fast and to the point. THANK YOU

[@MarkyMark145]

wow thx, very useful video. The last piece of advice u added with the physiological symptoms due to weather and it being fixed until conditions improve was just it.

[@mackmckenzie8479]

Just wanted to say thanks for the knowledge you share,, I also enjoy the e book on peppers

[@dontbestupid6664]

First channel I have heard about broad mites. I was never able to diagnose my tomatos until now. Thanks alot.

[@geekygreenhouse]

Happy to help!

[@ballincobalt4184]

I have leaf curl at the top of just 4 of my indeterminate tomatoes, we’ve had temps around 30 in the day with some nights around 10 with little to no rain, I’ve been watering daily, I hope I don’t have to remove them, leaves are still a nice green with visible damage, they are still producing tomatoes, so I’ll just keep a eye on them a bit more and hopefully they recover

[@Arcticdi]

Good info here and articulated well. THANKS!

[@sylviaw.1584]

This is very helpful. I did have an issue with a tomato plant grew fine and then all of a sudden the leaves grew very close together in clumps. Then they curled up after about a week and the plant died off so I removed it. The soil that I purchased was from a company (Soil3) and my other tomato plants and rest of the garden were not effected so I don't think it was the soil.. I never found out what caused it. I did spray with neem oil but it was too late.

[@nkvball808]

Might be tomato yellow leaf curl virus - did the top look like broccoli? It’s spread by white flies or aphids- there is no cure

[@joepa6106]

Neem oil can cause damage especially sprayed during sunlight hours

[@sylviaw.1584]

@@joepa6106 I only spray after the sun is down so the leaves don't burn.

[@erikutube33]

Prob the Curley top virus. I had that to. Pull it and discard immediately, there’s no solution but that. Unfortunately… 😢

[@Claybizzle]

There's a genetic component in open pollinated hybrids. Breeders try to select it out of they can because it can have negative effects on productivity.

[@dogg91702]

I have experienced my cherry toMato plant leaves curling, getting hard and leaves getting dark. This was a plant i transplanted from another bed

[@sandrarichardson2713]

Terrific video. Lots of great information. Thanks for your work to put this together. It helps. Jesus bless.

[@muddeprived]

I have 10 tomato plants in one 4x8 bed that is raised 3" out of the ground. Three of the ten plants have had leaf curl since they were 2 feet tall. They are now 6 feet tall and still have the same leaf curl but no issues with the tomatoes growing on them. They were all subjected to the same environmental stress and the same watering routines and are not affected by pests. I have tried shade cloth to reduce the amount of sun and heat but that did nothing. The plants are doing fine but I am wondering what would cause just three of the 10 to leaf curl. The leaves are curled pretty tightly that you could shove tobacco in them and smoke them lol. They are also very stiff and hard compared to the other normal growing plants. If anyone has any experience with this then please share. Thanks!

[@sueguidry4216]

I missed what flowers do you use to help your tomato plants to have very little bugs. Thank you in advance

[@geekygreenhouse]

We like to grow sweet alyssum all around our veggie garden - easy to grow from seed and self-seeds every year thereafter. Also, cosmos, zinnias, and lots of various native flowers to get a bunch of pollinator activity to your garden

[@shirojankitchen4412]

What mulch recommend for tomato? I use dried leaves is that good?

[@erikutube33]

I’m using wheat straw, for three years now.

[@ttb1513]

Concerning compost: A couple years ago I had 2 new beds that I filled primarily with compost and the tomato plants in these beds, only, curled horribly. This compost happened to be delivered hot, unexpectedly, and I had no option but to use it, immediately. Is it possible that a large amount of hot compost can cause leaf curl? The next 2 years these beds were fine, so I’m not suspecting herbicides in the compost. I had a belief at the time that it was risky to use as much hot compost as I did. If I recall correctly, other beds were top dressed with this compost and they were fine.

[@geekygreenhouse]

I imagine that hot compost can cause curling leaves, as the unfinished compost isn't yet ready for plants to use. The high temps are also a concern for plant roots which prefer to be cool. I'd do like you said and top dress if you ever have the issue again

[@ttb1513]

@@geekygreenhouse Yeah, I definitely only used the hot compost because I ended up with no other good choice. For clarity, I did let the compost cool down well prior to planting, by spreading it out, etc. Of course, letting the compost cool in a matter of hours does not let the microbe populations finish as usual.

