Mind explaining the setup with the bucket and holes and bag like material inside the bucket? Im going to try my hand are planting for seed this spring and want to start getting things setup and ready to go once the seeds come out of the fridge. Your seedling looks good and i look forward to watching the progress.
I will start off by saying that I don't know if my approach is good or not. This is my second attempt at growing chestnuts. The first time I tried a gutter system. Here is a video that inspired me to try that approach. I will also describe below what I'm doing now.
The holes were an attempt at air pruning with the gutter system.
I decided that gutter system didn't work for chestnuts...I think the soil stays to moist. I also may have watered too much before moving to the buckets, I had multiple sprouts forming from the roots, that I didn't have an issue with this year. I also start in smaller pots and then move to these buckets, but in the future I think I'm leaning towards just planting directly in the buckets.
I also don't want to spend a lot of money on this endeavor. I think I paid $2 a bucket off of craigslist. The fabric is landscape fabric from Menards.
I got a hole saw set from harbor freight to cut the holes.

Moving away from the gutter system, I took out the net pots from the bottom of the buckets and covered the hole with a square of landscape fabric. Besides attempting the air pruning, I believe the holes provide good drainage.
I didn't buy fancy growing material...it is a mixture of dirt from the final growing place, compost from the city yard waste area and the soil left over from some old potted plants. This year I also put some acid loving plant fertilizer below the roots of the trees moved to the buckets. I have the philosophy (which may be incorrect) that I don't want to have trees thrive at home because of fancy growing medium and then struggle when they are placed in native soil. Did I mention I didn't want to spend much money on this
I hope by using these 6 & 5 gallon buckets the soil is deep enough to give the roots plenty of room until I transplant to the final place. This years growth has be wondering about that which was the reason for the original post.
Finally this has been a wet year, I think I only watered them once or twice...I have enough rain otherwise that I am more worried about them being too wet. I have moved them from a shady sport to a sunnier spot to dry out faster. I think keeping them in the shade during the hottest part of the summer also helps.
