Celery is perfect for small gardens. While planting celery 6” (15cm) apart is recommended, squeezing that spacing to 4” has some benefits. It may lower your harvest per plant, but you’ll get more harvest overall since you have additional plants. This is a great option for people with small growing spaces.
For container gardens, choose a container that is 12” (30cm) wide and at least 12” (30cm) deep for four celery plants or cutting celery clusters. This will give you and your family of four several celery stalks for 2 out of 3 meals daily.
6. Water, Water and More Water!
Celery is 95% water by weight, and needs more water than most vegetables. It’s a marshland plant, so it prefers consistent moisture. That means watering each day (temperatures above 70) or every other day (temperatures below 70). Watering celery once a week typically doesn’t work unless you get significant condensation every night in your garden. How do you know if you need more water? If your celery plants wilt, water more.
Living in a hot, dry desert? Add 6” mulch to the soil which can drop the soil temperature by 10 degrees Fahrenheit! The soil holds more moisture which keeps roots cooler.
7. How to Harvest Celery for Maximum Yield
You might read that it takes celery 60-80 days before it’s ready for harvest. If you were growing a head of celery like you find at the grocery store, that might be true. But the good news is that you can harvest much sooner with this PRO tip!
PRO Tip for more abundant celery harvests: Cut what you need, when you need it. When the plant has at least 10 stalks, no matter how small they are, start harvesting and enjoying your celery. Simply harvest the outermost stalks and keep at least 7 stalks on the cluster at all times. Your plants may last the entire growing season with this continuous harvest method. That’s WAY better than waiting for one single head of celery!
To harvest, use a sharp knife or pair of scissors to remove each outermost stalk as close to the soil as possible. Keep the cuts as clean as possible as old plant material and ragged cuts are places for pests and diseases to fester.
8. Can You Store Celery For Later?
Like most herbs, it’s best to cut and use celery fresh. After all, that is the benefit of your garden, putting the absolute freshest food on your plate at each meal! But if you are harvesting a lot of celery at once, water is the trick to keeping celery fresh. One option is to place stalks in a glass of water on the counter. Display the vibrant green harvest while keeping it hydrated until you’re ready to use.
Celery is a staple in cuisines around the world! If you are considering preserving celery for all your winter soups, use a dehydrator to remove most of the moisture for long term storage. Pro tip: grind your dehydrated celery into a powder and store in an airtight container in a dark cool space to enjoy your harvests year round.
