I started plugs and seeds soaking on 2-16-2018 and so far I’ve planted a total of 216 seeds consisting of Jackie, Metallica, Jack’s Purple, Bonnie Fox, Salmon Jack, and others. All seeds planted so far are grown hoping for new cultivars.
Plumeria Seeds, something to soak the seeds in, 2” x 3” Gro-Tech FlexiPlugs and trays, Vitazyme, Carl Pool’s Root Activator, Pro-Mix BX Mycorrhizae, Metal Labels or plastic plant markers and permanent felt tip marker.
Each year I try to verify the products and methods by experimenting with variations on last years proven methods. This year I’m comparing the use of FlexiPlugs and Pro-Mix as starter methods. I also use a control tray from what I determined to be the best method from last year.
- I put 72 seeds in plug trays filled with Pro-Mix and the rest in trays filled with FlexiPlugs.
- The reason I’m trying the Pro-Mix is to see if the Mycorrhizae makes a difference on newly planted seeds and young seedling.
- I pre-soaked older 2016 seeds for two hours – four hours. The seeds that didn’t plump up and felt paper think, I discarded.
- The reason is to test the viability of the seeds and enhance germination time.
- I pre-soaked the plugs for about 1 hour or longer until the plugs are completely saturated. I use a mix of 1 oz Vitazyme, 2 oz Root Activator per gallon of water.
- The reason I use Vitazyme is that it is a biostimulant that fosters plant growth and development throughout the seedlings life cycle from seed germination to plant maturity in a number of ways.
- The reason I use Root Activator is that it is a 100% natural product which safely promotes regeneration of roots through increased elongation rates. Root Activator stimulates fast root growth, reduces transplant shock, and hastens plant establishment. Also, the root activators are designed to attach to the soil and not wash out as easily as root stimulators.
- The remaining seeds were placed directly in the plugs.
- The reason I place them in the plugs without soaking is they all appear to be viable and by pre-soaking the plugs I have provided plenty of moisture to germinate the seeds.
- After planting the seeds, each tray was soaked overnight in a mix of 1 oz Vitazyme, 2 oz Root Activator and 10 drops of Merlin’s Magic Potion per gallon of water. Allowing the plugs and seeds to be saturated with the mix.
- Then I placed the trays in a location that gets about 7 hours of full sun. Day time times here are now in the mid to upper 80s and nighttime temps are in the low 70s.
- The reason I place in full sun right away is mainly for the heat. All a seed needs to germinate is moisture and warmth. The full sun and air flow lessen the chance of damping off. Damping off typically occurs when a seed is planted in cool, wet soil and is further increased by poor soil drainage and poor air flow.
I water three to four time a day, keeping the seedling mix and plugs very moist. I have to be careful and watch the Pro-Mix, I expect it to hold more moisture than the plugs.
Note: Cotyledon or the seed leaf is involved in the storage of food reserves. In plumeria, the seed leaf exists in pairs and show above the ground and perform photosynthesis, a function similar to a true leaf. A new seedling can and will take up nutrients even while seeds leaves are still present. I soak the soil and plugs to be sure nutrients are available as soon as needed.
