Cordylines are a genus of ornamental shrubs and trees grown primarily for their foliage. Cordyline varieties usually have a single trunk with several ascending branches, each topped with a large thick mass of long sword-like leaves, and the colours range from Red, green, purple and yellow shaded with dark pink.
Agro Climate :
Cordylines are native to Hawaii, South America, New Zealand and Australia. Although they have a tropical air, cordylines can cope with temperatures down to –5oC (20oF), so are hardy in most areas. In very cold regions it is worth trying the leaves up to the stem so that the crown is protected from the worst of the winter weather.
Any well-drained garden soil with added organic matter. Once established they need little water and will tolerate dry soils

A well-drained compost is an ideal mix, and you will occasionally over the summer period need to feed with a general base fertiliser along with keeping an eye on the watering. The report in a well-drained potting mix, add organic fertiliser or a slow-release fertiliser if this is your preference and water. Keep in a shaded well-lit position, and if a full sun plant, introduce the plant to the sun over a week or so. If planting in the ground, dig a suitable hole, add fertilizer and mix thoroughly, then plant your cordyline.
Cordyline seeds should be sown in the spring and are best started in a propagator and then moved into a warm, sunny spot once the weather warms up. In their first winter, they are best moved into a greenhouse or conservatory for some protection while they are still young.
Methods of Planting
Cordylines can be propagated from Tissue cultured plants /hardwood stem cuttings. Take sections out from healthy stems, about 10cm (4in) long. Make sure you take the sliced cuttings with a sharp knife. Lay them wound side down in free-draining compost, water and keep in bright shade.
Water the cordyline partly through rainfall or completely through hand watering. Provide additional water if, at any point, the surrounding soil feels dry to the touch. Use non-fluoridated water. Place a humidifier to provide adequate humidity.
It is worth digging in some well-rotted farmyard manure before planting. This will add lots of nutrients to the soil and help to retain moisture without making the soil waterlogged. A general liquid houseplant fertilizer at reduced strength, on the soil but never on the foliage.
Fairly fertile and well-drained soil with good aeration and water-holding capacity. A soil pH level of 6.5 is preferred. Water moderately and regularly, keeping it evenly moist. At lower temperatures, water sparingly and allow soil surface to dry slightly between watering. Bright light or nearly full sun (not direct or scorching sunshine) is best to maintain strong foliage coloration and vigorous growth. Tolerates low-light to shade, but leaf variegation can be affected and become a tad dull due to a reduction in light intensity. Constant warm conditions are beneficial.
Disease & Paste Management
Cordylines can occasionally rot at the base of their stems if overwatered or if planted in soil that remains wet. Once this happens, the cordyline topples over, and there is nothing that can be done to revive them.
Syngonium is a genus of about 36 species of flowering plants in the family Araceae, native to tropical rainforests in Central and South America. They are woody vines growing to heights of 10–20 m or more in trees.
Bright light but no direct sun. Variegated types can handle more direct sun, while deeper green varieties can handle partial shade. Prefers warm and humid conditions. Does best in temperatures between 12 – 28°C.
Rich, well-drained potting mix.
The distance of planting should be 9″ cc. Mix the following: 50 percent potting soil; 20 percent peat moss; 20 percent orchid bark with charcoal; 10 percent shredded sphagnum moss and a handful of perlite. Place this mixture in a pot, beds or garden and plant your Syngonium. Proper site preparation ensures years of growth and once established, they will not require weed control. Strong growth will Soil Ph should be around 5.6-7.0
Methods of Planting
Use an equal-parts combination of soil-based potting mixture and coarse leaf mold or peat moss. Report each Syngonium every spring, moving the plants into pots one size larger when roots have filled the current pots. These plants do not require large containers. A 13 or 15 cm pot or a 15-20 cm hanging basket should be the maximum required. After such size has been reached, top-dress plants every spring with fresh mixture.
Spray frequently to maintain high humidity. Keep soil continuously moist throughout spring and summer, and reduce watering in the winter, but don’t let it dry out. Keep the soil moist during the growing period. Allow the plant to dry out slightly between waterings in winter.
Feed regularly with liquid fertilizer throughout the growing season. During the warmer months fertilize with one half-strength fertilizer with a balanced N-P-K ratio or 5-5-5.
Tissue-cultured plants established as plugs. Since the plug, plants are usually multi-branched and in a vigorous condition, as received by the finished plant grower, production time is minimized. The potting medium should have good aeration and water-holding capacity. Syngonium will tolerate a moisture deficit in the soil but will grow more vigorously if the soil is not allowed to dry. Most growers are successfully using one of the commercially available, preformulated, lightweight peat-based potting blends. Suggested light levels for potted plant production are 1500-3000 foot-candles which can be obtained with 70 to 80 percent light reduction during Florida summers. Excellent growth can be achieved with a 3-1-2 (N-P2O5-K2O) ratio of liquid or slow-release fertilizers when applied at the rate of 2.9 pounds of actual nitrogen per 1,000 square feet per month.
Disease & Paste Management
Major pests: Leaf-eating caterpillar and white grub. Major diseases: Leaf blight and red spot. To control leaf-eating caterpillars, spray 0.2 per cent met the aqueous acid solution at fortnightly intervals. White grub can be easily controlled by the application of Aldrin @ 25 kg per hectare at the time of last ploughing during land preparation. Spray Bavistin solution @ 1 g/l at 25 days interval (2 times) to control the diseases.
