Your female tree may be lonely and needs a partner for reproduction. 

This just in, from my botany guru:

Thanks for the tips and research. Our soil has come back after 8 years of no spray, but more inoculation is a good idea. Seems very likely there is a set of organisms that are copasetic with chestnuts.   

Yes, definitely there will be species- and site- specific as well as general beneficial soil biology in action. But it requires more than no-spray to manage and cultivate.  Inoculation with native soil is good if possible, and insuring that the microbes have conditions condusive to flourish. Which includes soil moisture, organic matter content, aeration - no compaction or pavement.  To go all out, consider engineered fungal-dominant compost and compost extract and tea.  This plus multiple mixed species cover cropping is the state of the art in the emerging science of complexity and organic soil building.  See "Soil Food Web" info and other resources listed in the Regenerative Ag discussion on this forum.

TV farming member Evolare ( FB vendor Best Garden State)  recently informed me that he has a cover crop expert developing seed mixes for tropical crops and conditions. This is a huge development for organic farmers here who are in touch with the emerging regen ag approach. They are also now marketing a high quality vermicompost, as well as complete organic fertilizers and other organic grower supplies.

'Jack compost' you know, from Natural Agriculture in Mae Taeng. The batch I bought last week was not as thoroughly decomposed as before, a lot of course solid wood fragment content. Check it to see what you are getting. 

Finding The Mother Tree is a fascinating new book just out this year from PhD forest ecologist Suzanne Simard. 

Good question. I didn't know the answer so I've been looking.  The genus Stericula is said to have unisexual as well as bisexual flowers, and can be monoecious or dioecious. This particular species, S. monosperma, is listed as having unisexual flowers, but I don't know botany details that well and I don't know if that means that your tree has only female flowers. I can't find a reference to whether its monoecious (self pollinating) or dioecious.  I'm going to ask a couple of botany expert contacts. 

Keep in mind that pollination is not the only factor for quanity and quality of seed production.  Nutrition through soil fertility and the extensive mycorrhizal fungal networks that form in association with roots in the natural environment can make a big difference.  If its a single, out-sourced, planted tree in an altered, disturbed, nutrient-depleted soil environment, it may be at a disadvantage, even with adequate pollination. 

When you 'go into the woods to pick some', take a bag and a trowel and bring back some native soil and root fragments to spread around your tree for inoculation of the beneficial biology that goes along with it.  Spread compost and wood chips mulch on top of that to create a living soil environment as best possible.

FYI, Khao Tom is not the same as Jok.

 

Yes, you're right, there are some big differences and there are variations, depending on whose terms are used and who is cooking. I would value your opinion and that of others.  

From my experience of common Thai use is that jok (Cantonese word for rice porridge, Congee term is Portugese origin I believe) is cooked with cracked rice, and Khao Tom with whole rice.  Thai jok or khao tom usually is cooked with plain water, although the better tasting and possibly heathier versions use a rich soup stock. Jok has ingredients cooked into the mix, and khao tom I believe traditionally the ingredients are served as condiments on the side. 

When I studied TCM and Chinese dietary medicine, we leaned to use congee with various ingredients as medicine for specific health conditions, like a home cooking version of herbal medicine. Whole rice was used with chicken, fish or pork bone-ginger soup stock, and the ingredients cooked into the porridge. Ratio was 8:1 water to rice or more and cooking time was extended until the rice was as smooth as Thai jok. Medicinal effects were oriented to correcting body heat and cold conditions, dry and damp, yin and yang balance and 5 elements. 

One reason that I prefer the whole rice kernal preparation, is that cracked rice although it cooks easily and has the smooth texture that is desired, is more prone to oxidation and loss of nutrients and vitality, depending on length and method of storage and preparation. 

I have to check if she is still there or not, I just moved back, but best Khao Tom I used to get a few years ago, was at a cart in the evenings on the road in front of Raumchok Market. (1001 Phrao MaeJo Rd at middle ring road, next to Meechok Plaza). 

Please share location details of the two you know about. Don

Thank God, NO.

IMPORTANT INFORMATION

Miracle-Gro Evergreen Natural 4 in 1 Lawn Food will not work on mature weeds already present in the lawn, it will only prevent the growth of new weeds.

Since Miracle-Gro Evergreen Natural 4 in 1 Lawn Food impacts the establishment of new weeds, the effects may not be visible the first 3 months after spreading.

