Is there anything else I need to know about Celery?
Keep the soil moist in dry weather.
Dark green celery can be quite bitter to taste. This is generally fine for cooking, but can be unpleasant to eat raw. Excluding light from the stems or "blanching" will produce paler stalks that are much sweeter in taste. When plants are close to harvesting, wrap the celery plant with thick newspaper, leaving the leaves sticking out at the top. The stalks will be pale and ready to harvest in around 2-3 weeks.
