August is an exhausting month in our garden, and on many farms – so much to harvest (successful farming!), so many weeds growing, lots of irrigation to manage, and we’re not done with planting for another month (and then there’s still garlic!). We are ready for some crops to be finished, so we have more time for other things. Annually at this time, we engage in a “how many watermelons do we need anyway?” conversation. We have passed 400. Our goal is usually 600-800. In 2012 our peak day of watermelon harvest was August 9 with 99 melons.This year our peak day was August 6 with 127.

In 2014 we decided to stop harvesting watermelons for eating on September 1, when we reached 531. We processed more for seeds for sale after that. Our Crimson Sweet Virginia Select watermelons are huge and delicious. This summer has not been so hot. We haven’t been eating 22 per day as we do in really hot summers. Maybe we can stop soon? Then we can plant a cover crop of winter rye, crimson clover and Austrian winter peas with plenty of time to grow before next year’s sweet corn crop.

As I said, this summer has not been so hot, and ironically this is the third year of our eggplant variety trials, looking for good heat-resistant variety that compares well with Nadia, which we like a lot, but found wanting in the hot summer of 2012. In 2013 we simply counted the yield per plant and compared 4 varieties.

In 2014 we weighed the fruits too, to find out if some varieties had smaller fruits. We found that all the varieties we grew have similar sized fruits. Nadia gave the best yield per plant, Epic was second, Traviata third, with Florida Highbush a poor fourth. For 2015 we added a fifth variety, Florida Market, (like Florida Highbush, this is also open-pollinated.).

So far this year, Epic is winning, at 4.1 fruits and 3.4 pounds per plant, with an average of 0.84 pounds per fruit. Traviata is running second, at 3.1 fruits and 2.4 pounds per plant (average of 0.79 pounds per fruit). Nadia is third, at 2.3 fruits and 1.8 pounds per plant (average 0.75 pounds per eggplant). Florida Highbush (yes, it is a tall plant!) is beating Nadia on tonnage (2.1 pounds/plant) but losing on size (in other words, more smaller eggplant). Florida Market is trailing, with many days providing no harvest. I’ll do a full report in another month or so, when we decide to stop harvesting.

We have at last finished filling the gaps in our endless rows of cabbage and broccoli. We started the transplanting 4 weeks ago. We have been doing this work 7-8.30 pm, and it has seemed especially grueling, as we really needed more help. Lacking enough workers, the job went on and on. We also got into a spiral of shorter daylight by starting late and needing to continue later in the year. And the over-large plants were harder to plant and less likely to do well. And having so many shifts with the irrigation running led to over-watering especially at the low end of the field. And the weeds grew bigger . . . . More people and fewer weeks of transplanting would lead to greater success and more happiness.

We did a brief review of the process, in hopes of making enough changes so that next year the job will be less of an endurance test.Here’s our ideas so far:

Adjust our crop rotation to avoid the need to plant the fall cabbage and broccoli after the spring potatoes (a very fast turnaround with no slack for things going wrong).
Reduce the number of broccoli plants.
Increase the number of crew each evening. Stay on top of scheduling people.
Leave better information for the crew the next day. This might only save a small amount of time, but it would reduce stress. We use maps and various highlighters to show what’s done.
Avoid over-watering.
When it’s time to do gap-filling, assign each worker a row, and have them fill gaps in one row as they find them, watering in as they progress. Avoid any temptation to look and count gaps first – it wastes time!
No, we really don’t want to do this work in the late afternoons. We’ll stick with evenings.

Last December I wrote about trying new eggplant varieties

After my experience in the hot summer of 2012 with our Nadia eggplant refusing to set fruit in the heat, I started looking for heat-tolerant varieties. We like large, classic purple-black Italian types. For a while in early summer 2012 the Nadia didn’t grow at all – no new flowers, never mind new fruit. I looked at growing some combination of Nadia (67d, good set in cool conditions) with some of

Epic 61-64d (early and huge!), from Osborne, Stokes. Recommended in Florida and Texas.

