Grafting cacti is a great way to add some color to your houseplants or home garden. While cacti are relatively low-maintenance plants, there are a few steps you can take to help your plant to thrive: Provide partial sunlight. Most grafted cacti do best in indirect light. Try an east or west-facing windowsill to provide just enough sun for your plants, without burning them with direct sunlight. Avoid overwatering. Cacti are desert plants and do not require as much water as many other plants. You should only water your grafted cactus once the soil is dry. You can also mist the tops of your grafted cactus occasionally to keep the scions colorful. Keep in mind that different times of the year may require different amounts of water—more in the summer, less in the winter. Measure the pH of the soil. Depending on your rootstock, you can find out the proper soil pH for your plant. Many cacti prefer an acidic-to-neutral soil that is properly aerated. Try a cactus fertilizer. Introducing the right cactus fertilizer during the growing season can help encourage healthy growth in your grafted plant.
