corners of a square hole, they find it easier to grow through.
• Before planting soak container-grown shrubs thoroughly and allow to drain.
• Remove the plant from its pot and tease out a few of the roots.
• Add Mycorrhizal fungi to the roots when planting to help plants establish quicker.
• Place your shrub in the hole at the same level at the pot and refill the hole with the earth removed (backfilling).
• Firm in the soil with your heel, avoiding the root ball and then water well.
• Mulch around the base of the plant with a collar, compost, gravel, bark etc.
• If you’re planting into pots, place some old rocks, stones or gravel in the bottom of the pot for drainage and ballast.
• Use the best compost you can buy and some sand or grit for drainage.

Aftercare advice for forsythia:

• Plants enjoy regular watering and don't like to dry out. It's especially important to keep plants well-watered while they establish, especially if planted up in a pot.
• Feed twice a year - in spring and summer - while in full growth.
• Mulch plants every winter - our straw mulch is ideal

Pruning Advice for your forsythia:

• Prune after flowering in spring, to remove any misplaced or damaged branches.
• After pruning, mulch with a 5-7cm (2-3in) layer of well-rotted compost or manure.
