Tropical Fruit Discussion / Re: Moving a Guava
« on: February 21, 2024, 07:20:07 PM »
I had a ruby supreme in a 25 gallon pot full of roots with a multi trunk stem. For a while I could not control all the pests on it when in my greenhouse. In frustration,  I cut back the roots to a 5 gallon sized pot and chopped off 3/4 of the branches in an attempt to kill it. 2 years later looking better than ever and holding 19 fruits.

There was a study saying you should use repeated sprays 0.5% soap solution. If u use higher concentration it also kills off predatory mites.

Orkine, Yeah I think you are correct, I remember the graft side not looking healthy and a shoot took off like a rocket. There was massive spacing between the nodes. Thanks

I have a grafted kohala Longan that I let get out of hand. Do you think that the left side is the grafted one?

I did the acid thing. Glad I wore full safety equipment. The acid burned off the outer seed coat, smoked like crazy and turned everything black. 30min soak rinsed it off and had beautiful looking seeds. Gonna stick in the fridge for 4 monthsÖ wish me luck.

I think itís meant to recreate the digestive system of birds.i think they also need a bit of mechanical scarification like a gizzard.

So I found commercially available sulphuric acid source, and am going to give acid scarification a go. I was a synthetic chemist in a former life so I know how to handle it. Iíll post updates.

Temperate Fruit Discussion / Germinating hawthorn seeds
« on: January 26, 2024, 04:28:13 PM »
Has anybody germinated hawthorn seeds specifically succulenta and Douglassi? Acid scarification is mentioned, I was looking at using a refill of battery acid as the h2so4 source but I wasnít sure about what molarity to use. Any experience doing this?

Thatís the one I have, grows well as a bush even in a shadier area. Looks good from an aesthetic standpoint. Just needs to be more productive. Send me a message in the fall if I forget to post.

Iíd be worried about the feet being too wet, especially if it starts to lose leaves. 3 gallon to 15 is a bit of a jump.  I lost my sugar apple slowly to root rot in pots, and my reticulata looks way healthier (leaves were looking yellow) when I took it out of its plastic and put it in terracotta with a drier mix. Even my 5 foot cherimoya is in a 1 gallon tall terracotta and looks really happy.

Tropical Fruit Discussion / Re: Loquats Fruiting in Canada
« on: January 24, 2024, 06:50:46 AM »
I have both Tanaka and Novak and I don't see any difference in their flowering/fruiting cycle from my other varieties I have on the same multi-grafted tree.

Thanks for clearing that up, Kaz

I saw that you also contributed to two older threads discussing possible Spring-flowering loquats when I tried searching for more info on Tanaka and Novak.

I had mine (Christmas and Oliver as well as a seedling) all flower in the summer. They were in my tropical greenhouse all winter (>60f) and brining them outside must have triggered something (temp probably went down to 45F at night).  They all held their fruit. There must be a to trick them into flowering

Both you and Jose Spain are in agreement that loquat only flowers during the wintertime and that springtime blooms haven't occurred in either of your experiences.

A helpful user named Daytime Lobster did provide a useful link in one of the threads that links to an interesting article about possibly forcing a loquat to reflower by removing its main inflorescence. "Removal of the main inflorescence to induce reflowering of loquat" -

I moved them to a sunnier position in a raised bed this fall. Iím hoping that this and an extra year of maturity will allow more berries to set. Iíll try to update if I remember.

Tropical Fruit Discussion / Re: Banana woes (nutrient defficiency?)
« on: January 23, 2024, 11:59:02 AM »
Could it just be a seasonal nitrogen deficiency from the soil bacteria not mineralizing enough nitrogen due to cooler soil temperatures? That happens to my citrus in containers when the soil temp get down to 15C (<60F).

Tropical Fruit Discussion / Re: Interest in Jackfruit on TFF
« on: January 20, 2024, 10:44:00 AM »
I am interested, have a healthy cheena in a 15 gallon. Forum members had told me it would be impossible to fruit in normal sized container. The people I bought it from were able to set fruit on a Red morning in a 8 gallon pot but it dropped this winter without supplemental light in Canada.

