Seaweed contains a range of excellent nutrients to replenish deficiencies and generally strengthen your roses, allowing them to thrive.
Liquid Seaweed when applied as a foliar spray to roses does wonders. I've used it for years and always with great results. The foliage turns a darker green, the colors on the blooms becomes more intense and the canes seem hardier. And overall the plants seem happier.
A regular, generous application of well rotted animal manure or compost and blood and bone are perfect for roses. Avoid manure from animals that eat meat and use chicken manure sparingly - as these are too acidic for roses.
Boosts soil health, improves soil moisture and nutrient retention. Increases worm and microbial activity. Safe on roses and all flowering plants.
Seaweed fertilizer is most effective on tomatoes, potatoes (Solanum tuberosum), cucumbers (Cucumis sativus) and strawberries (Fragaria x. ananassa, hardy in zones 4-8). Seaweed extract can be applied in several ways, including as a foliar feed or a soil application.
You can apply a seaweed solution in early morning or late afternoon. It can be applied over the foliage and around the root system of the plant. It is usually applied every 2-4 weeks. You can continue to water your plants anytime after applying the product.
Seasol is the perfect partner for any garden project. It is a natural seaweed plant tonic that gives ALL plants including natives a real boost and helps to improve overall plant health and growth. Seasol helps to stimulate strong root development and enhance flowering and fruiting.
A high-quality organic fish fertiliser (such as Charlie Carp) in either a liquid or pellet form is perfect to provide these nutrients to the plant. Charlie Carp is a perfect fit for roses as it can also be mixed with other green products such as Eco-Oil and Eco-Fungicide, providing defence against pests and diseases.
Do not apply Seasol and PowerFeed during the heat of the day. As PowerFeed is a fertiliser it may burn the foliage of the plant or lawn. If fungal problems are an issue, it is best to apply Seasol and PowerFeed in the morning to avoid moisture residue on the foliage overnight.
The Sin: Overfertilizing. The common misconception is that more fertilizer=more blooms, but roses only need so much fertilizer, and adding too much synthetic fertilizer can kill natural soil bacteria and/or lead to salt burn, which can both harm your plant.
They are a fast-acting source for magnesium and sulfur. For soils on the alkaline side, the added sulfur is a benefit. Epsom salts, however, do not contain any of the three major components of most fertilizers—nitrogen, phosphorus or potassium—and therefore would not be a complete fertilizer for roses.
Rose leaves turn yellow because the pH of the soil is too high, or there's not enough iron in the soil. It can also be caused by a lack of oxygen when the plants are overwatered or the soil doesn't drain easily. You may see the leaf veins turn yellow while the leaves are still green.
Start feeding older plants in spring when new growth is about 6 inches long. Most will benefit from a second feeding of liquid fertilizer after the first bloom, and repeat-blooming roses do best with regular feeding every 2-3 weeks until late summer.
Seaweed has long been used to help plant growth, especially before the advent of commercial fertilizer production. It provides many benefits to plants above and beyond conventional fertilizers to promote stronger, healthier plants.
Seaweed has been used as a soil improver for centuries, particularly in coastal areas. Seaweed contains several useful plant nutrients, including nitrogen, potassium, phosphate and magnesium.
Dilute 1 ml of solution with 1 litre of water.
Fill it in a spray bottle. Before spraying seaweed solution on leaves, clean the leaves first. There should not be any traces of dust, otherwise there is no point in giving fertilizer.
Seasol and PowerFeed are liquids, they are readily absorbed into the soil and the plant foliage. Therefore you do not need to water them in.
You can't overdose on Seasol. It's not a Fertiliser. But it does have amazing healing qualities. One capful in a 10 litre watering can will treat around 4m2.
For optimum results it should be applied to the garden every 2 weeks, more frequently (every week) if plants are under stress. Unlike fertilizers, Seasol can be applied all year round, even in winter and at the height of summer.
You can certainly apply the Dynamic Lifter Pellets to your roses. This product can be used on all garden plants and it can be applied every 6 - 8 weeks during the growing season.
Fish, blood and bone meal fertiliser is another common variety of bone meal fertiliser and is made from fishbone and blood rather than beef bones. It can be used across a wide variety of plants and is ideal for fruit, vegetables, flowers, roses, shrubs and trees.
After completing pruning during winter it is best to spray roses with Lime Sulphur. This helps to eliminate fungal spores and eggs from pests, giving you a fresh start come spring. This is especially important for rose gardens that have trouble with black spot and mildew during the growing season.
Drawbacks of Seaweed Fertilizer
Due to the limited macronutrients in seaweed fertilizers, you may need to supplement using things like liquid fish fertilizer or fish meal. There are also commercially available fortified liquid seaweed products with pre-added nitrogen, phosphorus, and potassium.
Yes, Seasol and PowerFeed (liquid) is taken up very effectively through foliage as well as through the soil.
Of all the fertilisers, seaweed has the broadest and most balanced range of nutrients, to promote early flowering and cropping and increases the sugar content of fruit. All in all, it's very good stuff.
