Using roundup after seeding and before germination

I sprayed area with Roundup before sowing Zinnia seeds and would like to spray again before the seeds germinate. Will Roundup hurt the seeds? Does Roundup stick to seeds and then kill the emerging seedlings?

Does preem kill grassas growing out of ponds

I would not use Preen in your pond. Preen is a pre-emergent and needs to tie up in the top 2" of your soil. It does not kill existing grasses and weeds, only the germinating seed as the meristem evolves. Use a product specifically designed for aquatic use.

What does preen do for water plants

Absolutely nothing. Preen is a pre-emergent type product that prevents the germination of seeds buried in the soil. Once the plant is actively growing Preen has no effect. In fact, if your using Preen-Green you're actually aiding to the plants growth. Extreme caution should be used when placing any chemicals into a water source.

Sprayed Roundup Pro at 2oz/gal on a field today. Will a week be long enough to waite prior to tilling and seeding with fall clover?

Shouldn't be any problem, especially if it has rained during the period. It is strictly a contact herbicide so if it's growing under the ground at application it won't get it.

I have treated the area with roundup for about a 70% kill rate. A friend just mowed over the area. Will this impact the ongoing kill, and do I need to spray the area again?

When was the field mowed after spraying? If it was after three days, then the plants that were treated will die off. You probably should plan to retreat the areas that weren't killed after those plants are growing again. (It will take a few days depending on moisture and other conditions.)

In general, you can spray any missed plants 7 days after the first treatment. Then mow or seed the area 3 days after the second treatment.

If the field was mowed prior to the three days after the first treatment, retreat the entire area after the new growth begins.

For specific details, read the label for your Roundup product. Scotts has the label at the bottom of their product pages. All of the Scotts Roundup products are listed here:;jsessionid=64F09279DC15FE8877450FE65C85C38E?itemId=cat50096&navAction=jump . Select the specific one you used and click on the View Product details link. Then click on the View Label link. For example the label for the Roundup RTU (ready to use) Pump and Go Spray formulation is here: .

I hope this helps.

How long do I need to wait to reseed / sod lawn after applying roundup?

If you use Roundup or equivalent (do not use the long-acting product with a pre-emergent). Then you can reseed three days after the treatment. Do check the label for your specific product for any directions that differ for the reseeding schedule.

Some specific treatment limits: First some lawns will require two treatments with Roundup before reseeding (or planting sod). So wait 7 days after the first application to identify any green (growing) spots and then retreat. After all existing lawn grasses and weeds have been treated, you can rake the area and then put down sod or grass seed 3 days after application.

Second: for best results the plants treated with Roundup need to get rain or irrigation a few days before the application and 2-3 days after the application. (This is true if the soil is dry when you are getting ready to plant.)

I hope this helps.

I recently used ROUNDUP on a lawn The product did its job, the weeds are gone, so is some of the grass near the spray. It has not rained since the spay went on - maybe 10 - 12 days. How can I restore the...

Your grass is probably dead as well. Roundup is a non selective herbicide and will kill anything green. So take care when applying. Even green stems of young trees. Shield from spray when spraying. The best is to plant new grass. Roundup stays active in the soil for around two weeks despite what Monsanto says so add new topsoil when laying new runners or a new block of grass. Rain is no issue except within 6 hours of treatment. You can water the lawn with no problem now. Good luck and take care-Roundup is a poison that does affect our hormonal balances especially women.

When can I plant grass after using Roundup?

You can plant or replant as soon as the weeds you sprayed are dead. Roundup is deactivated upon contact with the soil, it only affects the plant material sprayed.

How to propagate a calamansi seeds?

There should be no particular problem. Just sow them about 1 inch (25mm) deep in small pots of seed compost. Germination will take 14-21 days at 75F (24C). Transfer to larger containers of freely-draining soil as they grow.
