It can be fun to breed your own zinnias - Part 15
Comments (100)pansyloverandgrower, "So from what I understand, is that you can take cuttings from zinnias and produce a plant from them? I did not know you could do that." That's not surprising. Most books on plant propagation don't list zinnias as something that you can grow from cuttings. You do need to use some Physan 20 to keep the cuttings from rotting, and of course some rooting hormone and humidity domes to keep the cuttings from wilting until they have time to strike some roots (about 10 days). So I guess you could say that it is not easy to grow zinnias from cuttings, but it can be done. I do it primarily to "rescue" good breeder zinnias from an impending killing frost. And, in the case of my "Dinosaur Zinnia", I used cuttings to provide a greater seed yield than was possible from a single plant. Zinnia cuttings propagation details and pictures were provided in earlier parts of this message series. "...especially the tissue culture!" Ah, yes. The tissue culture. Apparently that is considerably more difficult than growing zinnias from cuttings. I have actually successfully taken cuttings from zinnia plants that were themselves grown from cuttings. But so far my attempts at micropropagation of zinnias from tissue culture have failed. Right now I am concentrating on preparing and planting more outdoor seedbeds for my zinnias, so my tissue culture experiments are "on hold" right now. But I consider it an imperative that I learn to grow zinnias from tissue cultures. My initial attempts used a technique that works for African Violet leaf disc explants, but apparently zinnia tissue needs stronger plant growth hormones than African Violet leaves need. That is not too surprising, because some growers propagate African Violets from leaves without using tissue culture. I plan to use stronger doses of BAP (benzylaminopurine) and also try TDZ (thidiazuron) to stimulate shoot production from zinnia callus tissue. I will report on my progress when it occurs. Tissue culture could be very helpful in creating new strains of zinnias. "I also need your help here...I have some zinnias, about 1.5 months old, 11 of them. they are very small and have not bloomed yet: ..." See my response to your separate message thread. I think you may be trying to grow zinnias under conditions that are more challenging than what most of us face. Actually, zinnias are considered easy to grow in most climates. But you may need some special techniques if you are living in Washington state, because zinnias need full sun. Please give us some more information about your zinnia growing situation. Your description of your plants sounds very "un-zinnia-like". If possible, could you post a picture of them? ZM...See MoreImportant! New Vaccine protocols
Comments (7)These protocols are not really that new, nor are they Dr. Dodd's- a task force consisting of many distinguished veterinarians produced the guidelines, and Dr. Dodd is NOT one of the authors. The canine protocols first changed in 2003 and were updated in 2006. The feline protocols were first established in 2006. Dr. Richard Ford, one of the authors of the protocols, is one of my teachers, so I am very well familiar with the subject. Here is an article written by Dr. Ford on the subject. Please read specifically the section titled "The AAHA Canine Vaccine Guidelines and the 3 year vaccine." Oh, and NC State CVM does NOT follow Dr. Dodd's protocols; vaccines are left to the discretion of the veterinarian following a risk assessment for each individual pet. For example, Rotties and Dobes are recommended to return at 20 weeks for a 4th parvo booster due to their extended duration of maternal antibodies, while other breeds are not. Finally the statement that "Once the initial series of puppy or kitten vaccinations and first annual vaccinations are completed, immunity from MLV vaccines persists for life" is NOT true unless your dog or cat only lives to be 7 years old. They duration of immunity is greater than 7 years, but how much greater is unknown. Sorry to burst your bubble, but I do believe in giving credit where credit is due, and Dr. Dodd is NOT an author of the vaccine protocols, nor would NC State use her protocols when we have our own author of the protocols on staff. Finally, it is VERY important to read the section on the "3-year vaccines" because that is NOT what the authors intended. They intend for each dog and cat to be assessed for risk and vaccinated accordingly. Any vet who uses the same vaccine schedule for every dog is being lazy and not doing his/her job correctly, IMVHO. Here is a link that might be useful: Dr. Ford on the vaccine protocols...See MoreNeed privacy hedge < 10ft wide, that grows 10-20'
Comments (11)That's a new one! I'll check into it :) Is there a reason to go Skip Laurel vs Prague Vibernum or vice versa? The major minus for the skip is that cost $40 a plant vs approx $10 for Green Giant or (the now ruled out) North Privet I'll be pricing Viburnum next :) Arbor Day tree finder also recommended purple Sand Leaf Cherry (prunus x cisterna) Any thoughts on that? I appreciate all the info-- I am trying to learn as much as I can before doing any work :)...See MoreFrom a friend recovering from the virus
Comments (79)Me, too, Mtn. I have one moving in next weekend. But I was talking with a friend today who's a nurse practitioner for a downtown Chicago hospital, and she tracks covid numbers. She said there's so far been no noticeable uptick in cases since Lollapalooza. I didn't confirm this myself--just relied on what she told me. Her son went, and another friend's daughters went, too. (My kids did their one-and-done Lolla pre-covid and had no desire to return this year.) The kids I know who attended tested afterward, and perhaps the surge is yet to come. I don't know. I'm not supporting Chicago's decision to host Lolla again. I believe it was pretty reckless to do so. But it does give me hope that jabs and masks and whatever measures were taken that seemingly--at this early point--to have worked, may also help when our kids go back to college. One of mine has jab and mask requirements. Another doesn't have the jab requirement, but masks are required in class and there are incentives for social gatherings to have the jab. My fingers are crossed....See MoreAnnegriet
