Yes excited, as in 4 days I'm heading for vacation with my two daughters to Korea and Japan for 2 weeks. My elder daughter works in Korea, and it will be a opportunity to meet her and have a family vacation. Unfortunatly they could both have holidays together only in august, so a bad timing. It will also be my first opportunity to see bonsai IRL. I'm planning to visit some bonsai related spots while in Seoul and Kyoto.....

Buuuut it will be the first time since I'm into bonsai (exactly 1040 days ) that I'm away from home for more than 24 hours. To make things worse we are in summer and under temperatures up to 40ºC (104F). So I'm really scared about my +120 pots . This situation could mean the partial or total loss of all my trees.
I know no one that can help me, but my neighbour. But she knows nothing about gardening, so I can´t dare (or risk) to tell her to be watering my trees 2 to 3 times a day for 2 weeks, and explaining her, when, how and how much in each pot.
So my only chance is to use an automated watering system.
First decision was to put my trees over the ground (about 2 cm into it, so the pot holes are in contact with the humid ground), and under trees (to increase shade and humidity, and reduce temperature). This was the place I choose ( half an hour sun in the morning and the same in the afternoon at most)

Then, I bought a wifi watering controller (https://garza.es/collections/domotica-jardin), a Gardena sprinkler ( https://www.gardena.com/int/product...llating-sprinkler-aquazoom-compact/967976501/ ), and a wifi camera:

Some days ago I put about 80% of my collection in place to begin the tests and checks (I'm also placing some hi-technology wind related protections)

After adjusting the sprinkler, I've been watching where and how the watering works to put each tree in its optimal position (for instance my pines, dawn redwoods and deciduous can't share the same watering schedule). I'm now adjusting the time of the day I will be watering and for how long depending on each day conditions. with great results so far. I will be doing this for the next 4 days before I leave.
If everything goes right, while away, I will be able to watch my trees, supervise the watering and adjust the watering program with the forecasts or order a direct watering.
If there is a water supply problem my 500 liters deposit and pump system will automatically go on.
If , even for a moment, there is a power cut, my system will fail, and it will only be possible to reboot it being there. I think there is less than a 5% chance that this can happen in those days. So, If I detect this situation in my daily checks, I will tell my neighbor to water with a hose I've prepared for her.
I think there is nothing else I can do. I assume there will be damages, but I hope 15-20 days will not be enough time to destroy any of my trees.

So, can you see any flaws in my plan? Something I could be missing?.... anyway, wish me luck!

Your plan is too high tech. Get a battery-powered hose timer and a garden sprinkler as a backup plan. Set your fancy system to water the trees at the normal times, and set your battery-powered system to water the trees an hour later. When the high-tech system fails, your trees will still be watered. For just two weeks, it'll be impossible to keep the trees too wet.
 
I think your preparation is very good and you have thought about it very well in advance.
If your system fails and you have to call your neighbour to water the trees I don't think there will be a problem if she waters all trees thoroughly.
In two weeks time it is hardly impossible to overwater the trees with temps up to 40 degrees so you should be fine.

Have fun with your daughters in Korea and Japan!!
 
I don't recall if there is a bonsai nursery in Seoul... I know there are several botanical gardens that I visited while I was there, but the only time I remember any bonsai trees was at a winter exhibition. Nevertheless, Seoul is a beautiful city, so enjoy. Food is amazing, if you are not afraid of pork, you need to eat sam-gyup-sal.
 
I can understand your nervousness in this situation. I just came back from a 6 days vacation. I was able to have a coworker came by to water the trees each evening... We basically hit 40 degree C each day for many weeks already. Well only one broken pot and a few trees are out of its pot. Some of the Nippon Lily that I did an experiment with are dead. A lot of soil got blown out of the pots from the spray of the water.

I hope the system work perfectly so you can enjoy your vacation with your daughters.
 
I understand your concerns. I am forced to travel quite a bit for work so I have had to leave my trees many times over the years.

I’ve found that the best solution is a combination of automatic watering and help from a trusted friend. Automatic is great but sometimes doesn’t get every tree fully saturated depending on location, angle of spray, etc. You might want to ask your neighbor to do a supplemental watering every 2-3 days depending on her availability.

I get a lot of an anxiety when I have to leave my trees, but for the most part they have all been just fine when I return home to them. :)

Good luck!
 
Enjoy your visit to Korea and Japan. Spend time to connect well with your daughters. They are the most important connection on your trip. And enjoy fantastic food!

I usually rely on neighbors or a close friend to water. I just don’t have enough confidence in automated watering. I’m sure your system is fine though. The lack of confidence is just a me-thing.
 
On what Canary Island are you @Fidur ?
I'm going there in two weeks and I'd be happy to check on your plants for you.

If you can, make a video for your neighbor on how you water your trees. This helped a lot of my caretakers over the years to know which tree to water "long" and which ones to water "short" and also how to be as effective as possible about it; shouldn't take more than 2 minutes in my case.

I second this idea and made a video for my wife when I needed to be away for 10 days this summer. Then again, I'm in NY and we've had a mild summer so watering even once a day was enough (and every other was fine too). Also, test the watering system a few times before you go.

You're probably right. I've always tried to keep things easy, and maybe I went too far. My need to control every possible situation over this process speaks volumes about how much I love and care for my colection, but I agree your plan is wiser.

Thanks for that wise suggestion!

Yeah, quality time with my family is very valuable to me!. Thanks!

I live in Gran Canaria. What a great offer!!. I will be about to come back when you come. If you like we can meet to have a drink and a bonsai conversation, including a visit to my bonsai collection :)
I also think the video is a great idea!

Anyway, I'll update this thread when I come back. Hope to give good news 🤞
 
I went back to my thread from the garden I visited in Kyoto, and noticed you had already commented on there saying you'll be in Kyoto soon! I don't have anything to add about the plant care, but I do admire and empathize with your concern.

Have a great time with your daughter's, that's the most important thing. My son has been watering when we're gone, he does OK. I always water with a watering can and he uses a hose, so they don't get watered as well but it's better than nothing. I find $ gives him motivation to do well.
 
+1 for go battery!

Here's my resource.

Oh boy... Korea is an exceptional country for bonsai lovers... I think it's somewhere between Japan and China in terms of style, approach and material quality and availability. I used to live there for almost 6 years prior to coming to China and this was where I "restored" my bonsai as a hobby.

@Fidur ... if you're up for it let me know where you go in Korea. If there is anything specific you'll be looking for maybe I can help.

Oh thanks, but I have already contacted with Korea Bonsai Museum, a private bonsai nurserie and school (http://www.ktreedesign.com/ ) for a visit. Also I plan to visit the bonsai collection at the Changgyeonggung green house.
This will be more than enough for someone who has never seen a real bonsai but in pictures :D.
 
Test and try get a neighbour to check.
Just home after my 7 day vacation and my father in law came daily. All soils disturbed by the big 10L watering can without spray nozzle but my little trees look better then ever. Quite frustrating to see my trees this happy after my sensitive care...
Enjoy your holidays!
