Excellent! I’ve been growing delphinium for many years in an attempt to stiffen the stems as to keep them strong and upright when flowering. Your video is absolutely perfect and clear to follow
I also reuse plastic food containers for starting seeds, but never thought to cut the clear plastic ones down to fit as mini-greenhousees. What a great idea. I'm new to growing delphiniums from seed, or at all, because I live in the hot South, but they are so beautiful I wanted to try to grow them. My seedlings all came up and I've transplanted them to larger pots and looking forward to growing them into mature, flowering plants. Fingers crossed!
The paper cover is a brilliant idea! I must try that on other seeds, here the hot dry air dries the top of the soil very quickly, and as the seeds are in the top 1/8" which is where it dried faster, that kills them off in hours. Stay safe! Chris B.
Wow this video is very informative! I just bought some seeds that I like to start this week. I am going to follow your instructions . Thank you very much
If the seeds are good quality you should have no real problems. Ours flowered well the second year and with a little care and fertiliser you can keep them going.
@@johnnyAGardening i am hoping that my delphiniums will grow. I used soil from garden right away and the area where i planted them was above the roots of a tree as we discovered after.. hope they make it
Thanks for that, those particular plants have gone through two seasons, flowering well. Once you get them going they are very rewarding and fairly easy plants. Mulch and fertiliser... they love it.
Questions: I was told to pre-chill the seed packet in the refrigerator for a week first. How do you feel about that one? The second idea was, "plant in the autumn in an unheated greenhouse when temps are fluctuating between 3 04 4 degrees C at night and 12 or 13 degrees in the day. You need that big fluctuating temp to get them to grow". How do you feel about that one?
We store our seeds in the refrigerator so yes, pre chill. Actual germination is best at between 18 and 24C. We sow ours in late winter in mini hot houses, such as in the video. After they germinate they will take colder temps. So you could start the seeds in autumn, with warmth for germination, and then grow them on, over winter in the greenhouse.
See 3:48 The seedlings need to have small leaves. Usually we remove the dome when we are ready to pot them up. IF they are growing (no set backs in temperature) we will sometimes remove the dome and let them grow on to twice this size. Let us know how it goes. The plants that we propagated in this video (2022) are still going strong... almost ready to divide the clump.
I apologize if you did mention it but I must have missed it…how long does it take for them to grow and produce flowers if you start them in late winter?
I just collected seeds from my delphinium. Some of the seeds are still white and haven't dried out yet. Should I separate them to dry out? Also, is it ok if I refrigerate some of them or the dried ones for a week, and replant them this month and just keep them as an indoor plant till next spring? Thanks!
If you want to put more than one seedling into a larger container, how many seedlings per pot would you recommend? My larger pots are the 5 gallon variety. thanks in advance!
Usually they are planted 12 inches apart so that would mean 1 - 2. HOWEVER in a 5 gall container we would grow 3- 4 and fertilise them more. 3 - 4 plants would give a really good display. 1 plant would look lonely but with the foliage maybe OK.. (assuming that the diameter is around 10 inches.)
We start ours in late winter, keep them out of the cold and fertilise them (a lot). Our seeds came from NZ, and they are VERY good quality. Once you get them going they are stunning plants.
20 degrees celicus? Bc 20 fahrenheit is below freezing. Im assuming by your beautiful accent it probably isn't fahrenheit. But I had read a comment on another video it sounded like it needs to be freezing. So I am a little confused.
Usually in the second year they flower well, Although we often have them in the first year and our current ones (from seed0 are in their fourth year, which reminds me to think about dividing them. The outside (newest) pieces are the best to replant....
I did winter sowing in February with regular miracle grow potting soil, I took them out of the container and put them in garden, but I doubt it will be flowering this year
Yes, a lot of confusion with these, we will put it this way, Larkspurs are the wild species both annuals and perennials. Delphiniums are hybrids of the perennial types. So over the years they have changed a lot from the original species. One of the best growers is Dowdeswell Delphiniums in New Zealand, they have some amazing plants. Different growers/hybridisers, produce slightly different looking plants.
@@johnnyAGardening that's cool I have a seed pack I'm starting now labeled delphinium , the one thata already up and grown now looking more fuzzy is larkspur
Hello, friend from afar. First of all, let me introduce my situation. I come from China and have a handicraft studio for juicy plant utensils. We have designed some hand-made utensils of succulent plants with our own copyright and small studio. I see your website experience is very good, so I would like to recommend my handicrafts to you. I'll send you some photos of my products. If you are interested in our handmade products, we hope to get your reply.
