About Neem Oil
Comments (41)There are many products on the market that claim 'neem' as an ingredient. Often, the 'neem' is combined with other insecticides and a vehicle that makes emulsification and thus delivery/application easier. If these products have used neem oil that was altered or obtained by a process other than cold-pressing, the value or effectiveness of the essential ingredient azadirachtin has likely been reduced or negated entirely. I have read reports in these & other forums about growers using products like Bio-Neem by Bonide (and others) and having less than what they consider stellar results, while I continue to use the cold-pressed product, such as is produced by Dyna-Gro, with what I consider very safe and very good results. Remember that neem oil doesn't deliver a huge initial knockdown punch, but it IS a powerful antifeedant and chemosterilizer, rendering current generations unable to feed or progress through metamorphic stages to adulthood, and rendering adults sterile. Cold-pressed neem oil is excellent on mites & works initially in the same way as hort oils work, with the added benefits of the other properties already noted. This from a recent post @ another forum site: "As I consider the prophylactic use of any insecticide, including systemics, I guess I have to say that about the only compound that fits that description for me is neem oil. I over-winter around 100 tropical plants (most are normally grown as houseplants, but my focus is on bonsai) under lights in my basement. About 2 weeks before bring them in, I apply neem oil - then again a day or two before I bring them in. Normally these applications keep insect levels in check all winter, though I may see some scale or mite populations appearing toward winter's tail. If it gets too bad, I'll do a neem application & hold out until I get the plants outdoors where the increase in the plant's metabolism and thus natural defenses, along with the increase in beneficial predators, usually completely eliminates the trouble. The bio-compounds plants use to repel plants are a by-product of the plant's metabolism. Plants with high energy reserves and plants growing with good vitality are much better protected 'naturally' from insect predation, which is why plants in low light and those that are just limping along are far more likely to be troubled by insects. I very often diagnose the occurrence of insect infestations as the end product of poor cultural conditions, and the greatest, most frequent offender is a poor soil." I'm not implying you're using a poor soil; I know you're not, but others might wish to consider the corollary. Al...See MoreMixing Neem with BT?
Comments (14)I live in central FL too, worked at a ranch where owners had $$$ they ordered in dump trucks of "soil" which After 3yrs working there and in my own lawn /garden THE SOIL makes a world of difference. I lived 11 miles away and I'm here to say it's all in the grounds soil! I can't afford trucks of good rich dark soil; but I can get cow poop free which helps smells a couple of days ;! But I can get over that. I hate the dusty sand I have! It's not close to what I had in Ohio and it's where nothing grows easy aside from weeds, that attract the pesky pests. Then the summers heat and water restrictions on top doesn't help. I've learned that mulch gets yucky with white & yellow mold also attracts many ants, so I don't use that, what I found that does help us the black fabric ground cover. Killed off all growth put down some bagged rich soil, milogranite(?) turned it over, in and around with a shovel raked it smooth (didn't bang /pack it down) put down fresh ground cover *get the thickest you can or double it, I as the ranch use the black with the purple stripes, the green stripe is good too but I feel that should be doubled make sure you lay it down taunt ( well it looks so much better laid out tight AND it makes it easier to plant in, too. You can top it with pea gravel or bigger rocks if you want. However, I'd say leave the mulch away just cuz the ants and fungi and cost to replace and to keep the look appealing you have to fluff it up, add to freshen it up. As well as replace it for the mold it gets underneath ;/ . The ground cover held in place by 8" yard staples where ranch not at home spared those either at a min. One staple every 1 sq foot. The ranch has had it this way in some areas for 7 yrs now uncovered too without any weeds rips or showing signs of wear for that matter it looks nice and neat. Then for planting used a razor knife cut "X's" and tucked in and under. Seems to be worker getting better results each year. ✌🏼 Thank care of your ground and it will take care of you!

Comments (5)I have found neem oil is well tolerated on some plants, but damaging to others. Neem oil appears to work well on the broad tougher leaf plants. On the other hand, it burns my ferns and shrimp vines. It should be noted that shrimp vines do not like any foliar spray, even 💦 water. I use a cold pressed variety of neem oil that I must place in the microwave to transform the oil to a liquid state. I heat my water until it simmers. I then take the neem oil and heated water and place it in the blender at the highest possible speed. This will give you properly emulsified neem oil. I believe proper emulsification is critical to obtain an even application of the neem oil solution. If you are unwilling to take these steps, it is better to use the pre-emulsified mixture. if you are fighting fungus gnat, I prefer mosquito bits. However, if you are dealing with a whitefly infestation, mosquito bits will do nothing. In my view neem oil takes a while to work and is not tolerated well by all plants. I try to use it as a systemic poison, but this method takes time. For the broad leaf plants, I prefer to use a dormant oil as a wipe. Unfortunately, it has been my experience that no one thing is a solution for all manner of pest control. Some people swear by cinnamon. Some people swear by diatomaceous earth. And then there are others who prefer insecticidal soaps. Dormant oil has its fans, but like neem oil, can damage foliage. Whatever you do invest in some sticky traps. They are non-toxic and yummy tasting to your pest(s). They are attracted to the yellow color. I wouldn’t be without them since you may think an infestation is gone, but after a few days you will see if you’ve cured the problem. You will also be able to correctly identify your pests. After you’ve identified your pest call the best grower/greenhouse in town to determine their specie recommendation for the treatment of African violets. You may want to glean more than one opinion. I’d suggest your state’s extension agent, but there expertise is more towards commercial growers than indoor hobbyists such as myself....See Moreooops.... Neem oil soil drench....
