A feast for the eyes are undoubtedly flowering shrubs of the family of the pea family and legumes. Well known are some representatives of this species, such as gold and blue rain or acacia. The luminous flowering of these trees is usually limited to spring. But a relative of this plant family is particularly striking: the indigo shrub (Indigofera heterantha). Hobby gardeners admire this shrub because of its long flowering period, which lasts from June to September.

The wood is more commonly known in tree nurseries as Himalayan indigo bush or false indigo. These names refer, on the one hand, to the origin of the shrub, the Himalayas, and, on the other, to the fact that this butterfly plant is not a dye plant, like its relative Indigo tinctoria.

In contrast to the blue wisteria, the shrub with its pink and perennial flowers is also suitable for the small garden, as it can be cut back to any size.

Striking features of the indigo bush

The summer flowering, loose shrub grows up to 150 centimeters high and can even reach 2 meters in particularly mild conditions. Its pink flowers unfold as 5 to 10 centimeters long and overhanging grapes. Petite the striking feathery leaves, which have up to 21 leaflets.

A deep, slightly branched root gives the indigo shrub a firm hold in the soil.

Planting indigo shrub - that's what matters

Location:

A sunny and sheltered location in mild locations thanks the flowering shrub with an optimal growth. It is best to place it in front of a warm wall.

The Himalayan indigo bush is only partially hardy. Therefore, it is advisable to cultivate the plant in the large tub in areas with harsh climates, which receives an exposed place on a sunny terrace.

❍ floor:

Whether the indigo shrub is planted in the field or in the tub, the soil should be impermeable to water. Waterlogging does not tolerate waterlogging. In case of doubt, mix sand or gravel in the field, or use expanded clay to grow the container. Otherwise, the soil should be moderately dry to earth-moist.

❍ Planting time:

The ideal time to plant the summer flowering shrub is in spring. This has the following advantages: they can enjoy the bright flowers over the summer and can root well until autumn.

You can also plant the indigo shrub as a container plant throughout the year, but not in frosty conditions.

Planting instructions:

  1. Pick up a planting hole that is twice as large and deep as the size of the root ball.
  2. Now loosen the bale gently and place it in the water so that it absorbs moisture properly.
  3. Then place it in the prepared hole and fill it with the excavation.
  4. Finally, the soil is still pressed and the planting watered. So that the water does not run away superficially, it is advisable to create a casting ring around the young plant.

"Planting tips for the bucket:

  1. Choose a big bucket. He should have the same diameter on the ground as on the upper edge. As a result, the tilting of the planter is reduced.
    In addition, there must be a hole on the bottom of the bucket, from which excess water can drain off after pouring.
  2. Place a piece of pottery on the top of the hole and fill the floor with a layer of coarse gravel 2 centimeters high for drainage. Over it, add a layer of the substrate, mixed with a little expanded clay.
  3. Place the root ball in the bucket and check whether the planting depth is sufficient. Otherwise, balance those with the earth mixture.
  4. Now gently loosen the bale and place it in the water so that it absorbs moisture well.
  5. Then place the moist root ball in the bucket and fill it with the remaining substrate mixture.
  6. Do not forget: Press the soil in the planter and add the indigo plant.

How to maintain the indigo bush

Pouring and fertilizing:

Pour the shrub in the field regularly, so that the soil does not dry out too much. But make sure that the plant is not too wet. For fertilizing, you give your shrubs compost in March and end of June.

Container plants have a larger water requirement. On the surface of the pot, allow the substrate to dry only lightly on the surface and then pour. The soil in the bucket must not dry out, nor accumulate waterlogging.

You cover the nutrient requirement with a liquid fertilizer for potted plants (My recommendation: COMPO balcony and container plant fertilizer).

Rear section:

The butterfly is cut in spring before the new shoot.You can shorten the shrub by about one third. Later, you should no longer encounter the shrub with the scissors because the flowers generally develop on the new shoot.

Radical except for a few buds on the ground of the Indogostrauch is zurückgeschitten when in winter the frost has staggered most impulses.

Wintering:

How you overwinter the blooming wood depends on whether it was cultivated in the tub or in the field. It is best to overwinter the indigo shrub in the bucket in a cool room. It does not matter if he is light or dark, because he throws off his leaves anyway.

The bushes planted outdoors tolerate temperatures of up to -15° Celsius for a short time. Play it safe and protect your plant by covering the rootstock thickly with leaves and needle twigs. If the shoots freeze and the rhizome survive, then the indigo shrub in the spring again.

Also cover the crown of the shrub. This will protect you against frost on the one hand and against the ominous power of the winter sun on the other hand.

"By the way: The Indigofera heterantha is very rarely attacked by diseases and pests.
