Christmas cacti are some of the most popular plants, with striking festive shapes and brightly-colored flowers. Some specimens have grown to a height and width of three feet! If you want a Christmas cactus for your home, here’s how to grow one from scratch.

  • First, you’ll need a pot at least 12 inches wide and 18 inches deep. You can use any pot or container holding water. A terra-cotta pot, an old flowerpot, or even a Rubbermaid container will work fine.
  • Next, you’ll need to fill the pot with fresh soil, either purchased from a garden center or made from equal parts sand, loam (a type of clay), and organic matter like compost. Christmas cacti prefer well-drained soil, so water it just enough.
  • If you’re growing your Christmas cactus from seed, start by germinating the seeds in damp soil overnight. Once they’ve germinated, remove the young plants from their pots and place them in a sunny spot where they will grow rapidly.
  • Once the plants have reached the juvenile stage, water them regularly and fertilize them with a weak solution of phosphorus and potassium. Once they reach the adult stage, prune them back to their original size, removing any dead branches and roots, and water them once a week.

When it comes to Christmas cactus, size does matter! While some varieties can grow up to a foot tall, others only reach a few inches in height. So if you’re looking to make your cactus look especially festive, here are a few ways to help make it bigger:

  • Plant multiple Christmas cacti together. If you want your cactus to be even bigger, try planting two or more together. As long as they have similar growing conditions, they should all grow well together and create an impressive display.
  • Use a propagator or hydroponic system. If you can get your hands on one, using a propagator or hydroponic system can help increase the size of your Christmas cactus significantly- even allowing it to grow up to eighteen inches tall! Just be sure not to overwater or let it get too dry- both of which can stunt its growth.
  • Fertilize regularly. A well-nourished Christmas cactus will be much healthier and look better than one that doesn’t get enough nutrients. Feed it a good fertilizer every two weeks or so, and watch as its size increases significantly!
  • Grow succulents inside. Succulents are a great option for adding more height to your Christmas cactus. They’re hardy plants that require very little care, making them a great choice for those who don’t have much time or green thumb to spare. Just be sure to give them plenty of light and water, and you’ll be able to enjoy an impressively large cactus in no time at all!
  • Use a Christmas cactus as a planter. If you don’t have any room for a full-grown Christmas cactus, consider using it as a planter! Take the stem off the plant, fill it with soil, and replant it in the ground where you want it to grow. Your guests will love the festive addition to their landscape!
  • Make your own artificial Christmas tree using holiday lights. This is probably the easiest way to make your cactus look especially festive- all you need is some holiday lights and common household items like wire cutters and scissors! Cut off the bottom of your lights, remove the wires, attach them back together in whatever way you like, and then hang them from your Christmas cactus!

Care Requirements For A Christmas Cactus

Christmas cacti are often grown as houseplants, but they do well in various settings, including outdoors in warm climates. They require cool temperatures and plenty of light, making them perfect for homes near the windows. However, like all plants, Christmas cacti have specific care requirements that must be followed to ensure their long-term success. Here are the most:

Keep Christmas cactus in an area with medium to bright light. They do well with at least six hours of direct sunlight daily but prefer brighter surroundings.

Fertilize Christmas cactus monthly with a balanced fertilizer diluted to half strength. Feed them less during the winter months when there is little sunlight available.

Water Christmas cactus regularly; keep the soil moist but not wet. Allow the potting mix to dry out between waterings, then re-water until the soil is damp before letting it dry out completely. Do not overwater!

Prune holiday cacti annually in late winter or early spring using sharp scissors or a knife to remove any dead or damaged branches; leave one or two healthy branches at each node.

If a Christmas cactus shows signs of stress, such as yellow leaves or wilted flowers, it may be time to move it to a new pot or give it a fresh start.

Christmas cacti are considered semi-hardy plants, meaning they can tolerate some frost but do best in warm climates. If you live in an area that experiences cold winters, consider planting a Christmas cactus outside in a sunny spot.

When the holidays are over, remove your holiday cactus from its pot and let it dry out for one to two weeks before placing it back in its original container.
