.. Ficus altissima Blume, the council tree, is a large spreading tree
with thick, ovate to elliptic leaves 6 inches or longer. The tree is
native from Assam to Malay and the Philippines. Podocarpus nagi (Thunb.)
Zoll. & Moritizi ex Mak, the broadleaf podocarpus, grows to 90 feet with
2-3 inch long elliptic to ovate leaves (5/8-1 inch wide) in its native
habitat in central and southwest Japan.
To determine the feasibility of using these plants in an interior
landscape, experiments were initiated at the Central Florida Research and
Education Center Apopka, FL.
Liners were placed in 8 inch pots, February 12, 1987, containing a
mixture of Florida sedge peat: builder's sand (3:1 by volume) with 7 pounds
of dolomite and 1 pound of MicroMax added per cubic yard. Plants were
grown under 47% shade (4,000-6,000 ft. candles maximum depending upon time
of year) at 50-900F. Plant height, grade (l=poor quality, 5=excellent
quality) and number of laterals were determined throughout the experiment.
Treatments are described in Table 1. Initial treatments with the high
fertilization rates caused leaf burn of podocarpus, so the remaining
fertilizer for podocarpus and ficus applications were reduced by 50%.
Ficus were placed in interior rooms 2 July 1987 with temperatures between
70-800F and light levels of 150 ft-c provided by cool white flourescent
tubes 12 hours daily. Podocarpus were placed indoors 22 Oct. 1987. Half
were placed under 100 ft-c, and half under 200 ft-c. Podocarpus fertilized
at the high level and grown under 100 ft-c dropped most of their leaves and
were discarded 17 Dec. 87. All ficus were topped at 70-cm 22 Dec. 87,
randomized and fertilized with 5, 10, 15 or 20 g 19-6-12/8-inch pot.
Within 2-3 months after initiation of the experiment, many of the
podocarpus needed to be staked, the plants receiving the higher fertilizer
levels had the weaker stems. Height (Fig. 1 & Table 1) and grade (Table 2)
of podocarpus were lowest when given the higher rates of fertilizer. Six
to 12 g of 19-6-12/8-inch pot at 3 month intervals appears to be a
satisfactory fertilizer rate for podocarpus.

Plant grade decreased as podocarpus remained in the interior except
for those plants that received the low rate of fertilizer (Table 2).
Podocarpus nagi appears to be a good candidate for indoor use if
nutritional levels are kept low.

Ficus altissima grew from about 50-cm to 100-cm from Feb. to Aug.
Fertili3z levels had no effect on height, but did influence number of
laterals (Table 3). Ficus placed in interior conditions remained
attractive from 2 Jul. 87 to 8 Mar. 88 when the experiment was terminated.
Plant grade in the interior was not affected by fertilization treatments.

Results from these test suggest both Podocarpus nagi and Ficus
altissima have good potential as interior plants. Large plantos- -Ficus
altissima have a texture comparable to Ficus lyrata and the ability to
branch more freely than Ficus elastica 'Decora'. Podocarpus nagi is a
coarser, more open, less s-tiffly pyramidal plant than Araucaria
heterophylla, the Norfolk Island pine.
