Persistently wet surfaces, limited machinery access and heavy rootzones are continuing to remind us that March is still very much late winter.
Although temperatures are not especially cold, Atlantic weather systems are forecast to keep conditions unsettled for a while yet. For golf courses, sports pitches and amenity turf areas, that means the balancing act of maintaining playable surfaces continues.
Even when the weather still feels cold and miserable to us, turf is already responding to increasing day length and gradually rising soil temperatures. These changes influence plant hormones and metabolic activity while reactivating microbial processes in the rootzone.
Growth often arrives suddenly in short weather windows. When those moments appear, surfaces with healthy rootzones and active soil biology tend to respond far more quickly.
Extended wet weather can leave turf systems with several challenges beneath the surface. Prolonged soil saturation reduces oxygen levels in the rootzone and slows microbial activity. Over time this weakens soil structure and restricts root development.
Common symptoms heading into spring include:
Even when surfaces begin to dry, the soil biology beneath will take time to rebalance. That’s why early spring management is often less about pushing rapid growth, and more about helping the soil system recover from winter conditions.
As soil temperatures begin to rise, biological activity in the soil also starts to increase. Microorganisms break down organic matter and release nutrients that turfgrass can use for new root and shoot growth, helping plants establish stronger root systems early in the season.
Applying high levels of nutrition too early in the season can stimulate shoot growth before the root system and soil biology are fully active, resulting in weak or poorly supported turf development.
A few principles are particularly important during this transition period:
Protect soil structure
Avoid unnecessary traffic on saturated surfaces wherever possible, particularly on heavier soils where compaction damage can persist well into the season.
Encourage biological activity
Supporting soil biology as temperatures rise helps improve nutrient cycling and root development. Natural extracts such as seaweed or wood-derived biostimulants are often used for this purpose.
Focus on root development
Strong root systems early in the season provide the foundation for resilient turf through periods of wear, stress and summer heat.
Plan nutrient inputs carefully
Avoid simply applying nitrogen or NPK blends by default. Soil or tissue testing can help identify what the plant actually requires. Amide-based liquid feeds can also be useful early in the season, as they tend to be lower in salt than conventional fertilisers, less prone to leaching and gentler on soil microbes as biological activity begins to recover.
For now, many golf courses and sports surfaces remain firmly in late-winter mode. But spring rarely arrives gradually. Surfaces with healthy, biologically active soils tend to respond far more quickly when growth conditions improve.
Supporting soil microbial activity as temperatures rise can help accelerate the transition from winter dormancy into active growth. Natural biostimulants such as kelp-based products like MarineVera, or wood-vinegar extracts such as PyroVantage, are increasingly used to encourage early root activity and stimulate microbial processes within the soil.
After such a persistently wet winter, preparing rootzones now may prove one of the most important steps in setting turf up for the season ahead.
Spring growth arrives quickly once conditions change. Supporting soil biology, protecting soil structure and focusing on root health during this transition period can help turf respond more effectively when growth resumes.
