Overview

Building a healthy garden means giving Mother Nature a little extra help. Planting the right items for the amount of sunlight a specific area gets is an important first step, but you’ll also have to occasionally water your plants to make up for dry spells.

Another way to give your garden a little boost is through the use of fertilizer. The right kind of fertilizer will provide your plants with a hefty dosage of nutrients that promote healthy growth. But not all plants need the same nutrients, so it’s important to match the fertilizer you use to the type of garden you’re trying to grow.

Home improvement expert Vicki Liston recommends conducting a soil test before purchasing your fertilizer. “Simply dumping nutrients onto a patch of land and crossing your fingers is like playing darts drunk and blindfolded — there’s a high likelihood the pointy end won’t be close to the bullseye,” says Liston, host of “On The Fly…DIY,” an award-winning show with fun project tutorials. “Most county extension centers will conduct low to no-cost soil tests that tell you the pH and nutrient levels. You can also purchase a test kit for yourself.”

Many pet owners have concerns about their furry friends ingesting fertilizer in the days following application. Although the nutrients in fertilizers are generally safe for animal consumption, your pet could get sick if your chosen fertilizer has insecticide as part of the formula. The most dangerous types of insecticides have been reduced by EPA regulations, but it’s always a good idea to keep your pets away from fertilized areas.

One major factor differentiating various fertilizers is their application. Some fertilizers come in traditional bagged form, which means you scoop the contents out and settle them into the desired area. There are also spray fertilizers, giving you a bottle you use to spray every week or two. There are also fertilizer stakes, filled with the desired nutrients that autorelease intermittently.

Buying fertilizer to help save dying plants may not be a good idea. Fertilizers will work only if the reason your plants aren’t growing is that they aren’t getting enough nutrients. Your plants may also be exposed to the wrong amount of sunlight or water, or it could simply be that your garden is too close to tree roots that are competing for growth in the same space.

Organic fertilizers have become a popular option in recent years. These fertilizers eliminate chemicals and odors for a safer way to promote plant growth. You’ll find organic fertilizers are made from natural ingredients like insect excrement, while inorganic fertilizers are manmade.
