Kanjiro Camellia

Camellias such as Camellia Kanjiro Shrubs are one of the slowest growing and yet one of the most desirable ornamental’s available today. In order for camellias to give their maximum performance, certain fertilization requirements must be met. Despite their slow growth patterns, camellias are considered to be heavy feeders. In recent years, a misconception has emerged that older camellias do not need to be fertilized. The premise is based on the fact that these older and well established camellias can derive all their nutrients from their soil. Although many well established camellias perform wonderfully without being fertilized, they will do even better with a regular fertilization program.

When looking at most fertilizers, they are described by three numbers on the bag. An example would be 10-10-10 or 12-4-8. The first of these three numbers refers to Nitrogen, which is the primary element necessary for good, balanced growth within the Camellia Kanjiro. Plants that are deficient in Nitrogen are usually not growing vigorously, and sometimes exhibit pale colored foliage. Not all Nitrogen deficiencies result in stunted growth. Sometimes, the growth is taller and longer with less than desirable branching when Nitrogen is deficient. The second number in the fertilizer equation is representative of Phosphorus. A deficiency of Phosphorus may affect the energy transfer in the plant, and result in stunted growth as well. Also, plants with insufficient amounts of Phosphorus may have poorer root systems. Potassium is the element represented by the third number on the fertilizer bag. Plants that are deficient in Potassium, are usually growing more slowly than normal, have fewer flowers and seed, and are more susceptible to disease than plants with adequate levels of Potassium. Although the three elements just mentioned are the major elements necessary for good plant performance, there some minor elements that are just as important in consideration of camellia nutrition.

Minor elements that are not included in the three numbers listing on the front of fertilizer bags are very important considerations when choosing your camellia fertilizer. Elements such as Magnesium, Sulfur, Calcium, Iron, Manganese, Copper, Zinc, Boron, and Molybdenum play very important roles in providing camellias will adequate nutrition. Many times, less expensive fertilizers are sold that contain only the major elements needed, but not the minor elements. Always be sure to look on the fertilizer label on the back of the bag to see exactly what is included in the fertilizer.

In choosing the basic type of fertilizer for your Camellia Kanjiro, it is important to determine what you need your camellias to do. If your plants are well established, and you are not concerned about more growth, choose a fertilizer that has a smaller first number, and a larger second and third number. For example, a 4-8-8 fertilizer with minor elements included would be a good choice for well established camellias. If your camellias are younger plants, and you want them to concentrate their energies on growing for a few years, you may wish to choose a fertilizer that has a higher first number such as 12-4-8 or 10-10-10. Be sure that these fertilizers have minor elements as well. No matter what fertilizer you choose, “Always Read the Label”. Do not apply more fertilizer than is recommended on the label. Organic fertilizers such as Dehydrated Cow Manure or Espoma tree tone may provide an excellent source of slow release nutrients in addition to your primary fertilizer.

In the southeastern United States, three fertilizer applications per year are usually adequate to supply your camellias’ nutritional needs. Generally, an application sometime during the first part of March, followed by a second application during the first part of May, and a final third application during the first part of July should be sufficient for you camellia fertilization needs. Always consult your Extension Service and your local camellia experts as to specific recommendations of fertilizers for your area. If you do not have acid soil, soil tests may be necessary followed by ph adjustments. Camellias like Camellia Kanjiro generally prefer acid soils with ph readings from 5.5 to 6.8. If the ph of your soil is not correct, it may affect the ability of your camellias to absorb the fertilizer that is applied. It would not be a bad idea to have a soil sample checked with your local Extension Service before applying fertilizer. If you need to add some acid to the soil we recommend Espoma soil acidifier.

When you have selected your fertilizer and are ready to apply it, be sure to rake your mulch back to the drip line of each plant. Apply the fertilizer according to the label directions immediately on top of the soil, and be sure to water the plant thoroughly after the application. You can then rake the mulch back around the base of the Camellia Kanjiro. Although it is tempting to spend less time by not raking the mulch back during fertilization, the results will be less than desirable, if the fertilizer is applied on top of the mulch.

Proper fertilization of your Camellia Kanjiro will lead to healthier and more disease resistant plants, as well as provide you with many more enjoyable blooms. Always, read the label on your fertilizer bag, and follow the instructions.

