Planting+

In the spring, plant the Gladioli 'Black Jack' bulbs about 7-10 cm deep and approximately 10-12 cm apart. Prepare a suitable hole and sprinkle the bottom with a layer of sharp sand to allow rainwater to drain well below the bulbs as Gladiolas prefer rich, well-drained soil. Improve garden soil by mixing in a garden fertiliser. Sprinkle some lime on the soil during the winter. Lighten heavy soil with some sharp sand before planting. These large-flowered Gladioli 'Black Jack' like to grow in a warm, sunny area.

Gladioli 'Black Jack' make a great combination plant

These large-flowered Gladioli 'Black Jack' have a striking, deep red colour. You can create special combinations along your border by planting a group of Gladioli 'Black Jack' next to Cosmos 'Flamingo' or Dahlias. A very natural effect occurs when combining with ornamental grasses, such as Japanese Blood Grass (Imperata Cylindrica 'Red Baron'). This large-flowered species also makes great cut flowers.

Care+

Fertilise your Gladioli 'Black Jack' regularly to allow for the growth of new flower buds. It is a good idea to add fertiliser when watering. Stop fertiliszing three weeks after flowering. The stems of Gladioli 'Black Jack' can be very heavy and sometimes need some support. Completely cut off its faded stems. Plant Gladioli 'Black Jack' preferably in a different place each year in nutritious soil.

Keeping gladiolus through the winter

Gladioli 'Black Jack' bulbs can easily be preserved during the winter. After the first night frost, cut off all stems 10 cm above the bulb and let them dry. Shake the soil off the bulbs and place them in a box of compost and sharp sand. Store the box in a frost-free area. Attach a label with the name of the Gladioli 'Black Jack' to remind yourself for the following year. By the following spring, you can plant your bulbs again and Gladioli 'Black Jack' will reward you once again with its beautiful flowers.

Extra+

Would you like to use your Gladioli 'Black Jack' as cut flowers? Pick them when the lower flowers begin to open, preferably early in the morning. Immediately place the stems in a bucket full of lukewarm water with cut flower food. Due to its strong stems, the Gladioli 'Black Jack' can 'reach' for water easily. Here is an extra tip: plant an extra group of Gladioli 'Black Jack' two weeks later. As a result, the flowering period in your garden will be extended.
