Hello How long do W. Robusta Seeds stay fresh I have like 20 left and also I sowed two more W. Robusta seeds like two weeks ago and i checked on them and they have mold on them. They still good or should i dicard? could it be the soil? or too wet? I got windmill palm tree seeds too, do i have to prep them with Hydrogen Peroxide and water like it tells me to w/ warm water for 24 hours? And how long to germinate? it says like 8 to 12 weeks is that true? And are they fast growers like the W. Robusta?