Night Shadow 68d, (size claims vary from “similar to Epic” to “smaller”), Osborne, Stokes, Siegers.

Traviata (variously recorded as 55-60d, 70d and 80d), small but good flavor. Osborne, Johnnys, High Mowing. Recommended in Florida.

Irene (mid-early). Large, shiny purple, traditional-shaped fruit 5″ x 6-7″. Great flavor, big plant, productive. Seeds from Italy.

Classic 76d, heavy yields, high quality, does not perform well in cool conditions. Harris. Recommended in Florida and Texas.

Santana 80d, large, continuous setting. Siegers. Recommended in Florida.

These are all hybrids, but I also found a couple of promising -sounding OPs:

Florida High Bush eggplant from Seed Savers Exchange

Florida High Bush 76-85d, reliable, large fruit, drought and disease resistant. Seed Savers Exchange, Cherrygal/Sustainable Seed Co. Recommended in Florida and Texas.

Florida Market 80-85d, large, excellent for the South, not for the Northeast. Baker Creek. Recommended in Florida and Texas.

If anyone has any comparisons of two or more of these, I’d love to hear more. (Also if you have others of purple-black, classic shape to recommend.) I can see the sense of planting several varieties, including a fast-maturing one, followed by more heat-tolerant (but slower) ones.

This year we tried three new varieties. Generally we like to have some reliable workhorses that we know well, and trial a few new things, especially if we hear our favorite varieties are no longer available. So alongside Nadia, we trialed: Florida Highbush is open-pollinated, from the Seed Savers Exchange. Epic and Traviata are hybrids from Osborne Seeds.

Ironically, this summer was not hot. One of the coolest we’ve had in a long time. We just did a final harvest in preparation for our first frost, which happened Sunday night October 20/21, and I crunched the numbers. Our record-keeping was a bit spotty, some days we didn’t write anything down. But the relative yields should be about right.

We planted 38 Nadia, 10 Florida Highbush, 10 Traviata and 12 Epic. Harvests started on July 25, later than our usual July 10, because of the cool weather. We harvested three times a week until 10/17. I was surprised how few fruit each plant provided – about 6. We only recorded the number of each variety harvested each time. I started out noting size and number of cull fruit, but that didn’t last long! Initially, Nadia was providing by far the largest fruit, with Florida Highbush the smallest. Traviata doesn’t claim to be big. In the first week of harvests, Nadia produced most per plant, but this leveled off pretty soon.

Final figures were 7.3 fruits/bush for Traviata, 6.3 for Florida Highbush, 6.1 for Nadia, and only 4.4 for Epic. In all fairness, Epic was the variety nearest the road, where the soil is drier and pebbly, and the sprinklers don’t reach so well. I wish I’d recorded weight as well as count, as Traviata’s 7.3 might not be such a good deal as it sounds.

In conclusion, I’d like to try all three varieties alongside Nadia next year, and keep records on weight as well as number of fruits from each variety. Maybe it will be hot, and I’ll learn what I originally set out to discover..

Ordering seeds! Seed Viability and Varieties New to us

I’ve been busy putting our seed orders together. As we grow so many different crops, it’s quite a time-consuming process. And I hate to buy too little and be out in the field on planting day, looking at an almost empty packet. Equally, I hate to buy too much, which either wastes money (if we throw the extra away), or else causes us to risk sowing seed that really is too old, and won’t do well. I keep a chart of how long different types of seed last:

Seed Viability

(From Sustainable Market Farming, (c) Pam Dawling, New Society Publishers, 2013)

“Opinions vary a bit about how many years seeds of different vegetables are good for. The fuller story is that storage conditions make a big difference. You can make your own decisions, weighing up the information supplied, your knowledge of how carefully you stored the seeds, the information on each packet about percentage germination when you bought it, and the economic importance to you of that particular crop. If you always transplant lettuce, as I do, you can risk one of your four varieties in that sowing coming up poorly, and just plant out more of the other three if it fails. Many seed catalogs include information about seed longevity, and so does Nancy Bubel in The Seed Starters Handbook.

www.chelseagreen Frank Tozer in The Organic Gardeners Handbook has a table including minimum, average, and maximum.

