Glass House Flower Farm Tuber Policies and Guarantee

Tuber Quality: As a small business, your satisfaction is extremely important to us. We only ship firm tubers with visible eyes, but please note that tubers come in all shapes and sizes. We try to note the consistently small or thin varieties in the grower's notes so you are not surprised, but size and appearance have no impact on viability. 

Buyer Responsibility: Inspect your tubers upon receipt. If you have any issues with your order (tubers damaged in shipping, incorrect order, an eyeless escapee), you must notify us within 72 hours of receipt. 

Tubers are perishable items. Buyers are solely responsible for tubers remaining viable once received.

Glass House Flower Farm is not responsible for dahlia performance factors outside of our control, including improper storage or planting, or insect or rodent damage. We do not offer refunds for issues that arise after tubers have been in your possession for more than 3 days.

Fall Shipped Sale: We offer this sale for southern growers, experienced overwinterers, and folks who like to pre-sprout or take cuttings in early spring. If you're unfamiliar with overwintering dahlia tubers, we do not recommend purchasing dahlia tubers in the fall. We'd rather see you back at our spring sale. 

By shopping the fall shipped sale, buyers assume the risk of overwintering tubers. We will not offer replacements for fall shipped orderes in the spring for any reason. Buyers have 3 days to notify us of any issues.

Shipping: Flat rate $16 for all orders. We offer free automatic combined shipping on multiple orders - buyers must use same shipping address and payment method to qualify for free combined shipping.

Due to agriculture restrictions, we are unable to ship to Hawaii or outside of the US.

Local Pickup: Free local pickup for Michigan growers on Saturday, November 7th from 10am-2pm. If you cannot commit to picking up your order during this window, please order with shipping.

Stock Failure: We only list tubers that have visible eyes and firm bodies. If a variety in your order unexpectedly becomes unavailable before shipping, you will be notified as soon as possible. Buyers will be given the option to cancel the entire order or only the unavailable items, but you MUST respond to your notification email within 48 hours. If you do not respond, we will only refund the unavailable item(s).

Virus Practices & Policy: According to the American Dahlia Society, over 87% of dahlias are infected with one or more viruses. This is an unfortunate reality of enjoying dahlia blooms. We take the following measures to minimize the spread of viruses:

  • Cull and dispose of stock that appears weak, stunted, or shows obvious viral leaf patterns
  • Rotate and soak snips in VIrkon S solution between plants
  • Deter insects with the Brix method and by releasing successions of beneficial insects 
  • Purchase new stock as virus-tested rooting cuttings where possible

Despite these measures, due to the prevalance of dahlia viruses and ease of insect transmission, we fully expect that some of our stock is viral and are unable to offer a virus free guarantee. We do not issue refunds for stock that appears symptomatic in your field. If anything about these practices or this policy causes you discomfort, we kindly recommend that you do not purchase dahlia tubers from us.

Gall Prevention Practices and Policy:  The bacteria that cause crown gall and leafy gall infect many plants, both wild and cultivated, and can be lurking in soil, compost, and runoff. We take the following steps to minimize the spread of gall and ensure we are not shipping infected stock:

  • All tubers and cuttings are sourced from reputable growers and grown on farm a minimum of one growing season
  • We do not source from or resell tubers from wholesalers or other farms
  • Any symptomatic stock is culled and destroyed. Plants immediately adjacent are also destroyed, and plants surrounding those are quarantined for at least one full year. Any beds that see infection are not replanted for at least 2 years.
  • Shovels and snips are sanitized with bleach or Virkon S solution between plants.

In the event your tuber shows any symptoms of leafy or crown gall, please contact us. We do not issue refunds after introduction to your environment. 

Variety Guarantee: We're meticulous about labeling as part of our sanitation practices, but mistakes can happen. If we ship you the wrong tubers and a bloom isn't what you're expecting, please let us know. We can likely identify the oops for you and will offer either a refund or replacement where possible. 

Refund Policy: We offer refunds for unanticipated stock losses on our end, tubers lost or damaged in transit, and tubers that get mixed up and are not true to variety.
