Dieffenbachia longispatha care

Dieffenbachia longispatha grows most frequently along streams, in deposits of sediment along lakes, in standing water, but also in deep soil in the forest understory. Frequently it is found solitary or in small clusters.

 Dieffenbachia longispatha is a species of genus Dieffenbachia. This species was described by Adolf Engler & Kurt Krause in 1915.


 Dieffenbachia longispatha ranges from central Panama to northern Colombia, mostly from sea level to 180 m, but perhaps to 250 m, occurring in Tropical moist, Premontane wet, and Tropical wet forest life zones. In Panama it occurs on both coasts, but it is relatively rare on the Pacific slope. It grows most frequently along streams, in deposits of sediment along lakes, in standing water, but also in deep soil in the forest understory. Frequently it is found solitary or in small clusters.

 It is a herbaceous perennial grows 1.5-3.5 m tall, stem prostrate at base, then erect. The leaves are oblong-elliptic, 41-72 x 17-38 cm, upper surface dark green; lower surface slightly paler. The species is characterized by its usually tall and robust stem (usually 6-12 cm diam.), and by the petiole being inconspicuously sheathed and decurrent at the apex with a long subterete free portion beneath the blade, this drying characteristically olive-green or dark brown.

 This species blooms principally during the first half of the rainy season between June and August, while fruits mature throughout much of the dry season and the first half of the rainy season, especially from February to September. The berries are bright yellow to orange.


 Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.


 Dieffenbachia longispatha tolerates a wide range of light conditions. Preferred levels of 1000 to 2000 foot candles. They will grow in heavy shade and can be used in dark areas of the home, but growth will be slowed. Best growth is achieved in bright indirect light.

 Insufficient light can cause the lower leaves fall off and plant becomes leggy. Leaf yellowing or discoloration caused by plant being in full sunlight.

 Rotate the plant regularly to provide adequate light to all sides of the plant and prevent it from reaching toward the light on one side.

 Best growth occurs between 65° and 75°F. The temperature should not drop below 50°F. The lower leaf drop because of sudden changes in temperature, or the plant is in a drafty location.


 A relatively moist atmosphere results in vigorous growth, because its large leaves may dry up in a hot room. Maintain humidity by grouping plants or with a pebble tray.

 Low humidity in the room can cause the leaves dry up. Position the plant away from radiators, group plants, use pebble trays.

Substrate and growing media:

 Dieffenbachia longispatha needs a loose, fertile, high organic medium. Many different mixes can be used. The plants can be grown in pure peat; peat and perlite (1:1), soil and peat (1:1); or soil, peat and perlite/vermiculite (1:1:1). The growing medium should have good water-holding capacity and be well drained.


 For smaller desktop plants, repotting once every 12-18 months with a potting vessel 1”- 2” larger in diameter to allow for growth. For larger floor plants, repotting every 18-24 months with a potting vessel 2”- 4” larger in diameter to allow for growth.

 Don’t choose a pot much larger than the previous as this could drown the plant's roots. If you prefer to maintain the current size of your plant, repot into the same vessel, providing new soil and trimming away some roots and foliage. Spring or summer is the ideal time to repot as the plant is at its strongest.


 Maintain moderately moist soil. Watering is an important part of growing this plant. Water thoroughly and then not again until the surface of the potting medium is dry to the touch. Plants can be rooted and grown in water. Plants grown in soil should not be water logged; the plant will not tolerate constant overwatering. Overwatering cause yellowing and dropping off of lower leaves, plant rots off at the base.


 The plant given a minimal amount of nutrients will grow slowly and retain a desired shape. If the plants are growing in limited light, they require less frequent fertilization. As a general guide, you can use a complete fertilizer such as 20-20-20 and feed every 4-6 weeks only during the active growing season.

 Brown leaf edges and/or leaf tips, tip burn because of too much fertilizer or too dry for short periods. If there are excessive fertilizer salts in the soil, these salts will be in solution in this water droplet. When the droplets evaporate, the salts remain on the tip of the leaf and cause tip burn.

Pests and diseases:

 Bacterial Rot/ Blight - a bacterial pathogen that causes soft rot. Ants can cause considerable damage because they carry certain aphids, which in turn secrete a honeydew. The ants gather and feed on this honeydew. Fungus may develop.

 Mealybugs: The nymphs of this pest feed on the sap of the plant by piercing the outer layer of plant tissue and secrete the honeydew that is attractive to ants. Mealybugs can be controlled by wiping the area with a cotton ball dipped in rubbing alcohol.


 New plants can be made from stem cuttings. Use tip cuttings from the terminal portion of the plant or from small shoots that develop from lateral buds. Be sure to avoid contact of the plant juice with skin.

 Stems that have become bare from dropped leaves can be cut into 2” pieces (with at least one lateral bud). Dry the cuttings for a day, then stick them in a rooting medium such as peat, sand, perlite or vermiculite. Stem cuttings establish roots faster in sphagnum moss than in sand, and cuttings from the top of the plant root faster than sections taken from the base of the stem.

 Larger stems initiate roots faster than smaller stems, apparently because the larger stems contain more stored food. Air layering can be used when the plant becomes top-heavy or lanky with naked stems.
