Your going to try your hand at growing?
Yes, the seeds should be here by the last freeze. If they arrive sooner, I will have peat pots going indoors anyway for my peppers and I can get them started. I checked the climate zones map and, although Oklahoma is near the southern limit, they might just make it here.Your going to try your hand at growing?
I hope so. I'll try to find some literature on the pH and shade/sun tolerance. I think the native plants were an understory growth, but if they were planted as hedge rows, they must also tolerate a lot of sun.A little Miracle Grow and you will be good to go!
Thanks Marcus! Then, I'll never be able to grow P. spinosa from seed. The one coming by UPS should make it. It supposedly tolerates USDA zones 4-11, a very broad range, and Tulsa is about in the middle at 6b. I have well-drained silt loam with only moderate morning shade where I want to plant it. I will try to find more this Fall, if it does well.CAS, stratification is basicly similating winter by storing seeds in moist soil in a cold, or sometimers warm, place for a specific period of time. I think Blackthorn has a long stratification period of about 180 days or so. My fear is that even if you get them to germinate that your climate might be too hot, I think you're in zone 7. I stratified Osage orange and Hickory for growing sticks this winter. I'm also growing Honey locust and Black locust, but those don't require stratification
Well, that's only if the websites on the internet are accurate. At least it's not a political website, so there is a chance the information is good.That's great, I didn't know they tolerated all the way down to zone 11, I thought they needed a much colder climate. Good luck!
After doing some reading, 2 months should do the trick nicely.I have a minor certificate in Ornamental Horticulture and a personal interest in propagation technique.
As far as seed stratification goes, 3 to 4 months in the fridge ought to do it.
My single seedling from a nursery in Oregon (?) survived my yard guy's lashing with a weedeater and a winter that included two ice storms. It hasn't grown much and I don't see signs of it's "invasive" habit as yet. It was costly, and when I inquired about another they had none. I'll dig through receipts and see if I can find the name of the nursery.On the USDA web site it says that Blackthorn is naturalized in 15 states in the US and over a wide area of Canada so why is it impossible to buy seedlings? I have searched the internet for 3 years for plants (having failed at my attempt to grow them from seed) and have yet to find a single nursery that has them. Someone has a fence row full of these things that could be cashing in but doesn't know it I guess.
