Vanilla flowers like a warm spot in full sun. A semi-shady place is possible, but the abundance of flowers is lower here. If possible, the site should be sheltered from rain and wind. When there is a lack of light, the summer flower drives long horny shoots and only small flowers.

This is how you experience the scent of the vanilla flower plants in the best possible way.

How do I plant my vanilla flower?

For a rich abundance of flowers, repotting the plants or planting them out in the garden after purchase is recommended. The volume of soil in the culture pot is too small to supply the vanilla flower over the summer months. It is therefore important that the balcony plant has a larger volume of soil with high-quality potting soil. A pH of 5.5 to 6 and well-drained soil is optimal.

Our gardening tip: At least 2 to 3 liters of soil are required for each vanilla flower. With less soil volume, the maintenance effort increases significantly and the aromatic plants cannot develop optimally.

Heliotrope care essentially consists of regular water supply, fertilization and the removal of faded flowers. The plants branch very well on their own and grow bushy. A cut is not necessary, but you should remove faded flowers in good time. This prevents seed formation and the planting looks well-groomed and appealing. Be aware that heliotrope are not hardy. Planting is therefore only recommended after the last late frosts, and in autumn it is important to move the popular summer flowers to their winter quarters in good timeto deliver. With the right knowledge, you can overwinter vanilla flowers. However, it takes some effort and newly purchased specimens are often more vigorous and floriferous.

How do I water my vanilla flower properly?

Vanilla flowers need a steady water supply for good development. When it is dry, the summer flowers quickly let their leaves droop. It is important that it never gets too dry, because heliotrope does not tolerate drought. Immediately after planting, the water requirement is still low. Once the flower is established and temperatures are rising, daily watering may be necessary. How often you have to water depends largely on the temperatures, the precipitation, and the storage capacityof the soil and the volume of soil in the vessel. Vanilla flowers planted in the ground require a little less attention than specimens in pots. Water storage boxes help minimize the labor involved in watering. It is important that the substrate dries a little before watering again.

Our professional tip: Vanilla flowers are sensitive to waterlogging. Make sure that vessels have a water drainage hole and that there is never standing water.

How do I properly fertilize my vanilla flower?

With optimal nutrition, vanilla flowers grow and bloom from May to October. When planting the balcony plants, use high-quality potting soil and a long-term balcony flower fertilizer. This gives the flowers a good start and the balcony plants are well supplied with nutrients for the first 4 to 6 weeks. From mid-June, we recommend weekly fertilizing with Kölle’s Beste Flower Fertilizer with Guano or Kölle’s Beste Bedding and Balcony Plant Fertilizer with humate. Both are liquid fertilizers that you add to the irrigation water according to the instructions on the package. Long-term fertilizer sticks are also suitable for individual pots, which supply the vanilla flowers with the nutrients they need for 3 months.

What pests and diseases can the vanilla flower get?

With the right site conditions and optimal care, Heliotrope are robust bedding and balcony plants. If vanilla flowers have brown leaves, it is usually a result of too high a dose of fertilizer or damage due to drought. The following pests can occur:

aphids

Vanilla flowers are more susceptible to aphid infestation, especially in phases with less light and less growth. Rinse the plants thoroughly with water at the first infestation. This first measure usually helps. In addition, strengthening with Kölle’s organic plant treatment helps. The biological agent with garlic strengthens the plant ‘s own immune system and helps in a natural way to reduce pest infestation.

white flies

The small white pests are a problem, especially in wind-protected, warm locations and in winter quarters. The whitefly can be found on the underside of the leaf and yellow spots form on the foliage due to its sucking activity. The yellow leaves dry up and fall off. At the first infestation, remove the affected leaves and dispose of them with household waste. If the infestation is low, you can fight the whitefly on the balcony plants with yellow panels. Targeted use of beneficial insects is very effective in closed rooms.
