When conditions are right a seed will start to grow or what?
depending on what seed your talknig about (make questions more specific)... anywho...when the seeds are in the right condition (i prefer pre germinating) they will get a whitish "tail" at the end if u say and they will gorw upwards until u see a bump in the soil.
Can you affect the germination rate of seeds by pre-rinsing them in a chemical before planting them?
yes, the process is usually called "priming"

How can you get rid of barn grass that is overtaking my sodded yard?
Best bet, I feel is just to pull it out, or spot spray with something that kills grass. If it has taken over your lawn, you may want to kill the whole yard and start over in the fall. I may have to do that with my side yard because the grass I planted this spring did not come up well in some spots. Three keys to getting rid of it is to plant plenty of seed so you have a thick bed of grass when it comes up. Water it well so the maximum amount of seeds germinate. Then, most importantly, put down a pre-emergent in the fall and again in the spring. The pre-emergent should prevent any barn grass seeds from germinating. I couldn't do this because I plan to over-seed in the fall and the pre-emergent would keep the fescue from germinating. Now I have barn grass taking over.
Will pre-emergent weed killer kill bulbs?
Pre-emergent weed killer places a thin barrier on the ground that kills the roots of little seedlings that try to sprout, effectively stopping weeds before they can grow into a plant. This has no effect on existing bulbs (which are already beneath the layer of protection), although it should stop any new bulbs from sprouting from seeds that the plant may have spread last year.
When do you apply a pre-emergent weed preventer?
When the forsythia blooms.
What are pre-emergent agents?
Herbicides used to fend off weeds
How do you control cheat grass in lawns?

Can you mix pre-emergent crabgrass control with post-emergent lawn weed control together?
No, pre-emergent crabgrass control cannot be mixed with post-emergent weed control. The two herbicides in question have different application times and treatment schedules. No weed killers should be mixed together without specific reference to such a combination on the company's website or the product's label.
What are the names of pre-emergent weed control products?
The proper phrase is "pre-emergent herbicide" and it's any herbicide used to prevent the germination and/or emergence of a viable weed species. Compounds such as trifluralin (Treflan brand), S-metolachlor (Dual II Magnum brand), pendimethalin (Prowl brand), and dimethenamid-P (Outlook brand) create a chemical barrier in the top inch or so of the soil to either stop the weed seed from germinating, or make it unable for the weed sprout to break through the soil.Always read, understand, and follow instructions on the label of any pesticide BEFORE attempting to use it!!
What are the names of pre emergent weed control products?
Pendimethalin, Trifluralin, Corn Gluten Meal
Can you get rid of portulaca?
Portulaca is not difficult to kill with many common herbicides. Check the inside label. Purslane is closely related and usually listed. I think the main problem is that both seed so much. Even if you kill the plant, there are plenty of seed in the soil to germinate & ruin your landscape. Try a pre-emergent herbicide after killing the weeds. It can keep seeds from germinating. Portulaca does root very shallow. Pulling young plants is your best way to go. Using heavy mulch or paper under mulch can help.
How do you kill chamberbitter weeds?
Digging up, mowing and mulching, and treating with herbicides are ways to kill chamberbitter weeds. The plants in question (Phyllanthus urinaria) can be dug up in the seedling stage and prevented by regular mowing and mulching. They respond to chemical treatments with pre-emergent and post-emergent weed-killers on the following basis:for lawns, pre-emergent atrazine in centipedegrass and St. Augustinegrass; isoxaben in bermudagrass, centipedegrass, St. Augustinegrass, tall fescue, zoysiagrass;for lawns, post-emergent atrazine in centipedegrass, St. Augustinegrass; dicamba, mecoprop, 2,4-D in tall bermudagrass, tall fescue, zoysiagrass as well as reduced rates in centipedegrass and St. Augustinegrass;for landscape beds, after greening-up in spring, glyphosate as a pre-emergent and -- but not among new plantings -- isoxaben as a post-emergent.
What type of weedkiller kills sandburs?
Pre-emergent and post-emergent herbicides are the types of weed killers that kill sandburs (Cenchrus spp), bunch-type, low-branching annuals and perennials of open fields and meadows and of drought-weakened turf. Pre-emergent herbicides that control crabgrass include the common names benefin, DCPA, oryzalin, oxadiazon, or simazine. Post-emergent weed killers range from the organic arsenicals DSMA or MSMA in bermudagrass lawns to imazaquin in warm-season grasses and Saint Augustine grass.
