I think the hoar frost is when humidity and temperature align to slowly and steadily precipitate water out of the air to make frost sculptures. I have not seen it much in Florida, but relatives up north have sent me pictures.

Galatians, one more thing to consider in your lesson, whatever the dew point is the reason the temps bottom out at that temp is because of the dew wet or frozen(frost), it´s forming on surfaces pointing sky is simultaneously releasing heat which causes temps from dropping below the dew point. This is why irrigation is commonly used on convection freezes. Even at the freezing point humidity in our case, the water applied releases heat back into plant. Water applied to foliage looses about 40 kj of heat for every mol, 18ml in the cases of water then if it freezes on the plant another 6.01 kj/mol keeping the temps just above many tropical own freezing point. Sorry for doing chem teacher thing but you seem to be deepening your understanding..we use to call them teachable moments.
Heat is a little tricky to understand because many people never get past temperature. But understand how heat moves helps us as growers to make good choices on ways to protect our trees and plants.

Interestingly enough, my Dad was a teacher by profession. He used to make the calculations in BTU per gallon, which seems to be a more useful measurement for irrigation systems. He also said that there was a small benefit from the change in temperature (68 down to 32), but that the majority of the benefit came from the release of latent heat during the freezing process. I have not found him to be wrong over the years.

We have used water for freeze protection even during advective freezes successfully. Advective freezes just require more water. I think the main difference is that wind causes more evaporation and heat loss. However, a good wind break helps reduce the heat loss. Thus, the hedge h planted all the way around his property. Oddly enough, hedges have been found to be more effective than solid barriers like a wall because they break the wind up instead of allowing it to roll over. UF has a handy chart about how much water you need to apply at different temperatures and wind speeds to achieve protection if someone wants to look it up and post it.

Literature from Australia suggests that there are varying levels of susceptibility. I have seen Brewster trees with the mite--some with pretty severe infestations. It does seem to be less attractive to them, though. Sweet Heart/Florida Hak Yip seem to be the mite magnets.

I just did, you saw my invoice above. I have purchased over 200 varieties from them during my 30yrs of collecting citrus varieties.

Sam, yes, citrus is easy to graft, from one budwood stick I can get at least 2 scions for grafting so I have never had a problem with the particular variety I ordered to fail.

I just a fun hobby, some people go to Las Vegas and blow $300 in a weekend, I spend the same amount on my citrus budwood from time to time.

Budwood is a much better investment in my opinion. 😉

55
Buy a dehydrator and make fruit leather. I used up 90 lbs of Nam Doc Mai Mango that way 2 years ago. I mixed with strawberry, cranberry, pineapple, blueberry, soursop, coconut... It made great snacks for the kids.

56
At those prices, the grafts better take. I guess that is what happens when there is no competition.

On the other hand you can be thankful that you have a place to buy budwood for citrus. We no longer have that option available in Florida.

57
That is a very thorough explanation. I remember a similar talk at a blueberry growers conference years ago. They also mentioned how much water it would save waiting for the temperature to drop another degree. My Dad calculated the dollar savings and was not impressed compared to the cost of losing his whole crop because he turned the frost protection on a degree too late due to a mis-calculation. He decided that he would just turn his irrigation on at 38 and go back to bed. 🤣

When you said it was a perennial, I was thinking that it grew year round for you. Bele is supposedly more closely related to okra than Cranberry Hibiscus (Hibiscus acetoaella) and hybrids with okra have been created. Apparently they are sterile unless they undergo chromosome doubling, though. I would give Rose of Sharon a try. I got okra to take on Caesar Weed (Urena lobata) which seem more distantly related (the graft took but it did not grow strongly--I might try it again some time). I think there is a "line in the sand, though, with the true woody hibiscus shrubs like H. Rosa-sinensis (I tried a couple on Cranberry Hibiscus and they failed).

I agree with you regarding the quick bolting. The nice thing about Komatsuna is that it is semi-bienial. So, it flowers here, but it is very late in the season.

Probably on the other side of summer going into fall.

Two weeks later, it appears that most of the black has disappeared. We’ve been in a two week Santa Ana or it’s been very dry and warm and it looks like another week or so to go. Thanks for all the advice.