A simplified version is as follows:

Year of purchase only: Parsnips, Parsley, Salsify, and the even rarer Sea Kale, Scorzonera
2 years: Corn, Peas and Beans of all kinds, Onions, Chives, Okra, Dandelion, Martynia,
3 years: Carrots, Leeks, Asparagus, Turnips, Rutabagas
4 years: Spinach, Peppers, Chard, Pumpkins, Squash, Watermelons, Basil, Artichokes and Cardoons
5 years: most Brassicas, Beets, Tomatoes, Eggplant, Cucumbers, Muskmelons, Celery, Celeriac, Lettuce, Endive, Chicory.”

Rather than deteriorating with age, some very fresh seed has a dormancy that needs to be overcome by chilling (lettuce). Other seed contains compounds that inhibit germination. These can be flushed out by soaking in water for about an hour (beets).

Another of the challenges with seed ordering is converting between grams, ounces and seed counts. Here’s a helpful table of 1000 Seed Weight for 13 crops.

Our main seed suppliers are Fedco, Johnny’s and Southern Exposure. Fedco has great prices, especially on bulk sizes, great social and political commentary in the catalog, and no glossy pages. Johnnys has some good varieties that Fedco doesn’t, and a ton of useful information tucked away on their website. Southern Exposure is best on southern crops and heat tolerant varieties which we can’t expect seed companies in Maine to specialize in. Plus, SESE are my friends and neighbors.

This year we are trying some new varieties. Generally we like to have some reliable workhorses that we know well, and trial a few new things, especially if we hear our favorite varieties are no longer available. Last year our Nadia eggplant couldn’t cope with the heat. For a while in early summer they didn’t grow at all – no new flowers, never mind new fruit. So next year, alongside Nadia I’m trying 3 that should deal better with heat. Florida Highbush is open-pollinated, from the Seed Savers Exchange. Epic and Traviata are hybrids from Osborne Seeds.

Sugar Flash Snap Peas from Osborne Seeds

I also bought some Sugar Flash snap peas from Osborne. We have been big fans of Sugar Ann, but I’ve heard Sugar Flash is even better on flavor, yield and harvest period. We’re going to find out!

For a couple of years we really liked Frontier bulb onions as a storage variety for this climate and latitude (38N). Frontier disappeared from the catalogs of our usual suppliers and we tried Gunnison and Patterson. This year – no Gunnison! And we didn’t get a good test of Patterson last year, as we failed to weed our onions enough, after an initial enthusiastic good go at it. We were looking again at Copra, one we grew some years ago (before we found Frontier). I lucked out when I decided to see if Osborne had Gunnison, while I was shopping there. they didn’t, but they had Frontier! And then when I was shopping at Johnny’s, I found they did have some Gunnison for online sales only. So I ordered those too!

We’re also trying Sparkler bicolor sweet corn from Fedco and a drying bean I won’t name, as the seed is in short supply. And this year we’re hoping Red Express cabbage will prove to be a reliable little worker. We used to like Super Red 80, but had several years of poor results. Since then, none of the other red cabbages we tried have satisfied us in terms of size, earliness, productivity and flavor.

West Indian Gherkin Seeds (Cucumis anguiria) from Monticello

After a few years of poor pickling cucumbers, we’re going outside the box and trying West Indian Gherkins from Monticello, where they were grown by Thomas Jefferson (and some of the enslaved people, no doubt). These are not closely related to actual cucumbers, but are used similarly. I saw them growing in the Monticello garden when I was there for the Heritage Harvest Festival in September, and they are certainly robust and productive in hot humid weather. We’ll see how the pickles turn out!

My only other “impulse buy” was the Salanova Lettuce new at Johnny’s. They are 6 varieties of head lettuce designed to be used for salad mix at a single cutting. Quicker than snipping rows of baby lettuce with scissors. More fun than plain lettuce heads. They are loose heads of small leaves in various shades of green and red, and two “hairstyles”: frizzy and wavy.
