These trained bamboo plants are tricky, because they require that you continually train them to a post when growth is going to keep that shape. When allowed to grow normally, of course they grow straight, and fast. You can trim that top growth off without harming the overall plant (use the 1/3 rule, of course), but you'll likely get multiple offshoots where you do the cutting because the trunk of bamboo is fibrous, and will regenerate new leaves from cuts, that will eventually turn into shoots over time. You might even get some new shoots from the soil line after spurring new growth after cutting, which is a positive or negative depending on how you see it.
If you wish to keep it small, just set a reminder to trim it every so often and keep the new growth to where you'd like it. Treat it like a Bonsai.
I’m guessing there was lots of failures, obvs sharing them isn’t all that interesting to most people, and unfortunately being candid can also back fire. Some people can’t understand the concept of “failure” especially when some plants only have a germination rate of 10% and he also isn’t growing them in their local habitat either, which makes it harder.
Kudos to him though, I’ve wanted to mess around with more plants in aeroponics myself. Maybe even make a pipe wall with some ornamental plants in it.
Our house came with a bed of Lilly of the valley and mint. Thankfully it's surrounded by cement, although both try growing in the expansion joints. It smells great at various points throughout the year but we've given up on getting rid of it. Infinite mojitos though.
I think I remember something about other insects that may get triggered to attack when one is killed. (I am not really sure though. It might have to be a stingy-type insect, but I couldn't Google anything about it.)
Bees do that. I once helped a bee keeper by holding a ladder so he could get the runaway queen out of a tree. There were so many bees, but i kept calm so they leave me alone. One of them stung me in my baseball cap and suddenly i had to book it, because all the vees were suddenly after me. I got stung like 5 times or so. I only later found the stinger and some bee ass in my hat later.
Also fun fact, getting stung in the eyelid is very uncool.
I think it's BS. Logic would say it's BS because of evolutionary purposes of pheromones, which would made in glands, and in almost any other case used for attracting LIVE mates. If you suddenly smashed one, then the worry is you're busting their pheromone sac or whatever and attracting more? Specious.
I'm suspicious haha. I looked it up anyway and can't find any proof of that, only the negative.
Check the roots, you might have pests eating the roots. Could also be too much watering. Hard to say from photos but I definitely think something is wrong below the surface
When it shows signs of over watering, they only need about an inch a week after being established. When they are new or transplanted water daily for a week, than give it an inch of water a week. If it rains an inch, you’re done for week unless it’s stupid dry and starts showing signs of needing water (obviously).
I doubt it's over watering, due to the fact the others look healthy enough. Dig up the root ball of that one, look for pests in there would be my first step to diagnosing.
Every day is probably too much, unless you're in a dry area and they're very well drained. I'd describe watering as saturating, not flooding, and let it dry to the roots, not just the surface, before watering again. Dry, but not completely moistureless bone dry
Also, on hot sunny days, water in the evening or early morning, else you'll just lose a lot of water to sun evaporation.
Since you tried nutrition I would suspect injury to the plant has allowed some kind of infection in. I would try trimming away all of the diseased or damaged plant matter and then applying a copper fungicide. I've had tomatoes with vines split fully in two and the plant stayed productive and vibrant once it got far enough from the damage and new growth was happening.
This is not a criticism , but they seem crowded, we all work with the space we have. Also, have you planted tomatoes in that spot before? That can cause issues too.
Don't over water, let them dry out a bit, remove the dying plants asap, use a copper fungicide, and next year replace a lot of the soil if you have to plant in the same spot. If you can, rotate your crops every year.
At first I thought it was one of the "wilts". These are soil-borne pathogens that attack the plants roots. The causitive organism could be verticillium, fusarium, or phytophera. In small plants pythium or rhyzoctonia can kill them. There is also bacterial wilt that causes the rapid decline of the plants.
Then I zoomed in and took a closer look at the plant. I suspect it's nitrogen deficiency. It could be caused by over-watering (denitrification and leaching nitrate out of the soil profile). However I suspect you didn't have enough to start with.
The tomato tone looks to be a 3-4-6 fertilizer. To put it simply, it's a stupid fertilizer blend. Plants need nutrients with a ratio of around 3:1:2. So you need 3x+ more nitrogen in that blend.
Once the plant sets fruit, it starts to dedicate nitrogen into the fruit/seeds. In a shortage situation it moves them from the lower leaves (they turn yellow and die).
