Radiate Broom - Plant, nurture and multiply

The Content Of The Article:

The ray broom is often visited by bees in early summer and also looks good in the bucket. In addition, it is very robust and easy to clean.

Jet broom

The ray broom is commonly referred to as ball broom and belongs to the legume family. The plants are characterized by a dense growth, with growth heights of about one meter can be achieved. Between May and August, the pretty golden yellow flowers show the broad bunting typical of the broom. The legumes are about five inches long and are silky hairy on the outside. In natural gardens, the broom from Southern Europe is a welcome guest. Everything you need to know about the care and cultivation of the radiation ghost is explained below.

Origin of the radiation ghost

The ray broom originates from the Southern Alps, the Apennines and the Balkans. There, the plant likes to appear in company with the Scots pine, preferring dry and rocky slopes. The plant was first described in the mid-18th century. The Radiate Gorse (Genista radiata) is considered a true broom. Not to be confused, the plant with different plants, which are also called brooms, but belong to other genera. These include, for example, the brooms, a representative of the Geißklees, the gorse, which belongs to the genus Ulex or the Binsenginster of the genus Spartium.

Appearance of the radiation ghost

The radiant appearance of the branches gave the shrub its name. The leaves are threefold and grow opposite. In its natural range, radiation broom occurs at altitudes up to 900 meters. The plants grow comparatively fast and in all directions. At about four years the plant has reached its maximum growth height. The flowers are reminiscent of butterflies. While the ray-broom flowers golden yellow, other representatives of the plant family can also flaunt white, orange or red flowers.

When does the Radiate Broom bloom?

The golden yellow flowers appear between May and August. This produces flowers and head-like flower clusters. The single flowers have a diameter of about ten centimeters. The grapes can grow about five inches long. Except for a hairy median strip, the outstretched flag of the flowers is bare. The densely hairy dark brown pods conceal up to five seeds reminiscent of lentils.

Planting Radiate Broom - you have to take this into account

The ray broom is a real asset to beds and discounts. The plant grows fast and makes few demands. What you should consider when planting, you will find below.


At the location of the ray broom makes no great claims. The plants are used to thriving even in nutrient-poor locations. On the other hand, the plant appreciates a sunny spot. The full sunshine is well tolerated and promotes a lush flowering. If the ray-broom is planted in the shade, he will miss his much-desired growth and probably no flowers.

When selecting the location, it should also be noted that the ray broom expands not only in height, but also in width. Enough distance to neighboring plants is therefore an advantage, because older plants are difficult to transfer to another location without the plant being damaged. By the way, in the company of junipers the ray-broom feels particularly well.

❍ Substrate:

The demands on the ground are low. However, a dry soil is a prerequisite, because if it is too moist, it will quickly cause the roots to rot. A light and permeable soil is an advantage and prevents waterlogging at the same time. The soil should best have a pH between 4.5 and 6.5, because in a neutral to slightly acidic soil, the plants thrive especially well.

❍ Planting instructions:

Planting time for the ray broom is year round. So you can plant it on all frost-free days. A little tip: If you prefer to buy bale plants, because root-bare plants are more sensitive and often grow worse. When planting, proceed as follows:

  1. Select location.
  2. Loosen the soil and free it from weeds and stones.
  3. Dig out the planting hole at least twice the size of the root ball.
  4. Insert plant.
  5. Fill substrate and lightly solidify.
  6. Cast on well.

Important: Make sure that the irrigating water drains well, as the ray broom can not tolerate waterlogging.

Transplanting Radiate Broom - a difficult task

The location of the ray-bastard should be chosen carefully, because transplanting usually does not get the shrub. Young plants are even less sensitive.But once the roots have become firmly anchored in the soil, it becomes difficult to transplant the shrub without damaging the roots, which inevitably leads to the plant dying. If it is still necessary to implement the ball broom, you should carefully dig up the entire root ball. Try not to hurt the roots and immediately plant the gorse in its new location.

Keep ray broom as a container plant

If you do not have a garden and you do not want to miss out on a radiation broom, you may consider cultivating in the tub. However, there are some things to keep in mind:

β‡’ Since the plants should not be repotted if possible, you must select the planter in sufficient size.

