yellow leaves at the base of my tomato plant
there are some leaves at the base of my tomato plants (right down near the soil) that are yellow and even have a twinge of brown. What could this be? My plants are well watered, healthy, and have tomatos starting to grow. is this a problem?
Also, does anyone have an official plan of how they planted/ harvested throughout the year in order to maximize your harvest? Thx!

Blight
Hi, I think that the cause of the yellow leaves on your tomatoes is called blight. It is a type of fungus that results from rain or watering splashing up from the soil and hitting the undersides of the leaves on your tomatoes. This transfers the spores from the soil to your plant. Some organic suggestions is covering the immediate space around the base of the plant with newspaper, or plastic can help to prevent the transfer. Another suggestion is rotation in the place that you plant tomatoes. Hope this helps!

Re: yellow leaves at the base of my tomato plant
I've had that happen to some of mine and I just remove the affected leaves with the nippers. We trim all of the leaves from the bottom few inches of the plants anyway as they grow.

Why do you trim the leaves? Also, do you do that for just tomatoes, or for all your plants?
Re: yellow leaves at the base of my tomato plant
My initial guess is that the leaves are just exhausted and the plant, if the rest of it is unaffected, is making enough food for new foliage and fruit. My suggestion is the same as Minnvia is to just prune them off, Also do a search of the forum for tomtoes and pruning. There is a lot of information there. Happy gardening. 

Re: yellow leaves at the base of my tomato plant
Like miinva, I cut the lower leaves off all my tomato plants once they are well established. Any leaf that is touching the ground is a potential disease vector and tomatoes benefit from good air circulation - especially in areas where it's hot and humid (like my backyard in Texas).
Re: yellow leaves at the base of my tomato plant
Hi)I have ny tomatoes in a pot and I have the same problems. Just the leaves at the bottom is brown/yellow.
I think I am going to snip the bottom leaves off as well. They are otherwise health except the bottom leaves.

Re: yellow leaves at the base of my tomato plant
I've been told that yellowing of the base leaves is normal..they're just getting old and tired. However, I found a website that addresses an all-over yellowing of leaves:
http://mgonline.com/articles/yellow_leaves.aspx
Here's a summary that the website provides under "proper feeding":
http://mgonline.com/articles/yellow_leaves.aspx
Here's a summary that the website provides under "proper feeding":
Nitrogen | Overall yellow with no green veins |
Magnesium | Yellow between veins, looks somewhat like iron deficiency |
Boron | New leaves are smaller, edges curl and are thicker |
Potassium | Browning of older leaves, edges dying, leaf crinkling and splotching |
Manganese | Mottling of new leaves with checkering between veins |
Iron | Yellowing of all but the veins |
Sulfur | Lack of pigment in all parts of new leaves |
