The common practice of growing roses in containers and the reasons backgrounding it have been quite extensive in recent years. Not long ago this flowering plant was grown in containers almost used as a last resort. This is due to the fact that the gardener run out of growing space or was limited to a balcony or patio. Roses which were considered appropriate were then limited to standard miniatures, tree roses, and small floribundas. Nurseries have provider containerized roses for quite some time yet they were commonly removed from the container and then planted in the ground immediately.
Why Should Roses be Planted in Containers?
The lack of space still remains a strong reason, for sure, but now the kinds of roses which are grown in containers for the long term comprise of larger floribundas, grandifloras, and hybrid teas, and even some of the more modern shrub roses. This particular trend has been supported and helped by the popularity of affordable, lightweight, and large containers and the improvements in plating schemes.Current developments in the field of horticultural therapy have indicated how most gardeners that find it physically hard to work at ground level can go on with the pursue of their very hobby with containerized roses, since they can be easily located at desk height.
The other important reason for the practice of growing roses in containers, which is being more popular every year, is to make it simpler and easier for the designer or gardeners to evaluate the suitability of a new rose in his particular landscape. The compatibility of the color, form, size, and all-round quality with the current plantings can be simply tried out by placing the containerized plan in its proposed area for one year or even longer prior to installing it in the ground level.
Rather than purchasing containerized roses, a lot of gardeners fancy the idea of buying bare-foot roses and then plant them in containers themselves, using their preferred brand of fine quality growing medium. Afterwards, they carefully nurse the new roses along, which provides the proper amounts of nutrients and water, till the planting time comes. This particular approach includes more work yet offers the best opportunity of developing healthy roots as well as top growth. It is also essential to take into account the container to use.
What Kind of Container is best?
Most types of containers which can include pots,troughs, tubs, and hanging baskets, will work well for rose growing although most experienced gardeners have their own preferences. The most important requirements are that the chosen containers must be quite big to allow for proper development of roots and it must be able to provide sufficient drainage. In addition it should have a wide base to resist being blown over by strong wind! Pots which are made of glazed ceramic, terra cotta, wood, plastic, or even biodegradable fiber are the ones that most gardeners use with the ubiquitous black plastic pots leading the way. Make sure that you do not use a saucer under the pot since it would be the invitation to root rot!
The size needed is highly dependent on the anticipated mature size of the rose, for sure, and it will be better to err on the generous facet. This will also assure that the pot will retain enough soil in order to avoid drying out too quickly. In order to accommodate a large floribunda, hybrid tea, shrub roses, or grandiflora, it is useful to have a 15-gallon container. One of smaller floribundas will be happy in a ten-gallon container, while most miniature of roses will fit well in the four or five-gallon size. If you want to use the container temporarily, such as experimenting a new kind of rose in the landscape, the first group can be well grown for one year or two in a ten-gallon container.
Which Planting Medium Should be Used?
This is just another area in which personal judgment is imperious. Some rose gardeners insist on using a sterile soilless containing medium, with up to half perlite added in order to lighten the mix and then provide faster drainage. The others report success when they use a made-up mix of, for instance, 30% perlite, 30% screened compost, and 40% top soil. To help the root development, superphosphate has to be added accordingly to the mixture, presumably about ¼ cup for large containers, one tablespoon for smaller ones.
Also, many rosarians add a slow-release fertilizer. For more elaborate information on the types of growing medium, which reflects local availability, it is suggested to obtain advice from your local Country Extension Office, or you can contact a consulting rosarian nearby.
Do Containerized Roses Require Special Maintenance and Treatment?
The cultural practice for roses which are grown in containers is so different in many ways. One of the obvious differences is the frequency of watering. Since it is important to provide fast drainage the soil can readily dry out very rapidly, so that it is important to have daily watering in hot weather; in fact smaller containers may require watering twice per day during hot weather. As a result, this will mean that fertilizer which is applied to the growing medium will leach out quickly, so more frequent fertilizing is important to achieve the best performance. It is highly advisable to change the soil every 3 years or so since it is likely that the soil indicates a buildup of soluble salts which are left by the fertilizer. Simultaneously the roots should be trimmed back and inspected if the rose is becoming root-bound.
There are in fact many advantages that are enjoyed by the gardener that uses containers. For instance, the containers can be simply moved around in order to find out which exposure to sun and shade best suits the rose. The considerations pertinent to freezing weather can be readily addressed by moving the container into shaded area. Treatment for disease or pests is commonly simpler since the rose can be easily isolated from the rest of the ground for the needed TLC.
