How to Grow and Care
As the Baseball Plant often grows in partial shade in its native habitat, place it on a windowsill where it receives sun for only part of the day, preferably during the morning. If you move the plant outdoors during the summer, adapt it to the increased light gradually and position it under the high shade of a tree or shrub, where it will receive direct sunlight only at times of the day when the sun is not directly overhead. If it begins to lose its plaid coloring, it needs more light.
Like most succulents, the Baseball Plant will rot in soggy soil, so keep it in a clay pot filled with a potting mix intended for cacti. Use a pot with at least one drainage hole. If you don't have such a mix available, you can create your own by combining 1 part of regular potting soil with 1 part of coarse builders or horticultural sand and 1 part of horticultural pumice or poultry grit. From spring through autumn, water the plant thoroughly about once a week until water runs from the pot's drainage holes. At each watering, add a liquid 10-10-10 plant food at one-quarter strength, which should be about two drops of the plant food in 1 quart of water Learn more at How to Grow and Care for Euphorbia.
