The place these oaks will be planted is in the Lake Superior snow belt. The soil is several feet of red clay over many feet of sand. Red maple, sugar maple, quaking aspen, yellow birch, red oak, and green ash tend to grow well here. In the spring there tends to be standing water in the low spots. The land is forested and has never been cultivated, giving it a lumpy texture from uprooted ancient trees. Which hybrid will do well?
The existing overstory will be removed to provide sun and rain for the seedlings. What are your recommendations for spacing of new seedlings and how big of an opening should be provided for good growth.
I have found red oaks do well if put into a clearing and surrounding tree allowed to sprout from stumps. I let these grow for several years and then take them down. It seems to produce a nice leader for the red oak.
Any of my hybrids with English Oak as one of the parents do well in clay soils. Make sure the pH is at least 6 and not higher than 7.5. Don't amend the soil, make sure you push the clay that came out of the hole back into the hole. The wet sites should be Swamp White oak, Pin oak or Schuettes oak. Spacing of 30' at the closest and the opening needs to be large enough to provide a minimum of 8 hours of sun with full sun being the best for early acorn production. Thanks for the questions!
I will be planting 128 of your hybrids along with 375 bare-root white oaks and 1000 bare-root white pines on a 4 acre field this spring. I noticed in the previous post you recommended 30' spacing. Does this apply to all your hybrids? What spacing would you recommend for my oak/pine mixed planting?
30' spacing is usually what I recommend as the closest spacing on oaks. There are some oaks like English Fastigate that could be planted at 21' but this would be to close for most naturalized settings. There is no spacing that would be considered to far apart on oaks as they are completely self pollinating. You will need to ask someone more familiar with mixed planting as I have no experience with conifers to give reliable advice. Sorry I couldn't be more help on the subject for Matt but like always thanks for the questions.
Soil that is the in the ground and in the earth we are observing is very special king of the soil have to obtain in the system matters. Types of the soil are so much long term edusson reliable that have forested steps of the needs.
