How to Grow Tropical Rose

Terms of Growth

1. Climate.

Wind does not affect growth in the rose. Rainfall for the growth of a rose is a good 1500-3000 mm / year. Requires 5-6 hours sun per day. In the area enough sun, roses will be diligent and faster flowering and trunked solid. Morning sunlight is better than in the afternoon sun, which caused the drying plant.

Power plant roses have adapted to the environment are widely grown, it can be planted in a cold regions / sub-tropical regions and in the hot tropics. Cool air temperature 18-26 degrees C and humidity 70-80%.

2. Embed media

Planting is done directly on the land permanently in the garden or in the pot. Plant roses in suitable sandy loam (clayey matrix 20-30%), fertile, friable, many organic materials and good drainage.

Degree of soil acidity that is ideal PH = 5,5-7,0. In the acid soil (pH 5.0) add dolomite lime, Calcit or Zeagro dose of 4-5 tons / hectare.

Gift aims to chalk raise soil pH, add the elements Ca and Mg, to improve the life of microorganisms, improving the root of the pimple-pimples, reduce the virulence Fe, Mn, and Al, and increase the availability of P and Mo. Land-permeable pore is needed by the root roses.

3.Altitude Places

Roses grow well in:

- Altitude of 560-800 m dpl, minimum air temperature 16-18 degrees C and a maximum of 28-30 degrees C.

- Altitude of 1100 m dpl, minimum air temperature 14-16 degrees C, a maximum of 24-27 degrees C.

- Altitude of 1400 m dpl, minimum air temperature 13,7-15,6 degrees C and maximum 19,5-22,6 degrees C.

In the tropics such as South East Asia, the plant can grow roses and productive flowering in low to high (mountain) average of 1500 m msl

Time of planting roses are at the beginning of the rainy season (when the boiler is adequate can be done throughout the season / year. The roses are planted seedlings (without soil), and seeds derived from the polybag.

How to seed planting roses :

a) Unloading seedlings from the garden of roses

b) Cut the stem and some branches, 20-25 cm left for Habitus plants that become short.

c) Cut some radical barbershop scissors with sharp and sterile.

d) Put rose seeds in water solution substance Organizer grow (ZPT) as Dekamon 1-2 cc / liter for 15-30 minutes.

e) The seeds of roses in the middle of the planting hole and the root is set to spread all directions. Fill it to limit the land base of the stem neck.

f) Steem soil around the plant stem roses slowly so that roots can direct contact with the ground water.

g) Water land around the plant until the roots are wet.

h) Place the auspices of plaited bamboo / other materials for the plant to cover rose from afternoon sun.

Plant Maintenance weeding

Weeding activity usually coincides with the fertilization in order to save costs and labor. Grass that grows wild in the ditch / trench so that the nest does not become pests and diseases.

Weeding once a month (depending on the growth of weeds), pull out the wild grass (weeds) are careful not to damage the root of the plant or equipment to clean with hoe.

Fertilization

The type and dose (dosage) of fertilizer is recommended to plant roses is fertilizer NPK (5-10-5) as much as 5 grams / plant. When shoot growth slow in comparison fostered NPK 10:10:5, when their stems weak comparison 5:15:5 NPK fertilizer.

The type and dose of fertilizer is a mixture of fertilizer that consists of: 90-135 kg N plus 400 kg P2O5 plus 120 kg K2O/ha/year or equal to 200 - 300 kg plus 840 kg Urea TSP plus 250 kg KCl / ha / year. Based on the results of research Horticulture Research Center (Balitro), rose plants need fertilizer NPK fostered 5 grams / tree planting or at the time of 7-15 days after planting.

Next fertilization continuously once every 3-4 months, depending on the growth of plants. Dose and type of fertilizer that is recommended is a mixture of Nitrogen fertilizer N plus 600 kg 1000 kg P2O5 Phosphate added 400 kg of potassium K2O/ha/year urea, equivalent to ± 1350 kg 2100 kg TSP plus KCl plus 800 kg / ha / year. Each time fertilization given 1 / 4 - 1 / 3 dose of fertilizer added 337,5-450 kg Urea TSP plus 525-700 kg 100-133 kg KCl per hectare. The provision of fertilizer should be at the time before flowering, and flowering, and flower bud after fading.

Irrigation and sprinkling

a) In the initial phase of growth (around age 1-2 months after planting), performed continuously 1-2 times each day. Next watering gradually reduced depending on the circumstances or types of weather and soil (media).

b) Time of delivery of water at both the morning and afternoon, when air temperature and water evaporation from the soil is not too high.
