why cover seeds of hardy plants
Last year I decided to see if hollyhock seed just about to fall from them would germinate and grow.
I just tossed them onto some spare ground and have had just about 100% germination . Some are nearly in flower.
Nature does not sow in seed trays and then prick out .Nature is trying to ensure only the strong do well.
Tomatoes that have self seeded are going to provide me with a bonus,they did not need a greenhouse for birth the seed knew when was the correct time to germinate.They are not far behind their cosseted neighbours raised so early in the year.
Also this is how new strains are developed naturally and why Darwins ideas seem to be so sound ...
