"My lawn used to go backwards every summer no matter what I tried. Two boxes into Seasonal Care and it's stayed thick and green right through the hot spell that normally wrecks it. Ten minutes with the guide each time, nothing to remember, nothing to guess. Wouldn't go back to buying products one at a time."

Spring Box (March–May)
GROWTH granular fertiliser + BOOST liquid seaweed biostimulant. Pushes fresh growth after winter, strengthens roots, prepares the lawn for the growing season.
Summer Box (June–August)
BOOST liquid biostimulant + GROWTH maintenance formulation. Protects colour, improves drought tolerance, keeps grass strong through heat and heavy use.
Autumn Box (September–November)
GROWTH autumn formulation + BOOST. Strengthens roots before winter, repairs summer wear, prepares the lawn for dormancy.
Winter Box (December–February)
POWER liquid iron + BOOST. Maintains colour through the coldest months, suppresses moss, keeps the lawn visually strong even in slow-growth conditions.
Exact contents vary slightly by season and lawn size. Every box includes a step-by-step guide.
A lawn treated once and then ignored goes backwards. The grass that looked great in May becomes patchy by August if it doesn't get what it needs through summer. And a lawn that's neglected in autumn struggles again come spring.
Consistent seasonal care is the difference between a lawn that maintains its results and one that needs transforming again every year. That's what Seasonal Care is designed to prevent.
Open the box. Follow the guide. Apply in order. Done.

Your lawn needs something different every three months. Each box is matched to exactly what the season demands, then the cycle starts again.
Winter leaves roots weak and colour patchy. GROWTH and BOOST rebuild strength and push fresh growth before the season gets going.
Heat and heavy use wear a lawn down faster than any other season. BOOST and GROWTH hold colour and resilience through the driest stretch of the year.
Summer wear needs repairing before winter sets in. GROWTH's autumn formulation strengthens roots while BOOST helps the lawn recover.
Moss and dull colour take over once growth stops. POWER suppresses moss and holds colour through the slow months, with BOOST keeping roots active.

GREENER Seasonal Care
Garden centre products
Professional treatments
Start with the GREENER Transformation Kit to repair patchy areas, improve colour and build a thicker, healthier lawn.
GREENER Seasonal Care delivers the right treatments every season to help maintain lawn health, colour and thickness long-term.
Consistent seasonal lawncare helps keep your lawn healthier, greener and stronger throughout the seasons.
Designed as one simple lawncare system, without the guesswork.
Each box contains professional-grade seasonal treatments formulated for the time of year — typically a combination of granular fertiliser, liquid biostimulant and, in winter, liquid iron. Exact contents vary by season and lawn size. Every box includes a step-by-step application guide.
You subscribe once and receive a seasonal delivery every 3 months — automatically timed to arrive before the start of each new season. Each box contains the right treatments for that season, matched to your chosen lawn size. You apply them in under an hour and GREENER handles the schedule.
Yes — cancel, pause or skip any delivery directly from your account with no penalty. There's no minimum term and no cancellation fee. You're in complete control.
Don't worry — just apply at the next opportunity. The seasonal treatments are flexible enough to work across a reasonable window. If you're unsure, contact us and we'll advise on the best approach for your lawn's current condition.
Not necessarily. If your lawn is in good condition and you want to maintain it, Seasonal Care works as a standalone maintenance plan. If your lawn is patchy, thin or struggling, we'd recommend starting with the Transformation Kit first to get the results you want — then maintaining them with Seasonal Care.
Every seasonal delivery is covered by the 60-Day Lawn Pledge. Follow the guide, apply in order, water it in. If you don't see visible improvement within 60 days — full refund. No returns. No questions asked.
Your first box is dispatched within 1–2 working days of ordering and delivered via tracked UK courier. Subsequent deliveries arrive every 3 months from your subscription start date.
Yes — contact us at any point and we'll update your subscription to the correct size for your next delivery.
Every season without the right treatment is a season of slow regression: colour fading, patches returning, the results you worked for gradually disappearing.
Under £3 a week. Cancel any time. 60-Day Pledge on every box.
