Growng Agave from Seed
When planting agave seed what is the preferred growing media?
Botanical Journeys Plant Guides
Agave plants need a soil that drains very quickly or they may rot. Mix your favorite commercial potting mix, half and half, with sand or crushed rock.
Plant the flat, black seeds while they are fresh for best germination. Cover the seeds with the soil mix and water the pot or tray gently to avoid dislodging them.
Set the tray in a warm spot. Fresh agave seeds should sprout within a week.
Agave seedlings begin life with a single leaf. By the time the 3rd or 4th leaf has appeared, the first will be turning yellow and shriveling.
This is normal.
Keep the seedlings in good light--enough to maintain good leaf color. If the foliage takes on a purplish tinge, the seedlings are in too much sun. If it turns yellowish, they need more light.
Water them regularly but sparingly and they should develop into healthy plants.Growing Blue Agave Plants
