Indoor hops - special features

The hops, also known as Beloperone guttata, grow as subshrubs and have overhanging shoots and soft, velvety leaves. The original home of the hops is in Mexico. The plant has also become native to Florida. The Justicia brandegeana is valued for its striking red-brown inflorescences. A special feature of the indoor hop is an extensive growth phase. The flowers delight the eye for a whole ten months and are continuously formed.

Indoor hops (Justicia brandegeana)
Height:30 - 60 cm
Blossom:February - November
Location:bright, sunny, no blazing sun
To water:abundant in summer, but no waterlogging
Fertilize:in the growth phase every 2-3 weeks
propagation:possible through cuttings

Find the right location

In order to grow into an attractive and abundantly flowering subshrub, the room hops need a lot of light. The plant should get a few hours of sunlight a day. The blazing midday sun is not tolerated. If the plant stands by the sunny south window, it needs appropriate protection. In summer, room hops thrive at normal room temperatures. Temperatures around 15 degrees are preferred during the cold season.

" Tip: If the location is too warm in winter, leaves will fall.

The plants are sensitive to frost. Temperatures in the single-digit plus range are poorly tolerated.

Choose the ideal substrate

The undemanding room hop thrives in normal potting soil. If you want to make the substrate yourself, the plant is just right with a mixture of garden soil, clay and compost.

Plant and repot hops

When planting, make sure to use a sufficiently large planter. Then the hops have to be repotted less frequently. Since the plant is sensitive to waterlogging, it is helpful to install drainage in the bottom of the container. A layer of gravel or shards are suitable for this.

Planting room hops step by step

  1. Select planter
  2. Use drainage
  3. fill in some substrate
  4. Insert the plant in the middle
  5. Fill in the substrate
  6. Lightly press on the earth
  7. Water the plant well

" Tip: The right time for repotting is early spring, when the shoot has not yet started.

The following signs indicate whether transplanting is necessary:

  • There is hardly any substrate left.
  • The substrate has collapsed.
  • The plant pot is completely rooted.
  • The roots are clearly visible on the surface.
  • The roots emerge from the bottom of the vessel.

Transplant room hops step by step

  1. Select a larger planter
  2. Provide substrate
  3. Remove the plant from the old container
  4. Detach the substrate from the roots
  5. Control roots
  6. Place drainage in new planter
    1. Fill in the substrate
    2. Insert the plant
    3. Fill in the substrate up to the edge of the vessel
    4. Lightly press on the earth
    5. Water the plant
    The hops must be carefully removed from the old planter. If transplantation has been neglected, the roots may completely fill the plant pot and literally blow it up. In order not to injure the root ball, the planter should then be better destroyed.

    When the plant is stuffed, the used substrate is completely removed. Repotting offers the gardener a good opportunity to convince himself of the condition of the root system. Dead and dead root parts are removed. If necessary, intact roots can also be easily shortened and shaped.

    As a rule, room hops tolerate repotting quite well. In order to protect the plant, it is advisable to set up the planter in a protected and shady place for the first two weeks after the planting action.

    Water room hops correctly

    The water requirement of the indoor hop is quite high, not least due to the extended growth period. The earth must not dry out. Proper irrigation requires a lot of tact. If too much water is poured, waterlogging occurs and the roots are attacked. If there is no reaction in time, the entire plant may die.

    " Tip: Tap water does not get limy tap water. Stale room warm water or rainwater should preferably be used.

    Watering is only sporadic during the short resting phase. However, the earth must not dry out completely.

    Fertilize room hops properly

    The plant's nutritional requirements are correspondingly high during the growing season. Liquid fertilizers for green and flowering plants are administered at monthly intervals. Fertilization is slowly discontinued in October. The supply of nutrients can be resumed at the end of April.

    Cut room hops

    The hops grow as a 60 cm high subshrub. So that the plant appears bushy, it is pruned annually. By regularly shortening the tips of the young plants, branched growth can be encouraged.

    Increase room hops

    The propagation of the hops can be combined with the annual pruning in early spring. The removed shoots can be used for the propagation of cuttings.

    Proceed as follows:

    1. Cut the cutting
    2. remove the lower leaves
    3. Stuck shoots in the ground
    1. irrigate sparingly
    2. cover with a plastic hood
    3. Wait for rooting
    The cuttings are brought to a maximum length of ten centimeters. Care should be taken when removing the lower leaves. The shoot is cultivated in a sand-peat mixture, which is well moistened. Root formation will take approximately six to eight weeks. Very little is poured during this phase.

    " Tip: A foil cover keeps the moisture in the soil and creates an advantageous microclimate.

    If the first shoots appear, this is an indication of successful propagation. If you want to quickly grow a bushy and lush plant, place several cuttings in a planter as described.
