So far, so good-Outdoors gardens

Multiple gardens with variety of flowers & mint (trying to keep pests away). It has vermiculite (little white styro looking specks) that aerate the soil. When dry, it's light and fluffy, when wet, seems to hold the water around plant. So far, so good.

I recently tried Member's Mark Potting Mix for my indoor and outdoor container plants, and I am incredibly impressed with the results. The built-in moisture management makes it so much easier to maintain an even watering schedule without worrying about over-saturating the roots. I also love that it feeds my plants for up to 6 months, saving me the extra time and money I'd usually spend on separate fertilizers. Overall, it's a high-quality, low-maintenance soil mix that has kept my flowers looking vibrant and healthy.

The potting soil was easy to use in my garden. The mixture has all the nutrients necessary to keep my flowers in great shape for the season. The mixture even has a wetting agent to help apply even moisture when I water the plants. I would certainly recommend it for all your gardening needs.