β‡’ Incorrect casting behavior can quickly lead to waterlogging in container plants. Therefore, you should provide at the bottom of the vessel with a drainage of potsherds or gravel.

β‡’ The planter can be placed in a sunny and warm location. In winter, the container plant should move to a sheltered location and kept as frost-free as possible.

This is how to properly care for the ray broom

To water:

The ray broom makes low demands on the hobby gardener and thereby becomes a self-sufficient. The tap roots retract, e.g. the required moisture from the soil. Longer dry periods are therefore usually no problem for the plants. On hot days, you can pour moderately. However, waterlogging should not occur. Container plants have a higher water requirement and should therefore be watered regularly. A drainage in the planter prevents waterlogging, which would quickly lead to the death of the plant.


As a rule, the plants do not need any additional fertilizer as all the necessary nutrients are taken up from the soil via the tap roots. In order to promote flowering, commercially available liquid fertilizers for flowering plants can be used sparingly.

Rear section:

The lush growth of the broom plants does not always happen to the delight of the garden owner. Radiant broom is spreading rapidly due to its spreading branches and can form whole colonies by spontaneous rooting of ground-level shoots. Cutting measures seem so inevitable, but this should be done with care. Radical cuts even take the plant nauseous. Therefore, distribute cutting measures to fall and spring instead of overstraining the plant with a radical pruning.

If only the tips are slightly trimmed, this has a positive effect on flower formation. The annual pruning you can use to bring the ball broom in its typical round shape. A pruning can be done down to about 40 centimeters. The flowering will do no harm. Most of the flowers develop in the following year on the young shoots. When pruning you should also remove the same old wood. Old wood is clearly recognizable by its brown color.

Important: Always wear gardening gloves when cutting the ray broom. The escaping plant juice can cause skin irritation and harm allergy sufferers.


Radiant broom is generally considered robust and hardy. However, this statement can not be universally generalized. Winter protection certainly plays a role in some plants:

❍ young plants:
Young plants are even less robust in the first two years after planting and should receive winter protection. If the soil around the roots is covered with brushwood or deciduous foliage, these plants will also get through the cold season.

❍ potted plants:
Those who cultivate the ray broom in the tub, should remember that potted plants are particularly sensitive to frost. On a wall or house wall, the plants are protected from snow and ice. Positioning the planter on a styrofoam or wood base will provide extra protection against the delicate roots.

Increase radiation broom - That's how it works

The multiplication of the ray broom can be done quite simply. There are three methods to choose from, which will be presented in more detail below.

Propagation by cuttings:

The best time for the propagation by cuttings is the late autumn or early summer. The annual pruning can also be used for the production of cuttings. The cuttings should be brought to a length of 15 to 20 centimeters. In a planter, which is filled with a potting soil-sand mixture, the cuttings are then rooted. This should be done in a bright place and at room temperature. The soil must then keep evenly moist, but not too wet! Also, the bright sunlight is not beneficial for the cuttings. After a few months, sufficient roots will have formed to put the young plant in the desired location in the open air.

Propagation by seeds:

Another possibility is propagation by sowing.You can take the seeds you need from the already existing plants or even buy them at retail. In the late summer you can sow the seeds. The immediate sowing in the field is also possible as well as a drying and storage over the winter and a sowing in the coming spring. Proceed as follows:

Keep the seeds evenly moist. A few weeks pass before germination. If the plants have reached a stature height of about ten centimeters, planting can take place at the desired location.

Propagation by sinker:

Anyone who already owns a mother plant can make propagation very easy. If the shoots touch the ground, the ray broom will quickly form new roots there. The resulting young plants can be easily separated and planted directly in a new location.

Detect diseases and pests on the radiation broom

With diseases and pests, the extremely robust plant has virtually no problems. Occasionally there may be frost damage due to incorrect wintering. This can happen, for example, when potted plants have not received winter protection and the sensitive roots are exposed to the cold. Even a too late pruning in autumn can make the plant prone to frost damage. If potted plants are wintered in a sheltered location and sensitive young plants are given an extra layer of foliage or brushwood to protect the roots, you should enjoy healthy and vigorous plants throughout.
