    Wow great deal for the seed package for a dollar. Can’t beat that .



  2. David Klein on July 30, 2021 at 8:44 pm

    Marcia Klein here. After watching this video I just ordered a bunch of your flower seeds to start indoors here in Mid-Michigan. We a very very cold right now. Love your videos. Happy gardening!



  3. Brittany Garrison on July 30, 2021 at 8:46 pm

    Finally an explanation my autistic mind can follow. Thank you, sir.



  4. Ana Cecilia Hannickel on July 30, 2021 at 8:47 pm

    Thanks for your videos Gary! I need some advice: I ordered a few seeds that specifically say that direct-sow isn’t recommended. They instruct you start a few weeks before last frost. The thing is, I’m in zone 9b, and my last frost date was February 13. So since it’s PAST my last frost date, can I still start them indoors & transplant once they’re bigger? Or do I need to wait till next year & start them in January? I don’t want to waste a bunch of seeds. They’re all annuals by the way. I’m trying to start a cut flower garden.



  5. Jenny Stimson on July 30, 2021 at 8:51 pm

    Great video but how do you know how much growth the plant needs indoors before going outside? Could you expand on how you calculate that? I’m sitting here with my seeds and sharpie.



  6. Bianca Venute on July 30, 2021 at 8:54 pm

    Great video, thanks for the help! 🙂



  7. White Rabbit on July 30, 2021 at 8:54 pm

    The "when" makes sense up until deciding the # of weeks that you wrote at the bottom. No real explanation of where you come up with that number. Not very helpful.



  8. Jodie Blinstone on July 30, 2021 at 8:55 pm

    I’m just wondering – where do you find the information on how long it takes flowers to bloom? Or is this just from experience? I’m in the UK and the back of my seed packet doesn’t tell me this.



  9. Vincent1324. on July 30, 2021 at 8:55 pm

    Do you need to refrigerate you wildflower seeds to germinate them before planting?



  10. roger weber on July 30, 2021 at 8:55 pm

    Hi Gary. I always enjoy your videos for veggies and just getting starting started on growing our flowers. I always use a heat mat for veggies should i do the same for my flower seeds?



  11. Nathan Allen Pinard on July 30, 2021 at 8:57 pm

    I partially now want to make tiny flower plants



  12. Thanh Tu on July 30, 2021 at 8:58 pm

    Where do you get those plastic cells?



  13. Cindy on July 30, 2021 at 9:00 pm

    I want to plant my own Annual’s for my window boxes this year any suggestions on smaller plants that do great in a window box?



  14. Tri Nguyen Dang on July 30, 2021 at 9:01 pm

    How often you water after the first water and how far apart



  15. Lar on July 30, 2021 at 9:04 pm

    I am now confused. When I go to the nursery and buy my flowers, they are already blooming. For example, I buy a flat of Marigolds in full bloom and transplant them in my gardens. But I am not to allow them to bloom when I start them inside?



  16. Lass A on July 30, 2021 at 9:04 pm

    Thank you so much! I enjoy your videos and all your information.



  17. mplslawnguy on July 30, 2021 at 9:04 pm

    How did you decide how long you wanted them growing inside, before transplanting outside? I’m not sure where you came up with those timelines. Will these work, regardless of how small they are at transplant time or do they need to put on a little size first?



  18. shervon lewis on July 30, 2021 at 9:05 pm

    What about us in the Caribbean



  19. Karen Prescher on July 30, 2021 at 9:05 pm

    Have you ever grown the Monarch of the veldt daisy. I cant get the seeds to germinate. Help!



  20. Martin Martinez on July 30, 2021 at 9:06 pm

    Thank you so much for your help. Glad I found your channel. God bless you and your family.



  21. Stephen Luna on July 30, 2021 at 9:06 pm

    I’ve been struggling with my flower seeds, thanks for doing this video



  22. Jan Williams on July 30, 2021 at 9:07 pm

    Hi Gary, this is my first year growing any seeds inside. I watched this video twice and I guess I’m a little dim to have picked up how you determine when to start any particular flower indoors. You have written germination time – I certainly get that – and you have bloom time – I get that as well. How one connects the 4 and even 6 to 8 weeks you have written on the bottom is what I’m confused about. Can you please clear that up for me as I’m right now in my planning stage for starting the flowers. Thanks. You have a tremendous amount of videos to watch and I appreciate that.



