The harvested flowers should be put in warm water and kept in 4-5 degrees of temperature. If the roses must be kept for around two weeks, they can be kept in -1 to 1 degrees, but these roses shouldn’t be put in water, instead they should be kept in air and moisture proof boxes. When retrieving the roses from storage, stems should be cut a bit and they should be put in hot water, around 27 to 30 degrees.
The roses usually need 3 months from planting to harvest. It’s important to plan your flowering times according to market conditions in order to periodically harvest. For this, in addition to planting, deadheading and other factors should be considered.
While this usually is 5-6 weeks in spring and summer, the duration for winter is up to 8 weeks. Also, the soft-deadheaded plants grow 3-7 days after the hard-deadheaded ones.The temperature in the greenhouse should be considered. Another factor is the size of the stems. The longer stemmed roses need more time to mature. In addition to this, altering the night temperature by 4-5 degrees ( no more than 1 degrees each night ) can hasten or slow the process.
This situation occurs when the rose stem remains vegetative and grows leaves instead of flowers. More light intensity helps with this problem. When temperature and light intensity are increased, this problem diminishes, down to 15%. Otherwise it is up to 40%. [click to continue…]
Deadheading the shoots and buds: Roses in general, tend to grow one or two thick branches and many thin ones. For quality rose cultivation, deadheading of roses can be used to get rid of the thin branches, leaving the desired thick branches to grow even more. The new roses should be examined regularly and as soon as the new buds are 2.5 to 3 centimeters long, they should be cut from the top to stop their growth. [click to continue…]
There are four reasons for trimming your roses:
1 – Rejuvenation
2 – Efficiency Enhancement
3 – Quality Enhancement
4 – Forming
Each year regardless of how well taken care of, in time, it’s known that roses will shorten, and the development of the branches will stop, and become dry. In this case, roses should be cut just above the grafting point to achieve [click to continue…]
The period between November and March is the best for planting the roses. But they could be planted between 15th of October and end of April. Winter isn’t usually suitable for planting because of the hardness of the soil. If planting is done in late April, great care must be taken with watering. [click to continue…]
It’s important to be careful with watering of roses, as soon as they are planted. While the timing and amount of watering depends on factors such as the environment, the type of soil, the state of the plant; roses need more water in summer and while new shoots are growing. And the watering needs are low after trimming, collecting flowers and in winter.
It can be said that a decare of greenhouse needs 2000-2500 tonnes of water each year.
Depending on the temperature inside the greenhouse, the moisture should be kept in line for the best results. For example, if the temperature is 24 degrees, %60 humidity is suitable. While too much moisture causes more illness in the greenhouse, too little of it can also be detrimental for the growth. The plant loses too much water, the growth stops and the shoots become shorter.

In order to make the roses grow fast and take root easily, the soil must be prepared very well. If the soil has never been
worked on before, it must be processed deeply.
If the soil is sandy, heavy fertilizers ( composite ones, such as cattle manure ) work best. If the soil is rich in clay and/or limestone, the evergreen plant remains, or animal manure work best. [click to continue…]
The roses prefer fresh soil rich in clay and organic nutrients. This is the kind of soil which sticks to the foot when
it’s wet, but otherwise dries easily and when it isn’t too dry or wet, easy to work on. But also, the roses can grow in
any kind of garden soil. They only don’t grow in soil extremely rich in clay, sand or limestone.
According to various studies, the necessities of roses are these: [click to continue…]
