Just got some huge 3 stem poinsettas. Need to repot them, but my container is quite a bit bigger than the little pot they shipped in. Will that negatively affect them? Would not be root bound at all. Also I was going to plant them in Moisture Control potting soil? Now afraid that will keep it's roots too moist/wet, what do you think? Thanks

If you repot your poinsettias while they are in bloom, the stress may affect the leaves and they won't be as attractive as they might otherwise be. On the other hand, if you prepare the container by filling it with moistened potting soil (moisture control potting soil is just fine), then make holes in the soil with the pots the poinsettias are currently in, you can slip the poinsettias out of their pots and pop them into the new container, press them down carefully and then water them in well to help settle the soil. If you repot without disturbing the roots, the plants may not even know they've been replanted. It's true that root bound poinsettias will develop more flower bracks and have brighter foliage, but being root bound is not absolutely necessary - think of the plants that spend all year in the ground in Mexico (where poinsettias originate). As for the moisture retaining potting soil, it should be fine for most plants. The particles that retain the moisture pellet-like and they release moisture as the surrounding potting soil begins to dry out. Your plants won't be sitting in soggy soil so the roots should not be affected to any great degree. You can control the amount of moisture your poinsettias get, and water only when needed if you water by container weight rather than appearance of the top of the soil. Simply water thoroughly and then pick up the container so you'll know how heavy it is when the soil is saturated. Then periodically pick up the container. When it begins to feel light rather than heavy, it's time to water again. Be sure to watch your plant, too. If the leaves begin to wilt, it's time to water! Good luck with your poinsettias!
