No-dig gardener Charles Dowding says multi-sowing seeds is a great way to save time and space in your garden
Tell me, fellow gardener… if you buy a square of onion sprouts at the gardening supply shack, do you plant each little tiny bulb one by one, or do you bunch them? When you plant carrots, do you space your seeds apart, or do you just sprinkle and see what happens? Most gardeners I talk to thin them out, one by one, but master gardener Charles Dowding would disagree, so I wanted to talk about his multi-sowing seeds method, because this year I’m trying out both!
According to Charles Dowding, you can sow 4-5 seeds in the same place, and not thin them at all. The downside is that your vegetables might end up being smaller, but the benefit is that you can get more from a smaller space.
This year I’m trying the Charles Dowding multi-sowing seeds method with my onion seeds and onion sets (indoor seedlings). It’s not exactly scientific, but I have one row of onions spaced individually, and another clumped.
Who is Charles Dowding?
So if we’re going to go and follow some guy’s advice, you probably want to get to know him first, if you don’t already. Charles Dowding is a master gardener and gardening personality who has been vegetable gardening since 1981 and is most famous for his “no dig gardening” methods. He’s an author, writes for gardening publications, and has a YouTube channel.
No dig gardening in a nutshell, is the process of building up, instead of digging down. Your first year, you lay down cardboard or other material on the earth to block out any weeds, and then you add rich compost and manure on top. Each year, you build this soil with more compost and manure by a few inches, and you can use worms to aerate the soil. No additional fertilizer is needed, and the process is organic. Instead of feeding the plants, you end up focusing mostly on improving your soil every year.
The “no dig” portion of the method refers to digging into the flat earth, instead, you are creating a raised garden bed of soil with no box. It’s easy to maintain, and your garden will grow or at least compete with, any other type of garden for less work.
What About the Multi-Sowing Seeds Method?
Many people attribute the multi-sowing seeds approach to Charles Dowding, which is the practice of doing exactly how it sounds – sowing multiple seeds in the same place, which many gardeners do—but without thinning them out. These are the benefits that he sees with this approach:
- Get more plants growing in a smaller area
- Need less compost for more plants
- Save time on sowing and thinning
- A companion planting benefit, because plants of the same type like being planted together.
Dowding warns, ” Do not sow too many root vegetables in a clump, or you will have more leaf in proportion to root, meaning the roots will stay small.”
How Many Seeds Should You Sow in a Clump?
The number of seeds you sow, and how many can grow in a clump are different. Dowding suggests a few extra seeds per hole you plant, just in case not everything germinates. Here are some suggestions on multi-sowing seeds from the master-sower himself:
This isn’t an exhaustive list of everything you could multi-sow but it includes plants that work best for multi-sowing, according to Dowding. He says you can multi-sow seeds for just about anything, but you might not get a great crop.
For example, Dowding says you can multi-sow celery, you’ll just get thinner stalks which is fine if you’re just using celery for soups.
French beans are another exception, because they already grow and produce so much, there’s little point in multi-sowing. The point of multi-sowing seeds is to save time and space, not necessarily to yield larger crops.
So if you already have one plant that produces well on its own, there’s no need to multi-sow. Another exception is lettuce, which is difficult to harvest outer leaves when multi-sown. On the other hand, rocket salads are easily harvested and can be sown together.
Dowding offers online courses on his website for more in-depth tutorials on no-dig and multi-sowing worth checking out.
