Choosing and using the right fertilizer

How do I know which fertilizer fits my lawn?

Start with a soil analysis — for €49,95 we measure 14 parameters in an accredited lab and send back a personal seasonal plan with exact products, dosage and timing. If you'd rather skip the test, take the 2-minute lawn quiz or email us a photo of your lawn and an agronomist will recommend a programme the same day.

What is the difference between the Basic and Pro lines?

Basic is a balanced, slow-release granular built for homeowners who want a reliably green lawn with minimal fuss. Pro uses the same coated-urea technology we supply to golf courses: a tighter nutrient curve, added trace elements (Fe, Mg) and a finer granule for an even spread. Pro greens up faster and holds colour longer, but both are burn-safe when dosed correctly.

Granular or liquid — which should I pick?

Granulars are your foundation: 6–10 weeks of steady feeding per application, ideal for the main spring and autumn rounds. Liquid Elixirs act within days and are perfect for a quick colour boost, filling the gap between granular rounds, or correcting a specific deficiency. Most customers run a granular base and top up with a liquid mid-season.

Is your fertilizer safe for children and pets?

Yes. Once the granules are watered in and the lawn has dried (roughly 2 hours, or after the first irrigation), the area is safe for children and pets. Our coated granules are designed to dissolve into the soil rather than sit on the surface. We always recommend storing unused product sealed and out of reach.

Will I burn my lawn if I apply too much?

Our controlled-release coating makes burning far less likely than with cheap quick-release fertilizers, but over-application can still stress the grass. Always follow the dosage on the pack (or in your personal plan), spread evenly with a broadcast spreader, and water in afterwards. When in doubt, under-dose slightly — you can always add more.

02 · Orders & shipping

Delivery, tracking and payment

When will my order arrive?

Order before 4 pm on a working day and we ship the same day. Delivery in Belgium and the Netherlands typically takes 1–3 working days. You'll receive a track & trace link by email as soon as it ships. Deliveries to Germany, France and Luxembourg take 2–3 working days.

How much is shipping?

Shipping is free on every order over €75 in BE & NL. Below that, standard home delivery is €6,95 and a pickup point is €3,95. You can calculate the exact cost and choose your delivery method right in the cart before checkout.

Which payment methods do you accept?

Bancontact, iDEAL, Visa and Mastercard. All payments run over a secure, PCI-compliant connection — we never store your card details. Business customers can also request payment by invoice with 30-day terms.

Can I change or cancel my order after placing it?

If your order hasn't shipped yet, email hello@fertilize-it.be with your order number and we'll adjust or cancel it free of charge. Once it's handed to the carrier we can't intercept it, but you can always use the 30-day return window.

03 · Returns & guarantee

Our 30-day promise

Can I return my order?

Yes — every order comes with a 30-day money-back guarantee. Email us with your order number and we'll arrange a pickup label. Unopened packs are refunded in full; for opened packs we refund up to 80% of the purchase price.

What if I'm not happy with the results?

Lawn care is a partnership. If you've followed your plan and aren't seeing progress, send us photos and your application dates — an agronomist will review and adjust the programme at no cost. If we still can't get you there within the season, we'll refund the products.

My pack arrived damaged. What now?

We're sorry about that. Send a photo of the damage to hello@fertilize-it.be within 48 hours of delivery and we'll ship a replacement immediately — no need to return the damaged item.

04 · Soil analysis

How the lab test works

What exactly does the soil analysis measure?

14 parameters in total: pH, organic matter, the key macronutrients (N, P, K), magnesium, calcium, sulphur and the most important trace elements, plus soil texture. The report explains what each result means for your grass and prescribes a corrective seasonal plan — not just a list of numbers.

How do I take a sample?

Your kit includes a corer, a sample bag and a prepaid return envelope. Take 8–10 small plugs from across the lawn, mix them in the bag, and post it back. Full instructions (with photos) are in the box and on the soil analysis page.

How long until I get my results?

You'll have the full report and your personal plan in your inbox within 5 working days of the lab receiving your sample. Need it faster for a project? Ask about our priority service.
