All You Need to Know About Fertilising

Natalie Crofts

Spring heralds the arrival of a new growing season and with it the need to nurture your garden ready for a summer of glorious flowers and vibrant foliage.

Composting, mulching, fertilising, tidying… there is a long list of to-do jobs in the backyard at this time of year, but perhaps one of the most bewildering tasks is fertilising. Over time, plants absorb all the nutrients in the soil, so require some of that goodness to be replenished. That’s where fertilisers and tonics come in. Fertilisers feed whilst tonics repair.

We’ve put together a simplified guide to plant treatments to take the confusion out of fertilising this spring.

What is garden fertiliser?

In a nutshell, fertiliser optimises the growth, productivity and overall health of your plants by supplying the soil with the essential nutrients plants need to thrive.

You will see the letters N, P and K on all fertiliser products. This stands for nitrogen, phosphorus and potassium and these are the three primary nutrients required for healthy plant growth. Together these elements help to promote green, leafy growth (nitrogen), good root growth and plant development (phosphorus), and quality flower and fruit production (potassium). The ratio in which they appear will give you an idea as to what the product is designed to do. For example, lawn fertiliser will be much higher in nitrogen than potassium, to help encourage green, lush growth.

The NPK ratio is a key part of the label as it gives you a simple breakdown of nutrients. This is important as many native plants, for example, cannot tolerate high levels of phosphorus, so you need to find a fertiliser with little to no phosphorus. Or, for fruiting and flowering plants, it’s more important to have higher levels of phosphorus and potassium and a low level of nitrogen.

NPK is not all that’s in a fertiliser formula; there are other minor and trace elements used in smaller quantities, such as calcium, sulphur and iron, which all play an integral role in plant growth.

Your plants don’t need to be fed as often as we do, and over-feeding can actually cause damage, so getting the timing and levels right is important. But it can be a confusing and slightly daunting task to undertake as the type of fertiliser and frequency of application will depend on the species of plant you are growing, whether they’re native or not, the soil type and so on.

Generally speaking:

• Potted plants need to be fertilised throughout the year, as often as every eight weeks, as the potting mix the plants sit within contains little nutrients and, given the confined space, nutrients will deplete more quickly than in a garden bed.

• If you’re growing edibles in the backyard, regular fertilising will prove beneficial, particularly in summer when your veggie patch will appreciate a feed every 1-2 weeks.

• Flowering plants will need a regular application for a more prolific blooming cycle, whilst native plants may not need fertilising at all depending on the soil quality.

• One application of fertiliser at the beginning of the growing season works well for lawns, trees, shrubs and climbing plants.

Quick takeaway

What is fertiliser? Fertiliser contains essential nutrients formulated to enrich soil and optimise the growth, productivity and overall health of a plant.
When should I apply it?

Application frequency depends on the type of plant. Potted plants, edibles and flowers need fertilising as often as every 2-8 weeks, whilst lawns, trees, shrubs and climbing plants will be happy with fertiliser once or twice a year.

 

What is seaweed tonic?

A plant tonic is a powerful pick-me-up for weary plants or young seedlings that need strengthening. A tonic works quite differently to fertiliser as it is formulated to help your plants fight pests and disease, grow stronger roots, improve seed germination rates, promote early flowering and enhance the overall health of a plant.

If your plant is sick, experiencing transplant shock or is stressed from over/under watering, plant tonic is the perfect cure. It will also give freshly sown seeds or newly emerged seedlings a boost to help them grow up strong and healthy.

Hoselink’s Plant Tonic features seaweed, an all-round superfood for your garden. Seaweed has 60 trace minerals and nutrients including nitrogen, potassium and phosphate that will set your soil humming with life in no time. Among its health-boosting properties, seaweed stimulates the microbial fungi in the soil, increases soil structure, aeration and moisture retention, and assists in defending plants from soil-borne diseases.

When should I apply it?

Application of seaweed tonic can be a little more ad hoc and more frequent than a general garden fertiliser.

Seaweed tonic can be applied both to the soil and directly to the leaves of a plant for absorption when correctly diluted. It’s important to note fertilisers and tonics should not be applied in direct sunlight and in temperatures over 38 degrees. Seaweed tonic can be used 1-2 times per month during active growing periods, or as your plants require. Seaweed Tonic can also be applied during the winter months.

What is Lawn Fertiliser?

what-is-lawn-fertiliser

Lawn Fertiliser is a liquid concentrate that acts as a remedy and wellbeing liquid for your lawn. It includes all necessary nutrients your lawns love, such as nitrogen, magnesium, iron and potassium - think of it like a multivitamin for your grass!

To help with water retention, potassium fulvic acid has been added to the formula, this also assists by allowing the formula to reach all critical areas of the lawn and help the roots with absorption.

With regular application, the lawn fertiliser will help your lawn to have consistent lush growth year-round as well as reduced stress in wild weather conditions. The fertiliser also helps the lawn's root system develop and condition the soil for the healthiest possible lawn.

When should I apply it?

lawn-fertiliser

Lawn Fertiliser should be applied to your lawn just after mowing at anytime during the growing season. You will start to see the effects in as little as three days! Before application, make sure there is little possibility of rain or a 30-degree temperature in the days following application. Allow 6-8 weeks between applications for best results.

Quick takeaway

What is lawn fertiliser?

Lawn Fertiliser helps your lawn stay at its healthiest both above and below ground by supplying it with the right nutrients and minerals.

When should I apply it?

Lawn Fertiliser should be applied shortly after mowing, when there is no rain or hot temperatures predicted in the following days. Repeat applications can be done 6-8 weeks after.

What is soil wetter?

soil wetter

Soil wetter is a surfactant that helps to retain moisture in the soil by reducing the surface tension of the water, so it is more easily absorbed.

A soil wetting agent is used to treat hydrophobic soil – dry soil that repels water, causing it to collect on the surface of the soil rather than penetrate through. This is a common issue with sandy soils, potted plants and areas affected by drought. If using organic matter in your soil, or a potting mix, the soil particles can develop a waxy coating, which repels water. If you find when watering your plants that liquid pools on top of the soil rather than being quickly absorbed, then you could have hydrophobic soil. The good news is this problem can be reversed with the use of a soil wetting agent.

Hoselink’s Soil Wetter can be applied to indoor and outdoor pot plants as well as garden beds and can be used in conjunction with our Plant Health Tonic and fertilisers. The unique formula lasts for 12 weeks in the soil and will help the soil retain moisture, reducing the frequency you need to water your plants, saving precious H2O.

When should I apply it?

Soil Wetter lasts for approximately 12 weeks in the soil and is ideally applied before you go on holiday, in the summer months when conditions are usually hot and dry, or as you notice your soil is hydrophobic.

Quick takeaway

When should I apply it?

 

Soil wetter can be applied every 12 weeks, or as you notice your soil is hydrophobic.