Avoid mowing the lawn 2-3 days before and after treatment. Do not use the first 4 mowings after treatment for mulching. They will be safe to use after being thoroughly composted for 6 months.

Staining

Apply this product very carefully as it will cause brown stains on any surface it comes into contact with, e.g., clothing, tarmac drives, paving, decking and kitchen floors. Note this list is not exhaustive. Do not walk on the treated area and keep children and pets away from the area until the product is thoroughly watered in, the granules have dissolved completely and the grass is dry; otherwise, it will stick to shoes or pets’ feet and be spread outside the treated area. Clean up any spillages.

Miracle-Gro EverGreen Natural 4 in 1 can be used around trees in the lawn, but avoid contact with foliage. Avoid drift onto nearby flowers, shrubs, fruit trees, vegetables, ponds or streams.

Cautions

Do not apply to lawns less than 6 months old. Do not apply during prolonged dry periods (drought), frosty weather or when temperatures exceed 25°C.

Yes, glyphosate would be my product of choice but with considerations. It can and will translocate thought root grafts into nearby trees, so use with caution.  And no need to drill holes. re-cut the stump surface if possible and paint or spray the outer circumference (cambium growing layer and sapwood) with a 20-25% active ingredient solution (48% glyphosate diluted with equal part water).  Don't waste drilling or spraying the interior inactive heartwood. Only the outer circumference can absorb and translocate the chemistry. 

 

If there is no access to re-cut the stump, then spray the foliage that is sprouting from the stump. This may take repeated applications until the stump no longer resprouts. 

 

If you can't get to the stump to spray it all the way around, then maybe reach under the deck with a pole saw and cut off the sprouts. Repeat this until it no longer re-sprouts.  

 

If none of this is possible due to tight access restrictions, then follow the other advisors in removing the deck surface for access. 

FYI, worth the mention, there is another chemical herbicide that is highly effective and doesn't require a fresh cut for absorption. But I haven't seen it in Thailand.   In managing a highly researched cut-stump treatment program for a large public utilities company, besides the glyphosate, I have also used Garlon 4 Ultra (Triclopyr-ester).  This can be sprayed on the bark of the lower stump and root collar for penetration through the bark to kill the growing layer, best with a surfactant like MSO methylated seed oil or diesel oil (yes smelly). 

The use of herbicides in this type of treatment should not include application to the soil surface, so environmental contamination is minimal. But be aware that the active ingredients as well as the surfactants can volitalize into a gaseous drift and contaminate nearby plantings.

BTW.  Be aware.  A saber saw is a powerful tool.  It is not some toy electric screwdriver.  When you are using it be careful.  Not only about cutting off your thumb or something.  If the blade is pinched all the power going to the blade quickly transfers to your hand/arm and jerks it with the same power.  If your fingers are exposed to, say, a branch or a bit of a cement wall or whatever they could be badly scraped or crushed.  Or you could be thrown off balance and fall off a ladder.  All those pictures illustrating smiling people trimming trees with one hand are misleading.  This is a tool that must be treated with respect.

And what about the danger to the poor trees.  As a tree surgeon, people talking about crude pruning with sawzalls and bow saws makes me cringe. I realize that most people think of trees and property and not as living things.  Demolition is one thing, but if anyone cares, there are best managment practices for pruning. Chose a sharp tri-cut blade pruning saw and cut just outside the branch collar, to promote wound closure and to minimize damage and fungal infection. 

I've nothing against the bananas, I planted some Gluai Nam Wa offshoots from our friend's farm, at our home yesterday .  Mosquitoes and knats? I didn't think about it but I'll deal with it when the time comes, sanitation, botanical insect repellent is easy enough for a small planting.  

But when I saw the post about having 1 rai and not knowing what to do with it, I remembered this old post that I saved, from Tim, CNXPAT - Growing Makua (attached).  I wish there were more posts like this, on this fading forum. 

I used this information for a garden planting in Santa Cruz California. My wife Bee brought Thai makua seeds to the US, (she can't live without her geng keow wan,  and the Thai restaurants weren't quite up to her green curry standards).  We planted a couple of rows. 

The heads up about susceptibility to fungal pathogens was useful, but I converted the whole concept of soil fertility and pest/disease control to a 'high nutrient density', organic methods and materials approach, with soil testing, Rx mineral and biological amendments, and preventive botanicals and biologicals.  We had healthy, pest and disease free makua and other veggies, and lots of good geng keow wan.

I hope flights will be an option early Nov and will of course track the situation closely.

