Problems with starting from seed, Luna Red hardy hibiscus
Comments (15)My brother walks in the room, says where are you going to put all of these hibiscus and datura seedlings and I tell him, It's not how many there are, it's how many are going to live. If I start with 10 of the same kind, I'm sure to get 2-3. There's just too many things that can go wrong with seedlings, so if I want a plant from seed bad enough I'll order or get enough to ensure I get 1...lol You probably shouldn't have had that compost in for seedlings, and no fertilizer at all until they've got at least their second set of leaves (1st true set) but from the sounds of it, your remanders are strong and doing fine. Use a very little fertilizer at first...as in real diluted, just enough to get them use to it. You'll have to feel your way through as to when to add more as all plants have thresholds for such things. I like researching things but I can't remember how much I fertilized. Though I don't know if that's necessary if you already have compost in your mix. Now, I haven't grown lunars, but I have grown 5+ other kinds. Your roots, I believe, are little tubers and they must stay attached to the neck of the plant when you transplant, much like dahlia's except longer and thinner tubers relative to the plant size. They are stonger than veining type of roots. All my hardy hibiscus shoot straight out, in one direction or another. I expect yours are probably curling around the bottom of the pot and you should have them in ever bigger sized pots. Just keep in mind, a root bound pot means there is so much root in the pot that the water just runs right over the roots and out the bottom, with nothing much to help keep the water near the roots for a long enough time. They will grow much faster in their second year and probably be able to reach full heighth in the third. Albeit those newer kinds of hibiscus (especially to most of us here in Canada)do each have their own characteristics and your own growing environment and care will have a lot to say about how fast they'll grow. But from what I've read and I've read on almost every kind, have the same growth biology...but there are always exceptions to the rules, such as Lord Baltimore and others that can grow pretty tall. - Sandy...See Morehardy dinner plate hibiscus grown from seed, how long to bloom
Comments (9)HI there, I know this question is a year old but I've just joined the forum! I live in France and grew this Galaxy variety for the first time last Spring (06). I germinated 6 out of the whole packet (expensive!). The first 3 produced huge flowers (19 cm across)in July/August. One white, one pink and one red. One just unexpectedly died and the other two haven't produced any flowers. They were planted, still in their pots, in my veg patch and got full sun. Didn't feed them but will start to do this if I can get them through the winter. Incidentally, they are presently 3' tall. I first saw them in a border near my home and today, I revisited to see how they were faring (as it is now Autumn) and how the owners had treated them. They were covered in seedpods so I picked a few for next year - wish I had noted the colours when I first saw them. They haven't been pruned but I did notice that they were extremely bushy with many stems from the crown. Hope this is of some interest....See Morehardy hibiscus from seed
Comments (3)Jackie, I never thought I'd buy hardy hib seeds either, but after several attempts at finding a hardy hib and failing, I decided to order from Parks SEeds in 1989. I can't recall the number of seeds they sent, but only one germinated..enough for 1 plant..I started the seeds in spring, set in a south window after it germinated. I really didn't think it'd do much, but after planting in the ground it really took off..To this day, that HIb emerges from the earth in mid summer..It has the largest, 12-14" diameter red flowers. I can't recall if it's a Disco Belle or Southern Belle, but one of the two. So, if people want another hib, go for it..what have you got to lose? You'd be surprised..Toni...See MoreHelp with planting Hardy Hibiscus seeds
Comments (5)Save time and effort and wait until the weather is HOT outside. These are relatives of and similar to okra. Wet a double thickness of paper towels. Sprinkle the seeds on the paper towels and roll them tightly. Let them sit overnight. When the weather is hot, I fill a large pan (need slow drainage) with soil and SOAK it with water. Let it sit in the hot sun all day. The seeds will crack and some may have a small root sprout. Carefully plant them in the hot soil. I place the pan in the greenhouse and I water every day. They will sprout within a week. They will grow quickly in the heat....See More- 17 years ago
