However, we have lowered our prices to help offset this change.

Additional Delivery Information

  • We dispatch our plants year-round, as most are shipped with soil. During the winter months, we closely monitor weather conditions and may temporarily delay shipments if the weather is particularly severe. Our packing process includes adding insulation when necessary to protect the plants against temperature extremes.
  • In summer, we ensure that plants are thoroughly watered before they leave our nursery. Occasionally, we may need to ship plants bare-rooted, particularly when they cannot be comfortably re-potted into smaller packaging for shipping. We will always discuss this with you in advance if your plant needs to be shipped in this manner.
  • It's important to note that shipping can be a stressful experience for plants, often due to spending several days in a dark, confined space. While most plants withstand this with little to no stress, some may experience leaf drop. However, they generally recover quickly with some additional care, including proper watering and gradual reintroduction to light after arrival.
