What really needs to be said about the Ficus Lyrata? If you want to be cool you have to have this plant. Give it lots of light and very little water then just be cool. Bush forms are grown in 10 in. up to 17 in. pots with heights from 34 inches to 10 feet tall. The bush has foliage from top to bottom with multiple stem for fullness. The standard form is grown in 14 to 28 inch pots with heights from 5 feet to 14 feet tall. You might know it by its famous stage name Fiddle leaf fig.
The meters below indicate a range of light and tolerance to drought. The ranges are indicated by the little light bulbs and the small water drops.
Mites should be primarily controlled with predator mites. Neoseiulus californicus,(Spical, Spical Plus, Californiline) and Phytoseiulus persimilis,(Spidex, Bio Persimilis, Phytoline) are two excellent choices for spider mite control. If a mite infestation is exceptionally bad, prior to the release of predator mites, spray the plant with water or horticultural oil. Both will provide some knockdown control of spider mites and will not leave a toxic residue that may effect predator mites. If the population of spider mites is red in color, (as opposed to pale yellow with 2 dark black spots) then californicus mites are the only option. Even these predators do not feed heavily on the red spider mite. In this case spraying is the best option. Use a miticide that works well with californicus predator mites (Sultan, Floramite SC, Shuttle O).
Mealybugs can be removed with a systemic insecticide drench and hand cleaning. If pesticides are not an option, try horticultural oil directly sprayed onto the insects. A second and third treatment, if using oils, will be necessary. Space out the sprays at 3 week intervals to break up the mealybug life cycle. Mealybugs like to hide against the stem, just below the newest one or two leaves, inside the dried remains of the leaf sheath (Link to pictures below).
Aphids can be controlled in the same way as mealybugs.
Thrips can cause red lines and spots on the newest emerging leaf. Check the link below for pictures of thrip damage. Thrips are difficult to find. They most likely will be inside the leaf sheath of the newest leaf. Let the lyrata dry to prevent the production of a new leaf and spray horticultural oil on the newest foliage. Repeat treatments of the oil spray on a weekly basis for 3 weeks then observe.
Lyrata can be kept very dry without negative consequences. With a surplus of water the lyrata will try to grow, too rapidly given certain conditions. Since many pests like the newest soft foliage reducing the number of new soft leaves can be advantageous.
Large dry brown dead areas of a leaf indicate low light damage. Parts of a lyrata leaf may die while the rest is nice. This happens when a higher leaf is shading a lower leaf. The portion of the lower leaf being shaded may die. It is also common to see the foliage away from the light source look noticeable worse than those facing the light source. When this is happening to upper foliage, that is not being shaded, the entire area is too dark to sustain the Ficus lyrata. Move it to a brighter area.
