Christmas cactus is a tropical plant that requires an organic soil mixture and lots of moisture. The plant likes bright light and average household temperatures. You can take it outdoors during the summer and fertilize it monthly with a diluted houseplant food. Then bring it back indoors at the end of September and provide total darkness for 16 hours each day so it can set flower buds. The easiest way to accomplish this is to place it in a bright room for 8 hours and then either put a box over it, or put it in a closet for 16 hours. It needs absolute darkness; even a short burst of daylight will retard the formation of flower buds. During this bud-forcing period, keep the temperature between 60 and 70 degrees, and do not fertilize the plant. In early December, your Christmas cactus can be brought into ordinary light and will bloom in a few weeks. It’s a lot to do at home, so we can see why many people buy new plants each year. I hate saying this, but that’s what I do — I’m not going through all this for a $4 plant.
What should I do to help keep my Christmas tree fresh?
The “nervous Nelly” in me is so uneasy about folks’ bringing a highly flammable object into the house, and especially when they’re keeping the house heated.
Do:
• Install only a very fresh tree or a living tree.
• Wait as late as you can to bring it into the house.
• Make sure it’s away from all heat source.
• If it’s a cut tree, have a good water source for the trunk.
• Check it daily — renew water often.
• Keep pets and children away from electrical cords.
• Keep a living tree’s root ball damp and cool. Some use ice cubes around the ball.
• Take it out as soon as it drops a needle or two.
• Use only LED tiny lights; never leave them on overnight.
• Always turn lights off when you leave the house.
Don’t:
• Let young children string lights unattended.
• Don’t use small (inexpensive) extension cords.
• Don’t string extension cords across the room (tripping risk).
• Never leave the room with candles burning.
• Never allow candles on the tree without adults there.
• Bypass the sentimental urge to use your family’s old lights or old decoration, as they may be flammable.
