Do you looking for information about techniques of cultivation the rose. Rose seeds can be propagated by stem cuttings, grafts, and the most popular is the grafting. Cultivation by stem cuttings used for rootstock and hedge roses are commonly used as rootstock, because this kind of strong, fast growing, disease resistant and easily propagated by cuttings.
Most employers cut flowers rose in Indonesia is still importing seeds from Holland. Seedlings are shipped usually a result of grafting plants that have been aged three months and a half year-old seedlings. When using a three-month-old seedlings of new plants the results obtained after 6 months of planting. These seeds are imported form other than seeds scraped without media (stump), also can be a seed in artificial media, such as roockwool. Half-year-old seedlings usually a stump, the seedlings without roots and without leaves. These seeds are the result may be taken four months after planting by providing a new branch about two or three main branches.
Land preparation and planting.
Sand, manure and garden soil needed for growing media in the ratio 1:2:1. Manure is given at the beginning of planting. The basis of super phosphate fertilizer as much as 0:25 kg/m2 be 1-2 weeks before planting. If soil is too acidic agricultural lime can be added as much as 2.5 kg/10 m2 and when the soil is too alkaline can be added to the sulfur ¼ kg/10 m2. Manure is given as much as 75 tons / ha. Additional fertilizer NPK 50 kg / ha / bl. Provision of micro elements Fe, Mg and S can be supplied through spray once a month. Sterilization can be done using chemicals or vapam basamid with the recommended dosage.
Preparation begins with making planting holes about 15 cm in diameter with a depth of 30 cm. Spacing depends on variety. Spacing Hybrid tea and floribunda types of 100 cm x 60 cm, was kind Polyantha 40 cm x 60 cm. Several new varieties of cut roses grown at a distance 31 cm x 31 cm or 38 cm, or 20 cm x 40 cm depending on the type of roses are grown.
Installation of the protective net 50% of shading done to avoid the high transpiration of young shoots. This shield can be opened after a four-week-old plants. For the vines can be made pergola beams.
Before planting, seeds were sterilized before the fungicide solution, such as Benlate (0.5 g / l) for a minute or two. Planting is done by placing the seeds in the center of the hole and tried to be the roots spread in all directions and nothing is broken or bent. Once planting is completed in the form of sprinkler irrigation or drip can be retrofitted and newly planted seedlings are watered until moist enough.
Maintenance of Roses
Formation of the Young Plant. Formation of roses done by cutting / pinching. It is intended to maintain the plant in order to stay young, so it is always producing new shoots are prolific flowering. Of new shoots which emerged five weeks after planting flowers that will emerge will be small and should be cut . Soft pinch performed on young shoots, aiming to maximize vegetative growth. Will new stem with reddish color will grow out of seeds or branches of the branch shoots first. These shoots are allowed to grow to adulthood and long after the colorful flowers will then be immediately removed (pinching is done on old shoots is known as a hard pinch).
Bending plant performed when the seed is old branch. Place the bending buds / stem to the bending of about 5-10 cm from the base of the stem. To help back up the shoots did not shoot the parts can be attached with a piece of bamboo that is attached to the ground. That the bending of the shoots are sometimes small grow new shoots will come out the interest rate should be discarded and leaves cut as many as two true leaves (five leaves) so that plants have many leaves.
The new shoots that sprout production is going up after a few weeks to do the bending. At the time of harvest, shoots are cut, leaving 3-4t true leaves. Of shoots that had been harvested after about 10 days in general would appear two or three new buds and will bloom after about 6-7 weeks. Production of shoots was then harvested by leaving two true leaves.
Trimming. Purpose of trimming to maintain shape of the plant in order to obtain a solid rod, encourage flowering, plant regeneration, producing new shoots of high-productivity, and maintain the plant to stay healthy and live longer.
Pruning is done is trimming mild (30%) by cutting the tops of the little rose bush, so as to produce many flowers but small. Pruning is (50%) performed by pruning the branches or shoots, but not too long. Usually done on the types of Floribunda and Polyantha. While heavy pruning done on the old stems and plants that have been severely affected by diseases carried by pruning entire branches to a height of 60 cm or leave the two-three eyes of each rod.
Pruning for crop establishment can be done also with a set way of cutting the time of harvest. "Trimming the usual" is done by leaving one or two leaves of five (ie leaf that has five individual leaf blade) of branching, known as the normal cut. "Cutting in" is done by cutting the stem below the branch known as the under cut. The harvesting is done in the second year in order for low-branching plants grow back. "Trimming the joints" is done by cutting the flower stalks just above the branching to be harvested, known as knuckle cut. How this is done when the cultivation of roses is entering the third year that high-return crops.
The best pruning time is just after the rainy season ends, so when it is generally fertile plants in the state with the formation of irregular branches and twigs. Prune once a year.
Fertilization. Fertilizer for roses hanging from the analysis of soil to be planted, so that every garden / growers have rules different fertilization. According to the research needs to be cultivated roses as much as 5 grams per plant at the age of one-two weeks after planting. Fertilization can then be given once a month depending on plant growth.
That's a technique we can use to cultivate rose plant. There are so many techniques we can use, just select the way that you think most convenient and most suitable to your environment.
