Garten GlückNeem Oil Spray - 250ml - Organic Neem Oil with Peppermint & Rosemary for Indoor & Outdoor Plants - Supports Healthy Leaves & Soil - Ideal for Plant Care & Bug Control, Made in Germany

Gnats would give it one star so I'm giving it fiveWorked well in combination with nematodes, sticky traps and covering pot soil with grit. Plus it smells nice!

Purchased as one of my plants had some thrips. My bf had used the same product for years so I bought without checking reviews and then had a massive panic! The only damage it did was to my already dying calathea leaf - it had completely shrivelled by morning but other leaves unaffected. Everyone else is looking healthy and I can't find any bugs now :)

Easy to use as it comes ready mixed. Smells very strong of peppermint which is a nice smell so that's good. Didn't kill the spidermites but that may be because I left it too late to try. However it has worked fantastically against gnats and other little flies. I get them a lot because of my plants and since using this I've noticed they have gone - hopefully this stands the test in summer but I would definitely recommend the product as its safe, natural and pre-mixed for convience and storage. I still have 3/4 of the bottle left after quite a few treatments and a quick spray of healthy plants to keep gnats off - goes a long way.

I think this works quite well, but it's hard to make sure you're only spraying on the soil. Also the smell is awful and lingers for a while - very chemically.

I bought this product for my Crassula ovata (Jade Plant Succulent), as it was starting to get overrun with fungus gnats. I had read up about preventatives of fungus gnats/fungicides/pesticides and wanted to get a product that was non harmful and ideally organic, opting for something with neem in it as it was said to be the next best thing to Hydrogen peroxide. Some neem products for house plants seemed overly expensive but I found this product and decided to give it a go, bought it on the 20th of Dec and it arrived the next day, which is when I first applied it to my Jade plant - 17 days ago now. I had freshened the plant with new soil as I usually do every few months or so, before applying the product as it's instructed - spray all over till the leaves are uniformly wetted with the solution, and repeat application every 72 hours. I thought every 72 hours (3 days) seemed excessive, and is probably advised in order to use up the product faster to encourage re-purchase rather than it actually being beneficial to the plant, but I followed advice and reapplied a further two times to see if it would work.I noticed first that the gnats returned to the plant, despite the soil change and product use, albeit in fewer quantity. The second thing I noticed, after about a week or so it started, that leaves had started to fall off the plant. Due to the time of year and the plant's nature to do this to encourage re-growth I gave the product the benefit of the doubt and didn't blame it immediately, but I stopped applying the product just in case. Since then, more and more leaves have fallen off in greater quantity than my plant's ever shed in the whole time I've had her, and I've noticed that the leaves start to blacken and shrivel up/dimple with this sheen on them which I can only assume is the product's residue - photo attached.For context, I've had this plant for four years, it's survived three house moves and is overall very hardy (despite it's tendency to attract fungus gnats) and is actually a 1/3 of the original plant I bought four years ago - the other two thirds are potted elsewhere in the house, I didn't use the product on them as a control, and they're thriving.Before sitting down to review this, I've just had to very gently clean what's left of my plant's leaves in the hopes that I can remove and remaining residue, and hopefully (fingers crossed) save it.

Good quality. Will recommend

I have a large ficus which had a spider mite infestation. A bit expensive, but no nasty chemicals. I sprayed Day 1, Day 3 and Day 5. I sprayed as much on the underside of the leaves as possible, and surprisingly didn't need to use much (about an eighth of the bottle over the course). My ficus is approximately 3ft tall and the spider mite were gone after the 2nd application, but did a third just in case. I think this treatment is effective after it has dried too. I sprayed it in a room with a painted floor, so put a sheet on the floor first; would suggest you protect any surfaces/furnishings. To me, this was well worth the expense. I wish I'd had it when all my orchids got infected with mealybugs because nothing I used would get rid of them, but I think this would have worked. The smell is not offensive - to me, smelled a bit like mosquito deterrent spray.

I bought it to get read of generic issues with my houseplants. It does work but it's a bit too strong.For sure I got read of fungus but the leaves dried out, not a big problem for well established plants but perhaps not ideal for smaller/younger plant, so people be aware!Product a bit expensive in my opinion but I am happy with the purchase.Example: I used it on my small potted roses and the leaves dried and had fallen. Not a big deal as plants are quite bushy. I used it on my tillandsias bulbosa: the fungus got removed but part of the leaves dried out and is not good aesthetically.
