Spring is a time when many seeds are germinating.  This is a good time to apply a pre-emergent. Pre-emergents prevent seeds from growing - any seeds so don't use in a place where you wil be planting seeds within the next few months. Pre-emergents can reduce weeds in lawns, flower beds, and other parts of your landscape.  Corn gluten meal is a natural pre-emergent.  Left over from corn syrup processing it looks similar to corn meal and doesn't have the precautions of synthetic pre-emergents.   Use Spring and Fall for the best long term control of weeds. 

To reduce existing weeds check Garden Care Tips and Lawn Care Tips. Also, a fantastic hand weeder is the Weed Hound.  Full strength white vinegar can be sprayed on weeds to kill them.  Vinegar works even better if a few drops of clove oil are added.  They can be purchased already in this form so you don't have to mix your own. Weed killers work best when the temperature is above 60 F and should not be used when the temperture is above 90 F.  I would not recommend using any synthetic herbicides.

A new product from Gardens Alive is designed to kill lawn weeds without harming the grass.  I look forward to trying it soon.

Spring is a great time to help control pests on fruit trees and roses.  Some pests such as scale overwinter on woody plants and can be killed before they become more active and spread.  Horticultural oil spray is best used in early spring but if you have not yet used it find one that can be used after your plants have leafed out.   Some can be used anytime before the temperature reaches 85 F.  Spray the entire tree or shrub, coating all the trunk and branches.  Avoid spraying when bees are present because it can kill them also.  Oil spray kills by suffication so it only kills what is present.
