Now Is The Time for Natural Weed Control!

Concern Weed Prevention Plus Concern Weed Prevention Plus prevents annual weeds from growing in flower and vegetable beds, around trees and shrubs and lawns for 4 -6 weeks. Reapply as needed. Weed Prevention Plus is 100% natural corn gluten. Garden Weed Preventer prevents new weeds from growing but does not kill existing weeds. Corn Gluten contains a naturally occuring substance which inhibits the growth of the seed's tiny feeder roots. This causes the weed seedlings to die before their roots ever have a chance to become established. Remember, this natural chemical barrier will also prevent desired seeds from developing also, so take care when planting flower and vegetable seeds. Do not use on grass that has been recently seeded as it may inhibit the germination of the new seeds. Weed Prevention Plus is safe for people, pets and wildlife.

Persistence is key to using Corn Gluten effectively. The more years you use corn gluten, the better weed control it exhibits. Corn Gluten is also a good natural source of Nitrogen, which is great for helping to green up your plants. Corn Gluten can also be used with mulch for even better weed control. Apply the Corn Gluten after you put the mulch down to help prevent weeds from germinating in the mulch.

It's Easier to Prevent Disease Now,
Than to Cure it Later!

Fung-onil FungicideFungonil - A good all-purpose fungicide that is usable on a wide variety of plants including edibles and ornamentals. Fungonil controls anthracnose, black spot, blights, mildew, rust and other diseases.

Infuse Systemic FungicideInfuse - A good systemic fungicide (the plant absorbs the ingredients and protection comes from the inside out), that works to control powdery mildew, rust, anthracnose (on Dogwoods) black spot and more. Because it is a systemic, you do not want to use it on edibles. Infuse works well in our climate because once the plant takes it in, it can not be washed off by our rains.

Liquid Copper Fungicide Liquid Copper - A great all natural fungicide that can be used in organic gardening. Copper is useable on a wide variety of plants including edibles. It's great to use on plants that are susceptible to blights like Japanese Maples, Dogwood, and Lilacs, and also helps to control powdery mildew and black spot.

Seranade organic bio-fungicide Serenade Garden Fungicide - An organic bio-fungicide containing Bacillus subtillis QST 713 for use on a wide variety of food crops, vegetables, roses, flowers, ornamentals and lawns. Serenade specifically targets fungi and bacteria that cause scab, grey mold, powdery mildew, sour rot, downy mildew, and early leaf spot, early blight, late blight, bacterial spot, and others. Can safely be applied up to and including the day of harvest, OMRI listed for organic growing. Non-toxic to beneficial insects.

Preventing Diseases: Whenever possible, it is always a good idea to remove severely affected foliage from a plant to help prevent the spread of a disease. It's also a good idea to spray the ground around the affected plant and destroy any old diseased leaves to prevent further spreading or contamination. If you're unsure whether you need to spray, or which spray would work best for your particular situation, bring in several samples of your plant problem to our Information Counter, and our staff will help you pick just the right solution for you.
