Seasol works immediately as a fast-acting liquid, providing a tonic to plants and improving soil health right away, with visible improvements in plant health often seen within days to a couple of weeks, especially for stress relief or revitalisation. For best results, especially with lawn care, consistent applications every 2-4 weeks during the growing season are recommended to maintain strong roots, better colour, and overall plant resilience.
Seasol is a fast-acting liquid that goes to work immediately whether applied to the soil or foliage. Regular applications, every 2 to 4 weeks, will give the best results. Being completely natural, it's safe on all plants including Aussie natives. Seasol is available as a concentrate or hose-pack.
Do you water your lawn after applying Seasol or PowerFeed lawn products? Seasol Lawn & Turf Starter, Seasol for Lush Green Lawns and Seasol for Buffalo Lawns are all liquids, which are readily absorbed into the lawn and the soil. Therefore you do not need to water them in.
Seasol for Lush Green Lawns is a fast-acting liquid that can be applied every 2 to 4 weeks during spring, summer and autumn. It's got all the good gear for health and stimulation of lawns and soil for above and below the ground. Remember, with all these products you don't have to apply them at once.
Seasol® Lawn Care is the perfect combination of seaweed and trace elements to revitalise your lawn and soil. It helps promote healthy growth, enhances foliage colour and protects your lawn from heat and drought stress.
Our two application recommendations for normal use are stated on the product and involve either monthly applications from March to October or three seasonal applications in Spring, Summer and Autumn.
No, October is generally not too late to fertilize; in fact, it's often an ideal time for the final fall application to promote deep root growth before winter, as long as the ground isn't frozen and the grass has significantly slowed its top growth. This late feeding sends nutrients to the roots for winter survival, ensuring a healthier lawn in spring, but it should focus on potassium and phosphorus rather than quick-release nitrogen to avoid stimulating new blade growth.
Liquid Seaweed is a fast acting solution that will start showing results within 7-10 days. Any light green patches will start to turn a darker lush green. It's particularly useful when drought is expected as it will act as a wetting agent to help prevent the lawn going brown.
Symptoms and Signs of Over-Fertilization
Feed the grass.
Lucky you, but you still need a spring lawn fertilizer to help your lawn grow lush and green. Use Scotts® Turf Builder® Lawn Food around the time of the first mowing. This helps Northern lawns have enough nourishment to plant roots for strong growth.
To get dark green grass, apply a fertilizer high in nitrogen and iron, water deeply but infrequently, and ensure proper mowing, but the fastest method involves a liquid iron supplement for quick results, which boosts chlorophyll production, while good soil health (correct pH, aeration) supports long-term deep color.
Seasol is especially effective when used directly onto foliage as it's absorbed through the leaves. Seasol promotes healthy roots, encourages beneficial soil micro-organisms, stimulates flowering and fruiting and helps plants to cope with stresses like heat, drought, frost and pest and disease attack.
When it comes to lawn fertilizer, timing is crucial. In addition to looking at the weather forecast, you should consider whether your lawn is wet or dry. Ideally, you should apply a fertilizer treatment to a dry lawn when there is no rain forecasted for the next couple of days.
This plant tonic, encourages plants to grow new roots and as autumn approaches you will be amazed how quickly your sick plants come back to life. You can't overdose on Seasol. It's not a Fertiliser.
October isn't too late to spray for many weeds, especially perennial and winter annuals like clover and dandelion, as they actively store energy for winter, making fall applications highly effective for root control; however, effectiveness decreases with colder soil and frost, so aim for mild, dry days when weeds are still green and growing, but stop before deep freezes.
In fact, gentle showers following the treatment can even aid in better nutrient absorption, especially when using water-soluble granulated formulas. Heavy Rain Immediately After Fertilization: Heavy rain, on the other hand, can wash away the fertilizer, preventing your grass from benefiting from the nutrients.
Always follow the product label instructions precisely for application rates. Overfeeding is never a good idea. Consistency is key!
Over-fertilization can cause leaf burn, stunted growth, and even plant death. 2. Will over fertilized plants recover? Yes, over fertilized plants can recover with proper care.
The General Rule of Thumb. In New England and other northern climates, it's best to stop fertilizing perennials by early September. This gives plants time to slow down naturally and prepare for dormancy. Further south, where the frost arrives later, you can usually extend that window into late September.
Plants that don't like seaweed fertilizer are typically those needing lean soils, like Mediterranean herbs (lavender, rosemary), cacti, succulents, and certain native plants (like Proteaceae if high in phosphorus), as seaweed adds nutrients and can be too rich, but its micronutrients and growth hormones are generally beneficial for most others. Use it cautiously on high-nitrogen lovers or tender seedlings, and rinse if using fresh seaweed to remove salt.
Yes, you can sprinkle fertilizer on top of the soil (called "top dressing"), but you must water it in well, or wait for rain, to help it dissolve and move nutrients to the roots, preventing fertilizer burn by keeping it off the plant and distributing it evenly around the plant's base. For some granular types, lightly scratching them into the top inch or two of soil can be even better, but always follow product directions and avoid clumps.
How Long Does it Take Fertilizer to Work? Most fertilizers start showing results within one to five days after it's been fully absorbed by your lawn. Slow-release formulas often take a bit longer, but you'll still likely see a difference in your lawn's health within a couple of weeks.
The best time to apply fall fertilizer is typically from late September through early November, once daytime temperatures cool but before the ground freezes. A slow-release granular fertilizer works best, especially one with a balanced nitrogen content.
Always follow the manufacturers recommended rates and application methods. Fertilize outdoor plants in the coolest part of the day, such as early morning or late evening, especially in hot summer weather. Always water in fertilizers well to distribute nutrients throughout the soil profile and to prevent burning.
The best fall fertilizers are high in potassium, provide steady nitrogen without pushing top growth, and often include soil-health boosters like humic acid or carbon. Top recommendations: Stress 12-0-24 — high potassium + micronutrients for stress resistance.
