It seems like it’s been a tougher season than normal for our tomatoes. First they got a late start because of the cold wet spring. Then we had a blast of heat just when they were blooming, causing the flowers to fall off. Now insects are attacking any tomatoes that have made it this far.
In one of my gardens, well over half of my tomatoes have tomato fruit worm damage. This is the same insect that bores into ears of sweet corn and other vegetables.
On tomatoes the damage shows up as holes or depressions that are clearly caused by something eating them. Tomatoes can look fine one day, then bam! holes in them the next. Often the worms tunnel into the fruit and leave behind frass –worm poo — if nothing is done to stop them.
The problem is you can’t find who doing the eating. You might suspect bird pecking or mice bites or even tomato horn worm damage. Tomato fruit worms are hard to find. I saw one today on a plant and by the time I retrieved my phone to take a picture for you it was gone, or at least I couldn’t find it again.
Holes chewed in the tomato fruit are a passageway for fungus to enter potentially causing serious fruit rot. When the holes are new, you can just cut away the damaged portion and still use the rest of the tomato.
About the only way you can control these critters once they found your garden is to spray an insecticide. I prefer to use the biological insecticide BT since it will not harm pollinators. Other insecticides will control them too.
If you are seeing symptoms of tomato fruit worm on your tomatoes, I suggest getting them under control ASAP before they do any more damage.
Gardeners are fortunate to have the opportunity to grow the freshest and highest quality vegetables. Even now when organic produce is widely available, it’s no match for home grown.
When it comes to their own produce, most gardeners disregard one major criterion that defines quality ; that is appearance. Even ahead of taste, nutrition or freshness, appearance is still what matters most to shoppers. You really can’t blame folks for judging produce by how it looks, how else would you know if there was anything wrong with it? You could smell it, squeeze it or knock on it to hear how it sounds I suppose. Over 30 percent of food is wasted each year and much of that waste is because something doesn’t look perfect.
Gardeners on the other know exactly how their produce was grown because they did it themselves. So generally, appearance is less likely to be a factor in judging their produce. For example, some heirloom tomatoes are very prone to cracking or splitting. Selling blemished tomatoes like that would completely out of the question in a produce department and for good reason. Cracks and splits and other kinds of blemishes provide an entry for microorganisms to enter into the fruit. But if a gardener grew it, he would know that some types of tomatoes crack and wouldn’t worry about it. Most likely it would go from the tomato vine directly to the table reducing the chance of spoilage.
Carrots are prone to cosmetic damage too. Any number of things can cause a carrot to become misshapen such as a virus disease, insects, nematodes, soil moisture, soil texture, inadequately prepared soil, a pebble in the soil, even a tiny granule of fertilizer or who knows what else. So many carrots are deformed in a typical field that farmers had to develop a new use for them. They invented baby carrots. Those bagged baby carrots are cut and shaped from crooked carrots that otherwise would end up being thrown away.
A gardener knows most of the time there is nothing wrong with a misshapen carrot, there are some exceptions. I met a new gardener the other day who was digging carrots and tossed most of his crop into the compost because they were not perfectly carrot shaped. There was no convincing this person otherwise.
I eat all kinds of damaged, deformed, blemish and bruised produce from my garden that I would never pay money for at a grocery store or farmer’s market. I trim around the unusable parts like most gardeners do. The trimmings and any produce that is too far gone gets fed to the chickens. The hens in turn use the nutrition from those garden scraps to produce eggs. With their help, my food waste percentage is close to zero.
Powdery mildew is a serious fungal disease of cucumbers and other related plants. It can completely wipe out an entire crop in a garden if nothing is done to control it. Regular rains, warm temperatures and high humidities this season have come together to make ideal conditions for powdery mildew development.
The standard method of battling this disease is applying fungicides of one type or another. Some are chemical, others are plant derived and there’s even bacterial fungicides. The drawback to each of these fungicides is that you have to apply them early when the plants are young and continue using them through the rest of the season. But there is another way.
Recently I had a chance to compare cucumber plants growing in two nearby gardens. Neither garden had any fungicide applied to them.
In the first garden, the gardener is growing a standard, run-of-the-mill variety of cucumber obtained from a garden department somewhere. The plants in that garden were nearly overwhelmed by mildew.
In the second garden, the cucumbers show little sign of mildew. That gardener opted to grow a mildew resistant variety from seed that he sowed directly in the soil.
The difference between the two crops is very impressive. If you are one of those gardeners who have given up on growing cucumbers and don’t like to spray fungicides, then planting resistant varieties is the way to go. Really, it’s something every gardener should look for when choosing cucumber seeds. Make a note of it in your garden journal as reminder for next year.
