Overwintering Nasturtium - Surviving Cold weather

There are different varieties of nasturtium, some are perennial, while many hybrid varieties are annual. This ensures a lot of variety and a large variety of colors in the flower bed. Not all of these varieties are hardy.

Many garden owners simply let the perennial nasturtium freeze and sow again in the spring. Since the seeds are quite cheap or even collected from your own plants, this method is cheaper than overwintering and also less expensive.

How to overwinter nasturtium?

Balcony or terrace plants only have to be placed in a suitable place to overwinter. It should be frost-free and light throughout the winter. A heated greenhouse or conservatory works well for this. Only water your nasturtium moderately and do without fertilizer altogether.

The most important winter tips for your nasturtium:

  • bright and frost-free
  • water moderately
  • do not fertilize

Tips 

Overwintering is particularly worthwhile for rare or unusual varieties.

I studied horticulture at the University of Guelph and in my free time I plant everything that has roots on a piece of land. The topic of self-sufficiency and seasonal nutrition is particularly close to my heart. Favorite fruit: quince, corner, and blueberry Favorite vegetables: peas, tomatoes, and garlic
