Growing Mexican Sunflower from flower seeds is very easy and rewarding. Directly sow the flower seeds into prepared seed beds after all danger of frost has passed. Amend the soil with organic compost a couple of weeks before sowing the Tithonia seeds. Sow the seeds in groups of 2 - 3 seeds spaced 12 - 18 inches apart. Thin the seedlings to the strongest plant.
Tithonia can be grown in pots, but some say it's not recommended because they can grow large and quickly. If you do want to try growing tithonia in a pot, you can consider using a dwarf variety, like "Fiesta del Sol". Here are some tips for growing tithonia in pots:
Use a container with large drainage holes and enough room for the plant to mature. A 5-gallon pot is usually enough for one plant. Use loose potting medium and water until the soil is moist. Sow a few seeds in the pot and lightly cover them. Light is needed for germination, so don't bury the seeds too deeply.
Put the pot in a spot with filtered sun. Tithonia prefers warm climates and temperatures between 70°F and 85°F. Water daily and make sure the soil is well-drained. You can also pinch back the plant to encourage bushier growth. Tithonia can be heavy, so you might want to stake it to keep it upright.
