Here is a link to pictures of my tomato's. I was wondering if the brown
leafs are normal or if I am doing something wrong. Maybe they are the
determinate and starting to die?
An important clue is that most of the damage occurs near the bottom
where there is more moisture and less circulation of air.
You can help by thinning out the foliage and letting your plants
breathe and air circulate.
And NEVER wet the ground under the plant. You want the soil under
the plant to be completely dry at all times. You can do this with a
good dry layered mulch. To water the plants, use a buried bottle
such as a milk jug with holes punched in the bottom.
You mean you can't direct the rain around the plants and into the
According to the Texas A&M site, it looks like early blight. I
usually get some on my tomato plants, but it doesn't usually kill
them. Spray with a copper-based fungicide, according to Rodale's
"Garden Problem Solver."
Early blight seems to be selective. Some of my tomatoes that are
thick close to the ground show no signs of it and some of the ones
that are fairly thin and off the ground do have it. BTW we use soaker
hoses that are covered with grass clipping.
"Moral indignation is in most cases two percent moral,
I agree with HomerS. I get some of this every year.
If it were my garden, I wouldn't be concerned right now.
Thin out the underfoliage, the brown stuff in particular.
When I do this I wash my hands between thinnings/cleanings just in case
it is something that I don't want to spread to another plant.
Your beds/garden look nice.
I agree. I don't have the faintest idea what this is but they are all
lower leaves. I would figure that they have done their thing and not
worry about it. The crop looks good. The crown looks good. I'd
Coloribus gustibus non disputatum (mostly)
That's my experience too. Usually I scratch my head, wonder what is
going on, maybe water a bit (if I haven't been), and basically ignore
Can't promise that always works, or even is the best approach, but it
has worked for me.
If drying out and thinning doesn't cure it, may be something else. Too soon
to say so far. There are 2 common afflictions to tomatoes that start by
producing the symptoms of dead leaves starting at the bottom of the plant.
The worst is s virus that's actually in the soil. No cure. Plant something
else. Or leave unplanted for a few years. No, not kidding.
Actully, you need to start new plants that have NOT been exposed to
the disease. Then hit them with your fungicide on a schedule and
again when it rains for more than a brief spell. Several days of
extremely humid weather can spread the disease much more rapidly.
I'm pretty sure it's fungal damage- probably early blight. Good air
circulation and fungicides are the way to go. Daconil is good, neem oil
will work, as will sulfur. Copper's not bad, but it's better for
prevention (or if you catch it early).
I'm not sure about not wetting the soil just below the plant (that's how
I water!), but I do know that moisture on the leaves helps the fungus
I've had an impossible time finding Daconil. The local Agway, who has never
steered me wrong before, claims it has been discontinued and replaced with a
product called Funginil. Anyone know anything about this?
