I raise a lot of seeds and thought it might be helpful for beginners. These are some tips for those who struggle to raise 'plant babies'.
When growing edibles I always start with organic, heirloom and my own saved seeds so there's no chemical nasties. Fungicides are sprayed on many brands of seeds to prevent rodents and insects from tucking into them during storage. So choose what you buy carefully!
If your seed packet date says it has expired - don't throw the seeds away! If you've stored them well, a percentage are likely to still be viable. These are some ways you can use old seeds up.
If your budget doesn't extend to new trays or seed raisers, try repurposing everyday kitchen containers like plastic punnets that berries come in. The lids often have ready made holes - perfect mini greenhouses.
Another sustainable option to save money & avoid landfill is to reuse your toilet rolls, egg cartons and paper towel rolls as seed raisers. Kids love decorating them. I give them a pair of scissors once the seeds are sprouted, so they can enjoy a healthy snack while giving their baby plants their first 'haircut'. I've found if they grow it, they eat it!
A quick summary of some of the main tips I use to raise seeds successfully. I go into more detail with step by step instructions and pics on the blog post.
