There is, however, one group of seeds you should not cover at all: very small seeds, those that are almost as fine as dust. Their small size indicates that, in nature as in the garden and in containers, they prefer to germinate on the surface of the soil.
'revealed seeds') are a group of woody, perennial seed-producing plants, typically lacking the protective outer covering which surrounds the seeds in flowering plants, that include conifers, cycads, Ginkgo, and gnetophytes, forming the clade Gymnospermae The term gymnosperm comes from the composite word in Greek: ...
After you plant your seeds cover the container with a plastic cover or plastic wrap while the seeds germinate. This keeps the moisture in to aid in the process. Once you see signs of life remove the covering...even if it's just 1 or 2 seedlings.
I have two go-to cover crops that I grow and recommend. Buckwheat, a warm-season tender annual crop and crimson clover, a cool-season hardy annual crop. Both are easy to grow and can be incorporated into the soil with a shovel or with equipment.
Covering the seeds with a delicate layer of soil creates the perfect microclimate for sprouting—a balance of suffused light and ample oxygen availability.
Seeds are very sensitive to the extremes of overwatering and underwatering. In addition, heavy-handed watering can disturb newly germinated seedlings. Securing plastic wrap over the surface of a freshly sown seed pot can help to keep the moisture level constant.
Pre-Soaking.
This method could be the fastest way to germinate seeds. Place seeds in a shallow container in warm water and leave them for 16 to 24 hours (smaller for 16, bigger for 24).

Mustard and rapeseed are used as cover crops and have been shown to suppress some soil borne pests. When the mustard plant that is still green is incorporated into the soil and decomposition starts, glucosinolates are released. The breakdown products of these glucosinolates are thought to have biofumigant properties.
Cover crops should be planted soon, so they get as much sun as possible as we head into winter. For the beginner, a cover crop seed mix is easiest – it should contain both legumes and cereals (like oats, barley or rye).
You won't have to water after they are planted, preventing seed movement. Create a mini greenhouse by covering the seed tray with a plastic tray or plastic wrap. This will keep the moisture and warmth inside, and you shouldn't have to water again till after the seeds have germinated.
Covering your precious newly planted grass seed with polythene sheeting is not only effective protection from birds but also drying winds and torrential downpours. It is very cheap, easy to lay, and speeds germination. Covering freshly sown grass seed with polythene sheeting to protect it from birds is a great idea.
Wildflower seeds don't need to be planted in holes; however, they should be tapped down to encourage growth. After you've scattered them over the soil, use the back of a shovel, your hand, or your foot to gently press them into the ground.
Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit). There are more than 1,000 species of gymnosperms still found on Earth.
Scatter sowing works really well for some species, but it isn't suited for all flowers, herbs, and vegetables. It's a good method for plants that grow best when directly sown but it isn't appropriate for plants that need more care during the germination stage and need to be started in seed trays.
Mustard seed germination is fast and sure, so you can simply scatter the seeds over a renovated bed and then pat them in with your hand or the back of a rake. Within two weeks the planted area will be transformed into a sea of green, with very few weeds.
Peas and vetch fix nitrogen, while the oats produce organic matter. It will greatly enrich soil if turned under as a green manure. For feeding, oats are the fiber and digestible energy, while peas and vetch are the protein.
Overwatering can be a silent killer for mustard plants. Look for yellowing leaves, mushy stems, and root rot as telltale signs. On the flip side, underwatering manifests as wilting leaves, dry soil, and crispy leaf edges. Both extremes can stress your plants and hinder their growth.
Gymnosperm seeds are typically formed in unisexual cones and are known as “naked” seeds since they lack the protective cover angiosperms provide their seeds.
After sowing the seeds, mist the tray with water and cover it with plastic wrap, a plastic bag, glass, or plexiglass to seal in moisture. As soon as the seed germinates, remove the covering. Ventilation and air circulation are also important to discourage damping off diseases.
Soaking your seeds in water is another simple trick to germination. Soaking in water can either help soften the seed coat to wake up the hiding embryo or can leach out chemicals in the seed coat that are preventing germination until conditions are right.
Both methods are effective, but soil germination offers a smoother transition to outdoor planting. The paper towel method is ideal for testing seed viability and saving space.
Seed germination is a complex process involving a series of physiological changes mediated by environmental cues. From the moment of dispersal, seeds rely on water availability, temperature, and, in some cases, light, to initiate germination or simply break dormancy (Bewley et al., 2013).
