General Information

APG-III Classification:
Asparagaceae (Nolinoideae Subfamily)

[ druh-SEE-nuh mar-jin-NAY-tuh ]

USDA hardiness zones: 10B through 11

Optimal Soil pH: 6.0-6.5 [ strict to avoid chlorosis (<6.0) or iron deficiency (>6.5) ]
Optimal Temperature Range: 70-90°F
Optimal Soil Temperature: 70-80°F
Indoor Temperature Range: 70-80°F

At soil or air temperatures less than 65°F, very little growth will occur.

Minimal Safe Temperature:
"Plants will be damaged at 35°F air temperature if exposed for short periods, 1-2 days, or if exposed to 55°F for 1 week.

To simply protect the plants from cold damage, a minimum of 50°F should be held and plants should be sheltered from wind.

Temperatures below 50°F, but above freezing, have been observed to cause chilling damage when plants are exposed to wind."

Optimal Humidity Range: 60-100%
Optimal Light Level: 3250-4000 ft-candles
"Plants grown above 4000 ft-c probably will not survive well when placed indoors as plants grown at lower light levels."

Optimal Fertilizer Ratio (N:P2O5:K2O): 3:1:2 or 3:1:3
(Osmocote 19-6-12 is a good approximate source of this for a time released formulation)
Optimal Nitrogen rate at prescribe light levels & temperatures: 10g square-ft monthly

Avoid use of nutrients blends which contain excessive boron and superphosphate which contains fluoride. Fluoride (F), a non-essential plant element, can induce leaf chlorosis and other foliar abnormalities in dracaenas. It is found in most tap water, soil mix ingredients and fertilizers, especially superphosphate."

Pre-wash any perlite added to growing medium to leech the majority of the excess fluoride from it.

MOISTURE:
Rainwater or other properly filtered water (RO, Distilled, etc.) is far preferable to tap water (which contains Chlorine & Fluoride. The Chlorine will evaporate over time if the water is left to sit and or is aerated, the Fluoride however will not).
