Seed Collecting

Come Autumn, after you have completed all divisions in the garden, if you’re still looking for a
project to keep you out of doors for THAT much longer, start collecting seeds that you can
sow in the spring.

What you’ll need:

  1. small scissors to nip off the seeds heads
  2. paper bags or envelopes to put the seed heads in as soon as they're cut. They give you
    room to give the seeds a good shake to release ones stuck to the heads. You need to
    label the envelopes immediately, or trust me you WILL forget what they were.
  3. a marking pen - first and most importantly, always harvest seeds when the weather
    is dry. Mid day sun is best, but if that isn’t possible, lay the seeds out singly on newspaper
    in a dry place for a few days. Then you may put them into paper envelopes for storage.
    Naturally, in your enthusiasm some of the seeds you're so anxious to collect won't be ripe.
    Sometimes, they won't even be mature enough to ripen and you'll have to toss them out.
    But the majority will ripen properly if you put them somewhere dry. At this stage, they really
    need to have enough room for the air to circulate.
    The seeds are always where the flowers were, because the seeds grow at the bottom of the
    style (the bit that sticks up in the middle of the flower). Sometimes, the seed pod forms
    behind the flower (as in daffodil), but most of the time, the seed pod grows inside the flower
    at the bottom of the style.

When the seeds are ripe, nature will disperse them. If you want to collect them yourself, you
need to wait until just before they would be dispersed naturally, because you know that they will
be ripe then. The seed pod will become dry and will usually change colour, probably from green
to brown or white, and the seeds inside will change from green or white to brown or black. Think
of the apple - the seeds inside an unripe apple are white. When the apple is ripe, it changes
colour and the seeds inside become brown.

Not all seeds collected will grow true to form. This is because some plants are cultivars, which
means they were produced through clonal reproduction. So if you plant seeds in spring that you
gathered in fall, the ensuing plant may look very different than what you had in mind.

After collecting and labeling your seeds, it is best to store them in a  cool, dry, dark place.

A freezer is NOT the best place for seed storage as certain seeds need different dormancy

Your best bet is to research each seed collected individually to get the best results, and it
just so happens you have all fall and winter to do so.

Good Luck and Happy Researching!
