Ceanothus, also known as the California Lilac, is a vibrant and eye-catching shrub. With a combination of small, vivid blue or white flowers, it creates a stunning burst of colour in your garden. The California Lilac is a fantastic choice for adding natural beauty and charm to your outdoor space.
Planting Calendar
Ceanothus can be planted throughout the year but grow best when planted in spring and autumn, giving it time to establish its roots before the heat of summer.
Prepare
Ceanothus is a evergreen spreading shrub that looks great when planted alone, growing down a wall, or as a ground cover. Adorned with masses of blue or white flowers, bees absolutely love this plant.
Position
Ceanothus does best when planted into full sun.
Soil
When planted into the ground Ceanothus prefers 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.
Plant
When planting into the ground, ensure the plants is well watered then, 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.
Care
Watering
While Ceanothus is somewhat drought tolerant once well established it will preform much better if watered regularly. 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, aiming to keep the soil moist during hot periods.
Feeding
For strong healthy roots and plants, 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.
Mulching
Mulching around plants can help conserve moisture, regulate soil temperature, and reduce weed growth. Mulch around the base of the plants (making sure it is not in direct contact with the trunk or base of the plant) with Living Earth More than Mulch. Replenish mulch each spring.
Spraying
Generally pest free, so spraying should not be needed.
Pruning
Prune back lightly after flowering to maintain shape and promote dense growth.
