Question

Collect different types of seeds and put in a small bags. Lable them​

Answer 1

Answer:

You must wait until the seeds are ripe. Good indications that the seed is ready is when they change colour,  usually getting darker or when the pods begin to split in readiness to shed their seeds. Bear in mind that on most plants, not all the seed heads ripen at once, so collecting seed can continue for many weeks, so if you missed the first lot you’re bound to get another chance later on.   

Seed heads should be as dry as possible when you collect them. Pick a dry day when there isn’t too much wind as many seeds are very light and easily blown away.
