outdoor spider plants getting too big
I have several outdoor spiders that are getting too big, how do I trim them back? I live near Pittsburgh, so the winter will be severe.
Spider plants are tropicals and can't live through a northern winter, so you'll have to bring them indoors. You can cut the outer leaves back to leave a smaller plant. In fact you should do this as part of the acclimating process: https://www.gardeningknowhow.com/houseplants/hpgen/acclimate-plants-indoors-winter.htm
If you want to make some smaller plants, you can also cut the entire root ball into 2 or 3 pieces and repot them as new plants. https://www.gardeningknowhow.com/houseplants/hpgen/learn-more-about-repotting-houseplants.htm
