Martin Baldwin’s Moss Rose Moss rose forms a mat of needle-like foliage and cup-shaped flowers in vibrant shades of yellow, orange, pink, and white, making it an ideal groundcover for hot, dry areas. Sow seeds directly in the garden after the last frost date, or start them six to eight weeks in advance indoors.
What is the optimal method for germinating flower seeds?
How to Germinate Vegetable and Flower Seeds in Paper Towels Julie Martens Forney Some seeds have naturally tough seed coats that make it difficult for water to penetrate and facilitate germination. The magic of a garden is brought to life by seeds, which produce beautiful flowers and delectable fruits and vegetables.
- The transformation of a seed into a plant begins with germination, when a seed sprouts a root, followed by a stem and leaves.
- Many gardeners germinate their seeds on paper towels before transplanting them into soil.
- Why is it important to germinate seeds before planting? It allows you to examine the viability of your seeds.
It allows you to sprout many seeds in a sandwich bag, a very small space. In some cases, it can accelerate the process of seed germination, with roots appearing in a matter of days. It is applicable to both flowers and vegetables and fruits. To germinate seeds, saturate a paper towel or coffee filter with water.
- Select a towel that is durable when wet.
- This variety retains moisture longer and does not produce lint on seeds (lint can give mold a place to grow).
- Because seedling roots cannot penetrate filter paper, coffee filters are effective for transferring germinated seeds to soil.
- Place the seeds within the wet towel or coffee filter, and then slide it into a sandwich bag.
Because a tight seal can promote the growth of mold, the bag should not be tightly sealed. Place the baggie in a warm (65-75°F) location, such as a laundry room, a southern window, or a sunroom. Check the towel for moisture and the seeds for mold growth.
- If the towel becomes dry, mist it.
- The seeds should germinate in a few to seven days.
- Once growth appears, transfer the seed to moist soil.
- Place small seeds directly on the soil surface without covering; bury larger seeds to the depth specified on the seed packet.
- If the root grows into the towel, cut the towel around the root at planting time and bury it with the root.
Robin J. Carlson, representing the Chicago Botanic Garden To speed up the process, germinate seeds on a paper towel. The seeds of yellow squash germinate easily on a moist paper towel. Some seeds have a tough seed coat that is almost impermeable to water, making germination challenging.
Sweet pea, shell bean, nasturtium, and morning glory are some examples (above, from lower left, clockwise). Soaking seeds like these in water overnight is often beneficial. Numerous gardeners also include hydrogen peroxide, which softens the tough seed coat and sterilizes the solution. Utilize a mixture of half water and half peroxide.
On seed packets it is commonly recommended to “nick” the seed coat. This increases germination success by creating a physical opening in the seed coat through which water can enter. Use the blade of a nail clipper to make a small incision in the seed coat.
- Place the cut on the opposite side of the hilum, which is a depression on a seed that indicates where it was attached to the seed pod.
- Eeping the cut away from the hilum protects the delicate seed leaves contained within the seed.
- Julie Martens Forney Use a file to nick the tough seed coats of moonflower seeds, which are large enough to be held comfortably while filing.
Using a file to create an opening in a seed coat is an alternative method. Rub the seed against the sharp edge of the file until a small opening is created. After nicking the seed coat, seeds must be soaked overnight for several days, until they swell and the seed coat cracks.
Julie Martens Forney A root tip can be seen at the top of the seed. Combining nicking with a water-hydrogen peroxide soak until the small root tip appears is one way to hasten germination of seeds with a tough seed coat. This method accelerates germination, allowing you to start your garden sooner. Unfortunately, there appears to be a problem playing this video.

Generally, you should sow smaller seeds at a shallower depth. Some of the smallest can be scattered on the surface of the soil. If you sow small seeds too deeply, they will not germinate; therefore, you should always check seed packets for recommended sowing depths.
What month should flower seeds be started indoors?
General Guidelines For When To Plant Seeds Indoors – Unfortunately, not all companies include planting dates on seed packets (perhaps they prefer to keep us guessing). Therefore, if yours does not include the recommended planting dates, here are some general guidelines you can use to determine it.
