FAQs

What does fertilizer do?

Similar to the way humans use multi-vitamins to supplement our diets, plants use fertilizers to aid their growth and keep them healthy. Fertilizer is an additive that supplies both indoor and outdoor plants with the nutrients they love. Potassium, phosphorus, and nitrogen are common ingredients in fertilizers that help plants grow bigger, faster, and bear more produce.

But helping your plants grow big and strong isn't the only thing fertilizer can do, and there are plenty of fertilizers and lawn care products that can help get rid of weeds without chemicals. You'll also find fungicides that protect your plants against fungus, mold, mildew, and rot — problems with which many indoor plant owners are woefully familiar. And for folks who are in a battle with pesky pests on their plants, non-chemical insecticides are a great way to keep the bugs away without the potentially harmful ingredients conventional insecticides are known for.


How do I fertilize my plants?

So, you've got your chosen fertilizers and lawn care products — now what? How you fertilize your plants depends on what type of fertilizer you use and how many plants you plan to fertilize. Liquid fertilizers generally need to be diluted before they're poured or sprayed on your plants, and you can achieve different results when you spray directly onto the leaves vs. saturating the soil with a fertilizer.

When in doubt, read the directions. You'll get the best results from your lawn care items if you read the manufacturer's directions before you use a fertilizer on any of your plants. The directions will give you dilution ratios, proper application methods, and tell you how frequently you should use the product on your plants.


What is compost, and how does it differ from fertilizer?

When you read about fertilizers, you'll often come across articles and blogs that talk about using compost as a natural fertilizer. Compost is made from food and plant waste that decomposes into a dark brown material that looks like super fluffy soil. It's rich in plant-loving nutrients like nitrogen, phosphorus, and potassium that'll help your garden blossom and your houseplants thrive.

Compost is used as a supplement in garden beds and potted plants. Mix one to two inches of compost to the top three to five inches of your pots or garden beds, and pour a small handful into the holes you create for your plants. You can learn how to compost at home or buy pre-made compost that's ready for your garden.
