Update Nov 6, 2019: Caught up on orders again today. I imagine this will be the last batch headed east of the Rockies until spring. It is getting cold, so orders from here on out will be queuing up for spring shipment.
Update Oct 31st, 2019: Happy Halloween! Several things were added to the store this week. We have a couple of mashua varieties, oca tubers from this year’s seedling crop, a dwarf Jerusalem artichoke, fresh sea kale seed, and a few other things. Tomorrow will be the mailing day this week, so any orders placed through today will ship tomorrow (weather permitting).
Update Oct 16th, 2019: Caught up on orders again, so if you had an open order, it will be in the mail tomorrow. We’re having a very rainy week, so outdoor work is at a standstill. I anticipate starting some yacon harvesting when that lets up, so if you want to see new yacon varieties, make sure to join our Facebook group. I will probably begin harvesting oca around the first week of November, which should also be quite exciting, as this is the largest crop of seedlings that I have ever grown.
Update Oct 4, 2019: I took advantage of a rain break to get all the orders out the door (with the exception of those that are still on preorder). All true potato seeds are now in stock for the year! I don’t think I have ever managed that this early before.
Update Sep 19, 2019: Much of this year’s crop of true potato seeds (TPS) is now available. Some are still on preorder, which means that I have harvested the berries, but some of them will still require another month or two to process. In addition to the mixes, I have added both open populated single variety TPS and controlled crosses this year. This is an experiment. If they sell well, I’ll add more and if not, I’ll stick to the mixes.
Update Aug 18, 2019: Some potato varieties are now available for immediate shipment. If you want to get an early start next year, you can order now and store them yourself. I recommend storing seed potatoes in a perforated plastic bag in the refrigerator. They will easily last more than six months that way.
Update July 28, 2019: I have good news on several fronts. Testing of the few varieties that we grew in sale quantity this year has gone without any surprises, which means that we will have some varieties for sale this fall. It will still be much reduced, but something is better than nothing. We will at least have several varieties of potato (including Rozette), several varieties of mashua, and hopefully at least two varieties of ulluco. The picture with oca and yacon still remains uncertain as I have learned about new viruses that might exist in those crops for which we have not tested in the past. I will have to outsource that testing and probably won’t have the results until after harvest. I don’t really anticipate that we will find anything new, but better safe than sorry. On the seed side, I expect that we will have a much greater variety of true potato seeds and dahlia seeds than in the past and we should have a reasonable harvest of oca seeds and wild potato seeds as well.
Cultivariable is going through a transition from the practice of growing our roots and tubers repeatedly in the field to a process where we start from tissue cultures, followed by screenhouse multiplication, and only a single generation in the field. This process will better control diseases in the crops that we offer, yielding a higher quality product. A number of new diseases have been discovered in the Andean tuber crops recently and it is better to stop and ensure that things are as disease free as possible now than to continue on breeding with varieties in a questionable state of health. This transition is costly and time consuming and will probably not be complete any sooner than 2021. As a consequence, many varieties will not be available for the foreseeable future. Many of the heirloom varieties will probably not be back at all. They don’t perform as well as my selections and they are much more likely to be carrying unknown viruses, so the most cost effective strategy in most cases is to simply stop growing them.
In the future, I will be focusing my efforts a bit more narrowly. The majority of my work will continue to be with mashua, oca, potato, ulluco, and yacon. I will continue to grow the other Andean root and tuber crops, but I don’t anticipate offering them in the catalog until I have varieties that represent significant progress. I continue to do quite a bit of work with sea kale, dahlia, and skirret, so those should appear in the catalog every year. The other minor crops that we have offered in the past may only appear every other year.
The good news is that, by specializing a little more, I expect to have greater capacity for the big five crops, so, once we get through this transition, we should have more varieties than ever of mashua, oca, potato, ulluco, and yacon. This is particularly true with potatoes. I have a lot of great varieties, but disease management is so difficult with potatoes that I have been reluctant to multiply them for sale in the past. We now should be able to offer much more potato diversity with greater confidence.
So, stick with us. It could be a long wait for some of your favorite varieties to return, but they will be back along with a lot of new ones as well.
I have had several people ask if they should continue to grow the heirloom varieties. I am somewhat ambivalent on this subject, due largely to my own ignorance. I am taking the conservative approach and trying to eliminate anything suspicious. If you want advice, then I recommend being conservative. If a variety isn’t currently listed for sale in our catalog, then I don’t recommend growing it. There is no heirloom variety that I trust, not because I know that they are infected, but because I don’t know if they are clean. All of these crops have been grown continuously in the US since at least the 1970s and longer than that in some cases. Some, like yacon, are grown on a relatively large scale (compared to something like ulluco or mashua which are probably grown exclusively at back-yard scale). I have no reason to think that they were not carrying diseases that entire time. Obviously, the world hasn’t ended. Probably, that is because they are grown on such small scale, don’t come into contact with other crops, and, possibly, any diseases that they carry don’t transmit very easily. However, these crops are also experiencing a little boom in popularity, which means that the exposure is increasing. The absolute safest thing that you could do is eat up whatever you grow, don’t plant again, and wait for us to release new, verified clean varieties. I don’t have all the answers, unfortunately; I’m learning as I go.
