Hello Nelson, Two years later and I use your tutorial video to refresh the lesson on spraying fungicide. Third week of June and it's bloom booster, superthrive, cal-mag and seaweed feeding. After dinner I'll spray with Physan-20 and wash the patio. Our cats and dog will be in for the evening so everything will be dry in the morning. Thanks again and kindly remind your viewers about revisiting your tutorial videos. Respectfully,

[@naturenel]

You’re such a teacher. 🤩 Perfectly put. I’m on my spraying season as well. Pests have been pretty damaging. I’ve found a couple of orchids damaged from scales and mites. I have so many that I do miss some here and there furring the heavy heat. I’ll be spraying this week for sure.

[@rn4872]

Nelson I love your videos especially Physan and I think you are right to protect your investment. my suggestion though is for you to fill up the water prior to putting your physan 100% no bubble from the hose. Its not good to have fungicide contact on your hose. Love your garden.

Thank you Sebastien. I did learn that phals do well on mounts as long as the roots are rapped in the moss. I tried both ways with and without moss. The bare roots dry the plant out. I’m replanting most of my phals now in pots and taking them to my indoor terrace. They love it there. We have an extremely humid climate in Miami. We live inside a greenhouse. Our plants never go dry here. Miami keeps it green.

Physan is a good fungicide. I do,however, wear a face mask and gloves when applying. Good video. Clear and precise instructions. Guess I'll be spraying after all this tropical storm rain.

[@naturenel]

It’s always good habit to wear protective gear. It’s never really too much gear.

[@jodeming5088]

I sure hope Aldi’s still has those sprayers. Just got done bringing mine in the house. I only use 1 teaspoon per gallon, but I am going to up it and try it your way. Thanks for the rinse tip. Have a wonderful vacation. Chill out. We can wait for you to come back. Enjoy, travel safely, and have a drink for me.

[@naturenel]

Hey Jo! Hope you found the sprayer at Aldi. I always do 2 teaspoons now because Physan is not as strong or toxic as Captain Fungicide or other strong fungicides. As a preventative I find it better when upping the dosage on the Physan. And yes, rinse rinse rinse after any application. Specially when you have pets. I hardly ever use the hardcore stuff because I’m not keen on those heavy chemicals. I’m seeing how neem oil as a preventative will work on my orchids for pest. I also want to reduce the use of pesticide due to all my beautiful bees, butterflies, and dragonflies that inhabit my garden.

[@jodeming5088]

@@jodeming5088 I have not been using the neem oil yet. I have a new bottle to use. When I get back I will begin spraying with neem oil.

In India the farmers use allot of natural oils and plants to eliminate pests. They are big users of neem. I just have to figure out a way to use it effectively in my zone.

[@cosmic99]

In Canada we don’t use hard chemicals, it aloud but when don’t have major problems like you in Florida

[@naturenel]

Where I live it is a haven for every pest you can imagine. It’s really really bad. I’ve tried so many organic products and they all go to waist cause it does nothing to the pest. I even had a coconut tree get filled with white flies to the point it looked like snow. It literally happened at the blink of an eye. I had to spray with Orthene which is a very extreme pesticide. It was the only option. The whiteflies were already reaching my orchids in my areca palms. One application killed them all. But I hate to have to use it cause of the bees and butterflies. I’m looking into using neem oil again as a preventive to avoid the heavy chemicals. But in severe cases the neem oil does absolutely nothing.

[@lilibethforbes835]

I use that same sphagnum moss brand.

[@naturenel]

It’s the best!❤️

[@curly_and_cacti9927]

Hi Nelson, Just found your video on the Physan 20. I have a succulent and cacti collection and noticed a small breakout in rust fungus. I live in San Diego and we are getting a lot of rain so of course I’m not surprised that I have the breakout. I’ve never pretreated but with climate change I’m going to have to start this regimen in the future. I have a question regarding when you pre-treat plants if it rains a couple of days after you have treated should you retreat again? How often are you treating with the Physan 20 when you have not had a breakout. On the plants that have the fungus should I move to stronger treatment? Or do you think the Physan 20 will be enough. Appreciate your advice 🙏🏼

[@darleneavitabile6944]

I'm so nervous to use anything, but a group I follow said to use a systemic fungicide because one of my orchid roots looks yellow and black. Thank you for the video, wish me luck 🤞🤞🤞

Hi Nelson. U might want to research using pool algaecide. It’s sooo much cheaper. I use it without no problems.

[@halsmith2174]

Nelson, I lost a huge cymbidium to Black Rot so now am on HIGH ALERT for anything! Suggestion was made to use the Physan 20 routinely every 3 weeks (I'm in North Georgia (zone 7B). And the systemic fungicide every 6 weeks. What would you suggest? I've sprayed both 5/28. Thanks!!

[@naturenel]

Hi there Hal. I normally spray once a week for preventative during the wet season as a rule of thumb. If it’s really humid and wet constantly, I begin a cycle of every 4 day spraying. You may want to focus the fungicide mainly on cymbidiums, Agraecums, and Zygopetalums. They seem to get allot of fungus compared to other orchids. Double dose it. 2 teaspoons per gallon. Now I’m basing everything on my zone and setup. You are zone 7. Very different than mine. So I would go slow on the fungicide and see how that works. If you still see an increase on fungus, then start hitting it every 4 days for about a month.

[@halsmith2174]

Hiwzit Nelson its Jan from(Orchids in South Africa) thank you for the video wonder if i could buy physan20 in SA and that nice spagmoss. Do you have a scale and what do you use for them? I have a problem with scale on my cymbidiums🤔

[@naturenel]

Hello there Jan! You are very welcome. I loved what you guys brought to the show. Really awesome minis.😍 I usually treat my scales with Permatrol . It’s a soapy type of insecticide that is not as toxic as Orthene. That’s the strongest out there that I’ve used, but only in really bad infested plants. It’s very strong and extremely toxic. You can not spray unless properly geared up. Also if you have any animals or pets, they can get poisoned by it. So always try less toxic first and use the hard stuf in worse case scenario. I’m actually gonna start using neem oil again. The chemicals are harmful to the bees so I am trying out new alternatives.

[@coolbuster1583]

Hi I just started following you a couple of weeks ago. I went to OFE and bought permetrol and liquid ornamental vegetable flowable fungicide. Also got cal mag and liquid 15-5-15cal mag. The last 2 I was told to use together and wait 48 hours. I don’t wear protective gear but will next time. The permetrol i did 48 hours after very strong. Should I still use the sevin. I don’t have anything close to what you have. I showed Carlos the pictures and those are the products he suggested except the sevin i bought on my own. Anything you suggest I appreciate

[@naturenel]

Welcome aboard! 💚🤗💚 You geared up nicely. Carlo’s took good care of you. That’s exactly the essentials. I’ve been using Sevin allot more. I do use way more often than the heavy stuff. I will spray a spike in buds a couple times a week. This assures killing the newly hatched eggs. Also good for spider mites. Again I recommend you spray every 3 days for about 2 weeks to assure complete elimination of the pests.

[@naturenel]

Oh no! It’s 1/2 a teaspoon to a gallon of water. But even if you use a cap it should not kill them. Physan 20 is not a harsh chemical. Do you have the orchids in the sun? Sometimes that can cause leaf burn when you do the fungicide. Also only spray them early morning. Not in the afternoon. All feeding, fungicide/pesticides , and watering are done early morning. Keep me posted. For now all you can do is rinse them well to relieve it from the excess fungicide. But please do it early so that once the morning sun starts warning up, the orchids begin to dry.
