Curled up on your couch, sharing a blanket with Fluffy, and nursing a sweet warm tankard of cocoa, you look up from your book to notice that something has gone notably awry. Your jade plant has sprouted new jewels and your spider plant is crawling all over the floor. They are serenading you with the songs of spring, no matter how wildly you gesture towards the thermometer and shiver. The days are longer and your house plants are looking to stretch their legs. Spring cannot come soon enough.
If your babies have gotten much larger than they were last season, it may be time to re-pot. Just remember, don’t upgrade the container’s size too much. Allowing too much soil beyond the root ball will allow moisture to stand in the soil, possibly causing root-rot. Never increase pot diameter more than an inch or two, to ensure your roots will effectively pull the moisture from the soil.
Make sure your re-potted plant has good drainage, which means a deep pot with drain holes in the bottom. Do not put rocks in the bottom of your pot because that will just bring the wettest part of your soil right up to the tenderest of your roots which will cause root-rot.
With a new slightly wider, deeper home with good drainage, your growing house plants will do great this spring.
