<aside> 💡 People always ask me where they can buy the things I mention in this book and my videos, I now have a solution for you, I’ve listed these items in my Amazon Store. The store includes comments on most items, please read these! Sometimes I refer you to a cheaper place to buy than Amazon for example.

I rarely sow anything directly into the open ground. I seems easier at first, but over the course of the plants lifecycle it's actually much easier to sow in modules. Like everything in life there are exceptions, the most notable of which are carrots and parsnips, but lets set those aside for a minute and see how I normally sow seeds.

Seed Starting Compost

Over the years I've tried a dozen different seed starting composts and I've almost always regretted it. I now stick with a single supplier who I trust completely.

In my worst experience I started my whole winter sowing in September in a highly recommended compost, seeds grew but then stopped growing. I went on holiday for a week and when I returned I was puzzled to see no further growth. I waited another week and still nothing. I kept questioning myself until I finally confronted reality, these seeds were never going to grow. By now it was nearly October and I was way behind. I pricked out the seeds into different compost and spent two days desperately driving around garden centres trying to find something to plant for winter.

The pricked out seedling burst into life, I managed to find a few grotty garden centre rejects and we managed to grow just enough for winter, but it was very close.

The only compost I recommend even though it's not organic

The only compost I recommend even though it's not organic

Now I buy Levington Advance F2 Seed & Modular compost, it's completely consistent, suitable for everything, a joy to work with, but fairly expensive. However the cost is trivial by comparison with the value of the harvest, so it's unquestionably worth it, provided you are not 100% organic.

That said I’ve now changed my approach a little, to reduce costs and increase convenience. I still germinate in F2 but I fill modules 2/3 full with my local garden centre multi-purpose, which is less than 1/5 of the cost. The benefit is that I have one compost for almost everything and I use a small fraction of the F2 that I did before and my results are the same, maybe even better, because the multi-purpose has feed for 6 weeks, slightly longer than F2.

I made a video showing this approach:

<aside> 💡 I’m not specifically recommending Erin multi-purpose, but it works for me, my point in this video is that a cheap multi-purpose like Erin Excel seems to provide just as good results, provided the seeds actually germinate in the Levingtons F2. I’ve tried actually germinating the seeds directly in the Erin multi-purpose and the results were variable. However some viewers say that by just sieving the Erin compost, you can germinate in the finer resulting compost, this might be true. For me though, it’s just easier and more predictable to buy one bag of F2 a year.

Potting compost

As seedlings grow they need more nutrients and can tolerate more variance in the compost you use. Many things don’t need to be potted on though as they can be planted within 3-4 weeks, this applies to lettuce, spinach, chard, radish, turnips and lots more. Brassica’s often don’t need to potting on after being pricked out and can stay in seed compost for 6 weeks as can tomatoes.

There are three approaches to consider:

  1. Continue to use seed compost, this will usually be enough for 30 days in small modules (40 cell trays) and 60 days in larger ones (6 cell trays for example)
  2. Use seed compost, but give seedlings a liquid feed, this might be the right approach for tomatoes and peppers for example
  3. Use a higher nutrient multi-purpose compost, that will feed larger plants without the need for a liquid feed. A multi-purpose compost might be the best option, or a specific potting on compost.
