As winter sets in and the days grow shorter, the first widespread frosts of the season have made their appearance. But what happens if you’ve recently sown grass seed and it germinates only to be covered in frost? Does frost pose a threat to newly sown grass seed, and is there anything you can do to protect it? Let’s delve into the details.
Autumn is considered the optimal time for sowing grass seed. During this season, soil temperatures are generally high, and there is ample moisture available to facilitate successful seed germination. This stands in contrast to spring, where ideal seed-sowing conditions can quickly turn unfavourable if the weather becomes hot and dry. However, sowing grass seed in late autumn does carry the risk of encountering cold conditions. The positive news, though, is that newly sown grass seed demonstrates a considerable resilience to frost.
Your grass will be OK!
Young, recently germinated grass plants can withstand periods of air frost typically experienced in autumn. Interestingly, these young plants often maintain a slightly higher temperature than their mature counterparts. This difference is sometimes evident when areas of newly sown grass remain free of frost, contrasting with the ‘white over’ appearance of surrounding mature grass. While extended periods of deep ground frosts may negatively impact young seedlings, such conditions are unlikely in the autumn.
Nevertheless, the onset of frosts contributes to a decrease in soil temperature, slowing down the speed of germination and overall plant growth. This slowdown is a result of the inhibition of various biochemical reactions essential for growth in lower temperatures*. Additionally, cold temperatures can impact the availability of nutrients in the soil, as microbial activity responsible for breaking down organic matter and releasing nutrients slows down in colder conditions. This limitation can affect the essential nutrient supply for grass growth.
Keep off the grass!
Keep off the grass! Walking on frozen grass will damage the leaf and increase the chances of disease taking hold.
If your new grass happens to be hit by frost, it’s crucial to take one important step – stay off it! Ice crystals forming on the plant’s leaves can easily puncture the leaf when walked upon. The consequence is dark footprints that will turn yellow as the leaf dries out when the frost melts. While this damage is superficial and won’t kill the plant, it weakens it, making it more susceptible to diseases.
In summary, while frost may temporarily slow down the growth of newly sown grass and cause superficial damage, proper care and patience can help the plants recover. Avoiding walking on frosted grass and maintaining good lawn care practices will promote healthy growth once the weather conditions improve.
It’s not too late to sow.
Despite the onset of frosts, it’s not too late to sow grass seed! Perennial ryegrass will germinate in soil temperatures from 7 degrees Celsius, and red fescue from 11 degrees Celsius. Today, on the 16th of October, the soil temperature at midday registers at 10.2 degrees. Hence, although fescue may initiate growth slowly, it still falls well within the parameters for ryegrass-based mixtures such as Value Lawn Seed, Hardwearing Lawn Seed, and Multi-Purpose Lawn Seed.

Tall Fescue – The most drought tolerant grass
In an era where water scarcity is increasingly prevalent, we often get asked what is the most drought tolerant grass? Among the contenders, tall fescue (Festuca arundinacea) has emerged as a robust champion, showcasing its remarkable adaptability and suitability to drought conditions for lawns. This hardy grass species boasts an array of characteristics that make it an ideal choice for maintaining lush and verdant lawns even in times of water scarcity.
Deep Rooting System:
One of the key reasons tall fescue excels in drought conditions is its deep and extensive root system. Unlike shallow-rooted grass species, the roots of tall fescue can penetrate deep into the soil, reaching water sources that are beyond the reach of other grasses. This feature enables tall fescue to access moisture even during extended dry periods, making it more resilient and better equipped to withstand drought stress. The deep-rooted nature of tall fescue not only aids in water uptake but also enhances its overall stability, preventing soil erosion and promoting a healthier lawn ecosystem.
Drought Resistance Mechanisms:
Tall fescue has evolved various physiological and morphological adaptations that allow it to thrive in drought conditions. One of these mechanisms involves reduced water loss through its leaves. The grass possesses narrow leaves with a waxy coating that minimises water transpiration, conserving precious moisture during hot and arid periods. Additionally, tall fescue exhibits a capacity for rapid dormancy during drought stress, temporarily ceasing its growth to conserve energy and resources until more favourable conditions return*.
Heat Tolerance:
Drought often accompanies high temperatures, and tall fescue has demonstrated impressive heat tolerance, making it well-suited for regions prone to both dry spells and scorching summers. The grass species has the ability to maintain its colour and vitality even in the face of elevated temperatures, ensuring a visually appealing lawn throughout the year. Its heat resistance further bolsters its suitability for drought conditions, as it can endure the combined stressors of water shortage and intense heat.
Versatile Growth Habits:
Tall fescue exhibits a clumping growth habit, forming tufts or bunches of grass blades rather than a spreading carpet-like growth pattern. This growth habit is advantageous in drought-prone areas as it reduces competition for water and nutrients among neighbouring grass plants. As a result, tall fescue can better allocate available resources to its individual clumps, enhancing its ability to withstand drought stress and maintain its overall health and appearance.
Low Water Requirement:
One of the most appealing aspects of tall fescue is its relatively low water requirements compared to other common turfgrass species. While it is essential to provide sufficient water to establish the grass initially, once established, tall fescue can thrive with less frequent irrigation. This characteristic is particularly appealing for homeowners and landscapers seeking to conserve water without compromising the beauty and integrity of their lawns.
Adaptability to Various Soils:
Tall fescue exhibits a broad range of soil adaptability, another factor that contributes to its suitability for drought conditions. It can grow in a variety of soil types, including clay, sandy, and loamy soils. This adaptability allows homeowners and landscapers to choose tall fescue for their lawns regardless of the soil composition, making it a versatile and accessible choice for regions with diverse soil profiles.
In conclusion, tall fescue stands out as a resilient and drought-tolerant grass species that is exceptionally well-suited to lawns in regions prone to water scarcity. Its deep root system, drought resistance mechanisms, heat tolerance, versatile growth habits, low water requirements, and adaptability to various soils collectively make it an ideal choice for maintaining lush and verdant lawns even in the face of prolonged drought conditions. By selecting tall fescue for their lawns, individuals can not only enjoy a visually appealing landscape but also contribute to water conservation efforts and promote sustainability in their communities.
