Clematis triternata Rubromarginata planting and care
The main thing you need to know about growing Clematis triternata rubromarginata is that it is quite heat-loving and not very winter hardy. The USDA zones for this clematis are 5 through 9. This means that Clematis rubromarginata will grow fine in the UK and winter well in most regions of the United States, such as Oregon and further south. But in Michigan, the Dakotas, Minnesota, and Canada and northern European countries, you will need to cover it carefully. This is not very difficult, because this variety belongs to the 3rd pruning group. By the way, young plants sometimes survive the wintering and without covering, but with age, winter hardiness somehow decreases.
How to plant clematis
For planting Clematis flammula triternata rubromarginata you will need a fairly large planting pit. It should be about a foot and a half long and wide, and about the same depth. If you are in states with cold winters, it is best to choose well-lit locations on the south, east or west side of the wall for this clematis planting. If possible, they should be protected from the wind. If you are in warm states, clematis, on the contrary, should be protected from direct sunlight. First of all, you should protect its roots from overheating: therefore, planting clematis near the north wall of the house will be a good solution.
The soil for growing clematis should be loose, well cultivated, with a high humus content and well drained. Loamy or light loamy soils are suitable. The clematis planting hole should be filled with the soil that was removed from it. Mix this soil with compost or humus in a ratio of 1:1, add a little complex fertilizer with a high content of phosphorus and potassium. You can also use about one ounce of superphosphate and one ounce of potassium sulfate per planting hole instead of a compound fertilizer.
When to plant clematis Rubromarginata?
The best time to plant clematis is in early fall when the soil temperature is about 68 degrees Fahrenheit. You can also plant it in the spring, but only before the clematis is actively budding. In the summer, you can only transplant the plant with a clump of soil.
If you have a fairly mature plant with stems that are woody at the bottom, it is better to plant it with one or two buds buried so that the plant produces more shoots. If you have purchased a very young clematis, it is not necessary to deepen it.
After planting the clematis must be watered so that the earth is tamped and tightly adhered to the roots.
Care of Clematis triternata Rubromarginata
Watering
Rubromarginata clematis does not need watering very often. It should only be watered if you are experiencing a prolonged drought. It is better to water it with soft water, rarely but abundantly, pouring 10 liters or more at once. You can pour about half as much under a young plant.
Mulching
All clematis respond well to mulching the soil with grass clippings or other organic materials. This both prevents the soil from overheating in warm summers and protects the roots from freezing if you have late frosts. The mulch also protects the soil from excess moisture evaporation and prevents weeds from germinating.
Fertilizing
- In the first year after planting, at the very beginning of vegetation, you can apply about 5 grams of nitrogen fertilizer in the form of a solution. Nothing else is needed, everything else you need is already in the planting hole, if you have prepared it correctly. In the future clematis Rubromarginata should be fertilize every year, at least four times, because every year it will completely renew its green mass.
- The first feeding with a complex fertilizer with a predominance of nitrogen is carried out at the beginning of vegetation, when clematis starts to grow actively. In addition, at the same time you can also apply organic fertilizers in the form of humus or compost.
- The second feeding is carried out at the beginning of budding. In this feeding you need to make balanced fertilizers, in which nitrogen is about 2 times less than phosphorus and potassium. For example, for an adult clematis bush, the nutrient requirements for the second top dressing are 5 g (about 1/6 ounce) of nitrogen, 10 g (about 1/3 ounce) of phosphorus and 10 g of potassium by active ingredient. Feeding it with a full complement of macro and micronutrients will also be beneficial.
- At the height of flowering, when there are a lot of flowers, you should reapply the same fertilizer: about 5 g nitrogen, 10 g phosphorus and 10 g potassium plus micronutrients.
- The fourth and final fertilization is carried out at the end of summer. Introduce 5 g of phosphorus and 5 g of potassium, as well as a complex of trace elements. This will help to better prepare the plant for winterization.
This will be enough to ensure that your clematis blooms very profusely.
