I work strictly from hands-on experience in synthetic turf and landscape installation rather than seed-start gardening or horticulture. While I understand the basics of germination, I don't have the kind of day-to-day, plant-specific seed-starting experience your article is looking for, and it wouldn't be appropriate to present that as expert insight. For this piece, you'll get stronger, more publishable quotes from: Market gardeners or nursery growers who start seeds at scale Master Gardeners or horticulturists Vegetable or flower growers with propagation experience They'll be best positioned to speak confidently about light-dependent germination, seed size differences, surface sowing, and specific seed examples. If you're working on a future article related to landscape installation, site preparation, drainage, or artificial turf decisions, I'd be glad to contribute.
Seeds that need to be covered are typically larger, energy rich seeds. These types of seeds rely on darkness and steady to germinate. Vegetables like peas, beans, corn and squash should be sown beneath the soil to keep them from drying out. Flowers like nasturtiums and sweet peas need to be sown underground too due to their larger size. Covering seeds protects them from drying out, temperature fluctuations, and disturbance from watering or wildlife, giving them a much more reliable start.
