So, I came up with my own seed raising mixture. You can usually make your own, as long as it holds moisture and is not very rich in nutrients. Here is my very basic recipe.
You need a garden sieve, a couple of 10 litre (2 gallon) buckets, and a big tub to mix it all up in.
I used the following ingredients.
- 2 buckets of sieved compost (which once sieved equated to about 1 bucket in the tub)
- 1 bucket of fine coconut coir
- quarter of a bucket of sheep manure, crushed finely (in sack with lump of wood) and sieved
- 5 big double handfuls of worm castings.
All ingredients mixed well with gloved hands for about a good 5 minutes for even distribution. Then I wet it down with only a little water mixed with seaweed solution so that it was moist but not damp. If I squeezed it, no water would come out. I did a pH test with a tool I bought long ago and forgot I had, and it was about 7 which is neutral, so there was no need to add anything else to balance it.
Last year I used horse manure and a lot of grass sprouted, which confused me for a while as to what was the deliberately planted seed and what was the weed! This year I did not have the same problem with the Sheep manure. Not many weed seeds at all and only a few extra tomato seedlings sprouting from the compost!
Using this recipe, I had quite a bit of germination success. I also found that when planting tiny seeds all I needed to do was put the seeds on the surface and then use a kitchen sieve to just cover the seeds with mixture. Germination was a lot better than poking the seeds into the mixture with my fingers as I had done in previous years.
So, happy Spring planting to all in the Northern Hemisphere, and if it is not too cold, happy Autumn planting in the Southern Hemisphere. Happy planting where ever you may be. I just love the feeling of dirt between my fingers, what ever season it may be!
