I swear by the stuff, smells like burnt coffee to me but who cares! I have fruit for the food banks and I am grateful. I have a city mold infection on a walnut tree that seems to have migrated to a magnolia tree and a succulent plant. I live in Southern California and the weather is often above 75F. What is the best way to proceed? Neem oil may help, applied as per the instructions above.
But on top of that, I would apply a microbial inoculant like effective microorganisms as well as a health-promoting broad-spectrum fertilizer like liquid sea minerals, as these will help the tree fend off the mold itself.
I think your customers have a right to transparency and honesty. Hello Phil, Will neem oil work on curly leaf on my peach and nectarine tree? I use neem oil commercially on my tamarillo orchard. Is it possible to combine its application with other chemicals like copper, or sulphur or potassium silicate?
Would save a lot of spraying time if it could be. Oils can reduce the effectiveness of these mineral sprays. Ideal would be: 1 control group, 2 neem alone, 3 copper alone, 4 neem and copper together. And then obviously others like sulphur would add even more groups. Hello sir I am from india gujarat I creat my own neem spry for my farm with halp of liquid dish wash emulsifier.
But emusified oil color is brown not milky white It is harmful of my plan or not??? Please halp me for this confusion Thanks.
Paradoxically, neem oil has been shown to help control pathogenic nematodes such as root-knot nematodes. Same question for neem and compost tea. Thinking of neem as a pesticide makes me wonder if it will harm the microbes or mycorrhizae.
I generally come through a few days after neem with EM or compost tea. How close to harvest can I use the neem oil? I have blackberries beginning to ripen and are plagued by japanese beetles and squash ready to pick plagued with squash bugs. I suppose it depends on the type of food. On average, I would probably try to have a week before harvest, but you could run an experiment on some of your plants to see what happens if you spray even later. I recently found some mealybug, just a few, but through out the growing area.
Which means a complete shut down, potentially for many months. Followed up in a few hours or day with neem oil. I know it works, but it discolours most of them. Some plants will be damaged by one or more of those items.
Those will have to be assessed afterwards. I also found some mealy on the roots, of one plant. Just at or below soil level. I have not been able to find any information on successfully killing mealy in the soil. I work very hard to keep my soil microbes healthy and happy. Two questions 1. What strength do I use for a drench. For a spray I use tsp per litres. I can do a follow-up spray sooner with the neem. I have the feeling for soil higher might be the better choice. Have you ever heard of anyone applying a soil drench from below.
I mean sitting the plants in trays of the mixture. I would assume it need to be just enough to absorbed quickly, before the oil and water separate. How about a dip? I know growers use it with other products.
I know it is a problem. Which is always my biggest problem, having to move plant to an area with no direct light for a couple days.
It makes the process very slow. For outdoor plants, I only use neem after the sun has moved away from that area for the day. Yes, this makes sense to me. Yes, I can see how succulents would be especially sensitive. I tell people to apply in the early morning or especially the evening for this reason. Thanks for your questions! Will this work for cinch on lawns?
If yes, what would be the ratio recipe for use in a garden hose sprayer, if that would even be appropriate? Oh and how about those lawn grubs?
Would it work for those too? I should have mentioned that my backyard is 75xfeet. The sprayer for the hose does have a dial on it. Would the water from the hose be too cold for the neem oil I wonder? The 4 Tbsp I mentioned above will only do about square feet, so you would need to do it about 7 times for your square feet.
But conceivably, you could do 16 Tbsp of neem oil with 16 Tbsp of water presuming you have a 2 cup sprayer and that could work. That would cover half of your yard. Again, read my application instructions up above for more info. Hi Phil. Thank you so much for getting back to me. Ok my hose sprayer holds around 5 cups of liquid, it says at the top line 36 oz.
It has a dial that ranges from 3 to 21 gallons. Not sure if it is the same as yours. Can you tell setting the dial it should be set at? Ya, these things are really confusing. And set the sprayer to 21 gallons. I doubt it will be quite as useful on grubs but it may inhibit the beetles from laying their eggs.
Then, slowly pour in 4 Tbsp of neem oil while vigorously mixing the liquid. Then set the hose-end sprayer to setting 10 Tbsp per gallon of water. Will Neem Oil help with Pickle worms. I have been trying to grow Spaghetti Squash for a couple of years now and the pickle worms destroy them. Also getting into summer squashes and cucumbers. Hi, I live in Denver and we have a terrible Japanese Beetle problem and my roses took a hit this year. I purchased the Neem oil as well as the Seaweed fertilizer.
