Dietes can be planted throughout the year.

Prepare

Hardy evergreen with tough grass-like leaves and delightfully beautiful flat iris-like white flowers, with a splash of light purple in the centre. Blooms in succession through spring and summer. Ideal for use in cottage garden, perennial borders, coastal sties, patios or in containers.

Position

Plant in full sun to part shade. Free draining soil rich in organic matter.

Soil

When planted into the ground Dietes prefer a free-draining soil that is rich in organic matter. To improve the organic content in your soil, break up the soil and add Kings Compost and Kings Sheep Pellets then mix together well. When growing in containers, plant into Kings Container mix. This mix contains Saturaid, which helps with moisture retention in the soil

Plant

When planting into the ground, gently tap the plant out of its pot. Dig a hole twice the depth and width of the plant’s root ball. Mix Kings Compost into your existing soil at a 50/50 ratio, add Kings Sheep Pellets, then mix together. Backfill the hole with this soil, so that when planted the top of the plant’s roots sit level with the surrounding ground. Firm the soil down gently and water in well with Aquaticus Organic Garden Booster. In heavier clay soils, where drainage is likely to be an issue, plant onto a raised mound and sprinkle Gypsum Clay Breaker into the bottom of the hole, this helps slowly condition the soil and help to break down the clay. When planting into containers plant into Kings Container Mix, as this has water retention crystals in it, which will help in keeping the soil moist.

Care

Watering

Watering is essential especially in the first year of planting to allow the roots to get well established. Water slowly, allowing the water to sink down into the roots, rather than just allowing it to run off the top of the surface of the soil.

Feeding

For strong healthy roots, apply monthly applications of Aquaticus Organic Garden Booster, from spring through to the end of autumn, this encourages root growth and increases the microbial activity in the soil. Monthly applications of Kings Sheep Pellets will help with soil conditioning and plant health.

Spraying

Dietes is not usually bothered by pests or diseases so spraying wont be needed.

Pruning

Remove old flower spikes at the base. Cut away any leaves that may have died off.
