For the best quality and results, we recommend planting your bulbs as soon as they arrive. In case you're not ready to plant them right away, especially if the weather is still a bit too warm for certain varieties like tulips, you can safely store the bulbs for later this season.
Make sure they enjoy good airflow and keep them away from warm or damp conditions. Simply unpack the bulbs and find them a cool, dry spot.
We do not (yet) sell 100% organic flower bulbs. However, we work closely with certified growers who are committed to responsible farming practices.
