I prepared my bed yesterday (so sore I can barely type). In doing so I found numerous grubs. I am not really surprised because my lawn is a mess and I don't use chemicals.
I have applied milky spore twice and will do so again in August. I am worried that the grubs will destroy the vegetables in this new bed. Does anyone know if they are a problem in vegetable beds? And if they are, what can I do organically to help?
I'm not sure what you mean by numerous but I believe you will probably be OK with what you are doing.
University tests have shown that it may take 2 to 3 years for milky spore to build up enough concentration to be effective and even after that there is questions on its overall efficacy. http://ohioline.osu.edu/hyg-fact/2000/2001.html
I have had a lot of grubs but never so many that I worry. I'm satisfied with tilling them up and disposing of them. (if you have chickens they'll gladly gobble them up for you)
Someone with more experience with organic treatments may chime in, but I think it is cheaper to chop 'em up.
When I see Japanese beetle grubs I squish 'em - unless my dog sees them first - she eats them! I suspect she also digs them up when I'm not looking, 'cause I find little holes here and there around the garden.
I guess that's an "organic" way to get of them - right? LOL
I haven't had issues with grubs damaging my vegetables. Generally by the time my garden is in full swing the grubs have hatched into full-grown beetles. The adults sure do a number on my raspberries and fruit trees, though.
I have found them while Im digging and planting my garden, I have also pulled up veggie plants that were not thriving and there were grubs attached to the roots, so yes they will eat veggie roots, but Im already seeing June bugs now so maybe they wont be an issue this year.
I do get a certain satisfaction in squishing them...this year Im battling snails for the first time. The fire ants use to take care of them, but I stopped treating for fireants and they seemed to have vanished.
Sorry, I missed that. So they do hinder the growth of all types of plants. I have not had problems with them bothering anything but root crops. So I guess the key is feed them carrots and they will leave the tomatoes alone? HA!
Yes they do appear mostly when when you turn under sod. When I grew the first crop of spuds it was in an area that had just been newly turned sod. I do not find them in the garden after the first year unless I make the garden space larger and turn under more grass.
I have found that Seven is a good treatment for Grubs. I use it in the row as powder when I plant. This has worked for ants and other insects.
I would like to know if anyone has used an organic method to control grubs or even ants. That will work the first year you treat.
