Planting Calendar for Tithonia

It's not a good idea to plant tithonia until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant tithonia in Cameron is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant tithonia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your tithonia may not have a chance to grow to maturity. If you are starting your tithonia indoors then you might be able to get away with starting them a few weeks earlier.
