For some time, we'd been toying with the idea of growing soft fruit bushes from seeds – there's plenty of space on the greenhouse shelves for starting them off. Growing fruit from seed is a fraction of the price of buying rootstocks, even if they're bare-rooted. The major downside is that it may take much longer to get the plants established from seed.
It was actually more difficult to find seeds than established plants, although I had managed to find one eBay supplier based in
However, we ordered some raspberry and cranberry seeds for around £1 per packet, and they arrived at the beginning of June.
Looking at the instructions provided for each type of fruit seed, they were both very similar. To cool the seeds for at least a month, and preferably longer, presumably to fool them into thinking it's darkest winter from which they will then awaken and burst into life when the temperature is returned to normal. This process is called 'stratification' by the horticulturists.
