POTTING PLANTS

Asked March 27, 2016, 8:29 AM EDT

MOST PEOPLE PLANT THEIR SEEDS IN SMALL CONTAINERS AND TRANS PLANT THEM TWICE INTO BIGGER CONTAINERS BEFORE PUTTING THEM IN THE GARDEN. IS THAT NECESSARY OR CAN I PLANT THEM IN BIGGER CONTAINERS RIGHT AWAY? ALSO, CAN I USE A FLUORECENT LIGHT OR DO NEED A SPECIAL BULB FOR ARTIFICIAL SUN LITE FOR MY SEEDLINGS? THANKS FOR ALL YOUR HELP.

Thank you for the question. This quote from the University of Minnesota's publication on starting seeds indoors explains it like this: "It's best to use divided containers with a single seedling per container, rather than filling a larger container with potting mix and sowing many seeds, because the seedlings' roots will grow into each other and are likely to be injured later during transplanting". Here is the link to the entire article: http://www.extension.umn.edu/garden/yard-garden/flowers/starting-seeds-indoors/
Standard "cool white" fluorescent bulbs provide enough light for seedlings. The lights should be 2-3 inches away from the plants and should be turned on 12 -16 hours per day. It helps to have the light on some sort of chain so as the plants grow, the light can be raised. You shouldn't need to buy expensive light bulbs.
Thank you for contacting Extension.
