It is deeply impressive that you were able to shoot this in one take. No hyper-edits, no cutting out the "um"s, and that shows how confident you are that you know what you're talking about, and were well-prepared to speak on it. Kudooooossss

I've been outside taking pictures of my seedlings and posting them on reddit, trying to figure out what the problem is. This video is perfectly timed!! Thank you

I'm a first time gardener this year and you have been soooo helpful! Thank you for your craft and sharing your love of gardening.

Dude I did not realize all of your seeds are heirloom, that’s exactly what I have been looking for...great prices and free grow guides on KZfaq from Luke himself. Thanks man!

Wow, so timely! I was just asking my dad if he had any ideas for why my plants looked a little sketchy, but I'm hoping it's a bit of transplant shock and that I'll see improvement in another week or two.

Your enthusiasm is contagious. I now love gardening. Every time I need to look something up, you somehow have a video on it already! :)

Always the first channel I check when I have gardening questions! Thank you so much for all that you do for budding gardeners!

Thank you for always being such a great source of gardening knowledge for all of us! ♥️

I LOVE THAT HOODIE EVERYTIME I SEE IT! Great video, thank you for the reminder not to panic because I sometimes forget. The best you, Mrs. MI Gardener and Mini MI Gardener. 💚

Another reason: Planting summer plants too early in the spring before soil temps are warm enough. Don't be in such a hurry, and don't always believe what the back of the seed packet says!

This is my "go to" gardening channel!

Hi Luke, Excellent and timely information. Thank you. My lemon tree was getting yellow. Fertilized it and it looked much better by the same time the next day. All the best from California 💛

I love how i have watched like 50+ of your videos over the past 2 years and just realized your name is Luke. You don't introduce yourself enough! You are totally a Luke!! Love your videos! My plants are definitely in the fruit is more important than leaf cycle.

Oh wow, this was so helpful! Especially regarding the tomato plant and the adjusting new transplants. I can relax now. Thank you for sharing!

Over watering can also do this - especially evening watering - and it is probably the most common problem after shock. Many (most) plants require air at the root system during the night. Too much water can actually drown a plant. First thing I always try with yellow (not brown) leaves is cutting back the water. If root rot is involved - it will also help that. Shock - especial in newly transplanted plants - can come from any type of stress. Even a windy day on a young or newly transplanted plant. Although normally wilting is the tell tale. Just have some trust and keep caring for the plant(s). If you are a container gardener - reusing the same soil for more than one season can also do it. You can;t treat potting soil like garden soil. Potting soil gets depleted very quickly and is hard to refresh. Always use new soil each year and drop the old in your compost. Try to top off your container plants with fresh soil or compost a couple times during the season. Arg....I've typed too much for the internet!

Great video once again and perfect timing!! I am definitely going to try the fish emulsion recommendation this afternoon. Thank you so much for sharing :)

I’ve learned so much from your channel! Thank you for always making content that is clear and to the point. The way you word the info and the examples you take the time to show your viewers is always so helpful.

I have been looking for information on yellow leaves for some time now and nothing is a clear and concise as your video. I have now subscribed. Thank you for the great information

Thanks for sharing this information. We have sandy soil here so I have to feed my soil a little more often and I try to give them some compost tea throughout the growing season.

Thank you! In High School my Family moved to Farmington, MI! MI is gorgeous! Thanx for the info! Have a great week!

I know this isnt a brand new video,but thank you for making it. I found it just now and it was really helpful.

Thank you for explaining this so well. I actually felt like it made sense. I am very excited to get the garden going this year!

LUKE! so...omg, i built my raised beds ~on top~ of beauty bark, and my shallow beds have been turning very yellow (except the peas.) this is because of the nutrient exchange, eh? i didnt think it would hamper it in a negative way, but it must be. and now i know. wow. thank you. and hopefully things go positive enough for the rest of the season. 🤞🏾

Garden plants: Baby us throughout our lives or we will die.☹️ Weeds: spray me with chemicals that kill everything and We will still grow through asphalt that is 200 degrees 😐

Very happy I found you. I’ve been gardening for many years but I can always learn something. Or lots of somethings. Thanks.