Sounds like sooty mold. Not sure if that is a thing in California.

We had several seedling kumquats when I was a kid. The trunks were about as big as my thumb and very thorny. The tops where the fruit was have minimal thorns. I trimmed all the thorns off the trunks of several and it did no harm. Those trees were much easier to pick.

62
Galatians, maybe it was an advective freeze event and the wind modified the air passing over swampy ground warmed the trees nearby too.

I think that is exactly what happened.

If you like Yod Fah, Purple Hon Tsai Tai is also one of my favorites and it has beautiful purple stems.

My favorite mustard green is Ho-Mi-Z, mature leaves are beautiful with dark purple and green and it's the best tasting that I have tried.  It's spicy but also has a sweet aftertaste.  One year when I was cutting back the large flowering stalks, I noticed the inside of the stalk looked tender so peeled the outer layer and found it to be one of the best tasting vegetables for stir fry and also good raw.

Best tasting collard green is an heirloom variety from North Carolina named Yellow Cabbage Collard.  Cascade Glaze collard is a unique collard green with shiny waxy coating.

My top heat tolerant lettuces:  Italienischer, Cougar Batavian, and 2 Frank Morten varieties, Jester and Icy Oak. 

With all my lettuce trials I found that I prefer growing open head lettuces that I can harvest from over a long season.  Some of the heading lettuce tasted good but it was hard to control slugs hiding inside and all that time to harvest one head wasn't worth it for me in my small home garden.  With the open head lettuce varieties, instead of just harvesting the outer leaves for salad, I harvest from the young center leaves.  As the plant matures the center leaves continue to have crisp texture and good taste even when the leaves are small and the larger outer leaves keep feeding the plant.  I also found when the lettuce starts to go to seed they will grow several feet tall and the leaves can still be harvested as good cooking greens.  They are excellent green for soups and stews. A can harvest for several months from a single lettuce plant.

Sea kale, Crambe maritima, make gourmet greens easier than belgian endive.  This is effortless to grow.  I grow them in pots, they go dormant in winter.  Before spring growth I cover the top of the pot with a black fabric pot to exclude light.  The new growth is tender white with beautiful pinkish purple leaves.  Makes a fine dining restaurant quality salad.  The leaves during the regular season that get sunlight can be used as a cooking green.

I also have greens that are my own breeding selections that I've worked on for around 15 years from crosses of my favorite brassicas.

Wonderful information! I am hoping to grow Piracicaba Broccoli next year. I would like to cross it with the Gai Lan to create a seed savers B. Oleracea for Florida. I am growing Old Tokyo Komatsuna and Toy Choy Pak Choy. I hope to make a cross between the two that will keep the eating quality of the Toy Choy without bolting so quickly. I am on my F2 generation of a lettuce hybrid between Queensland (a heat tolerant open head cos type) and Red Romaine. I am calling it Sunkiss. Everyone tells me that the flavor is excellent. I plan to select for the red/bronze color now.

I wonder how a "tree okra" would do grafted onto Bele. I have grafted okra to Cranberry Hibiscus several time with ease, but the Clemson Spineless that I was growing seems to die out after it fruits a couple times. I was hoping that grafting would solve that, but it did not. I think I need a longer lived variety like Nkruma Tenten.

I've watched frost pockets for years and know where many of them are around my yard and my Dad's property. I had never thought about fog being an indicator, though. That is a handy tip when looking at a new property or predicting frost pockets.

On a related note, a good friend used to work in a grove related business. He mentioned that one of the groves he visited frequently had a lot of topography and frequently had freeze damage on the trees down hill by the swamp. One year they had a particularly cold snap, though, and that was the only part of the grave that survived. 🤔 Sometimes strange things happen. I wonder if those trees had gone dormant from the consistently greater cold and were not as harmed as a result.

I have so much to share on this thread! 

I feel like I’ve trialed all the edible greens and most annual vegetables offered by Baker Creek, Kitazawa, Seed Savers exchange and many other regional catalogs and independent specialty growers.  I trialed all the root crops offered by Cultivariable before he stopped selling most of his offerings and most vegetables bred by Dr. Alan Kapuler (Peace Seeds).  Sand Hill Preservation Center is also a great source of heirloom seeds, root crops, and heritage poultry breeds.

