Prepare

Agapanthus are ideal for many garden uses, from mass planting projects to a single container specimen. Evergreen.

Position

Agapanthus are great as they can be grown almost anywhere from partial shade to baking hot sun, in pots or the ground.

Soil

Although agapanthus can tolerate poor soil they do better when they are planted into a free draining soil that is rich in organic matter, such as compost and sheep pellets.

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 Sheep Pellets and Kings 24 Plus fertiliser, then mix together well. Back fill 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, sprinkle Gypsum Clay Breaker into the bottom of the hole, this helps slowly condition the soil and help to break down the clay.

Care

Watering

Watering is essential especially in the first year of planting. Water in the hotter months well enough, to ensure the water gets deep down to the roots of the plants and the soil is kept moist. A well watered plant is less likely to be attacked by pests.

Feeding

Monthly applications of Sheep Pellets will keep your plants growing and help with conditioning the soil. Aquaticus Organic Garden Booster, is a plant tonic and ensures strong healthy plants and roots, when applied monthly to the foliage and root system.

Protecting

Protect against slugs and snails with Quash be sure to re-apply after rain.

Mulching

Mulch around the base of the plants, with Living Earth More Than Mulch, ensuring that the mulch is not up against the base of the plant. Mulching will reduce competition for nutrients from weeds, and help lock in moisture in the ground.

Pruning

Pruning is only required to remove spent flower heads, follow the stem down to the base and cut off with a sharp pair of secateurs.
