The start of retail sales of seedlings depends on the spring weather conditions. They usually start two weeks after the ground has thawed (around 1 May). As container-grown seedlings can be planted throughout the vegetation period, retail sales end as late as 15 October. Up to 1,000 seedlings are dispatched on the same day. Advance notice is required. Over 1,000 seedlings are only available at a time upon advance notice. The order delivery time is up to five days, depending on the number of seedlings ordered. For amounts exceeding 2,500 seedlings, a purchase order needs to be placed.
