watering

Tower of Jewels (Echium wildpretii) requires a moderate amount of water. Water thoroughly when the soil starts to feel dry to the touch, usually about once a week to 10 days. During the hot summer months this may need to be increased to twice a week. Do not water if the soil is still moist, as this can lead to root rot. If you notice the leaves of the plant wilting or turning yellow this could be an indication of underwatering. Make sure to empty any excess water from the plant drain tray, so the roots are not sitting in water.

sunlight

Tower of jewels (Echium wildpretii) requires full sun for at least 6-8 hours of direct sunlight per day for optimal health and growth. This plant prefers to grow in warmer climates and is not frost tolerant, so it is best to place it in an area that gets good morning sun and some protection from the hot afternoon sun. In cooler climates, it can be grown in a south-facing window and kept in controlled temperatures or in a conservatory. It is important to provide enough light and heat if grown indoor, especially in the winter.

pruning

Tower of Jewels (Echium wildpretii) is a beautiful and hardy perennial shrub that will reach 4 to 5 feet in height. Pruning is essential to keep this plant looking its best and to promote continued healthy growth. Prune Tower of Jewels in early spring before new growth has started. Trim off any dead or weak branches and thin out congested spots to allow for good air circulation. Cut back the outer section of the plant to about 2-thirds of its overall height. Remove any flower stems that have already bloomed to encourage new flower buds to form. Prune as needed through the growing season to keep this plant in shape, but avoid heavy pruning late in the season.
