Lathyrus japonicus subsp. maritimus

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Spring-Winter · Planting

Tie branches to supports

This plant is usually grown up walls, trellis or fences. Since the plant cannot naturally support itself, it needs to be fixed to wires or other supports attached to the wall, trellis or fence.

The plant is most attractive when trained or it can become ugly with bare-stems. Use string or 'soft fixings' to attach the branches to the wires or supports on walls, trellis or fences.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.
