Depending on the weather, the optimal time to sow seeds is between the last five weeks of summer and early autumn. At this time, daytime and nighttime temperatures are decreasing, there is more dew on lawns, and annual broadleaf weeds and crabgrass are dying.
This indicates that new turf can establish itself with little to no competition. This is without a doubt the best time of year to sow seeds. If you miss this opportunity, you will have to wait an entire year for the next opening. When sowing seeds, be vigilant. Kentucky bluegrass mix can take up to six weeks to fully emerge, whereas perennial rye can emerge in just one to two weeks.
If you sow during drought conditions and the seed does not germinate, resow immediately. Establishing something before the ground freezes is crucial and will have a significant impact on what you can do with the new turf the following spring. The following year’s crabgrass control will be enhanced by the fall density of your turf.
When is the optimal time to seed a lawn?
Fall is the optimal time to sow new grass seed into an established lawn of cool-season grasses. However, depending on the type of grass you have, spring overseeding can also be effective if done early enough to allow seedlings to mature before the onset of summer heat.
When should seeds be planted in the spring?
Spring Grass Seeding Could Cover Vacant Areas – Return to Lawn Agent Articles Typically, spring is not the ideal time to overseed a cool-season bluegrass or fescue lawn due to the shorter establishment period and increased weed problems. Spring could be a viable option, however, if executed correctly and maintained with care.
- Best time to seed grass in the spring The optimal time to sow seeds in the spring is between mid-March and early April.
- Similar to fall planting, the soil must be prepared before planting.
- The suggested method is vertical slicing.
- A verticut is a soil-slicing tool that creates the necessary seed-to-soil contact for germination.
Typically, simply scattering the seed on the ground results in a poor stand and a waste of time and resources. A garden rake can be used to scuff up very small areas. After preparing the soil, seed can be broadcast. The fun of overseeding then begins, as the soil must be kept moist during germination and early establishment.
- This necessitates light, frequent water applications based on weather conditions.
- The good news is that spring temperatures are cooler and more cloudy, and rainy days are likely to reduce the watering needs that are typically observed during September’s hot days.
- Timing of grass germination for spring sowing Depending on the temperatures, the length of time required for grass seed to germinate will vary.
Expect emergence to take at least two to three weeks, if not longer. Once the seed has germinated, reduce watering frequency to as needed. This means watering the seedling grass when it exhibits signs of stress, such as wilting or a bluish cast. Spring-seeded grass has a shallow root system.
My recommendation is to not attempt spring seeding unless you are committed to summer watering. Without regular summer applications, the spring grass is likely to die during the dog days of summer, leaving you back at square one and out of pocket. Additionally, spring-seeded grass will need a bit more fertilizer to sprout and grow.
At the time of sowing, apply a starter fertilizer. Four weeks after germination, apply a second application of fertilizer with a high nitrogen content, such as 30-0-0, and, if possible, find a formulation with a percentage of slow release nutrients. This helps to spread out the feeding and reduces summer stress by limiting the nitrogen application.
- Spring grass seed germination problems Crabgrass germination has historically been one of the problems associated with spring sowing.
- This pesky weed thrives in areas with insufficient turf coverage and disturbed soil.
- Thankfully, newer crabgrass control products can assist us in overcoming this issue.
The active ingredient Dithiopyr is recommended for spring seeding because it can be applied later in the season and still provide effective control. This product is effective both as a pre-emergent and on crabgrass seedlings that have already germinated.
In the majority of seasons, it can be applied between the beginning and middle of May and still provide excellent season-long control. In fact, some product labels indicate that it can be applied as early as two weeks after germination, or when the new grass is two inches tall. January and February is the time to decide whether to sow spring seeds or wait until the fall and hope for a summer miracle.
Planning will lead to success regardless of your choice, as will knowing the proper steps.
