Plant my alula
Alula likes warm and rather dry atmospheres: it adapts rather well inside our houses and our apartments. It needs light but no direct sun.
Plant it in a mixture of potting soil, pozzolana and sand: it is a plant of seaside cliffs.
Regarding the size of the pot, plan large enough and heavy.
Avoid tanks with water reserve: the roots can not stand to constantly be in the water.
Water my alula
As soon as the soil becomes dry on one centimeter, water so as to moisten all of it. During the growth period (spring, summer), watering should be regular - once or twice a week - but measured in order not to asphyxiate the roots of plants. In the fall, space the waterings gently, until winter when a simple influx of water once a month should suffice.
Fertilize my alula
In summer, add liquid fertilizer for green plants every 2 weeks. You can also add slow release fertilizer pellets to the soil mix when planting or repotting. Stop all fertilizer treatments at the end of summer.
Repot my alula
At the end of the winter every 3 or 4 years, repot your Alula!
You can also repot before, especially if the pot falls and tilts easily: this is the sign that your ficus is too cramped!
Choose a pot size barely larger than the old one, composed of terracotta, with a drilled bottom.
Sprinkle the original pot, add small stones or clay balls for drainage into the new pot, and add potting soil mixed with some garden soil. Fill until it reaches one third of the pot.
Unpot, unclamp the roots, position the mound on the potting soil, and fill. Tamp rather strongly, and water!
Check on my alula
The most asked question about this plant is: "but why are the leaves turning yellow?".
Apart from poor planting or unsuitable conditions, the most common cause is the presence of mites. You may not see them, but their bites quickly exhaust the leaves.
The solution is very simple, clean them regularly with clear water.
Put outside my alula
If you have the opportunity, place your Brighamia outside in the summer, in the shade.
Shelter my alula
Put your Brighamia indoors at a temperature of 18-22 ° C, not lower than 15 ° C for the whole winter.
Place it near a window, in bright light, without direct sun, sheltered from cold drafts.