Perfect timing. My Kajaris started looking bad when I transplanted them. I watered them with fish emulsion and they look worse. It’s been about two weeks since transplant but just a couple days since the fish emulsion.

Thank you very much! All of our radishes turned yellow recently so I'm very grateful for this video :)

We had so much rain spring of 2019, then a lot of my plants (especially currant bushes) were turning yellow, but the veins were still green in the leaves. Found out it was chlorosis so I gave them iron and they greened back up!

Hi, Luke! I hand pollinated my squash the other day and thought of you. 😁 I giggled and giggled and giggled.🤣

Last year, I had this problem. I did a web search for possible reasons and possible solutions. It wasn't time to add fertilizer and the plants were established. One reference indicated that the yellowing could be caused by a magnisium deficiency. The solution offered was to mix up some epsom salts in water and put it in a sprayer and spray the foliage. This helped my plants green right up. I only had to do this once during the growing season.

Thank you for explaining why our plants would turn yellow. That has happened to me and I've emailed you about this lol!!!! I have always had a passion gardening beautiful flowers. But due to a very bad back injury I stopped at 24. When this horrible virus started I knew I needed to start my own vegetable garden. So, I started watching some You Tube videos and that's when I saw you. Thank you.. you have inspired me to just do it. "Grow big or Go home" LoL..I just started one day with some seeds from Amazon, a heat mat, grow lights and lots of praying. My seedlings grew, but I felt all over the place. So I purchased your book Ive been reading your book, The Autopilot Garden. A Guide to Hands -off Gardening. Awesome, easy to understand, so informative book!! And that's where I'm at... I'm praying my vegetables will produce now lol... We'll see

Thanks again for another great, informative video! Gardening is something we need to do more of, and our worm castings help, but we definitely need to add more mulch to the gardens we have. Time to fire up the chipper! Thanks again!

I love your channel. I’ve gotten so much helpful info from you that I decided to buy your book on Amazon today. I know it will be great!

Good information, thank you! I live way down south but it’s still relevant to my gardening in lots of warm/hot weather!😁👍🏼

New follower from Holland MI! Excited to have someone here with my weather to guide me ! I’m a dummy and trying so hard - my garden looks beautiful !

Perfect timing! My lettuce just started turning yellow and I planted them a week ago. I was getting worried.

Very timely message for me. I was researching why my pea plants were yellowing. From the video it seems that they need more nitrogen. The soul I bought for their pot had a lot of un broken down organic matter in it. The rest of my garden is fine because it's got good soil. So now I know how to fix it :) thanks

I enjoy your videos greatly. They have inspired myself and my siblings (because I show them your videos ALL the time lol) to make a huge garden. So thank you for your videos and the information you provide to us :)

Ya'll have awesome customer service I had a problem with my seed order and as soon we got ahold of you the problem was fixed! It was completely my fault I'm not used to buying stuff online 😆

Thanks man! So happy you have the passion and ability to put on learning videos as these. God Bless!

ALWAYS ALWAYS ALWAYS I learn something new! Luke I never get tired of listening to you and appreciating your WEALTH of knowledge! Thanks for sharing with us! And I too love your PMA! (Positive Mental Attitude). Kristy in Missouri 😀

In a future video, would you consider addressing what percentage of your family’s food you grow yourselves, and how much total growing space you have? My house is on a plot that is 1/12 acre, and less than half of that is fit for growing. I’m trying to figure out how to optimize that space to feed my family as much as possible.

Thank you! This was very helpful. I am fairly new to gardening and was dealing with this issue just a few weeks ago. Our fix was adding blood meal, I actually have a video of this. Thanks again!

Perfect timing, for me! Thank you!

Spot on information and video Luke. This is what every Gardner needs to know. I just spoke about similar issues in my some of my latest videos too. Take care and God Bless You and the Family.

