In the Garden

Pre-emergent – Preen

Application Tips

First remove any existing weeds that may be growing. Then apply Preen Garden Weed Preventer using the easy-to-use bottle with flip-top applicator-cap. When plants are dry, sprinkle the product granules on top of the soil or mulch at the rate recommended on the label. Use a rake to work the granules into the top layer of soil or mulch. Once activated by watering, it forms a weed control barrier in the top layer of soil, preventing weed seeds from germinating. Disturbance to the soil surface after activation may result in erratic weed control.

Application around established plants

For flowers, roses, herbs, ground covers, ornamental grasses, shrubs, trees, and listed vegetables at least 2-3 inches tall, sprinkle Preen Garden Weed Preventer evenly over the entire soil surface at the rate of 1 oz per 10 sq. ft. Be sure to keep granules away from plant roots and foliage. Integrate with a rake and then immediately water. Always wash or brush off stray weed preventer granules from plant foliage to avoid damage or discoloration.

Application around mulch

If using standard mulch (and not Preen Mulch with Extended Control Weed Preventer which includes weed prevention), we recommend applying Preen Garden Weed Preventer after spreading the mulch on your flower and shrub beds for best weed control. Sprinkle Preen on top of the mulch and integrate with a rake. Be sure to keep granules away from plant foliage. Immediately water this product into the mulch. Always wash or brush off stray granules from plant foliage to avoid damage or discoloration.

Weed Control in the Flower and Vegetable Garden

Manually removal of weeds by pulling or digging will work best.  Find a tool that works well for you.  Consider using the digger or trowel to loosen up the roots so that the weed may be pulled from the ground more easily.  Flor larger weeds, consider using a spade or shovel to do the same thing.  Divide the garden into segments and tackle just one segment at a time so as not to be overwhelmed by the task.  Do one segment each day until completed.

The most important consideration is to begin early in the season before the weeds get large.  Small weeds are easy to remove if you work on one segment at a time.  Large weeds will take longer to remove making the task tougher.  Start early and keep it up through the season.

Consider using a mulch to help keep the weeds down and hold moisture in the soil.  Bark mulch is easy to use, apply and maintain.  And it looks pleasing as well.  Rock mulch looks nice but requires more work to apply and maintain.  Weed barrier fabrics may be used at planting time for areas that will not be disturbed again for some time as it is sometimes difficult to cut through the fabric for future plantings.  A light layer of grass clipping will make for a good mulch in the vegetable garden.  Each week, spread another thin layer over the soil between plants.
