Planting on a Hillside in Heavy Clay Soils

mines like that but add about 40% fist sized rocks! mine kills every tree Iā€™ve planted directly in it except currants/ elderberries. once i planted in bagged soil on mounds they grow awesome. guess the roots get more air that way. nice job!

I get kind of ridiculous but figure that overdoing planting isnā€™t ever goig to be a bad idea. I planted a Korean pine right off my house in some similar stuff. It had come as a 5-8 gallong tree, a cultivar named ā€˜Avocadraā€™ from very generous friends, the owners of Richā€™s Foxwillow Pines & I dug that hole 5-6 feet wide and shallow (about 24" deep. I remember an image in my mind vividly of a yardstick I measure off ground level and it being 11 or 11.5 in. Today, itā€™s about 8" up off the ground still.

That was sticky more of an burnt orange and chalky-limestone yellow colored clay blend.

I have many different soil types here due to slopes running north to south as well as east to west. Itā€™s really funky. At the bottom is pure wetland clay thatā€™s either sink a rubber boot in and lose the boot going into the next footstep or itā€™s concrete when it dries up.

Near 20 years ago I was hired to plant 19 Braford pears. He wanted a guaranteeā€¦said every tree heā€™d planted on the property had died.

With that piece of knowledge I added about 25% to the price for my work.
(And, I had to replace nothing.)

Finding a way to keep the roots from standing in water is the trick.

Do you have any chlorosis issues in your clay?

I feel like you need some dandelions

And I thought I had heavy soils.

Dax, if you ever get tired of the nursery business, I predict your next business venture will be a brickyard.:slightly_smiling_face:

Nice work!

nasty stuff u got there, how deep does clay go? if anything i donā€™t put enough effort into planting. i put a bunch of 6 to 8ft bare root apples this fall into 8 inch augered holes. hope they liveā€¦ i didnā€™t water them in either but ground was very moist and i tried to work the dirt into the roots well and pack it firmly. they were planted right before ground froze and i figured getting locked into an ice block for winter might not b goodā€¦

In defense of Barkslipā€™s clay. Not all clays are born equal. I suspect that what he has is a Loess soil. Loess is a windborn deposited clay, and is among the most fertile of soils. While it is a clay, it is a very productive clay and plant life tends to thrive in it.

Yeah, this is all tillable/farmable ground so itā€™s sort of premium land to purchase, but, all land in IL is. This is the worst soil I ever saw.

On the top, flat and long/large area of my property itā€™s black loam 18" down before a beautifully-structured clay is found. This is clay when moist & rubbed between your fingers falls apart like sand. I actually have a lot of that type of clay. The poor clay like I showed is on hillsides directly sloping from the bottom wetland. Otherwise it improves greatly the farther its gone away from the wetlandā€¦ however, I still dig holes that contain sticky-clay on occasion that I didnā€™t expect to find.

There are no chlorosis issues @snowflake. And @BlueBerry is exactly right that root rot is the problem. If I plant a tree too close to the bottom flatland that isnā€™t tolerant to poor drainage, itā€™ll die.

@RichardRoundTree I got billions of dandelions. :wink: Just not within these Fall planting photos : )

@TheDerek Iā€™ve dug 7ā€™ down I guess with my hand shovel to plant a pecan with that long of a tap-root. It was yellow, gooey, clay. I was standing in the hole throwing it over my shoulder.

7ft hand dug hole is a crazy level of commitment!

i darn near kill myself digging 2ft-3ftā€¦ down here! 7ft is backhoe work . i guess my clay is pretty fertile because the plants that do survive growing directly in it have had almost no need for fertilizer for many years.

For me the orange clay is usually healthy and the grey clay is usually too compact and anaerobic! I have never gone down passed 3ā€™ though. I love looking at the lines in the soil you can see where the earthworms and nightcrawlers hang out and where they overwinter and then you can see all the dandelion roots and holes from said roots. Not much penetrates the clay!

In Virginia we have orange/red clay. It often is hard as a brick and at best is clumpy unless worked with a tiller which I used on the hole in the pic below. Not the best pic nor the finished product but I recently was working on a spot in my yard for a future peach tree next year that shows the clay. Previously there was an apple tree planted directly in the soil that stunted. There was almost zero root growth after three years.

you have the same issue i do here. every tree has to be planted in a raised bed or its dead in 2-3yrs. i hate clay. ours looks more like barkslips but also a lot of rocks.

That is some crazy stuff Spud. I was watching (years ago) Home and Garden TV channel and a ā€œproā€ landscaper dug a hole (this was Georgia I remember) to put a fragrant vine in where a trellis was and then grabbed bags of black topsoil and filled it in and mulched it! LOL

Talk about bathtub effect and root rot.

i donā€™t even dig a hole in the native dirt. i put down cardboard to smother the grass, put in my raised bed, which is about 20in. high. place the root ball on the cardboard and fill in. the last 3in. gets some woodchips then water well. if its a largish tree i pound in a stake through the cardboard 1st. then plant the tree next to it and tie off for support. all the trees Iā€™ve planted like this are all growing well. Iā€™ve tested a few of the 3 yr old ones and yes they have rooted well into the native soil. i think this way the extra water just drains off on the native soil instead of sitting in a bowl in the clay rotting the roots. the mulch helps to just retain enough moisture. mounds work well too but youā€™re always having to rake the mulch back onto the mound. when given poor growing conditions you do what you have to to adapt your planting strategies. was either do it this way or give up growing trees on my property.

Iā€™m not sure I could dig that deep without something to hold the sides of the hole up. I have the opposite problem of sandy loam. I am impressed with your dedication either way.

I mix in very old manure (turned into soil) with the native dirt to try and avoid the bowl affect (water trapped in a pit). According to Dave Wilson Nursery even in naturally wet areas in your yard you can still raise fruit trees in raised containers. I am in the same situation as you Moose - either I grow in raised containers with amended soil or I loose 75% of my yard to growing fruit trees.

Curious your containers are 20 inches high (mine are usually 10 to 12 inches high) - what are the dimensions of your containers? It is bad enough filling a 4 ft x 4 ft x 1 Ft container manually - add another 8 inches and that turns into a real back breaker.

i make my own soil and haul it in a wheel barrow. its not that bad. some arenā€™t that high. for bigger trees i use 20in. smaller bushes / trees sometimes 10- 12in. is enough. most of mine are 4ā€™x 4ā€™ for some smaller bushes its 3ā€™ x 3ā€™.
