And, of course, harvesting ripe seeds means you can grow some more if you want to
Or, otherwise. :lol:
This is my first Heavenly Blue Morning Glory Grow.
Any experienced growers that can help me out?
When is the optimal time to harvest the seeds for highest alkaloid content?
I've heard Sunrise or Sundown.
Also, should the seeds be fully ripe, or could I harvest them if they're still a bit unripe?
I'm storing them in an amber glass bottle with a Silica Gel packet to absorb moisture.
Thanks in advance
Morning glory can be re-established into larger area once mature and strong enough to do so. I started this plant in small pot, continued with moving to medium pot, than planting it outside near the bottom of a fairly tall climbing vessel, so to speak, allowing it to stretch out and remain wrapped around the vessel. Bamboo sticks are great to use for baby plants to grow with. Babies should be kept indoors, imo. Once they are medium sized they can be outside in a safe location. Wind, rain and any mild storms will encourage growth.
The idea is to move this method to the medium pot, so it continues to grow up. There should be enough vines as this is easier for the plant to rest itself on the final climbing vessel. In time, the plant will grow onto it. Morning glory has a history of being named 'snake plant' due to its ability to wrap itself around anything surrounding it. Also, temp should be above 15-20 degrees, although you want to water less.. 2-3 times a week, or less if it rains and keep it in full-part sun. Especially full sun in the morning. Beautiful and rewarding flowers in the morning.

They tend to fall off later in the day where the seed will form much later. More flowers, moar harvest!
This plant will be and is soon going into harvest around early-mid-late Sept, onto mid Oct EST. Check your own area season for ipomoea tricolor/violacea. Here, this will be the time ipomoea flowers reduce blooming than pods begin forming, let them dry up. You'll want to gently open the outside pod and out come fresh brown, black-white seeds. Some soft and bendable while others may be slightly harder.
Their taste isn't as earthy as store bought dry weight, ime. They should have distinct characteristics similar to dry-weight and some may be too fungus!

Be careful in knowing that fungus penetrates the seeds production and many other micro-organisms can disrupt that and can lead to contamination or deadly growths. Avoid any discolored seeds, or anything other than brown, black or white, those are safe! The seeds I harvested last year were slightly more watery, appeared visually as dry seeds but some had this white glow to them, and also less glycosides. Far easier to chew up or possibly extract. Far potent, too, so plan right. :thumb_up:
