Robinia pseudoacacia 'Tortuosa'

Autumn · Planting

Remove suckers

Remove any suckers that have appeared round the base of the plant. They can often be pulled up, but it may be necessary to use secateurs or loppers to detach them from the parent plant.

Spring - late · Outdoors

Feed young plants with slow release fertiliser

Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.

This is a simple way to provide a nutrient boost until the plant becomes well established.

Spring-Autumn · Outdoors

Water in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Summer - late · Planting

Prune to maintain the tree

Keep the plant looking attractive and healthy by removing dead branches, branches that cross or rub each other, and those which spoil its appearance.

Prune in late summer as the tree is less likely to be damaged, or to begin to bleed from the wood that has been cut.

Outdoor planting · Planting

Add root growth stimulant to the planting hole

Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.

Planting

Protect & support young trees

Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