  23. Steve O_O on July 30, 2021 at 9:08 pm

    Thanks so much for this video.



  24. Baron Wolf on July 30, 2021 at 9:09 pm

    What about if you start the seeds in a greenhouse? What suggestions do you have on start dates? I am putting in a 6×8 greenhouse this summer and want to be prepared in the spring. Just not sure if it is the same as starting “indoors”. I guess so if temps remain in the 70s. Thoughts?



  25. Andrew Raissis on July 30, 2021 at 9:11 pm

    Gary- you are among my go-to YouTubers for gardening information. Question- why are you planting those seeds and not your own from your shop? (You have them in the bag right there!) thanks



  26. Sour Tea on July 30, 2021 at 9:16 pm

    Will some annuals survive a Texas winter where it’s not *that* bad compared to the north? I’m also planting them in pots and not planning on putting them in the ground, so can they stay outside the whole time?



  27. timothy hogarth on July 30, 2021 at 9:16 pm

    Grow lights for cosmos starting now in philadelphia



  28. Helmut Sasse on July 30, 2021 at 9:18 pm

    Hi Gary.
    When should i start my impatiens live in zone 5??
    Helmut



  29. AquaLady on July 30, 2021 at 9:19 pm

    I just have a big ol box of random seeds. You were always my first choice for gardening. This came as a pleasant surprise!



  30. Ira Johnson on July 30, 2021 at 9:22 pm

    I want to plant them in the front of my yard in. Kinda like rectangular patch. I just want to do it cause I know someone who likes flowers ,I think idk anymore, so they can see them from a distance cause of the new normal and know that’s for them. I planted them for looks and letting you know it’s my way of saying that.



  31. Stephen Luna on July 30, 2021 at 9:23 pm

    will adding cinnamon to the top cause issues with flower seeds?



  32. Love always Jasmine on July 30, 2021 at 9:23 pm

    Any idea when I can sow Icelandic poppies? I’m in zone 7.

    My wife is planning to start her own flower plants this year, so this video is very informational. Thank you for sharing your knowledge and experience.



  35. Jessica Hernandez on July 30, 2021 at 9:27 pm

    So you want to allow them some growth indoors but also outdoors before they bloom ? For example, if they bloom in 60 days that’s about 8 weeks. Would you let them grow for 4 weeks indoors and then take them out ?



  36. Dragan Curak on July 30, 2021 at 9:28 pm

    Gary u have everything for gardening. even voice , I am learning so much from u thank you very much for explanation and putting on your professional expertise.if and whenever u in Adelaide South Australia u have free sleeping and food and drink, all the best mate

  38. Ree Intili on July 30, 2021 at 9:32 pm

    Do you ever genuinely say thank you to folks on your channel? Constantly promoting stuff. Sad



  39. Top Noch on July 30, 2021 at 9:32 pm

    Came here to find out one thing and all I needed to do was click the chapter! I love that.. To the point. I can come back when I need the rest of the video. Very well done thank you



  41. Sean-Michael Surprenant on July 30, 2021 at 9:36 pm

    Unfortunately, some of my black eyed Susan vines began to flower inside even though I took all factors into consideration! What can I do to ensure they will thrive when I plant them outside? Are they a lost cause since they began to flower inside?



  42. mizcea1 on July 30, 2021 at 9:36 pm

    very helpful and informative, thank you



  43. angela anderson on July 30, 2021 at 9:37 pm

    I always learn from your videos. Would you consider doing a winter sowing method video. That seems to be the craze these days. I trust your judgement.



  44. stevie b on July 30, 2021 at 9:39 pm

    that is so smart, thankyou so much Gary , thats exactly where i’ve been going wrong , i’ve been leaving them in my little growhouse for weeks on end after germinating because i had nowhere to put them



  45. Mini Pillai on July 30, 2021 at 9:43 pm

    Very informative video. Do we need to cold stratify the snapdragon seeds?
