Claims to the care

Thanks to its flowers, the Clematis 'Piilu' was rightly awarded the coveted Plantarium Gold Medal in 1998. It is one of the most flowering varieties and the best for plant pots. She is the star at trellises, trellis, pergolas or as facade greening. It is the ideal rose companion, whereby the respective climbing rose should have a growth advantage of 2 - 3 years. All this requires a minimum of care. It starts with choosing the right location.

Location

  • Clematis 'Piilu' loves sunny to partially shaded locations
  • If possible, do not expose the blazing midday sun
  • Shadow the root area permanently and keep it cool and moist
  • Heat and dryness do not tolerate the clematis
  • Cover the root area with a layer of mulch up to 10 cm thick
  • In too sunny locations superficial plantings make sense
  • Best with small shrubs, grasses or dwarf shrubs
  • Record sheets (Rodgersien) particularly well suited as Vorpflanzung
  • Root area of ​​potted plants also shade with matching planting

soil quality

Even if this clematis is very adaptable, it finds optimal conditions in fresh to moist, nutrient-rich, humus-rich as well as well-drained and deep soils. She has to be able to grow deep into the soil. The pH of the soil should be between 5.5 and 7. Heavy clay soil can be made more permeable with abundant sand or gravel.

Clematis 'Piilu' - Clematis


The permeability to stagnant sloping soils can be improved by introducing a drainage. Sandy soil can only store water and nutrients poorly. By adding good potting soil and some rock flour or mature compost, these soils can also be upgraded accordingly.

plants

The Clematis 'Piilu' can be used singly or with other climbers, e.g. Roses are planted, both in the bed on a corresponding trellis aid and in the bucket. When planting, there are a few things to consider in order to create optimal growth conditions for the Clematis right from the start.
In the bed
As long as the soil is frost-free, this clematis can be planted, but preferably in late summer around August / September. At this time, the soil temperature is about 18 - 20 degrees, so that the plant can form a strong root system until winter. This usually has a positive effect on the growth of the plant next year.
  • Before planting, place the clematis in the water bath for about fifteen minutes
  • While making a planting hole
  • That should be about 1.5 times as wide and deep as the bale
  • Thoroughly soil the soil on the bottom of the pit
  • Planting distances of 30 - 50 cm are recommended
  • Depending on the soil conditions, mix the excavated soil with high quality potting soil
  • Remove weeds thoroughly in the planting area
  • For strong root competition, installation of a root barrier advisable
  • Remove the plant from the pot and insert in the middle
  • Insert about 10 cm deeper than before in the pot
  • If necessary, use a climbing aid
  • Then fill with excavated soil and water well
  • After watering, spread a layer of mulch on the root area
Tip: With a sufficiently deep planting the lowest leaf buds are in the soil and are thus protected against frost damages and in particular the dreaded wilting fungi. If the plant is actually attacked by these fungi, it does not completely die, but can drive out of the eyes in the ground again.
In the bucket
In a container planting, one must first pay attention to a sufficiently large bucket. He should have a capacity of 10 liters for a plant and be able to hold 25-30 liters with 2-3 copies per pot.To avoid waterlogging a 5 - 8 cm thick drainage layer of coarse gravel on the bottom of the pot is essential.
Then you give a part of a high-quality potting soil and uses the clematis in the appropriate depth in the middle. Finally fill up to a few centimeters below the edge with substrate, press the soil and water. For shading of the root area use low perennials such as blue cushions or carpet phlox as underplanting.

to water

In general, a young clematis should be abundantly poured in competition with other plants, about every two days in the planting year, about 20 - 30 liters per plant. But even later, this plant does not like dryness. Therefore, always make sure that the soil does not dry out. It is best to pour whenever the top layer of soil has dried. Potted plants need to be watered more often, especially in spring and summer, as the substrate dries much faster.

Fertilize

Due to the strong growth power and perennial flowering the Clematis 'Piilu' needs a strong fertilization. For this special plant fertilizers for climbing plants or a mixture of a good garden fertilizer for roses or flowering shrubs and compost are recommended. These fertilizers contain the mineral Betonit, which helps keep the plants healthy and ensures that Clematis can better absorb moisture to better withstand dry periods. It's best to fertilize in the spring. For potted plants, commercially available slow-release fertilizers and for flowering liquid fertilizers, which are administered via the irrigation water.

overwinter

This forest grape has a very good frost hardiness. Nevertheless, it does not hurt to provide them with a light winter protection. By contrast, specimens in the bucket are not completely without protection. To do this, place them in a protected, not full sun, at best on a wooden pallet or a polystyrene plate. In addition, you protect the root area with a winter protection fleece or covers it with fir twigs.
Tip: About every 3 to 4 years, the clematis 'Piilu' should be repotted after the winter in fresh substrate.

To cut

Clematis 'Piilu' - Clematis

When and how the clematis is blended depends on the respective section group. Clematis 'Piilu' belongs to the twice-flowering varieties and thus to the cutting group 2. This means that you should be a little more reserved when pruning. All shoots are cut back in November / December to about one meter. To promote the second bloom, one cuts off all withered inflorescences after the first flowering with the underlying pair of leaves. About every 4 - 5 years, a stronger pruning is recommended to rejuvenate the plant. Such pruning should also be done on potted plants.

multiply

  • Propagation is possible via offshoots
  • To do this, fill a flower pot with potting soil
  • Choose a strong, not too old shoot
  • Set the pot within reach of the shoot
  • Then bend this shoot down to the pot
  • Lay down on the substrate and cover with soil
  • Fix the shoot with a tent peg or similar in the ground
  • The drive section in the ground should be unexplored
  • Otherwise rotting threatens
  • Bind shoot tip to a bamboo stick
  • Do not allow the substrate to dry out until it has risen
You can also put the shoot directly into the ground, cover it with damp humus soil and fix it accordingly. After rooting the offshoot can be separated from the mother plant and transplanted. It is best left to the mother plant by the next spring, so he has sufficient time to develop a strong root system.

Diseases

Large-flowered hybrids such as the clematis 'Piilu' often suffer from the so-called clematis wilt. It is a fungal disease. Two species of this wilting disease can attack the clematis, the Phoma and the Fusarium clematis wilt.

Phoma Clematis wilt

This type of wilting disease is the more dangerous of the two and the most common. It first shows on brownish leaf spots on the undersides of older leaves and spreads very quickly, especially in a warm and humid climate. It can lead to the death of the entire plant within two weeks.
If the disease is detected early, you may still save the plant by quickly removing all affected leaves and disposed of with household waste. This is followed by a treatment with special fungicides. A sufficiently deep planting of the clematis increases the likelihood that it will expel again after an infestation.

Fusarium wilt Clematis

Infestation with the Fusarium clematis wilt causes the pathways to block and the plants to absorb neither water nor nutrients. They give the appearance, despite regular watering, the appearance to dry up. If an infestation is discovered, infested plant parts should be removed immediately and the plant cut back into the old wood. Clippings should be disposed of with household waste and not on the compost.After pruning, the clematis usually drives out quite quickly.
