The choice of varieties of roses
The autumn season is a crucial moment for the cultivation of roses; the health and beauty of these plants depend on the transactions carried out in this period.
The best time for planting roses coincides with that of the absence of leaves unless using plants that are grown in pots. For best results, the planting of the roses is done in late winter, when the temperatures are increaseing thus encouraging development of leaves and roots.
Roses are very long-living plants that can live for decades, therefore their cultivation can be very rewarding.
Depending on where you would like plant them, the choice of the most suitable variety of rose must be well thought over. In order to have a good choice and lots of useful information and suggestions you should contact specialized nurseries.
Rules to follow
When you have decided where to plant your roses, you must make sure that during the previous 2-3 years other roses have not been coltivated in the same area . If you intend to plant them in the same area, replace at least 30 cm of soil or leave the land aside to rest for at least one year.
Use mature manure as fertilizer; it is the ideal fertilizer because it brings both humus and good fertilizer soil. Alternatively you can use other organic materials (dry leaves, peat, ...) added to the delayed-release fertilizers
Shorten the branches up to the woody part and eliminate those that are too thin or malformed.
Before planting, do not expose to air the roots of fresh roses and remove broken or damaged roots. The most common cause of failure in growing new roses is the wrong planting procedure. Also keep in mind that roses do not tolerate water stagnation. If the soil does not drain well you must create an artificial drainage by using gravel.
Dig a hole big enough to accommodate the well-opened root system and cover with soil to the right depth so that the rose is at the right level with the ground.
Press the earth filling. Water repeatedly in order to eliminate the air pockets that may subsequently cause the lowering of the rosebush.
Bare root roses and roses in pots
The bare root roses are planted from November to late March and have a lower cost than the roses in pots. The roses in pots can be planted during any of the 12 months of the year, and you can buy very large roses with an immediate scenic effect.
Pruning perpetual roses
Pruning is the most delicate phase of the cultivation of roses. It should be performed mainly before the vegetative growth, ie at the end of January or February. Pruning:
- Contains the size of the plant;
- Stimulates new basal growth ;
- Removes dead and malformed branches;
- Channels the nourishment to fewer stalks for less flowers, but bigger and nicer ones.
The water requirement of roses
Usually for a medium size rose shrub you will need from 12 to 15 liters of water, twice a week. As the temperatures increse, you will need to reduce the interval between watering.
For the cultivation of modern roses that bloom a lot in May June and July we recommend a second dose of slow release complex fertilizer (about a handful) around July or August.