We highly recommend that you mulch your Camellia Kanjiro with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do, but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away that will compete with your new investment for water and nutrients. A 2 to 3-inch layer of mulch is sufficient, but remember to take care not to cover any part of the stem of the plant with mulch. It's better to leave a one-inch gap of space between the mulch and the stem or trunk of the plant.

In general gardening terms, pruning is probably the most misunderstood gardening chore, and certainly, the chore that is most likely neglected. When we specifically look at pruning with regards to camellias, this misunderstanding and negligence can be magnified.

Pruning has been described as a “combination of art and science.” Pruning a specific plant to look a specific way, involves art in creating a unique definition for a specific plant, and it involves science in understanding the physical growing habits of the plant to be pruned.

The most important reason for pruning camellias is to improve the overall health of the plant. Many times, camellias such as Camellia Kanjiro that have not been pruned in a few years will develop dead or degenerative twigs. Removing the dead and dying limbs will minimize the possibility of diseases such as “dieback” and will also allow the plant to re-concentrate its energies.

In many instances, camellias that have been neglected for a number of years will become infested with insects such as scale. Severely pruning such infested camellias will not only re-invigorate the plant, but will also reduce insect problems and minimize corrective treatments necessary to eliminate such problems.

Another reason for pruning camellias is to re-define the plant’s definition within the landscape. Many times, a plant may outgrow its intended size in the landscape, and must be pruned to re-define its purpose. Pruning should always be associated with re-invigorating a plant by allowing it to focus its energies on producing more vigorous branches, foliage, and flowers.

Specific plant objectives require specific pruning techniques. If a Camellia Kanjiro is being trained as an hedge, it would need to be pruned differently than if it were being grown as a tree form. Screenings and hedges of camellias would need to be pruned for their specific purpose within the landscape.

It is also important to understand the specific growing characteristic of a certain camellia when pruning that particular plant. For example, certain camellia varieties such as ‘Seafoam’ are extremely vigorous growers, and should not be pruned to maintain the plant as small shrub.

When pruning established camellias where no labeling is present on a variety to identify it, you need to look at the general growth patterns of the plant to be pruned. These observations should give you a good idea of how the plant tends to grow, and also how you should prune the plant.

When pruning large camellias, pruning can be a general shaping or shearing of the plants or it can be a severe pruning that significantly reduces the size of the plant. In most instances, camellias out-live the gardeners that planted them, and even though they are considered to be slow growing plants, they can become too large for specific areas of the garden.

Many times, gardeners inherit a wealth of camellias in their gardens when they purchase a previously owned residence. Although these camellias may have been lovingly cared for by the previous owner, it may be necessary to severely prune these plants to restore vigor or to create a different definition in the landscape for the new owner of the property.

Severe pruning should be done just after the plant has finished blooming. In some instances where the required pruning would be drastic, the pruning may be done towards the end of February even if the plant has not finished blooming. Severe pruning of camellias is generally thought to involve the removal of one third to one half of the existing plant. However, in some instances, this severe pruning could be even more drastic. In most cases, the plant should have no problem recovering from such a major pruning, and the pruned plant should quickly begin to grow with vigor.

If severe, pruning is necessary, it must be realized that the plant will shift its focus in the short-run from setting flower buds to growing vigorously, and it is very likely that the camellia will have few if any bloom buds during the season following the major pruning. During the second season following the severe pruning, the camellia should resume normal bud setting, and the plant should have healthier blooms because of the increased vigor in the plant.

It is important to always use sharp tools when pruning Camellia Kanjiro or any plant for that matter. Knives, hand cutters, saws, and shears should be sharpened if necessary before pruning any camellias. A sharp cut will heal quicker than a jagged cut, which will also minimize the likelihood of disease investing a cut during pruning. It is generally recommended to not use power equipment such as gas hedgers to prune camellias.

Prune limbs flush to the feeder branches without leaving nubs. These leftover branches could eventually provide host for disease to enter your camellias. Many gardeners apply a pruning sealant or paint to all cut surfaces after pruning, but that practice is generally not necessary.

Pruning large camellias may be minor or major. Its general purpose is to maintain or restore vigor to the plant. Large camellias that have been severely pruned have the advantage of a large root system that has excessive capacity, and its roots are capable of supplying all of its energies to a smaller number of branches and foliage. This enables the plant to increase its vigor, and become healthier. Pruning large Camellia Kanjiro Shrubs that are well established will enable the plant to have continued vigor, and lead to many more years of supplying beauty to the landscape.
