I need drainage advice

What are some ways to provide good drainage in the rocky, hard Northern Cal red dirt?
&& I was reading how some people lay black garbage bags in their holes first before adding their soil. What benefits does that provide?

dig a huge hole the bigger the better and a pretty nice deepness and fill it with your own dirt.....

yea, I'd say it's clayish. gets really tough and hard to work with in the summer months.Jw, why people do that then?
I know you can grow in that 'cause I seen a picture of a guys grow in South America with just red clay soil plants were stunted in height though. I'd dig down a couple of feet and loosen the sub soil down below with a spading fork (looks like a extra heavy duty pitch fork) add some pulverized gyproc (gypsum lime AKA Calcium Sulfate) that improves drainage in clay soil, about a handful to a hole. Backfill with your native soil and mix in whatever decomposed organic mater that's close by like rotten logs or leaf mold maybe some more gypsum too if you use a lot of leaf mold as it's acidic.
You don't get that much rain down there anyways for water logging to happen anyways right ?

Hahaha I'm not using the red dirt as my soil. I'm hauling in a pre-mix soil with all kinds of goodies already in it, but I was thinking because the ground will be so hard at the bottom of my holes, the water could just sit and become stagnate.
I read somewhere that you can line pebbles or gravel at the bottom of your holes and that helps a little. any truth to that?

not really. As long as your not in a low spot the soil WILL drain just not as fast as sandy soil.
My father was a very successful grain farmer on gray clay soil but if you want to bust your ass replacing the native soil go for it.

I talked to a guy at the place where I'm buying my soil, and he said he's had best results mixing half pre mix soil with the native red dirt which makes the roots stronger and expand more and in turn, making the plants grow bigger.

I am bustin my ass, though :bigjoint: digging 3 ft holes without the dirt being saturated for a couple weeks, and a ton of rocks under the top dirt makes for a nice day of digging

good if you can reuse the same spots again. I suggest you try a little thinner blend on a hole or two and see how that works for future grows.