I finally have narrowed down my garlic to 2 varieties after trialing over 50, including specialty varieties from all over the world, in the last decade.  I needed a variety that could produce in my cool coastal climate over a short season and have good keeping qualities. 

I have many of my own breeding projects and selections as well.  I lost my phone and a lot of photos, need to go back and see which ones were saved on my computer.

Galatians522, Gai Lan is one of my favorites and I consider Bele to be one of the best perennial greens.  I removed longevity spinach because I didn’t eat it after I started growing Bele.  Peace Seedlings (Dr Alan Alan Kapuler’s daughter’s seed company) is a great source for peas in many colors, some hypertendril.  They’ve done a lot of breeding and selection for edible podded peas.

Bele in my garden, one has burgundy new leaves and beautiful variegation, it gets some grasshopper damage.  The other has dark green mature leaves with beautiful red stems.

Janet, that is some beautiful okra and bele. I'd be interested to hear your thoughts on the greens that you grew.

Ron, the only good thing about the lychee mite is that it is pretty host specific. It should not impact your loquat trees at all. The only other species I have ever heard of being infected by the lychee mite is longan. It is closely enough related to lychee that the mite will attack it if it is near lychee. However, experts have speculated that the mite is not able to reproduce on longan. So, stand alone longans are probably safe.

67
That is based on how much your graft grows. I have seen some 2 year trees that were large enough, but it is probably wise to wait for the 3rd year.

Thank! They came out nice this year. I gave them plenty of water and fertilizer, but 0 sprays so far.  I harvested every other plant after the picture for greens. They do make a nice substitute for collard greens. I froze a bunch. Way more than we could eat.

69
I would not let them hold fruit the first year after grafting. That could potentially stunt the tree and since both have heavy fruits there is the potential for the graft to break from the weight.

70
Hopefully they live up to the hype and become available stateside.

I have started Roselle as early as January in starter plugs and direct down as late as early May. They won't bloom until they get the proper day length, so early started plants are bigger with more of a harvest. When I started them in January I only had 6 seeds. I gave 2 away and the remaining 4 plants grew to be almost 8' tall and kept me very busy. I like the starter trays if I am going early because I can keep the seed warm for good germination.

Growing cranberry hibiscus and sorrel. The leaves are tasty (both, especially cranberry), and sometimes make tea from the calyxes (sorrel).

It's quite a bit of work, but you should try candying the calyxes next year. I boil them in a simple sugar syrup until clear and then let them cool in the syrup. After that you drain and dehydrate. They come out like crasins! The syrup makes a great concentrate for tea, too.

I am growing purple sweet potatoes, moringa, Tongan spinach, Chaya, kangkong, and a few squash  varieties. I live in a dry lowlands area and have been trying different varieties of leafy greens for a few years now and have finally found some success.

Sounds like a good line up. I have been contemplating Tongan spinach (Bele) for a while.

I am going big on fruiting solanums this year (tomatoes, peppers, eggplants and various edible nightshades). My pigeon peas are all mostly in there 2nd year, and I eat them both green amd dried (I blanch and freeze thee greens if I don't eat them fresh). Its brasica season, but I still haven't had any luck with anything but mustards and collards. The rest just don't seem to grow, from seed or from starts, in ground or raised beds. I do have some kolrabi doing very well though. My carrots and magnolia peas are growing well, planting sugar peas this weekend.
In spring, in addition to my nightshades, I am also going to be putting on a good amount of Egyptian Spinach. That stuff is super tasty. Lots of squash and melons to trial this year as well.

For basically, I prefer direct seeding in October/November. I planted more about a week ago, we'll see how they do. I think anything in the bok choy family transplants well for me, but the kale/cabbage side of the family seems to can wilt and get set back unless the weather is just right. I have really been having good success with Chinese Broccoli as a collards substitute. I can save my own seed and grow as much as I want. I keep selecting for the late bloomers. I also have had good success with Komatsuna. Baker Creek sent me a packet of free seed a while back and I have been growing it ever since. It's basically an Asian turnip green. It is a semi-bienial. So, unlike bok Choy it grows for a long time before bolting.
