Re: Mrs.Green windowsills-growing cacti against the odds (links on page 9)

That Fero looks in survival mode. I hope it plumps up soon. You kept it on moist substrate for 3 weeks? How bold. :)

Re: Looking For Dyna-Gro All-Pro 7-7-7 Replacement

So it's basically: 1 gallon of water + 3,5 ml Flora Micro + 3,5 ml Flora Bloom + 7 grams 0-0-52 potassium sulfate. When not storing a stock of diluted potassium sulfate, but rather adding it on the go, is distilled water, R/O water or rain water of importance? I acidify my tap water to 5,5 with oak ...

Re: Looking For Dyna-Gro All-Pro 7-7-7 Replacement

Fantastic! It's also widely available in Europe, thus ending my quest for Dyna-Gro. Thanks! Regarding the potassium sulfate, would the following product work: https://bionovanutrients.com/Bionova-K-20/10062Z ? Or perhaps this: https://www.aquascaper.be/en/potassium-sulfate-500-gr-k2so4.html ? What's...

Re: Systemic insecticides: spray or pour?

Thanks keith for your reply. Flupiradifurone is a relatively new product on the market here. I've researched it and the compound was patented in 2015. According to the producer is it not a neonicotonoid, but some scientific articles do say it has a lot of similarities. It should be safer for bees th...

Systemic insecticides: spray or pour?

I have access to a few systemic insectides where I am at (Belgium, Europe) such as: Sanium concentrate (Protect Garden) - 25 g/l flupiradifurone - up to 8 weeks of protection Multisect (KB) - 5g/l acetamiprid - up to 3/4 weeks of protection Perfekthion (BASF) - 400 g/l Dimethoat All of these insecti...

Re: A surprise in the greenhouse.

I do love the look of those dark spines. It just started growing all of a sudden or did you recently repot?

Re: Watering question

Usually moisture meters don't work properly in porous substrates. I also see you have gravel as a top dressing and a plastic pot. Those two combined with non-porous soil could explain your situation. But again, don't entirely rely on moisture meters.

Re: Spider mites on a few of my 9 month seedlings

I’ve read 70% IPA takes longer to evaporate due to the lower alcochol content, which makes it more effective for disinfectant purposes. I don’t know how this translates to bug control though.

Re: Helping Large Cactus Recover from Significant Mite Attack

I think greenknight gave a good answer. I concur with anttisepp, it needs more light. Are you able to put it outside? I don’t have any experience with growing lights, but make sure it gets enough of it. Length as well as intensity. There are applications for smartphones with which you can measure li...

Re: Spider mites on a few of my 9 month seedlings

I don't know if Neem Oil helps against spider mites. I used it in the past for scale, but it can have adverse effects on the wax layer on some succulents.

Re: Spider mites on a few of my 9 month seedlings

Depends on what you got access to...
A quick way to temporarily knock them off would be isopropyl alcochol (2-propanol). A 70% concentration is often recommended, but I've used a 100% IPA on adult plants with no side effects. You have to move quickly though.

Cyzmic CS Lambda cyhalothrin I used it a second time in March and will re-apply in May, this weekend It seems to be working well for Mealies, fungus gnats and most other pests It doesn't completely eliminate Thrips, but keeps them down, I first water everything heavily with regular water Then go ov...

Re: The Good, the Bad and the Ugly

I got some new members for the family. These are most likely the last specimens I will get from the botanical garden. I think I overstayed my welcome. :) Euphorbia meloformis (?), Rebutia pygmea, Agave toumeyana var. bella, Euphorbia schoenlandii (?) IMG_1306.JPG IMG_1307.JPG IMG_1329.JPG IMG_1330.J...

Are those variegated Astrophytums or did they have a bit too much sun?

Do some of you use the application 'Pl@ntNet' (works for both mobile phone and desktop)? It's a peer reviewed plant identification app. https://identify.plantnet.org/the-plant-list/identify It's not waterproof, but seems to work for the most common species. I uploaded all the images of the botanical...