In general, you should start seeds indoors six to eight weeks before your region’s average last frost date. For instance, the average date of the last frost in growing zone 4b (Minneapolis, Minnesota) is May 15. So, I would count backwards 6 to 8 weeks (which would be March 20th to April 3rd) and plant my seeds indoors at that time.
The average date of the last frost varies by growing zone. If you do not know the name of your plant, consult a local garden center or search online. Related: 17 Easiest Indoor Seeds to Start My seeds are started indoors early
What seeds should I start indoors during the month of March?
In March, what Vegetables Should You Plant? Consider it premature to begin working on your spring garden? March is the ideal time to plant cool-weather vegetables that can withstand early spring’s cool temperatures. It is also an excellent time to sow a variety of seeds indoors so they will be prepared for early planting.
Once you’ve prepared their beds, you can sow seeds for many cool-season vegetables in March, including broad (or fava) beans, which are among the hardiest vegetables available. Carrot, beetroot, kale, leeks, broccoli, horseradish, chicory, and turnip seeds can also be planted. In addition to spring onions, spinach (enrich the soil with organic matter), peas, shallots, and parsnips are also excellent early vegetables to plant in March.
In March, you can also sow herbs like dill, chives, and coriander directly into the ground or, if you prefer, in containers. In March, you can begin seeding a variety of vegetables indoors (or in a greenhouse), including brussels sprouts, cauliflower, spinach, perennial herbs (all under cover), chili and sweet peppers, and celery.
- If you have a greenhouse, you can also begin sowing tomato, cucumber, and gherkin seeds.
- In four to six weeks, or generally by early to mid-May, you will be able to plant any seeds that have been started indoors and under cover.
- Salad leaves, which can be grown in a pot or a greenhouse, are another excellent vegetable that can be sown in March.
As soon as your soil is ready, you can also plant asparagus and rhubarb crowns, shallot and garlic sets, and artichoke tubers. In our region, it is common to purchase pre-grown seedlings in packs of three, four, or six, allowing you to get an early start on certain types of cool-season vegetables.
Not all vegetables are typically available in this form, but Broccoli, Cabbage, Cauliflowers, Brussel Sprouts, Lettuce, and Onions are. Acquiring and beginning early with these pre-grown seedlings reduces your planting and preparation time while giving you an early start in the spring. Remember that early planting does not mean that these cool-season vegetables are “Freeze-Proof,” but rather “Frost-Proof,” meaning they will not survive the hard freezes that are still possible in February.
You may be surprised by the number of vegetables that can survive March’s cooler temperatures, but if you begin planting now, you’ll have fresh, homegrown produce in no time. It is worth your time, believe us! Which Vegetables Ought to Be Planted in March?
Do you germinate seeds in dark or light?
For Seeds to Germinate, the Proper Environment Is Required – For seeds to germinate, temperature, moisture, air, and light conditions must be optimal. All seeds have optimal germination temperature ranges (Table 1). Minimum temperature is the lowest temperature at which seeds can effectively germinate.
Maximum temperature at which seeds can germinate. Anything above or below this temperature can damage or induce dormancy in seeds. At ideal temperatures, germination is uniform and rapid. Moisture is necessary for all seeds to initiate the internal processes leading to germination. Typically, this represents 50-75 percent of the field capacity of field soil.
For optimal germination, a fine-textured seedbed and good seed-to-soil contact are required. Aeration of the soil medium facilitates the exchange of gases between the germination embryo and the soil. Just like any other living organism, seeds respire. They require oxygen and emit carbon dioxide (CO 2 ).
This carbon dioxide must have the ability to escape the seed. If the soil or medium is not adequately aerated as a result of overwatering or compaction, the CO2 will not dissipate and the seeds will suffocate. Not all seeds require the same amount of light. Most seeds germinate most effectively in darkness, and light may even inhibit germination (e.g., Phacelia and Allium spp.).
Nevertheless, some species (such as Begonia, Primula, and Coleus) require light to germinate (Miles and Brown 2007). Don’t confuse the light requirements of seeds with those of seedlings. All seedlings require exposure to sunlight. If seedlings do not receive enough light, they will become frail and stunted and will not produce to their full capacity.Table 1. Soil temperature conditions for vegetable crop germination.

The soil temperature should be measured by inserting a thermometer 3 to 4 inches below the soil’s surface and recording the reading. Based on work by Kemble and Musgrove (2006).