I read that you can mix the two? I have a gallon sprayer what would the amounts of each product be to a gallon of water? How often would I spray the rose bushes? Shake like crazy before and during application to keep it emulsified. And then add 2 Tbsp of seaweed. This amount will do about square feet of garden. I would spray this every 2 weeks. The scientific research on this seems scarce but I found one study that showed some beneficial microorganisms responded favorably. Any thoughts on this?
Also, would I use a higher dilution? So I have a problem, guys. I used organic neem oil, diluted, pure oil mixed with water as it says on the bottle and sprayed my mint, lettuce, cabbage, cucumbers etc….. It tastes awful…. Help please! What do I do now? If you spray the day before harvesting, I expect things would taste pretty bad.
Hi, Thanks for all the info on Neem Oil. One fact that is missing is how much Neem oil mix does one use in a soil drench for fruit trees? I have 3 trees, the largest is about 30 cm in diameter and the other two are about 15cm in diameter. I know how to do the mix now and how to dig the trench, but how much do I put in the trench? I have started using Neem oil this year as I have all types of pests and fungal problems — questions though, my tomatoes are still sticky with Neem oil i assume, even after washing them with water and vinegar.
I sprayed 5 days ago harvested today. Are my tomatoes and vegetables safe to eat or did I sorry too much? You can spray it all the way up until harvest but yes, you need to wash the harvest with soap and water rather than vinegar and water.
We are spraying sq ft with the hose end sprayer. I calculated 1. Your neem and soap amounts look great. So for your 1. Question: Do any these other products address them? If not, do you have a product that does? In my organic raised bed gardens I use horse manure from my horses.
Most of it is composted in an aerated composter that heats up to kill pathogens O2 Compost but before I got that system I was using compost that was probably full of nematodes etc.
But nematodes could be in there too? Hoping the addition of your products will give it a boost. Thanks for any ideas or product you can recommend.
There are many tomato options, and at least a few peppers. In addition, I would keep searching online because I have come across a few organic nematicides that may be useful. Hi Phil, I started my tomato seeds March 9th and today I found a couple tiny flying bugs..
I think on here they called them gnats …I do have tiny showing of my plants and not sure if I can put neem on them yet. I am feeding them water by a teaspoon Yet as they are just peeking. Any suggestions as I see at the top of comments to be careful with seedlings.
I have used neem on large plants outside with great results.. Please email me if there's a reply. Click to see full products list. You can get it here.

When spraying a plant with neem oil—either as a bug treatment or preventive measure—it's important to coat both the tops and bottoms of leaves since bugs love to hang out on the underside of foliage. You should also lightly coat the stems and soil, just in case any critters have made their way to those areas.
Only use neem oil on otherwise healthy plants. If your greenery is yellowing, browning, droopy, or otherwise looks off, it might be dealing with water, sunlight, or nutrient imbalance, and the neem oil could make the problem worse.
Most plant varieties can handle the occasional neem oil spray, but use it sparingly on greenery that has fuzzy leaves some succulents, cactuses, calathea, etc. This texture prefers drier conditions, and any excess moisture can throw it off. Finally, don't apply neem oil to plants that are sitting in a bright window. Before spraying, move your plant into a darker room like the bathroom for application and wait two to three days before putting it back in a sunnier spot.
This should leave enough time for the neem oil to break down. If you notice that your houseplants' leaves have tiny holes, webbing, or a sticky substance, it could be a sign of a pest problem. Look closely to see if you notice any little critters on the tops or underbellies of leaves, and treat with neem oil if you find any more on how to do that below.
Even if your plant is healthy and bug-free, you can apply neem oil every so often as a preventive measure. If you've dealt with bugs in the past or live in a warm, humid climate where insects thrive, you may want to get into the habit.
Neem oil is great for home use because it's natural and nontoxic. Though you don't want to take a swig directly from the bottle, it's safe enough to use on plants and herbs that you plan on eating eventually. It also doesn't have the same ecological concerns as chemical pesticides since it doesn't stick around in the environment. Eventually, it gets completely broken down by plants' microbial colonies. It's also a pretty targeted solution: Since insects actually need to eat the neem oil to feel its effects, it will only kill pests that pose a genuine threat to your plant.
Flies and bees that are just stopping by won't be harmed by it. There are a few drawbacks of neem oil, though. Oakes notes that its strong smell— akin to garlic and sulfur —gives her a headache, so she doesn't use it much. Neem oil can also damage your plants' leaves if used in high quantities, so you always want to follow the instructions on the bottle before spraying.
If you're taking care of your houseplants with good lighting , proper watering and fertilizing , and well-draining soil, you shouldn't have to worry too much about bugs. But for those times when spider mites or aphids sneak in, neem oil is a good natural pesticide to have on hand.
