Locals who have lived in the area for 40 plus years, tell me that these last 12 months have been the wettest.
With collecting flower seeds, I prefer to allow the flowers to dry completely on the plant, before removing the dead flowers to collect the seeds.
This of course is difficult when it rains all the time. So this year, I have been removing partly dead / dry flowers at a time when it isn’t raining. Then placing flowers of the same type together in a cane basket, to allow to completely dry within the basket. Keeping an eye that the flowers have good ventilation so they dry out and not get mouldy. Once completely dry the flower can be pulled apart to collect the seeds.
The above flowers are marigolds and zinnias, which will self seed (pop up next season by themselves from seed blown around but not manually planted by me). However I like to still collect lots of flower seeds, so I can manually plant them. This ensures flower plants grow where I want and need them.
