For Japanese beetles on rose bushes, do you apply milky spore just at the base of the bush or directly on the bush as well?

As far as I am aware, the milky spore is effective against Japanese beetle grubs in the ground. The beetles you see on the rose bushes are in their adult stage. An insecticide effective agains adult Japanese beetles should be used on the bushes. Milky spore is designed to control Japenese beetle grubs in the ground, before they become adults.

You would apply the milk spore all around the base of the bush and out about 10 feet or more in sections like a grid.

Killing the beetles may seem satisfying, but will do little good long-term. They reproduce right away after emerging in early summer, so next year's beetles should be killed as grubs. The smallest bag of milky spore covers 2,500 sq ft, so you might as well spread it over as much area as you can. The grubs eat grass roots, so it's not just roses that get damaged. It may take over a year to clear up the problem, but then it will last in the soil for 10+ years. There's a seasonal product that kills grubs quickly that you might want to use until the spores are effective. Beyer is one manufacturer.

I have used a full bottle on my 12 Japanese Privets on 2 different occasions, over the past year. The suckers come up with less frequency, especially mid-trunk (I still have suckers on the bottom, but less after every treatment). My privets are still blooming and growing happily. So - I can only attest the answer to this question for Japanese Privets, and when used as directed - in that case, I see no harm to my trees. And MUCH less work for me.

can be used for any trees, respond very well for any fungus,i have powder mildow on my phlox last year,i spray twice with copper fungicide and is gone, my friend have black spot on her roses,spraying with Serenade and copper fungicide shows good result

I'm using it in an attempt to get my plumeria to bloom. My brother uses it quite successfully on his plumeria and says they are heavy feeders. Don't know about the desert rose though. I would think that anything that blooms would benefit?

The label specifically says its effective on Japanese beetles. I can't say from experience if this is true because I don't have a beetle problem.

Once black spot occurs on the leaves the plant is already infected for the season. Very difficult to do anything about it. Best advise is to use a systemic fungicide at the start of the season as well as the fungicide powders on early growth and remove all dead canes and any debris around the rose bush at the start of the season. Also do not use unclean pruners between other rose bushes during the season. Wash with the pruners with alcohol before each and every pruning episode. Essentially once it starts its very hard to stop it. Usually it does not effect flowering though. It just ends up defoliating the plant and the fungus progresses.

I'm no expert on this, but I'll put down Milky Spore any time there isn't a chance of freezing. It's probably too late to make a difference for this year's crop of beetles, but it will give you a good start on getting rid of the grubs that will become next year's beetles.

it is granules. The amount to use is based on the diameter of the tree you wish to treat. you sprinkle the granules around the base of the shrub or tree and water in. Some insects like the emerald ash borer has a specific time of year to treat.

This is designed to be applied AFTER the Japanese beetles have laid their eggs in the soil and their invasion has subsided. That is around late July in Upstate NY but may vary in your warmer climate. The IMPORTANT thing is that it gets soaked into the soil after it is put on the lawn. This means a good watering or preferably before a soaking rain. The hatching grubs will eat the spore, it'll multiply in their carcesses and multiple many times over killing successive generations of grubs.

For best germination: only cast the seeds on the surface. See planting details at http://www.seedaholic.com/lobelia-erinus-compacta-rosamond.html

It may be that I just do not get enough sun in my yard which has a lot of tree cover but mine are not very bright at all. My rose bush attracks June Bugs quite well!

To me, roses are sort of alien beings with attitude. If you have bugs, definitely spray wherever you see them. Insecticidal soap shouldn't hurt the plant. If you have powdery mildew, that's a horse of another color. (Fungus) Check online for "cures" for fungus. Might be as simple as alcohol and water in a spray bottle.

From the label it looks like the rose bushes will be tolerant, I would imagine your lillies would be tolerant too. Try not to spray directly on the plant. I often use cardboard to shield my plants from any spray. I've used this to kill grasses around my vinca, and saw no problems. You can always give Ortho a call and ask about your lillies. 800-225-2883. You should also search for "Grass b gon label" and read the full label - it is readily available, and gives a lot of information on plants and safety.

I usually use my hand or a strainer and when the wind is not blowing, sift it on my plants sparingly. Or on Ant mounds, and across driveway to keep bugs out of garage, and in windowsills to keep any little bugs from getting in. I don't usually sift this on my plants but if I need to it would be just a light dusting on the roses. I also have mixed a tablespoon into orange juice occasionally to cleanse my system. I am not one to take a lot of supplements, so I do not do this regularly like some people do. Ants, spiders and beetles do not like this stuff!! I put it around my vegie garden on the ground.

Test your soil first to see what it needs. In general this is a good product for protecting all roses from pests and fungus.Some areas will not allow its use due to runoff causing environmental problems.

I do both. I will spray around my gardens as a general deterrent and then spray directly on plants. Be careful - it will "stain" some plants - like pansies. But does work. Try the granular type too - that works a little longer - especially if you have any rain.

It could be, but it is designed to control larval bugs like Japanese beetles who lay eggs in soil after mating. The milky spore infects the resulting larvae and breaks the reproductive process. You would have to have potted plants with beetle problems that have deep soil to make it worth while applying.