 

Just trying to establish what the current rules / guidelines are for leaving ASQ Bangkok and travelling to CM. Hoping to avoid the need for doing quarantine twice - even self isolation in CM after ASQ 15 days doesn’t appeal.

I was released from Bangkok ASQ on July 23rd.  My Thai step-daughter and husband, Samut Prakan residents (license plates) picked me up at the hotel and drove me to Chiang Mai. There were two or three standard illegal immigrant checkpoints along the way but we were waved through. At the primary Chiang Mai Covid checkpoint on the 11 SuperHwy, we had to stop and show paperwork.  (It appeared that we could have exited at the 121 ring road or other and avoided it, but we chose to do the right thing and comply).

My daughter who is quite savvy on all things medical and technical had pre-registered our trip online and had everything together for the three of us. We were checked and ordered to proceed to Arcade bus station where there was a Covid screening/testing facility set up. Due to my US vaccination and ASQ documents, I didn't even have to get out of the car.  She and husband had current negative Covid test results and were cleared after filling out forms. 

The day after arriving at home in Sansai, the pooyai baan and wife, who are quite friendly with my wife, came around to document my paperwork and request that I stay at home for two weeks. There was no formal order or further follow up. 

That was almost a month ago, but I hope that helps, Don

The short answer is, I haven't seen Milky Spore or nematodes offered for sale in Thailand, even at an ag shop I use near MaeJo University, which carries more organic program materials than most, but that doesn't mean they are not out there, search the online retailers.

Try "green maskaradine fungus"  Metarhizium anisopliae, for biological control of the grubs.  

The longer answer, excuse my preaching, is try to look at the bigger picture and how to promote condtions that will naturally control pests and build resistance.  A biologically active soil already has a multitude of beneficial bacteria and fungi, nematodes, micro arthropods, etc that keep things in balance. Read "Teaming With Microbes" or see the wealth of YouTube videos, especially Soil-Food-Web subject.  

Raised beds don't always have the benefit of established soil biology, depending on what kind of soil or engineered substrate that you have used as a growing medium.  Raised bed and container growers often use sterile medium due to poor drainage with native clayey soils, and fear of soil borne pathogens, but in so doing they set up a situation where you have to introduce/inoculate with beneficials, or suffer the consequences of trying to keep up with the deficiencies and imblances with guess work, always searching for a curative product.  Soil-less, clay-deficient substrates usually do not have good nutrient holding capacity and often drain too fast and leach nutrients.  High NPK chemical fertilizers are harmful to the soil biology.

Is this forum still active? Good question. Format then name changes seem to have diminished interest from long term posters like me. Definitely a very slow traffic flow. 

 

Yes, let's keep it active!  In my opinion this is one of the most important discussions that has taken place here and I'm grateful to SBF for the inspiration and the links and to others for their contributions. 

I was recently released from solitary confinement, (also known as ASQ for two weeks in a Bangkok hotel).  I prepared myself mentally for the experience and brought reading material and YouTube video links, as well as an online solo exercise program.  It wasn't too bad, especially since I made good use of the time.  It gave me a chance to dig in to this material in more depth than I  had previously and its a mind blower.  

There is information being presented by Dr Christine Jones, Dr Elaine Ingham, Gabe Brown, Graeme Sait and others that SBF provided links for, that could be a game changer for climate change issues, regenerating depleted and misused soils, and potential profitability for farmers. 

One of SBFs links led me to some info in Thai about a German/Thai cooperative. Anybody had any direct experience with GIZ projects?

Trust me, there are. Few of 40m plus, no hard wood though. Mostly Mango trees, Lam Yai, Litchi and Coconut palms. Plus a few Makham and Baelfruit. Bananas and smaller trees which I do not know. The picture shows a small angle of the front side towards the roads.

 

I definitely have lots of cicadas. They make a hellish noise during the summer season. And they build chimneys too, just not THESE chimneys.

Am convinced now it is the crayfish. Installed two cages with bait, lets see what will happen. Ordered 25kg Lye and heavy duty rubber gloves on Lazada too (well, my daughter did.)

 

 

Lye or lime?  If lye, you may not need to worry about mowing the grass any more. If lime, be sure that a soil pH test indicates acidity, or you may be driving the alkalinity too high.  In either case, I don't think either is appropriate for the cicada control. 

