Dear Frank,
Some of the most frequent questions we get at EarthBox have to do with growing media. There have been many conversations on the Forum about potting mix vs. potting soil, and we thought we'd take this opportunity to specify the growing medium required for best results.
We've found that the best potting media can have different names, depending on the geographic region of the country. We call it potting mix, which is the term most often used in the Northeast. In the West it's often known as potting soil, even though it doesn't contain any soil at all. Potting mix in the western half of the country is a product that you mix into the soil when planting trees or landscape plants, which makes it unsuitable for EarthBox gardening.
The point is, depending on where you live, you'll be looking at bags of potting media with different names or references. The most important thing is the ingredients it contains, not what it's called.
Read the label carefully, and look for a mix containing large amounts of organic matter such as peat moss, bark fines, or coir (coconut fiber), along with either vermiculite or perlite. Avoid any medium that contains soil, rock or clay, or any products described as "partially composted," or a "byproduct."
After extensive testing, we recently determined that a growing medium that boasts "moisture control" or "water grabbing crystals" is okay to use. Try to avoid a potting mix that contains fertilizer for a full year's feeding; but fertilizers rated for a season or a three-month time release are acceptable, especially if they're water-soluble. We found the amount of fertilizer to be minimal.
In general, any growing medium that's labeled for container gardens, hanging baskets or seed starting is well suited for EarthBox gardening. You'llåÊfind that an appropriate EarthBox growing medium has a much lighter weight than soil.
Many garden centers and chain stores will have their own mixes, and in some cases their own brands (i.e. Lowe's Professional Potting Mix). Below are some national and regional brands of potting mixes that are okay to use. This is by no means an exhaustive list, but rather a general guide.

- Pro-mix BX
- Pro-mix numerous other formulas
- Jungle-Growth

Good Bugs
Though it isn't spring yet in most areas of the country, it's not too soon for you to start thinking about and planning your garden. One important but often neglected aspect of gardening is enlisting the help of beneficial insects. There are many helpful bugs that will keep the bad bugs at bay and help protect your produce.
You can find out who they are, what they look like, and where to find them in the Tips and Tricks section of the Forum. Just visit the "Good Bugs"åÊpost.
Grangetto's Farm and Garden Supply
At EarthBox, we value our partnerships with our authorized retailers. There are nurseries and garden centers throughout the country that carry our systems; some even offer seminars and workshops on getting the most out of your EarthBox.

This month, we salute Grangetto's Farm and Garden Supply in San Diego County, California. For more than 50 years, Grangetto's has been supplying San Diego's North County gardeners and growers with the products they need, from pest control to seed and sod. This family-owned and operated business began as a supplier of crop oils and fertilizers, serving the agricultural community.
The Grangettos have since expanded their product line to include irrigation products and materials needed by golf courses, municipalities, professional landscape maintenance companies, and do-it-yourself gardeners. Among other things, they proudly offer EarthBox products to their customers.
The Grangetto brothers were raised on the family avocado ranch, and bring real-world production experience to their customers. Eddie develops custom fertilizer programs for avocados and citrus growers, while Kevin works with nursery and landscape customers. Both are licensed PCAs (Pest Control Advisors) and CCAs (Certified Crop Advisors). Being involved in these professional organizations allows them to stay on top of the latest technology available for their growers.
According to Kevin Grangetto (pictured above with his father), "We want to continue to look at our markets and make the necessary changes to satisfy our customers."

My Lettuce
"I received some great answers to my questions here last spring. Encouraged, I bought six EarthBoxes. And you were all right -- it was the best gardening decision I've ever made!
"Those six boxes did better than entire gardens I have had in the past. I had more space in those situations, but poor soil. Likewise, they did many times better than other container gardens I've had, which always dry out too quickly or rely on containers that are too small.
"We grew lettuce and broccoli in the spring, and we could not keep up with the lettuce.
"Later in the summer, we had cucumbers, tomatoes, eggplant, and peppers. The plants were HUGE...so large that when I pulled them out at the end of the year, the root balls had totally filled the EarthBoxes. Other times I've gardened, the root systems were wimpy.
"We had more tomatoes than we could eat. I had eight plants: four produced poorly thanks to blossom end rot (though the vines were beautiful), but the other four went crazy!