It depends on your setup and what you are fertillizing with. I have large pots (7-35 gallon) with 90-95% organic material with worms centipedes etc. when I had add fresh or uncomposted fruit/veg scraps they will break down the food, the fruit flies that magically appear will break down the food as well. They are getting energy from using the carbohydrates that are left. Things like blood meal have energy stored in protein which gets turned into ammonia waste products and would be pretty toxic to most animals, it probably takes some special microbes to break that stuff down. Then I added dry alfalfa meal to pots worms didnít eat the meal initially, but after a bunch of fungus (could be unhealthy so I donít do it anymore) started to grow the worms ate the rotting bits (flies also showed up).

Iím not sure if the plant secretes carbohydrates or if dead roots are used as food source, but I think it would be important to make sure there is always something to eat if you are going organic. You will also have to inoculate your container with micro/macro organisms.

I usually add partially vermicomposted leaves & coffee grounds as a ďliving mulchĒ and fertigate with vermileachate and bokashi leachate so that there are always some undigested products and complex molecules to breakdown.

This is not a perfect system, I have problems with cholorosis if citrus if the pots are < 65F (nitrogen not getting mineralized by cold soil microbes) and I recently developed what may be a copper deficiency (resin leaking from stems) as well in some citrus.

Troph, it is possible to protect them by growing in containers with sterilized media, or do the nematodes go everywhere?

If you are going to keep it in a container and want a good yield use the largest container u can find. The roots get crazy after 1.5 year pot up from 3 gallon to 35 gallon.Here is a picture of the roots in a 35 gallon container after it set 57 bananas. Also crazy heavy feeder so compost old fruit veg scraps so you donít spend 50$ on fertilizer for 5$ of bananas.

Tropical Fruit Discussion / Re: Dry tips of mango leaves question
« on: January 08, 2024, 10:55:37 AM »
I used to always have these on my containerized mango. By watering them with rain water and feeding them with a very dilute mildly acid liquid fertilizer they have all gone away. Iím assuming it has to do with chlorine or salt stress.

Peep, thanks for the info. What did you do to fix it specifically. I read that overdoing it with the copper is worse.

Turned out pretty good for small trees, but I also never tasted a loquat before. It was pretty cloudy when the fruit was ripening, and the more shaded tree actually had some fruit that never fully ripened before it started to rot. The tree with more sun ripen faster and had more flavourful fruit, but they were different cultivars. I had ripe fruit from early November to the end of December.

It looks like I may have gummosis spontaneously discharging from my eureka lemon. Causes thoughts?

Does anyone know what they do for those fancy mangoes in Japan?

Theyíre only slightly negative, so just let it be.

Itís bad mostly because they consume plant material both dead and alive and speed up the process of breaking down the soil in container.

Most importantly, never use organic matter such as wood chips/barks or compost as your potting mix.

YouTube search Garyís best gardening videos and learned from him, heís the goat!

I think there are many ways to do things, I am sure some methods are better than others depending on the circumstances. It also depends on what you have available. When I started there was no local sources for inorganics in bulk, but there was lots of cedar& fir bark (can be purchased by the yard) and peat/sphagnum moss. That stuff breaks down very slowly. A lot of my pots are 100% organic. For my ďspecial plantsĒ I do used 1/3 perilite along with my organic mix.

Also up here bulk granular fertilizers are very expensive, so I began to use kitchen/plant waste. I have worms in all my pots they help with the nutrient cycle. Also if worms can live in the bottom then itís not anaerobic.

I have elho plastic pots which Iíve been using for 7 years which are super durable and havenít shown any hint of even cracking. On the last I even have them out in full
Sun all summer, there isnít even any discolouration. They are a little pricey but they last.

Tropical Fruit Discussion / Re: Help with my dwarf carambola
« on: December 10, 2023, 12:19:18 PM »
On a cloudy day with my double glazed glass I measure about 200umol, so during a cloudy winter day with the 200umol supplemental lights my plants are getting about the same intensity of light as yours but for shorter days. On a sunny day my umol are 1300 but days are as low as 6hr (co2 levels 600-1200). My fwang tung (first pic) often drops most of its leaves, while my sir kemgangan looks healither. Hope this helps.
