4. For information about Norway maple control, click here. Avoid fluctuations in temperature such as a garage or storeroom that is cold in winter but blazing hot in summer. Norway maple trees are wonderful shade trees in the garden. That’s why weed control is so hard. Rinse seeds well with cool water (around 70ºF) and drain.
Keep seeds at a cool to cold temperature of 40 degrees or less. Soak Seeds. Many seeds can be sprouted this way but the germination might take longer depending on the genus. I only use seeds sold as human food for sprouting, since like the alfalfa seeds you mentioned, seeds prepared for use as seed/not intended for human consumption are often treated with fungicides etc. But if you prevent weed seeds from germinating, your garden will be weed-free. 1. 3. Avoid light and never store seeds in direct sunlight or a well-lit room. If stratification is required; sow seed at 0.25-1.00 inches in moist growing medium such as vermiculite, peat moss, or sand for a period of 60-90 days at 33-39 degrees Fahrenheit (place in refrigerator); upon development of first germinants, move all seed to warmer environment to increase germination rate. However, they produce many seeds and propagate so easily they readily escape cultivation. Remove any debris, stones, or broken seeds. You also may need to dampen the paper towel a few times a day or each day until the sprouting happens. I will be so excited if it keeps growing. Let the potting mix dry out completely between waterings. Keep the seed tray at room temperature while germinating and sprouting the maple tree seeds. Red maple seed matures in spring or early summer; collect immediately upon ripening. Set the seed tray in partial sunlight (about 50 percent) when the seeds begin to germinate. Unlike seeds and plants you buy from catalogs and nurseries, indigenous common weeds are naturally suited to the sun, soil, and water conditions of your garden.

Keep your seeds … Water the potting mix to keep the seeds evenly moistened, but allow the water to drain thoroughly. When sprouting smaller seeds, removing broken seeds is not practical, but do look for any non-seed material and remove at this point, if possible. 2. Place rinsed seeds in a jar and fill about ¾ full with cool water. Be patient. Keep the seeds in a 50/50 mixture of sand and peat moss in a perforated plastic Ziploc bag . Also, some seeds won't sprout as they need different conditions, such as seeds that need fire to germinate or to go through a bird gut first. The seeds of the silver and red maple don't need a period of stratification and can be planted immediately after harvesting.
