The Q&A Archives: Non-growing Catnip

Question: After planting four packs of catnip, not one sprouted from any of the four packets. Why?

Answer: The seeds of Nepeta cataria (catnip) should sprout in 7-21 days at 60F to 70F degrees. These seeds should be sown on the top of moistened seed starting mix and pressed in with your hand, rather than buried in the medium. After sowing, cover the tray or pot with plastic wrap and keep it in a warm place like on top of the refrigerator until most of the seeds sprout. Then remove the plastic and place the seedlings in a brightly lit area. After the sprouts have developed two sets of leaves, apply a diluted solution of liquid fertilizer. When they've developed 4 sets of leaves the plants should be put into individual pots. Try again, following the above guidelines, and you should have lots of little catnip plants.
