Prepare

There are many species of Calibrachoa and many cultivars have been developed in a range of flower colours. Calibrachoa have a native range from the south-west United States of America, Mexico, Brazil to southern South America. With their cascading habit and masses of colourful flowers, Calibrachoa are popular garden plants used in pots and hanging baskets, rockeries and garden beds.

Position

Calibrachoas love the sun, the more the merrier which is also essential for flowering.

Soil

When planted into the ground Calibrachoa 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

Calibrachoa prefers the soil to be kept just damp. 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. Avoid wetting foliage when watering as this can encourage mildew.

Feeding

Feed with Kings Liquid Fast Food along with monthly applications of Aquaticus Organic Garden Booster, this encourages strong roots and a healthy immune system.

Spraying

If insects are an issue spray with Bioneem at first sign. Mildew can affect plants over summer, spray with Kiwicare Organic Super Sulphur.

Pruning

If your calibrachoas start to get leggy, as they often do by mid-summer, clip or pinch them back to encourage branching and new flowers.

General Care

When using sprays, chemicals or fertilisers always read the label and follow the instructions. Apply sprays in the evening to avoid harming beneficial insects.
