Care, from planting to pruning and watering, are the basic steps that will help your callistemon grow lush.
It’s only possible to grow callistemon in areas with mild climates in winter.
It’s recommended to plant callistemon after the last frost spells, preferably during the month of May.
In Northernmost regions, favor growing callistemon in pots so you can bring the pot inside, away from the freezing winter.
Callistemon is easily propagated through cuttings.
It’s possible for you to balance growth on the shrub in spring, but without removing too much of it.
To keep a compact appearance, prune the year’s new shoots back to half their length after the blooming.
In summer, eliminate fruits as they form because this uselessly tires the plant, and cut wilted stems.
Callistemon needs water at the beginning to trigger root growth and settling in after transplanting.
Once it has settled in properly, callistemon can tolerate drought, but you can still go ahead and water from time to time to promote blooming.
Potted callistemon needs to be watered regularly, as soon as the surface soil is dry.
Most garden pests and diseases will find their way to your callistemon, but they’ll rarely endanger the plant gravely.
The bearing of this shrub with abundant and original blooming is magnificent. Another name for it is bottle-brush, due to the fact that the flowers look uncannily like that kitchen utensil!
Native to Asia and to South-East Australia, it is inclined towards rather warm climates when grown directly in the garden, but will adapt well to lean-ins and other greenhouses when potted or in containers.
You can trigger more blooming by often adding liquid organic fertilizer, especially as an indoor plant when the soil tends to quickly lose its nutrients.
The name itself, “Callistemon citrinus”, comes from ancient Greek, and refers to the beauty of its stamens and to the fragrant lemon-like scent of its flowers.
You must water regularly in summer but not too much, taking care to water in the evening to reduce evaporation.
