![Page 12: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/12.jpg)
What’s required?
• All growing medium must achieve certain functions.– Growing Medium: Material in which the roots of
plants grow
![Page 13: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/13.jpg)
Growing Medium Must:
• Provide nutrients• Provide a place for plants to root, and anchor
themselves• Aeration (presence of oxygen) – Provided by pore spaces: air holes between
particles
• Hold moisture
![Page 14: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/14.jpg)
Which Medium ?
• Below are photographs of possible mediums. Explain why each would work, or not work, as a growing medium for plants. 3 sentences per photograph please! You will only add water to your plant.
![Page 15: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/15.jpg)
Nutrients
• Plants need nutrients to grow! – Sometimes found in growing medium– Plants grown in soilless medium need help! =
Nutrient supplements!
• Be careful nutrients do not leach !– Leaching: Nutrients run out of the medium,
causing the grower to continually add the nutrients.
![Page 16: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/16.jpg)
Important!
• Soil must be able to drain excess water!
• Plant roots need oxygen to function ! – Extra water would cause plants to suffocate and
possibly rot
![Page 17: Concept Map!. Warm Up Define medium Properties of Growing Media Introduction](https://reader035.vdocument.in/reader035/viewer/2022070116/56649e585503460f94b5206c/html5/thumbnails/17.jpg)
