garden bugs!

All of these are beneficial bugs. Great pollinators. Ooops, wait a minute. I just looked up that pretty grasshopper. I read that grasshoppers are terribly destructive pests in vegetable gardens. He's on my basil. Maybe THAT'S who's been eating my basil. I've added slug pellets and they are not slowing the damage. I am reading there's not much you can do about grasshoppers as they are so mobile. BIRDS! come here, birds...

PS. BugGuide says the pretty grasshopper is a Scudderia. They are herbivores, but don't usually eat too much. Sounds like I shouldn't blame him.

the good, the bad and the ugly...... I am fighting garden pests

I have many crops doing great this year. At my community plot, where I have been gardening for about 7 years now, I have super potatoes, tomatoes, onions, garlic, and winter squash. Only minor problems there, including a few Colorado potato bugs that I have been controlling by hand picking and some minor squash borer damage that I'm sure the plants can outgrow. Late blight can be a problem at the large community garden with lots of tomatoes. Its been confirmed nearby (on Long Island) already,so I will start spraying my tomatoes there every 10 days with copper spray. The plants I'm growing are all late blight resistant, so fingers crossed it won't be a problem.

My new home garden has more issues, and more crops doing well. I have super greens, beets and carrots. The bok choy was amazing early in the season and snow peas are awesome. Popcorn, peppers and eggplants are coming along well. Basil is good, with only a bit of slug damage. I am spreading Sluggo and hope they will go away. The not so good are my broccoli, tomatoes and summer squash.

The broccoli problem is easy to figure out: caterpillars. I have both cabbage worms (from the white cabbage butterfly) and cross-striped cabbage worms. They showed up just as I was harvesting my early bok choy, so that crop had no worm damage. They are very hungry critters and have made a mess of my broccoli plants and are in the heads too. They are also eating my second crop of bok choy. I hand picked a few and mostly was hoping they just would go away on their own, rather than spray. But earlier this week I bought a bottle of spinosad (Captain Jack's Deadbug Spray) and gave them a dousing. I was impressed with how well it worked. The worms were all gone when I checked the plants the next day. I have since picked a few heads and they are worm-free. Spinosad is pretty strong spray and should only be used as a last resort. I hope it did not affect any of my beneficial insects.

The summer squash problem I am trying to figure out. I have rot at the blossom end of young yellow squashes. I don't know if it is a lack of pollination (I see very few bees there), or blossom end rot due to poor calcium absorption. If its the latter, the problem may be soil pH. The pH is 6.3, calcium 1440 ppm (optimum calcium range 1000-1500 ppm). I read that the optimum pH to avoid blossom end rot should be 6.5-6.8. I will try adding some lime and see if it helps. I am also planting as many flowers around the bed as I can squeeze in hoping to attract more bees in case pollination is an issue. The flowers certainly can't hurt. summer squash with rot at blossom end

The problem that concerns me most is my tomatoes. They are growing tall and spindly with curled leaves. I really hoped for a great crop of tomatoes this year. I have 24 plants, all different types of heirlooms. They do have a few tomatoes forming on the plants, but the leaf curl is severe and the plants look terrible. I am thinking it is either a tomato virus (maybe transmitted by the white flies I noticed on the plants early in the season), or root damage as from roots going down into the soil below my raised bed. The test of this lower soil showed a pH of 5.9 and very low levels of nutrients P, K, Ca and Mg. I've been fertilizing regularly in hopes this will help. Unfortunately I think its probably a virus and there's nothing I can do about it. :-( curled tomato leaves curled tomato leaves 8703

bugs on the vegetable seedlings

Most of the bugs I have seen in my garden this year have only been eating the very young seedlings and have gone away as the transplants have established themselves.

I was very disappointed by the heavy leaf miner damage to the beet seedlings.  I don't know any remedy for this, so I just ignored it. Now it seems that the new leaves are not getting the same damage. Hopefully the plants will continue to outgrow the miners.

My potatoes have a bit of flea beetle damage - not bad. This is a pretty regular problem in my garden early in the season. The flea beetles like the dry dusty weather, and the rain we are having now is probably reducing their numbers. Sometime I plant marigolds to chase them away, but I'm afraid these only look pretty and don't do a lot for the beetle problem. They look pretty and then they get covered by the vigorous potato plants.

I was surprised to see squash beetles already.  A couple weeks ago, there were striped beetles on nearly all of my baby seedlings. I gently tapped the plants to knock the beetles to the ground and then (yuck) squished them (eeu). I haven't seen any since. Fingers crossed. The photo below is a particularly hard hit plant - others are looking much better than this.

I also have some unknown pest damaging spinach and bok choy. I can't see any bugs and its eating fairly large holes in the plants. So my guess is slugs.Oh well. I know there are lots of organic solutions. I will have to look these up. (Or cheat and buy some slug pellets.)

Earlier in the season (a month ago), my broccoli was badly eaten by some pest. Entire young plants were eaten to the stem. I was thinking slugs, white cabbage worm or maybe even chipmunks. Since I didn't see any of these on the plants, I covered the patch with floating row cover. The plants are really beautiful now. I have left the cover on but the plants are starting to burst out if it. I love it when something as simple as row cover can solve a problem.
