Which of these mistakes have you made? We'll be reading the comments and answering your questions! -CaliKim & CameraGuy
None yet but we have alot growing this season 🤞🏾😂🎉
Oh my thank you for the tips. I have about 20 plants .First year trying this. Last year I used a q tip to spread the pollen on my cherry tomatoes. Had to many. Lol 😅
I let small melons grow horizontally and they took over my garden. I really liked learning about using a trellis to grow vertically. I will try that next time
Good kim does peppers plants have female flowers and if they do what do I do😊
I usually try to grow the sugar baby melon. I'm great at starting them, transplanting and watering. My problem is training them up a trellis. Eventually, I can't keep up with trellising my melons so the wind up crawling across the raised bed and eventually stop producing more.
I don’t know about anyone else but I feel like I can “see“ where Mac would be in all the shots. I’ve been thinking of Mac, Jerry,and Kim while I’m in my garden with my dogs. I hope you are all doing well ❤ I grew watermelon once and it got a red sap looking fungal disease and they all tasted watery, but they had full fun. But I didn’t fertilize. It made me not want to grow watermelon anymore because I feel like I’m bad at it. I’ve been growing cantaloupe and honeydew melons this year. Maybe I will try again next year with watermelon. Sending positive healing vibes to you and your family ♥️
I've started trying (emphasis on trying) to grow water melons and honeydew melons as a victory garden thing. My problem is, I think I might have moved the water melons more often than they'd like. So the water melon with the most blooms doesn't seem to like the fact that I've moved it to its larger container. I'm giving it plenty of water, but the leaves and blooms aren't opening up.
Also, I'm short on money (hence the victory garden) can you do a video on DIY fertilizer that can be made of things around the house? I've already tried the banana water, and I've heard about the egg shells, but I do happen to have that lying around.