I'm not sure about details of the cicada life cycle here, but we just had a giant cicada turn up in our yard here in Chiang Mai, so that indicates it is the season for emergence of adults. If that is what is happening in your yard, then the timing may be past for control of the nymphs in the soil.  So it may be useless and a waste to apply harsh chemical insecticides like Sevin (a carbamate that really should be avoided for the toxicity issues, and is not necessary) or Reclaim IT (bifenthrin, a potent pyrethoid, less toxic but not without some concerns, effective for turf grubs but hell on beneficial soil biology). 

As for the cicada turrets, I'm not a golfer but maybe a 9-iron would give you the heavy metal to level the field and be able to pick up the clods, and save your mower blades. 

As for the cicada concert, my daughter says she prefers her headphones and BlackPink.

If you have a local fertilizer store I would go show them and get their advice.

Poor suggestion in my opinion, local garden shops will likely recommend a high NPK chemical fertilizer and or chemical fungicide, which will exacerbate the susceptibility to the common plumeria problems like rust-fungus infection and mealybugs pest infestation, etc. 

Use a new generation COF (complete organic fertilizer) like the "bokashi" from Organic Totto, or the excellent new line of organics from Best Garden State on Facebook. There is a revolution going on with emerging science and profound positive experiences with organic and regenerative agricultural and horticultural methods and materials. 

Other suggestions here about the tiny pot, well drained soil etc are right-on in my opinion.  Plant health care is primarily all about species/variety/cultivar selection and placement with compatible plantings, good growing conditions, soil and water management.  With the right conditions and management, plants have remarkable capacity to fullfil their genetic potential and for resistance to pests and diseases. 

TV member Seajae is a plumeria expert and collector. Maybe he will comment. 

Yes, comfrey grows well in Thailand. I have grown it in Chiang Mai from an expat farmer friend's gift of some fresh root material.  I've never seen it for sale.  Some countries have banned it due to reports of toxicity. I don't think thats the case with Thailand, it is more of a matter of unfamiliarity and lack of demand. Thai farmers that I know have never seen it and its not part of Thai, Ayurvedic or Chinese traditonal medicine as far as I know. 

In the 1970s - 80s as an active tree worker and martial arts enthusiast, I took a beating almost every day and sought out traditional and folk herbal remedies to deal with trauma and pain and to keep-on keeping-on.  I made poltices with crushed comfrey leaves for external compresses, and consumed capsules of powdered root. I liked the healing effects I experienced, but I was doing a lot of other self help herbal and chi kung practices at the same time. I read reports of remarkable healing experiences and regeneration of burned and abraded skin, and of course the traditional use for acceleration of broken bone healing. 

I did not become aware of the bad press on toxicity and restrictions in use until the late 90s. I don't know when this all came out. I wasn't sure about it because the negative side effects were not part of my experience, but I discontinued using it as medicine.

I still grew it for use it for composting material, its great for bulk green/nitrogen component in "hot composting", and it grows like a weed wherever you plant a piece of a root and water it.  I've read some opinions that it shouldn't even be used in compost, but I have a hard time buying that based on personal experience.  I haven't seen the science behind the fears. Please let me know if you have. 

If you or anyone else finds some, i would appreciate a tip on where to find a plant or a piece of fresh root.  I'm just back in Chiang Mai and starting a small home veggie garden and composting at our new home. (On a mission to transform some nasty mooban fill dirt into a patch of fertile soil to grow some organic, nutrient-dense food items.)

My challenge is that our fruit tree area was created to concentrate abd minimize the space used so as to emphasize flowering species elsewhere, so we need to either take out half the fruit trees or prune to keep smaller. One of our friends has the biggest lychee tree I’ve ever seen and it is a real beauty. Last year it had abundant fruit and this year very little. I’ll take your advice to lightly prune the lychees for now, and see what next year brings.

Take out trees or prune to keep smaller, this is a hard choice. But I would vote for the removals, to make adequate space for the remaining trees to grow into maturity.  I have multiple reasons for this opinion, besides my love of natural form and beauty of trees, and abhorrence of over-pruning and the distorted, excessive growth reactions.  Also, there is the pysiological stress created by over-pruning and the excessive growth that results when the trees have to refoliate and use stored sugars. And it increases your pruning frequency cycle. 

From a paper on lychee growing:   "heavy pruning should be avoided as it induces profuse vegetative growth instead of floral growth."

Your property is kind of borderline for good lychee fruiting isn't it?  They need a chill factor.  I know most of the orchards I've seen are at higher elevations. There are various varieties and that may make a difference. 

The CMU Site B orchard on Doi Pui is just below the summit at about 1200m.
