General Care and Maintenance
Watering

- Water at the base of the plants to minimize leaf wetness, helping to prevent fungal issues.
Fertilizing
- Utilize a balanced fertilizer at planting and again during active growth to support healthy leaf development. Adding compost before planting can improve soil nutrition and structure.
Pest and Disease Management
- Keep an eye out for common pests like aphids and flea beetles. Regular monitoring is vital for early detection and management.
- Employ organic pest control methods or integrated pest management strategies to safeguard your arugula from diseases and pests.
Harvesting
- Harvest arugula leaves when they reach a desirable size, typically around 4-6 inches. Frequent harvesting encourages new growth and prolongs the harvest period.

In my garden I try to compost as mutch as possible, so I can mix in the nutrient ritch compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you dont have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.
You can read more on Community Composting here: https://www.epa.gov/sustainable-management-food/community-composting
If you are uncertain of the quality of your soil, you can get easy to use soil tests at amazon for 17 dollars. Check latest prices here: Soil testing kit.
Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan you crops according to your climate you will succeed with any plant you want.
Using Mulch
Mulch protects the soil by regulating temperature and retaining moisture. Organic mulch like straw or compost insulates the soil and keeps roots warmer, which is especially important in spring and fall.
Mulch also helps retain moisture by reducing evaporation, which means less time watering and less stress on plants. It is especially helpful in raised beds and containers where soil dries out faster. Additionally, mulch controls weeds, stopping them from competing with your vegetables for nutrients.
The Sun Joe CJ603E Wood Chipper is an affordable and effective option for creating mulch from branches up to 1.7 inches thick. It’s available for $199. Check the latest price on Amazon.
