Thanks for posting that!
I have some shrubs I want to move and this will probably help them recover.

I like this idea!! I have some shrubs too far from the hose that need water.

This is a great idea.
My cousin does this for slow drip watering in an astilbe planting.She only drills 1 hole for a slower drip.

I put a small hole in the bottom of a jug, set it next to a favored plant, and fill it with liquid fertilizer. The whole gallon soaks slowly and deeply into the soil/ root system instead of running off on the ground

I find it drains too fast with screwdriver holes. I punch pin holes in my jug, (use a needle or safety pin) and set them on potted plants when I'm going away for a weekend. The gallon size drips slowly enough to last 3 or 4 days. I like the fertilizer idea, though. Must try that!

I put many holes in the bottles because over time, dirt will fill the holes and they get plugged up. This may make for a faster deep watering for a short while. Eventually it will slow down as the holes get plugged with soil from the outside. The more holes you have in it increases the chances that you will end up with a few open ones.

I've seen proposals for something similar to the "deep-feed / deep-water" idea.

One scheme replaced your jug with a really big tin can, the other used a 4" or 6" diameter length of PVC.

They both had holes in the bottom, but they filled the tub / can / jug with manure, raw compost-makings, or finished compost.

The idea was that the water would leach out Good Juices while it perked through the compost.
Aerated, weak compost tea or manure tea would come out the bottom, near plant roots.

The proposal that urged putting raw scraps into the 6" tube made his underground holes big (like 1" or 1.5"), so that worms would be attracted and go in and out, carrying the compost to a radius of several feet as worm castings. . He called it something like spot-vermicomposting.

I forget whether they suggested putting a slow drip irrigation emitter at the top of the tube, but it sounds good to me.

But I haven't tried it myself yet.

I've seen those, too.
I have put my compost bin as one "wall" of my raised vegetable bin so the wormies have close access there.
Not watering through it though, just composting.

Ohhh! Great idea. Maybe a moat filled with compost makings ...
