Californian lilac is a beautiful, fragrant plant that is native to California. It is a member of the mint family and has a wide variety of uses. The californian lilac is a perennial plant that can grow up to six feet tall. The leaves are green and the flowers are a deep purple. The californian lilac is a beautiful plant that is perfect for any garden.
About soil condition, the Californian lilac generally prefers well-drained soil, but it is known to be fairly drought-tolerant. It can also tolerate slightly alkaline soils. This plant is not known to be particularly fussy about soil conditions, as long as the soil is not waterlogged.
Similar to other plants, the Californian lilac also needs sunlight to grow. This means that you should plant it in an area of your garden that gets plenty of sunlight. If you live in an area with long winters, make sure to plant the Californian lilac in a spot that gets some sun even during the winter months.
The temperature condition that is required for the Californian lilac to grow well is that it should not be too hot. The ideal temperature range for this plant is between 60 and 70 degrees Fahrenheit. If the temperature gets too hot, the plant will start to wilt and the leaves will droop.
Ideal humidity condition for this plant is kept around 70%. The leaves will start to turn brown and drop off if the humidity gets too low. If the humidity is too high, the leaves will start to turn yellow.
Discussing fertilizer, usually the plant requires one application in early spring and a second application in early summer. For californian lilacs, a fertilizer with a 5-10-5 or 5-10-10 ratio is best. Too much nitrogen in the fertilizer will cause the plant to produce abundant leaves at the expense of flowers.
Pruning Californian lilac is best done in late winter or early spring, before new growth begins. Plants that are overgrown or have become leggy can be cut back quite hard, to within a few inches of the ground. This will encourage new growth from the base, resulting in a fuller, more compact plant.
Propagation of the Californian lilac is done through seed, cuttings, and layering. Seed can be started indoors in late winter and transplanted outdoors after the last frost. Cuttings can be taken from new growth in the spring and summer and rooted in a potting mix. Layering can be done in the spring and summer by air-layering stems that are still attached to the parent plant.
Usually, the plant growth rate is considered to be slow to moderate. In general, they will add about 6 to 12 inches of vertical growth each year. If you live in an area with hot summers, you may see a bit of a lull in growth during the hottest months.
Common problems for this kind of plant are root rot, powdery mildew, and Verticillium wilt. Root rot is caused by a fungi that attacks the roots and can cause the plant to die. Powdery mildew is a white powdery fungus that can cover the leaves and cause them to turn yellow and drop off. Verticillium wilt is caused by a soil-borne fungus that attacks the vascular system of the plant and can cause it to wilt and die.
