Position/Lighting
As an indoor plant, Ficus maclellandii “Alii” does well in a partially sunny to semi-shady position, receiving morning, evening, or winter sun.
If acclimated, it can tolerate full summer sun, but in this case the pot or container must be large enough to prevent the soil from drying out within a few hours. On hot summer days, the plant’s water requirements are much higher than in winter.
During the warm summer months, the fig tree can be placed outside in the garden or on a balcony. Either in partial but not deep shade, or gradually accustomed to direct sunlight that is no longer filtered through window glass.
Soil
Standard potting mixes for houseplants, container plants, herbs or vegetables can be used.
The Alii fig shown here is growing in a mix of peat-free potting soil, bird sand and lava gravel.
Lava gravel is tough and porous and can hold up to 30% of its own weight in water. I use it as a single potting medium for many of my houseplants. However, I haven’t tested whether Ficus Alii will tolerate it on its own.
Watering
The pot ball should be kept slightly moist at all times. It may dry out a little between waterings but should not be allowed to dry out completely. Even if the surface appears dry, there may still be some moisture in the bottom of the pot – this is where most of the roots are located.
Waterlogging is not tolerated. However, if water remains in the saucer or planter for a few hours in the summer, this doesn’t count as waterlogging.
Fertilising
Ficus maclellandii “Alii” can grow to be several metres tall, even as an indoor plant, so I fertilise sparingly.
For the first year after purchase or repotting, fertiliser is not necessary as most potting mixes contain pre-added nutrients.
After that you can use slow-release fertilisers such as sticks, granules or pellets in spring and summer.
Liquid fertiliser can be added to the water once a month from April to September, or weekly at a low concentration.
Temperature
The Alii fig will tolerate room temperature all year round, but can be overwintered in a cooler environment around 59 °F (15 °C). Temperatures should not drop below 50 °F (10 °C) for long periods.
Humidity
Unless the fig tree is placed next to a heater in winter, it will do well with humidity between 40 % and 60 %.
Regular misting won’t raise the humidity much, but will help to remove dust from the leaves. However, a monthly shower is more effective against dust.
