Sown seeds need plenty of moisture. The water content of the seed needs to be about 70% for a chemical process to start. MENDOZA: Frass does seem to have a certain added benefit. At about 10% mixture, it seems to add enough nutrients to the soil but also not add too many. Seed coatings (Testa) often need soaking to soften or scratching (scarification) to help it to break open and germinate. In the wild this would happen with weathering or animal interference. MENDOZA: To maybe not be Mark Watney - I'd prefer not to get stranded on Mars - but to be an archetype, inspiring people to learn more, and you really do a lot with available resources. SHAPIRO: Mendoza recently presented his experiment and initial findings at the Entomological Society of America's 2023 conference.

Seeds have a shelf life. Use them as soon as possible to increase their chance of growth. However, make sure the germination environment is suitable for the plant to grow in.MENDOZA: All of the plants that are growing right now are exhibiting flowering. If they haven't already started growing pea pods, they are flowering, which is awesome. There are a few reasons why, when growing seeds, germination and sprouting won’t occur. Most of them coming from human interference.

To make sure that your Soil Supreme is performing well, simply water regularly and make sure that you have sufficient drainage so that it doesn’t become too saturated in water. It’s never been easier to grow strong, healthy, and robust plants. A special blend of Sphagnum Peat, Fytocell Foam, and our unique Organic Growth Stimulant. Plant Magic – Soil Supreme makes for a superior growing medium that always yields the best results. EMMANUEL MENDOZA: Howdy. My name is Emmanuel Mendoza. I'm a junior aerospace engineering major, minoring in mathematics and agricultural systems management at Texas A&M University. For the organic grower they have the oldtimer granules to boost the beneficial microbe population. They also have their dual action natural pest and fungus control spray - Bugicide.

STAY UP TO DATE WITH THE MAGIC…

CHANG: He's even seeing growth in 100% simulated Martian soil, though the plants are less healthy and have smaller leaves. SHAPIRO: Mendoza mixed simulated Martian soil and frass in different ratios to see what best supported growing English pea plants. SHAPIRO: Now in college, he's running an experiment, trying to do what Matt Damon's character did - grow plants in Martian soil - well, simulated Martian soil. Plant magic (or Plant Magic Plus, to give them their full name) are a dyed-in-the-wool British nutrient manufacturer.
