I forgot to store the packets of seeds that I purchased last Spring such as pansies, petunias and cosmos in a sealed container or bag. They are still in date? I sowed them indoors nearly three weeks ago with very poor germination rates apart from the Cosmos. Cosmos is a bigger seed. I do think germination conditions were adequate. Is it worth testing these seeds using the paper towel method or are they dead?
I would be very grateful if you could help me identify the pest that is damaging to my Calendula plant. See photo below. Nearly all the leaves have this damage.
At what stage do I begin to feed seedlings - hardy and half-hardy annuals? i.e. Calendula and Petunia Is it when the first true leaves appear? How do I know that they are "true" leaves?