[@fishlovme]

I see it so often that people think they need to water their plants every day. Wrong! Water them once a week and give them a good soaking. Make the plants get deeper roots. Lots of leaf curling I see is because of over watering, NOT under watering!

[@jimmyjo1375]

Water when needed not once a week or on a schedule.

[@fishlovme]

@@jimmyjo1375 my point is not to over water. Usually one inch of water a week is enough. That's a good soaking of the soil, which you can usually do once a week. But if you live in a dry climate with high temps all summer then it's probably more often.

[@geekygreenhouse]

Agreed - deep watering *less* frequently is the way to go! Bigger roots, more resilient plants 👍

[@2A_supporter]

Depends where you live and micro climate 😂

[@Sandlin22]

Watering them once a week is also wrong. Water them when their soil is dry.

[@sueguidry4216]

About how much water should i give my tomato plants snd how offen

[@geekygreenhouse]

Just try to keep the soil evenly moist, and don't water unless the soil is dry a few inches below the surface. The roots can access deeper moisture

[@MariaRodriguez-gc9jk]

I gave an aspirin shower to one of my plant that was starting to show the leaf roll and it cleared up. I have lost plants when I didn’t do anything.

[@HLBNZ]

I do this and found that boiling a 325mg. Uncoated Aspirin in 2-4 cups of water first activates the Salicylic acid better and I get better results. I mix this after boiling with water to make 1 gallon. I add 1 tsp. Ga. of Yucca extract to keep it on the leaves longer instead of soap.

[@kathyhanson7337]

Can you spray dish soap & water on all garden plants?

[@geekygreenhouse]

No, dish soap is not recommended for spraying on your plants, as it can cause harm to the leaves. If you need to use an insecticide, best to use insecticidal soap, as it is formulated differently to not damage the plant

[@tamiholloway6452]

Are the fruits of affected plants still eatable

[@geekygreenhouse]

Yes, unless it is certain diseases that affect fruits

[@tompatchak8706]

My tomatoes are huge and well watered. It’s been in the high 80s all week. If I don’t water they die, if o over water they get weird

[@MrSBGames]

Mosiac virus can be spread by smokers touching the plants as well, I have experienced thst first hand when my mother looked after my plants one year

[@geekygreenhouse]

I've heard that! Hard to come by first hand accounts of it, but good to hear it is true.

[@nobodyreally]

My friends sister has a farm and anyone who smokes cigarettes is required to wear gloves before touching the plants there.

[@HyacinthSankey]

What causes tomato leaves to turn bluish instead of green?

[@aleksandarvasilev4042]

Phosphorus

[@toddburgess6792]

I am trying electroculture this season. If it works as well as they say, I won't even have to use Neem Oil or diatomaceous Earth. We shall see...

[@UNDERGROUNDHITRADIO]

its almost always overwatering which is no problem in the summer

[@garbonratslayer1387]

I'm staying late probably until mom is done.

[@lizdeal8899]

I hate thrips!! Those little bastards hurt when they bite…

[@timteevin4517]

These tomatoe vids talk about determinant and that other one but people who watch have NO IDEA what kind of plant they have. They bought at the hardware store a plant called Jumbo tomatoe. ??????

[@ladonna1902]

Did the plant have a label or tag that came with it? Sometimes the tag will say whether it's determinate or indeterminate. Also if the label/tag says it will require staking or caging as they grow, then it's likely indeterminate. If the label/tag says container garden friendly, it's likely determinate and will only grow to a certain size.

[@carlstrom3898]

Can you use hydrogen peroxide to sterilize your tools?

[@geekygreenhouse]

Yes, but it isn't as quick to kill pathogens as something like rubbing alcohol is.

[@kelrune]

with in 5 seconds, you said watering is bad. over, under, and watering causes curl. work on your delivery. with that your saing dont WATER your tomatoes. what about starting with how to water, NOT TELL US WHY WE CANT WATER, OR OVER WATER, UNDER WATER.
