yellow spots on tomato leaves

Posted: 13/07/2012 at 15:54

Yes, that's necrosis, dead tissue. It can be nothing to worry about in terms of disease. Fertiliser burn can cause it, and sunburn (though probably not in your case!)

Are the spots on the top or underside of the leaves? And where are the leaves on the plant? And, last question, is there any sign of a darker spot forming in the middle of the current spot?

Do the spots look like this?

joanna, can you post a photo? It's always easier if we can see the probem. Doesn't guarantee a diagnosis, but it helps. Are the spots actually yellow? Or a pale brown/fawn, as in necrotic (dead) leaf tissue?

And when you say the light levels are low, how much sunlight are the plants getting?

How often are you watering?

Lack of sunlight will certainly hinder their development. To perform at their absolute best, tomato plants need 6 to 8 hours a day of sunlight. They will perform - produce - with less but the performance drops as the hours do.

Passion fruit?

Exactly the question I asked one of the locals here when I was thinking of planting one. They won't hurt you, she said, but they're not very nice. I planted a vine. In the ground. And regretted it. It took over, not only spreading like the plague, but also popping up out of the ground up to 20 yards away. I thought I'd dug all of it out last year. This year it's raring its head again.

Never again in the ground. In a container, perhaps, because the flowers are lovely.

The bottom line with feeding toms is that that they're not "hungry" plants. You'll see it said around the internet that they are but it's more of the misinformation that floats around the ether.

Container plants need more food than plants in the ground for an obvious reason. Every time you water a container plant you leach out some of the nutrients. They dribble out the drainage hole in the bottom of the container with the excess water. They need to be replenished.

The same doesn't apply to plants growing outdoors in limitless soil. Those nutrients stay in the soil - not forever, obviously, but they're present for the roots to access until they're exhausted and that can take months. Bearing in mind, also, that decent soil has a whole nutrient supply of its own to offer the plant.

So given that toms aren't "hungry" in the first place, you could safely feed container plants maybe once a month. Certainly not once a week. The roots would barely get a rest from the nutrients before more arrive. The plant doesn't need that, and, ultimately, it does more harm than good. There's an old tomato adage that more toms are killed by over-feeding than by neglect.

Most serious growers only feed their outdoor toms three times in a season. First, a week or so after planting; second, when the first fruit starts to set; third, late in the season to replenish the soil for the plants that are, by then, starting to tire. This presupposes decent soil in the first place and yours is more than decent.

Only you can determine, by observation, the container plants' water needs. Were the plants showing any signs of distress? Had the mix dried out completely? Anyway, four days sounds reasonable and far preferable to every day. A "good soak" means exactly that. Saturating a dry - not still damp - mix until water trickles out the bottom of the container.

One of the advantages of growing toms outdoors in the garden is that you can drive the roots down deep into the soil - both away from the warmth/heat of the surface, and deep enough to access the soil's inherent goodness. Infrequent but very deep watering is the way to go outside. I'm now watering mine - about 10 hours a day of baking Tuscan sun peaking in the high-30sC - very very deeply every three days.

You'd have to have the crook leaves tested to determine exactly what happened. Plants weakened in any way - by a deficiency, by over-feeding or over-watering - are more vulnerable to disease than plants healthy in themselves. As in humans, lowered resistance is an invitation to disease.

My guess is that the over-feeding and over-watering, combined with a possible deficiency, left the plant vulnerable to a disease that's very very common in greenhouses. You're heading in the right direction in terms of working against it happening again.



Chillies problem

Cut back on the watering. Like tomatoes, chillies react against too much water. Curling of the top leaves is a classic symptom. Let the mix in the container dry out between waterings.

Passion Fruit Vine

It's probably unlikely that the slugs and snails killed the plant. If you haven't already disposed of the brown stick, pull it up and have a look at the roots.

Is/was it a passion fruit vine or passion flower vine?

Talkback: How to collect and save seeds

can i take the seeds out of a pepper and grow them

Yes, but the peppers they produce will depend on whether the parent fruit is a hybrid or pure variety. If a hybrid, you will end up with a version of the parent fruit. If a pure variety, provided it wasn't cross-pollinated, you will end up with the same fruit.
