Heat! (I'm Too Hot to Keep My Leaves)

An increase in heat to high levels or a sudden "shock" of a severely hot day can trigger leaf yellowing and drop.  Many times the leaves will drop very quickly with only slight yellowing.

This "yellowing of leaves" is a simple survival reaction by the plant that allows it to conserve moisture.  Wilting and scorching can also present itself as further effects of intense heat.

For indoor grows, this is commonly from placement or growth too near the lights.  This is especially true of High Intensity Discharge (HID) lighti9ng systems which generate significant heat.  A few days of strong growth and the upper leaves may be well into the 130 degree plus range of these bulbs.

For outdoor plants, consider the location in relation to reflective items or areas that store and contain heat such as sunken beds, areas around sheds and buildings, or near reflective surfaces and asphalt.

Solutions for both of these factors usually involves moving the plant or providing shade.  I'll cover some shade recipes and ideas in the future.

Some simple steps for avoiding heat injuries to your plants......

Move the plants away from the culprit (duh!).

Add additional soil to lower the overall plant temperature.

Add shading.

Keep plants at least 8-12 inches below HID bulbs and at least 2-3  inches from LED, and T5 and T8 bulbs.

Move the pants to full or partial shade if the type requires that environment.  No sense in killing a plant that has no business in the sun!


  1. Hello –

    My name is Eleni and I’m the marketing coordinator for SimGar – The Simple Garden. Our company’s owner and engineers have developed a container gardening system that combines the best practices of both traditional soil and hydroponic technology. It's an ideal solution for growing organically in small spaces — or even for advanced gardeners to hone their cloning and seed starting skills in a controlled, consistent environment. We’ve been testing our prototypes for over two years and just this spring launched our production version for sale online and locally (we’re in Bradenton, Florida). I was hoping you might be interested in testing SimGar for review in your publication. Please let me know and I can get one sent to you ASAP! Thank you for your consideration.

  2. Thanks for the tips! It may sound like a "duh" to you, but as someone new to plants, I need all the help I can get. I'm never sure if I'm going to to do the wrong thing and accidentally kill them. I'll watch out for my hanging plants this summer.

  3. My mom always tried her best to take care of the plants in the yard. We would have special assignments that she had us when the weather would go extreme either hot or cold. Sometimes I thought she was crazy, but it helped the plants survive.

  4. I guess that really makes sense that an excess amount of heat would kill your plant. I have recently gotten very interested in using hydroponics in order to help my plants grow. I'm going to have to move a couple of my plants to keep them from completely getting way too hot.

  7. Unfortunately there are a lot of AIDS/Herpes denials on Herbal cures still out there. I did research on them after I was tested HIV/Herpes positive I was so worried am I going to die soon. I continue my search again on herbal remedy for Std, then I found lots of testimony on how Dr Itua Herbal Medicine Cured HIV/Aids, Herpes Virus,Copd, Hepatitis, Diabetes, On websites sharing their testimonies, which made much more sense to me. All the authors pronounce Dr Itua As a man with Good Heart, I pick interest in their testimonies and I contact him about my situation then he gave me procedure how it works, I proceed after one week he courier his Herbal Medicine to me and instruct me on how to drink it for two weeks to cure. I receive His Herbal Medicine so I drank it for two weeks as I was told then after 2 days I go for a test I found out I was cured from HIV/Aids & Herpes Virus, I pay homage to him 2 months ago to his country to celebrate with him on his African festival which he told me it usually happens every year. I know there are lots of (HIV)/Aids&Herpes Virus denials of Herbal Remedy movement the same few doctors and they represent a very small faction of the community. I could have died because I refused Natural Herbs Cures for so long, but luckily, by the grace of God I am alive to tell my story.
