Seed Recommendation or Gardening Help:
Many times we are asked to recommend what would grow best for a person's particular area.  Although there might be some general information, we grow and live on the West Coast which may be very different from your growing conditions. You should seek this information from your local county agricultural extension agent, garden club, or local college.  They will have much more detailed and meaningful information to make your garden a success.  We have gone to great lengths to put detailed information on varieties so that you can make informed choices. Please read the information provided before emailing questions. 

Secure Server:  Yes, you can rest assured we have a secured server for all your important transactions.  Look for the little "lock" symbol in the bottom bar of your screen.

Seed Counts:  Sometimes it is hard to imagine what a gram or an oz of seed looks like till you get it.  Sometimes that looks really small!  We assure you that you are not only getting the amount advertised, but in most cases a great deal more.  The Agricultural inspector actually laughed at us when we asked if we would get in trouble by adding more than what is listed on the package (they occasionally weigh packages from time to time to make sure they are as advertised).  He said feel free!  So we do!  Weigh it yourself and you will see!  We are gardeners, after all, and spent many years looking in the package going "where is the seed"? 

Problems:  They do surface from time to time.  Please feel free to contact us if you are unhappy with our service or products.  We want to know and will make every effort to correct the problem. 

Wholesale Seed or Bulk Vegetable Seed Orders:  Please email us if you cannot find the bulk vegetable seed amount on the system or if you want to order larger wholesale seed quantities.  If you are a nursery or retail store owner and are refilling your bulk vegetable seed packet display, please make sure we have entered you into our system as a wholesale seed account.  In this way you will receive wholesale seed prices and not be charged tax by the system.

Corrections to the web:  If you find mistakes or malfunctions, please report them so that we may address them immediately.  Thanks for your help!

Q: Do you ship Internationally?

A: We do ship seeds internationally.  We also offer a phytosanitary certificate which may be required by your country's customs laws.  you can find and pay for your phytosanitary certicate at this link:

Canadian Customers prior to January 2012 were able to have shipments arrive without many issues.  As a result of changing laws though, many shipments have been stopped or rejected at the border.  As we understand it, there is no need for a phytosanitary certificate if "the net quantity of the seed for each lot (all packages of a lot added together) exceeds a small lot (500 grams or less for small seeded crop types or 54kg or less for large seeded crop types)"  For more information you can refer to the following document:

Q: How many tobacco seeds are in a seed packet?

A: There are approximately 100 or more tobacco seeds in each standard seed packet, though we do offer bulk tobacco in larger sizes.

Q: Are your seeds chemically treated?

A: We do not chemically treat our seeds and since we don't buy from out of country, the USDA does not treat our seed like many seed companies. Don't assume that if a company uses the word "heirloom" that it is grown here in the US. In fact, we get hundreds of emails from companies in China and India trying to sell us cheap chemically treated "heirloom" seed.

Q: How long will my seeds last?

A: The shelf life of the seeds varies based on the individual seeds.  Onions and Carrots have the shortest shelf life at 2 years under usual storage conditions.  If stored in a refrigerator the shelf life could be extended possibly to 4-5 years.  The other seeds vary from 3-7 years under normal conditions, allowing for much longer if kept in a refrigerator.  Freezing is problematic as the seeds, if not properly dried, can be killed through the freezing process - refrigeration is a better bet.

Seeds do need cool places for extended storage, but if you have any doubt that the seeds have any moisture, please do not freeze them - either keep them in a cool basement or garage or in your refrigerator as the freezing could possibly kill them. Adding silica gel to the container they're in will help to remove any harmful moisture from the seeds, prolonging their lives further. (Silica gel packets can be purchased on our website:

Q: Can I buy seeds to eat or make into food?

A: We are licensed to sell seed, not food for human consumption.  We do not sell anything for human consumption. The seeds are only sold for planting.

Q: Do you sell bulk or wholesale items?

A: Yes, we do sell wholesale and bulk heirloom seed. We carry heirloom flower, herb and vegetable seeds in bulk for many of the heirloom seed varieties we have. Bulk prices are found on most of the variety pages. All you need do is look for the drop down menu on each of the varieties' individual pages and find the quantity your are looking for.  For more information please visit

Q:  Are you affiliated with Monsanto(Seminis), or Syngenta (click "wholesale home garden").  Are you listed as a dealer/reseller of these companies?  

Answer:  We are not.  Click either of the above links and check for yourself what seed companies are on the list.  We get asked this question several times a day.   WE ARE ABSOLUTELY NOT AFFILIATED WITH ANY GMO COMPANY!  We are a family-owned business founded in 2009. We 100% oppose GE/GM crops and their reckless contamination of other valuable food crops and the environment.  In fact, the whole reason this company was founded was to protect non-GM seed.

Q:   Are you Certified Organic?

Answer:  Yes, we are certified organic seed handlers and the farm itself is USDA Certified Organic.   However, we do sell both conventional grown seed and organic seed to meet the needs of all of our organic heirloom seeds for sale vegetable seed catalogcustomers.

Question:  How are you different from other organic heirloom seed companies?

Answer:  First off, it is important to note that there are VERY few Organic + Heirloom seed companies out there, meaning most of the seed companies out there sell heirloom vegetable seeds, but very few sell Certified Organic Heirloom Seeds.  Click here to read about the difference.   However, to further answer the question, one of the most important distinctions about Sustainable Seed Company is that we actually sustainably farm and grow many of our own organic heirloom seeds right here on our certified organic farm.  Very few seed companies do this -- in fact, none to our knowledge use green technology like our wind turbine and solar panels that we use to sustain our farm's energy needs.  We are a company with one foot in the past and our eye on the future.  We remember the lessons our grandparents taught us and embrace the green technology of tomorrow for those that follow in our footsteps.  We want to leave the world a cleaner and greener place than how we found it.  Yes, you CAN produce food and seed without the use of Genetically Engineered crops, toxic pesticides and destructive herbicides.  We are changing the world one seed at a time!

Q:  What is the best way to contact you?

Answer:  Through our support center.  This program allows us to assign your particular problem or question immediately to the right person.  Since we are an internet-based company, we check our emails many times during the day.  This also allows us to track the question and resolve any issues on the whole quickly.  90% of the time you will get a much faster email response than you will get a phone response. 

Q:  Don't you think you are loosing a great deal of business by not printing a paper catalog?

Answer:  By far this is the most heated and talked about decision we have made as a company.  We knew taking a stance against paper catalogs was not going to to be easy, as people have been doing it this way for over 175 years.   However, any time someone does a "first," it can be very controversial.  Our environmental reasons are clearly lined out on our page as to why we do not print a catalog.  There are other reasons as well that are not as impactful as our green ones, but are still important and may appeal to people's practical side instead of the green fuzzy side.  For example, having an on-line catalog allows us to update quantities on rare seeds immediately and cuts costs.  We rarely have to spend the time calling customers and offering substitutions or refund checks, which we then have to pay someone to write and send. Nor do we have to pay someone full-time to open envelopes, interpret people's handwriting on orders, and hand-process them into the system.  This saves us money and resources, not to mention what we save on printing and mailing costs.   We decided we would rather pass these savings on to our customers, so that we can keep offering our seed packets at our very low rates.
