Plagued by doubts, amateur gardeners stand in front of withered Bidens in late summer. Actually, throwing away the magnificent balcony flowers is a shame. Can you overwinter two teeth? This guide explains how and where you can successfully get Biden's Goldmarie through the winter.

Bidens should be cut back before wintering

Bidens - hardy? No - perennial? Yes

In plant sales, Bidens are simply declared as annual balcony flowers. In fact, the summer perpetual bloomers are extremely sensitive to frost, especially the picturesque Goldmarie with hanging, yellow cascades of flowers. In their tropical home regions, bidens (Bidens) are of course highly valued as perennials with the floral power for growth over several years. This fact throws the door wide open for hibernation behind glass. The following instructions explain step by step how to do it correctly.

Winterizing Bidens - step-by-step instructions

Early preparation prepares Bidens for winter behind glass. Other important criteria guarantee a successful hibernation: the right time to let them in, expert pruning and winter quarters with the perfect framework. How to properly overwinter Bidens in 4 steps:

Preparation in late summer

At the end of September, the Bidens Flower Festival is coming to an end. This preparatory work for winter storage is already beginning:

  • Pour Bidens into boxes and buckets more sparingly
  • Stop fertilizing flowers

Bidens are not allowed to move into winter quarters with dripping wet root balls. In order for the shoots to mature, the nutrient supply ends a few weeks before the end of the flowering period.

Cutback - prologue for the winter time

Pruning before wintering will ensure compact, viable growth behind glass. In most rooms there shouldn't be room for the epic long shoots of up to 3 meters in length anyway. How to properly trim Bidens:

  • Best time: just before you leave
  • Cutting tool: sharp, disinfected bypass pruning shears
  • Pruning: Cut tendrils back by half
  • Trimming: remove wilted flowers and leaves

Grant Bidens in time

If temperatures fall below 15 degrees at night, Bidens move to winter quarters. The next morning you can read the lowest temperature of the night from the minimum-maximum thermometer on the balcony or terrace.

Select winter quarters

The framework conditions in the winter quarters are decisive for a healthy hibernation of Biden's Goldmarie and other two-toothed. The location should be like this:

  • Bright and sunny, preferably facing south, west or east
  • Cool to slightly temperate, ideally with temperatures between 12° and 18° Celsius

Bidens cannot hibernate in a dark basement room or cozy and warm living room. Conservatories, greenhouses, hallways or bedrooms are perfectly suited.

Care tips for the winter

Bidens stop growing in winter quarters. The water requirement is reduced accordingly. Allow the substrate to dry before watering the flowers. Continue not to apply fertilizer. Weekly checks for pests such as spider mites and aphids are obligatory.
