How To Plant Wild Rose Seeds

Recently someone asked us about planting wild rose seeds. Julie our Greenhouse Manager answered her with these comments; Sarah,
It does take up to 2 years or longer for the Wild rose seed to germinate if you plant it directly into the ground. Mother Nature will take care of the treatment processes throughout the seasons to instigate germination. If you choose to grow these plants in a greenhouse setting they will require some extra effort for you to be successful. The seed needs to be scarified, lightly scoring the seed coat to allow moisture into the seed. Then there must be a cold moist stratification period of 60-90 days followed by a warm period of about 80 degrees for 60-90 days which in turn should be followed by another cold treatment of 60-90 days before seeding. This is an involved process but a successful outcome is very satisfying.
Good luck to you.

How to Propagate Plants

Propagation is any process used to multiply the number of plants in a group. There are basically two methods for doing this. Sexual propagation involves increasing plant numbers by germinating seed & growing the seedlings to maturity. This is probably the most widely used method by the majority of growers, including many agricultural grain crops. There are many different ways to pre-treat seed for attempting germination in the artificial setting of a greenhouse. These are processes used in an effort to overcome seed dormancy & attain successful germination on a man made schedule. Mother Nature does a wonderful job of overcoming dormancy so seed will germinate at the safest time for the seedlings to emerge into a growth friendly environment. We try to imitate those processes to successfully grow plants indoors.

Asexual propagation encompasses a variety of processes including leaf, stem, & root cuttings. Those slips that your Mom put into a jar of water in the kitchen window & watched until roots formed so she could plant them into the garden are simply stem cuttings. We would probably not agree that the water bath is really the best medium because of the high risk of mold developing but it sure seemed to work well for Mom! Dividing clumps of plants, such as Hostas, when they get very large is another form of asexual propagation. Planting bits of a rhizome root will give rise to new plant growth & is another form of cutting. The practice of grafting which is often used with roses & fruit trees is a type of asexual propagation.  Another example is the layering used with raspberry canes where they are bent over to the ground & covered with soil where new roots will develop. All of these asexual methods develop plants that are essentially clones of the original specimens.

Q&A On Establishing a No/Mow Low/Grow Lawn

No Mow Low Grow Grass

Mowing

How often can they mow it for a manicured lawn look and does this have any detrimental effects on the lawn?   Usually within 6 weeks.  How often can they mow it for optimum lawn performance?  Is once per month adequate?  Once per month should be adequate if mower is adjusted to 4” height.  It can, however, be mowed just like a normal lawn if desired.  If you prefer not to mow, the lawn will take on a beautiful low, soft meadow appearance.

Sowing rate and procedure
What is the recommended seeding rate and the best installation procedure?  Our site contractor said it will most likely be machine broadcast with straw mulch placed on top.   They have stripped the topsoil, stockpiled it and will be respreading it in all lawn seeded areas.

Seeding the Low/Grow No/Mow Lawn

Seedbed Preparation: Till the soil approximately 6 inches deep. Level with garden or landscaping rake. Surface may be firmed by rolling or soaking, then re-raking till level. Leave top ½ inch loose to allow seed to be worked into soil.

Fertilization: Prior to or right after seeding, apply a starter fertilizer to help proper root development. Continue using a systematic fertilizer program to maintain a healthy lawn.

Seeding: Sow seeds evenly at 7-10 lbs/1,000 square feet. Rake lightly into soil. No more than 1/8 inch of soil should cover seed. Roll with a water roller.

Covering: Use blankets, pelletized or paper mulch, or straw to hold soil moisture and hasten germination. Baled straw may bring in unwanted weeds; use with caution.

Watering: Do not allow soil to dry out. Keep soil moist with frequent light watering until seedlings are visible. After lawn is established, water as necessary.

Mowing: Maintain mower height between 2 to 3 inches, never remove more than 1/3 of the grass plant with each mowing.

Weed Control: It is very common to see new weeds when planting a new lawn or disturbing the soil. For new lawns, wait 6-8 weeks before using any herbicide. For existing lawns, the best weed control is to maintain a healthy lawn by regular fertilization, proper mowing, and watering as necessary.  If Aurora Gold Seed is used, Roundup herbicide may be applied the second year at the recommended rate for Aurora Gold as it is tolerant to Roundup if used with right application amount.

Recommended time to seed
We are anticipating a May seeding time.  If we run into June for seeding is that o.k.?
Cool season grasses such as the Low/Grow No/Mow germinate best when the soil temperatures are between 50° and 65° degrees F. These soil temperatures usually occur when the daytime air temperatures are between 60° and 75° degrees. Fall is the best time to plant  cool season grasses. Planting in the Fall presents the least risk of planting failure for cool season grass. Plant your cool season grass seed when the fall temperatures reach 75° and are dropping as winter approaches. Alternately the second choice is to plant in spring when spring temperatures have reached 60 and are rising in the spring. Planting in summer can occur, but irrigation becomes a critical factor in establishment. High temperatures of summer can cause the grass to go dormant so planting during summer is not recommended. Planting when night-time temperatures are above 70° should be avoided.

Provide us with any specifications for installation.
Three Planting Issues
should be observed when creating good seed / soil contact and thus insuring proper germination of your seeds:

The primary one is that seeds mu
st be planted (covered by soil) at the correct depth.  With most grass seeds that depth is 1/8 to 1/4 of soil above the seed.  With other types of seeds, planting depth can be deeper, but with grass seeds, this depth is often a critical factor in obtaining good germination.

Second is that good seed/soil contact also means that the soil has good moisture and that the soil is in CLOSE contact with the seeds allowing moisture in the soil to enter the seeds.  Often slightly firming the soil after planting with a light roller presses the soil tighter around the seeds thus improving the germination of seeds.

Third and a key factor in getting seeds to germinate is that the temperatures (and season) must be right for the particular type of seeds (see when to plant) planted AND there must be adequate soil moisture for the seeds to germinate.  Depending on the soil type, watering may be required for multiple times daily in order to keep the top inch or two of soil moist (not wet) for the seeds and seedlings (germinated seed plant) to grow.
