How to Identify and Treat 5 Common Arugula Diseases
There are some plants that make you acutely aware of the presence of diseases in the world. They seem to attract any and every pathogen wandering around out there.
If roses popped into your mind while reading that sentence, we are on the same wavelength. I love them, but a season without a single disease is a miracle!
On the other end of the spectrum, there are some plants that might make you forget that disease is even a thing.
For example: arugula. That beloved peppery green in the cole crop family seems to be ignored by fungi, bacteria, and oomycetes.
We link to vendors to help you find relevant products. If you buy from one of our links, we may earn a commission.
But in reality? It’s not, though. Pathogens can attack arugula, and when they do, things can go from good to bad really quickly.
One day, everything’s coming up, er… roses? And the next, the leaves of your greens are collapsing in a yellow or brown heap.
Take heart. On the bright side, if you catch problems early on, most are pretty easy to address, and you can still see a happy, healthy harvest.
Here’s the list of diseases that we’re going to go over:
Now that you know the suspects to watch for, you need to understand the symptoms of these ailments and what to do about them.

Sowing a seed directly into the ground, nurturing it, and reaping the rewards is one of the easiest gardening activities you can do—yet many gardeners don’t. There are many reasons to direct sow. Often, you’ll have earlier harvests because the seeds will germinate when it’s the perfect time to grow, and stronger seedlings because transplant shock isn’t an issue. Planting seeds in general (instead of buying transplants) gives you more varietal options, and you can also save a lot of money (1 packet of 30 to 150 seeds often costs less than a 6-pack of plants). And then there is the personal satisfaction factor. Ask any child who has planted a sunflower seed how they feel when that flower towers over their head, and you’ll understand what I mean.

Common juniper (Juniperus communis) is one of only three conifers native to the UK. It’s a member of the cypress family and grows on chalk or limestone in lowland areas, and moors, woodland and cliffs in northern Britain. Juniper is in decline in wild populations and has been designated a UK Biodiversity Action Plan priority species. This special tree has disappeared from several areas in the south of England. Many remaining colonies are so small that they’re considered functionally extinct. Scotland is now the stronghold for 80 per cent of the UK’s juniper trees.
