fiddle leaf fig is a tropical plant that fully loves light. It does best in bright, not direct Sun, quite a lot needed for healthy growth, but without risk to burn the leaves. Can you manage to reach the right lighting?
Honestly that ranks between the main steps, that you can take for such green friend.
How Much Light Does a Fiddle Leaf Fig Need?
Windows facing east show up as a good option, because they give sweet light in the morning. That helpful Sun early helps the fiddle leaf fig reach its ideal state. Rooms facing north, on the other hand?
They simply do not work. Such plants need light, that passes through a filter, at least during six hours a day, and north rooms usually fail to provide that.
South, west and east spots all work well. If you lay the plant beside one of those windows, it will receive steady light along the Sun path of the day. When you find the ideal place, avoid the temptation to move it often.
Plants of taht species truly dislike constant motion.
Here it gets hard. Direct sunshine can hurt the leaves, especially when harsh afternoon Sun hits a west window. If you do not mind, brown marks will appear on the leaves.
The good news is, that fiddle leaf fig plants handle direct Sun, if you get them used to it slowly. The way is to slowly grow there exposure to full light during one or two weeks. Skip past that change phase and lay them under direct Sun too sharply are typical beginner mistakes, that happen often.
If light periods turn short, the fiddle leaf fig gets thin and nearly strained instead of dense and strong. It even will start to lose leaves as warning. When the plant leans or reaches toward a window, that signals, that you must move it to a brighter place right away.
The perfect situation is, when the leaves almost touch the glass.
A small amount of direct sunshine daily works well. Problems come from strong afternoon Sun. Do you provide filtered light during the whole day?
That is the winning recipe. A southeast window or even LED grow lights give the wanted strength. Watch for brown spots around the edges, that points, that the light weighs too much.
Plants adapt to darker settings, but their growth slows until it stops. Too little light can cause brown spots low on the leaves. If you see no new growth during several months, probably the plant lacks enough light.
Outside in warm areas, fiddle leaf fig plants grow under full Sun. There are even sixty foot examples in full Sun at the San Diego Zoo. Mostly, the more sunshine those plants receive, the more wellthey grow.
After adjusting they last six to eight hours of direct Sun daily. More light means a healthier plant.
