EXPERIMENTS IN HORTICULTURE (WINTER BOREDOM EDITION)

February 17, 2015

I have a few horticultural experiments going on in my house right now. This is unusual for me because I rarely have the patience for such things, but this time of year calls for finding new things to amuse ones self.

All of the cuttings are currently residing in one pot, but if they root successfully I’ll pot them on in their own personal pots. If it all works I should have trees in like 15 years. Ha!

About six weeks ago, maybe a little less, I took cuttings from the new white spruce (Picea glauca ‘Hudsonii’) we planted last year. So far it’s been a lovely little tree and one I wouldn’t mind having a few more of. It’s the first time I’ve tried to propagate an evergreen and from what I’ve read, it will take up to 13 weeks for the cuttings to root, so I’ve not even tried to check on them yet. The good news is that they appear to still be alive in their little mini greenhouse (i.e. a plastic bag over the pot).

The cuttings live in their own mini greenhouse while they hopefully root.
 

If it works, I’ll be sure to tell you what I did, but I don’t want to share a method that is a failure if it doesn’t work.

The other experiment going has to do with sweet peas. According to my little seed chart, sweet peas are not scheduled to be sown until March 15 at the earliest in my area, but I want to do everything I can to make sure that they are successful.

There is some debate as to how to start sweet peas. OK, there is a lot of debate involving everything from timing to the type of pots you should start them in to what to do with the seeds before you sow them. The last bit is what my mini experiment focuses on.

Some people say to soak the seeds. Other suggest nicking them. And several of the British gardening television presenters suggest doing absolutely nothing to them other than sticking them in the soil.

Blog reader Casa Mariposa reminded me to soak the seeds overnight and said hers sprouted in just a couple days by doing that. The growing instructions that came with my Owl’s Acres Sweet Peas order (yeah, I’m the freak who orders seeds from England the first time I try to grow sweet peas) strongly suggest nicking or soaking, going so far as to say they don’t recommend even trying them without doing one or the other.

Since I ordered too many seeds (I’ll probably end up giving away whatever I don’t use, so stay tuned if you’re interested in that sort of thing), I’m starting six of them early. I took three of a Spencer variety (long-stemmed, meant for showing and bouquets) called ‘Lake Windemere’ and three of grandiflora ‘Fire and Ice’ and potted them up, one pot per variety (which is how I intend to sow them in March). For each variety, I nicked one seed, soaked another for 22 hours and did nothing to the third seed.

My sweet pea experiment is underway in the basement where the two pots are on a heating mat and cardboard makes sure that all light (not that there’s much down there) is blocked.

The two pots are currently on the seed-starting mat (set to about 60 degrees but it’s having a hard time getting to that temp for some reason, maybe because the pots are somewhat large) and I’ll be keeping an eye on what happens.

Of course I’ll report the results to you when I have some, which maybe be in a few weeks because it can take some time for sweet peas to germinate.

    I'm a soaker for sweet peas and other hard seeds like that. Need to get a warming mat!!

    I keep looking at my seed tray wishing I could start things. But I've done that too early before and land up with leggy plants that are hanging around waiting for spring. Kind of like us right now. We had 6" more snow last night!!!

      It is SO hard not to rush to starting things, although I know that's no good. Plus, I also know that last year I was really sick of tending to all of those little plants by the time it was warm enough to put them outside.

    I soaked mine, stuck them in a Solo cup full of soil and put them under a grow light in my coldish basement and they are huge! I've had to pinch them back three times! Was the shipping on your seeds crazy expensive? I'm growing a few extra fragrant varieties I bought from Botanical Interests. I started mine waaaay too early and think they're going to bloom while still under my lights. Hooray!

      Oh wow! I hope mine are as successful as yours! I think the shipping was less than $10, so not horrible. I'm pretty sure I placed that order after a cocktail hour. 🙂

Have I mentioned that Hydrangea serrata is trying very hard to become my favorite hydrangea? This is @pwcolorchoice Tiny Tuff Stuff and I do treat the soil to try to blue it up. This gradient effect was nothing I intended but I just loved how it turned out. Hardy, small in stature, beautiful blooms, it really does tick a lot of boxes.

My pre-sprouting sweet peas are already starting to presprout, which means bouquets like this are in the cards once again. I’m working on a sweet pea growing guide. I know some of you are way ahead of me but I’ll try to cover all the things so even if you’ve already got them going it may help. Side note: Damn that’s a pretty little bouquet.

I’m really determined to have a good rose year. I go back and forth on having these in the garden. No matter what anyone else says, I do find them to be more work than other plants in our climate. But then I see this (Alnwick rose) and I get all melty and think, “Yep, totally worth it.”

A year ago today (sort of ... it was Feb. 29) we were fortunate to have @fergusmustafasabrigarrett and @nickmccland come to Wisconsin to talk gardening and drink old-fashioneds. I think it was the last big event for most of us. At least we locked down on a good note.