@ migardener As a new gardener, three weeks ago, I am gaining so much practical knowledge from your videos. I especially enjoyed this video because you included info that a novice would take for granted ( i.e. consider the life cycle of the plant). This is so useful for me to understand why the new leaves in the development stage, need nitrogen, if yellowing and may need phosphorus if they are yellowing at the flowering stage. Thank you.

My dude I love your channel. Dont stop creating content. Im a know it all and youve reminded me how much fun it is to learn and be wrong.

Really good video! We are experiencing yellowing leaves in our new transplants (just a few), your video gave us some good insight. Thanks!

I appreciate your sharing of the knowledge and that you keep your editing very simple.

I really needed this video, to understand the yellow and many different plants plus I have heavy clay soil and so your discussion about the sand in the clay and the compost was perfect thank you

Thanks a bunch!! I am new to vegetable gardening this year. This is a great help.

This is great information! Thank you for being such a great teacher and sharing your knowledge.

I planted okra seeds too early, thinking the warm weather was here to stay in mid-April. Since then, we've had chilly temps, light frost ( protected them with cotton sheets ), and now days of nonstop rain. My little okra seedlings (in containers, mind you) survived all that to put out yellow leaves. And then it got sunny and warm, and the leaves turned green, without me doing anything to fix it. I may get some okra, yet! I would have worried, had I not seen this video. Thanks, Luke!

Great info on the life cycle stuff! Hadn’t thought of this before!

EXCELLENT VIDEO AND INFORMATION!!! Thank you. You have such a clear, concise, and intelligent way to explain many things ( I have heard bits and pieces before), but you articulate everything in such an easy to comprehend and educate- without either oversimplifying it (that doesn't quite enlighten or offer much substance), nor without overcomplicating the discussion (with too much technical explanations that can be boring, unhelpful and too difficult to follow)! You really hit home with this video for my question of why new transplants were showing yellowing leaves; I was questioning the location, and soil arrangements I set up. I will be more patient to see how things progress. I would love to see a video explanation on homemade/DIY soil amendments that I could do if I cannot find or purchase things like fish emulsion, blood meal, compost tea, worm castings, etc. where I live in Italy. Also, I would love a video explanation on 'what the differences are between compost bins one can find to purchase' verses what you need and 'how to build your own compost bin' , as well as how to compost properly. I have seen how they are charging a fortune selling various compost bins, and I have heard contradicting information about how they are making them and advertising the process all wrong, complicating it, and charging a fortune for nothing! I would be interested to hear your expertise and opinion on it! Thank you again for the wealth of information you are putting out there, and I look forward to watching more of your videos!

Thank you. I was considering putting my used wood-chips into my composter after the season. I will. But maybe not too much.

Thank you for all the great information. Please keep up with your kindness and continue teaching us. God bless you

Thanks bro. Great video. I have a lot of clay in my raised bed. I added a bunch of compost (broken down horse manure), but was preparing myself for another failed season. You’ve given me cause for hope.

Bought your seeds and trifecta+ this year and everything is looking SO GOOD! Perennials that haven’t been doing well for years have life again due to trifecta! Will be purchasing my cool season seeds from migardener as well 🎉 So happy to see a local MI gardener making a splash nationally!

The extension office in my county has been closed since March. So I come here for gardening information and even though I'm in Florida and MIgardener is located in the north, he has given me a lot of useful advice.

You are my go to source for plant advice. Thanks.

Thank you so much! I love your channel So informative. I'm planting in containers this year and actually having a severe problem with leaf curl. I've tried everything I know. Over or under watering nitrogen, magnesium e.t.c. I'm just a novice and would appreciate any help I never had this problem when planting directly in the ground.

Love your videos and the explanations are incredible. Thanks for sharing so much information!

You have the best timing! I was just looking up why my tomatoes were turning yellow and in my subscription feed, here you are. Thanks so much for what you do! Grow big or go home!

