In addition to many other plants, conifers line up in the pollen of popular potted plants. For cultivation in a larger pot, thuja, cypress and rocket juniper are equally suitable. Its soft foliage varies from light to dark green to bluish hues. Whether as a solitaire or in a group, conifers in the bucket are extremely charming.
What are conifers?The term within biological classification consists of the Latin words "conus" for "cones" and "ferre" for "carry". Both connected with each other results in the term "pin carrier". In German usage, however, the term "conifers" has prevailed. In professional circles is occasionally talk of Coniferales or Pinales. The cones are female fruit stands in the form of ears, which lime over time. Seeds ripen under the scales. In the case of trees and cypresses, the fruits have the shape of a berry. Nevertheless, the correct definition is cones. This also applies to the juniper, in which the scales are fleshy and develop into a pea-sized fruit.
What are the advantages of conifers?Conifers are indispensable in garden design. The popularity is not by chance, because conifers come up with a series of convincing arguments:
- evergreen (exception: larch)
- provide privacy throughout the year
- no falling autumn leaves
- green splashes of color in winter
- frost compatible
- easy care
As protection against drying up during the cold season, deciduous trees shed their leaves in autumn. Needles are covered with a thick layer of wax and have a low surface area, which significantly reduces evaporation. That's why conifers can keep their needles in winter. For the shed leaves of cypress family the same principle applies.
Why cultivate conifers in the tub?
Because everywhere, where there is a lack of space, offers the Kübelhaltung. In contrast, there are the garden owners who prefer a planter despite large footprint for various plants. The possibility of a plant being pushed aside or being transported to another location when needed can sometimes be very useful. Here are a few suggestions of pitches where conifers in the bucket are excellent:
- right and left of the entrance
- next to a staircase
- for bordering a bank
- front of the house
- Decoration of the terrace
- on the balcony
- as a delineation for separate areas
Size of the bucketThe pot emphasizes the natural expressiveness of the conifer. What size should he have, so that thuja, cypress or other coniferous trees thrive in him magnificently? A rule of thumb states that a bucket diameter of 30 to 40 cm is required for one meter of plant height. Higher conifers need more volume. Conifers are commonly flat-rooters, yet the minimum in the vertical should correspond to the width. For even very small trees, twice the height and width of the root ball is sufficient. If the plant grows in size over time, a move to a more spacious container is due.
Tip: If possible, select the pot a little larger so that the needle plant can gain a foothold.
Which bucket?The bucket for the conifers must first and foremost please. But before only the personal taste affects the purchase decision, you should also worry about the material. At the moment the specialist trade offers bucket in the following materials:
- Terracotta: often not hardy
- Earthenware / Ceramics: fragile, not frost-proof
- Concrete: heavy, unwieldy
- Zinc: durable
- Plastic: lightweight and inexpensive
- Poly rattan: modern
- Fiberglass: high strength
- Aluminum: robust, low weight
- Stainless steel: looks very noble
- Rustproof steel (Cortensteel): rustic
- Wood: insulating, close to nature
- Bamboo: decorative
Moist soil expands when frozen and blows up pottery and ceramic pots. For plastic, it is advisable to pay attention to the note "UV resistant". Without this property, the colors fade when exposed to sunlight and the material becomes brittle. Lacking the predicate, which points to light fastness, bucket look after a season old and worn out.
Conifers substrateIn the bucket, plants can not make full use of the soil. Unlike free-range planting, they are dependent on the amount offered to them in their habitat. However, to be bursting with health, they need a substrate that provides them with all the essential nutrients. Commercial special soil for conifers has the characteristics expected of the plants:
- slightly sour
- ph value 3.5 - 4.5
- stores moisture
- mostly supplied with starter fertilizer
Thuja, cypress and rocket juniper in the bucketCypress family, which include from a botanical point of view also Thuja and juniper, look due to their flaky leaves in general more full-bodied than the native conifers fir, spruce and pine. The denser growth makes these conifer genera to gladly seen components in the garden. The essential oils in the leaves and young branches also spread an aromatic scent. In principle, species that grow only slowly and not excessively should be preferred for bucket keeping. Please take into account that the plants require a little more care than in the free-range and, in order to prevent frost damage, may need a heat protection looped around the bucket in winter.
1. Immerse roots of container plants in water until no more bubbles appear
2. place rootless plants in water for at least one hour
3. Equip the bucket with a 2 cm layer of drainage (gravel, potsherds, expanded clay)
4. If necessary, insert a fleece as a delimitation to the earth
5. Fill in a layer of conifer substrate
6. Place the plant in the middle of the bucket
7. pour earth around the roots
8. Press the substrate
9. Leave 3-5 cm to the edge of the bucket (so that the bucket does not overflow when it is being watered)
10. Pour well
MoireIn the field, dry weather is usually not a problem for conifers, unlike plants in the pot. During heat and longer rain-free phases, the water supply quickly comes to a standstill due to the limited volume in the bucket. Make sure that the earth always has a certain moisture content. During the summer, the watering can may need to be activated every day. The good too much can also have a negative impact. Extreme wetness promotes mold growth and hinders the roots from absorbing nutrients. Watering properly means:
- wait until the earth has dried
- Do not wet the above-ground parts of the plant, but pour directly onto the substrate
- Water temperature not colder than ambient temperature
- water in the morning or evening - not at midday heat (water evaporates immediately)
- in the summer usually daily watering necessary
- Spring and summer: about twice a week
- do not leave water in the coaster for a long time (waterlogging!)
- even in winter take care that the earth does not dry out (do not pour in heavy frost)
Initially, fertilization is not necessary as the conifer substrate will initially provide enough nutrients. After 2-3 months, this stock is used up. In order to avoid deficiencies in the crop, you should then feed the conifers over the irrigation water every four weeks with liquid fertilizer.From the end of August fertilization is stopped, so that the plant can prepare for the winter. Only in early spring are the next nutrient doses due. Fertilizers with long-term effects only have to be applied once or twice a year.
Tip: From time to time dry coffee grounds and work them into the substrate. The residue in the coffee preparation contains nitrogen, phosphorus and potassium, among others, and has a slightly acidifying effect.
Thuja - Special features:
- Location: sunny to partially shaded
- reacts if necessary prone to drafts
- regular cut for dense growth
- relatively hardy
- Dwarf shapes: "Teddy", "Tiny Tim" and "Little Giant"
- choose hardy cypresses
- Add some sand to the soil
- Location: sun or partial shade
- needs winter protection when holding the bucket (wrap the pot with bubble wrap, coconut mat or sackcloth)
- short style: "Baby Blue"
- typical heath plant
- Location: as sunny as possible
- grows upright
- good frost tolerant
- loves nutrient-poor soil (fertilize only slightly!)
Further care measuresIt will certainly not be that after some time weeds grow next to the plants. If it is still small, it can be easily weät. On this occasion, loosen the earth with a hand pick or a fork so that oxygen can penetrate to the roots. But be careful that they do not hurt roots. Thuja, cypress and juniper plants are very cut tolerant. If the trees in the bucket blow up the originally intended frame, you can grab the scissors, but not into the old wood, because there the branches do not drive out.
Rather often leans less than once radically. Ideally, cutbacks take place in spring or autumn. With imagination, patience and possibly with the help of a stencil, interesting shapes and sculptures are created. The rocket juniper grows up as a slender pillar. In this conifer usually only the above shoots are shortened.
Tip: If the bucket size is sufficient, planting with low flowering plants (eg pansies or verbenas) ensures color. If you decide on bulbous plants (crocuses, mini-daffodils), you should plant them already in the fall, because they need a cold period before they bloom.
