Plant my radermachera
Tropical plant, liking warm and humid environments, Radermachera sinica adapts rather well inside our houses and our apartments.
It will grow well with a temperature ideally between 21 and 24 ° C in summer and 15 to 18 ° C in winter, and it needs light.
Be careful: avoid placing it right behind a window facing south, the direct exposure could scorch it. Therefore prefer the proximity of a window facing west to bathe it in brightness.
Water my radermachera
During the growing season (spring, summer), watering must be fairly regular - about twice a week.
In the autumn, gradually space the waterings, until the winter, when the plant is being at rest. You will only have to prevent the root ball to dry completely.
Depending on the moisture of your home, a simple intake of water once or twice a month should suffice.
In case of prolonged drought, the radermacher will have a strong reaction: all the foliage collapses due to lack of water. In this case, immerse the jar in a bowl of water for a few minutes. Let it drip before replacing the saucer. Spray the foliage abundantly - and empty the saucer again.
Spray my radermachera
In dry weather - and it is also valid in our winter because apartments sometimes are too heated! - do not hesitate to spray your plant with not calcareous water.
Clean the dust on the leaves: this will show the bright green leaves, and you'll protect your radermacher from spider attacks.
On the other hand, avoid doing so in a wet atmosphere, leaving too much moisture on your radermacher for too long - this could attract cochineal or other diseases.
Prune my radermachera
You can prune lightly in the fall, to give your plant a compact and bushy shape.
Fertilize my radermachera
Beginning in May, every two to three weeks, add liquid fertilizer for green plants. You can also include in the soil mix a slow-release fertilizer in the form of small balls during repotting. Forget any input in the fall.
Repot my radermachera
Every 3 or 4 years, at the end of winter, transplant your radermachera carefully to a slightly larger pot than it's current, adding a mixture of fibrous compost and garden soil, maybe with an extra of slow fertilizer.
Propagate my radermachera
The Radermachera is multiplied by cutting in September. Take a cutting with 2 or 3 leaves. Cut the leaves in half. Dip the base of the stalk in cutting hormone powder and plant in an 8 cm pot filled with a wet mixture of peat and sand.
Cover with a perforated transparent plastic bag. Keep in heat and dim light for 3 weeks. Remove the plastic bag and water moderately, allowing the top of the mixture to dry between watering. 2 to 3 months after the start of the operation, replant the cuttings in an 8 cm pot filled with a mixture of potting soil, and grow normally.
Check on my radermachera
Keep an eye on the leaves: if they dry up abnormally, it's probably because the atmosphere is polluted.
Always place this plant in a perfectly healthy and airy room - in any case, never in a kitchen or in a room where someone smokes!
The radermacher may also be the victim of mealybugs - especially in an atmosphere that is hot and moist - revealed by a mealy white substance on the leaves. As soon as the cochineal appears, remove their shells with a rag soaked in beer, 90 ° alcohol or soapy water.
In case of large invasion, immediately wash the infected branches.
Put outside my radermachera
In summer, put your radermacher outside, in a sheltered situation.