Thank you for that fine information, always so informative and I love your videos. I wish you had gone in depth a little further about how to cure the specific issues you mentioned in this video. Please make another video showing and telling what we can do to prevent yellowing. Thank you so much.

Straight on the point. Really informative. Thanks much for this video!

This was so helpful, thank you for your expertise. 🌺🌸🌼

Awesome thank Luke I really needed this guide got this problem with my bean plants surprisingly

Luke, Heeelp!! A co-worker bought tomatoes this past weekend and discovered all the seeds inside had sprouted!!!! She said the tomato looked perfect. How can this be??? I told her I would ask my garden gurus about this phenomenon.

Thank you Luke. Really good information.

June 27th, 2021 question...I do have a lot of unbroken down material in my new soil that was put in my raised beds this year and I am finding a lot of yellowing. You said to add potassium so it will balance what is being taken from the unbroken down matter and my plants. (How much and how often do I add the potassium?) Love your channel. So much good detailed information. Very helpful.

Some warmth-loving plants will turn yellow if a sudden drop in temperature occurs. Something we have to live with here in Northern Germany. They recover when it gets warm again. Careful of too much nitrogen - it is no good for root crops.

Thanks for this informative video Luke, it's very helpful.

Well this is a very timely video I just spotted some yellowing on a few plants this morning...wish I hadn't bother spending an hour this morning doing research on the internet

There’s so much useful information in this episode.

Thank you for explaining the different reasons plants may turn yellow.

Thanks for sharing! Always lots of good info over here.😊

I have some determinate protatoes in a self wicking container. Some of the bottom leaves turned yellow and I got worried. This makes sense. TY!

Other than your own book, what other books do you recommend reading to help dive into gardening? Classes? Advice much appreciated!

You are awesome. Keep on keepin' on, brother. Cheers from the West Coast.

Thanks. I’ve been having trouble with new potted plants turning yellow and dying.

Just came in from the strawberry patch. Perfect timing!

Thank you for this video... It answered my question in multiple ways!

We've had so much rain. My tall daylilies have starting to change like that. We have clay soil here too.

Mine are turning yellow in doors as I hardening them off this week to prepare for planting.

Around November I scan the curbs for throw-away straw bales. Outstanding mulch.

Great video, thanks for the help on yellow leaves!! I can go fix my soil.

Could you do a video on fertilizer and what 5-1-1 means and when you would need different kinds?

Excellent resource! Thank you so much. Best explanation i have found!!

Thanks Luke! Great information! I love your videos!

Wow! I needed this info. thank you. talk about perfect timing. subscribed.

So I planted on thursday and it poured ALL day on Saturday. I used Biotone when I planted. Should I fertilize again now or wait? Thank you!

Thanks for all the informative replies. Makes a lot more sense, now!

Thank you! For great information and inspiration always.

Hello Luke I grow 4 tomatoes but there yellow I thought they had a magnesium deficiency so I sprayed Epsom salt 4 days ago but it didn't fix so I gave it nitrogen fertiliser but it still didn't fix the yellow but there are still young and they aren't growing bloosems yet so what could be the problem then? Thanks.

I have been watching you for a couple years now. I like your INFO and PRODUCTION. Thank you for not using MUSIC and trying to entertain us. Some of your early videos were a turn off because of the music then you updated to the one you used all the time. I like it better when it is educational and NOT ENTERTAINMENT.

This is very informative and educational! One quick question though, I’m growing my first mammoth sunflowers in a pot on my deck. We just had 2 days of thunderstorm. At one point my garden had too much water puddle in my pot that I had to drain them out. I didn’t re water because soil is still rather damp. My question is, should I add more soil over it to get the nitrogen in the soil? I use miracle gro soil. I do have a different bag of soil called gardens ape for potting soil. Your feedback would be greatly appreciated. Thanks!

Thank you so much! Always learn a lot from your videos!

Sometimes when my plants turn yellowish when it starts gotten hot . I also find I have a spider mites or aphids problem.
