Spring Gardening Prep Checklist — Soil, Weeds, Fertiliser, Lawn & Tools

Spring Gardening Prep — The Complete Step-by-Step Checklist

Spring gardening prep in South Africa begins in August, when soil temperatures start rising and dormant plants begin to stir. Getting every step right — from testing your soil pH to laying down a season-long fertiliser — is the difference between a garden that struggles and one that thrives. This complete spring gardening prep checklist draws on the full GroPlus garden range to walk you through every stage: soil preparation, weed and herbicide control, fertilising, lawn revival, and the tools you need to do it all properly.

Step 1: Test Your Soil Before You Do Anything Else

The most common spring gardening mistake is feeding a garden without knowing what the soil actually needs. Start with the Makhro Soil pH Test Kit — a simple, accurate kit that gives you up to 100 soil tests. SA soils vary dramatically by region: Western Cape soils tend to be acidic, Highveld soils are often neutral to slightly alkaline, and coastal soils can swing either way after winter rains.

• Test pH before any fertiliser, lime, or soil amendment goes down
• Most vegetables and ornamentals thrive at pH 6.0–7.0
• Lawn grasses prefer pH 6.0–7.5
• If pH is below 6.0: add agricultural lime to raise it
• If pH is above 7.5: use a sulphur-containing fertiliser like Multicote 8 (7% S) to gently acidify
• Retest after 4–6 weeks to confirm correction before planting

Checklist: ✅ Test soil pH in lawn, vegetable bed, and flowerbeds separately — they often differ.

Step 2: Soil Preparation — Loosen, Condition, and Feed the Biology

Once you know your pH, prepare the soil for spring planting. Compacted winter soil needs physical loosening and biological stimulation before new roots can establish properly.

• Fork or aerate beds to 15–20cm depth to break winter compaction — use the Gro 3-Piece Garden Tool Set fork for hand-working beds
• Apply Agri-Boost first: the Agri-Boost Liquid Organic Fertiliser 2L delivers earthworm exudate (610g/kg) directly into the soil profile, reactivating microbial life and improving soil structure before any planting begins
• Improve water retention: Makhro Waterwise 3D Granules reduce soil water repellency, ensuring irrigation and rain penetrate evenly rather than running off compacted spring soil

Checklist: ✅ Fork beds ✅ Apply Agri-Boost soil drench ✅ Apply Waterwise 3D if soils are water-repellent

Step 3: Herbicide — Clear Weeds Before They Take Over Spring Beds

Spring weed pressure builds fast. The first warm weeks bring broadleaf weeds, oxalis, and winter annuals that have been germinating through August. Deal with them before you fertilise — feeding a weedy lawn or bed just accelerates weed growth.

Lawn Weeds

The Makhro Super Lawnweeder is a selective herbicide that targets broadleaf weeds in established lawns without harming your grass. It controls dandelion, clover, oxalis, plantain, and most common SA lawn weeds. Apply via the Makhro Pressure Sprayer 2L for even, controlled coverage.

• Apply when weeds are actively growing — late August to early September is ideal
• Do NOT apply in temperatures above 30°C or on drought-stressed lawn
• Wait 4–6 weeks after herbicide before overseeding or turfing
• Do not apply to newly established lawns under 3 months old

Garden Beds

Hand-remove weeds from beds using the Gro fork or trowel before mulching. Avoid broad-spectrum herbicides near ornamentals and vegetables — selective weeding by hand is safest for mixed spring beds.

Checklist: ✅ Apply Super Lawnweeder to established lawn ✅ Hand-weed vegetable and flower beds ✅ Allow 4–6 week post-herbicide window before lawn renovation

Step 4: Fertilising — Feed Every Layer of Your Garden

A complete spring fertiliser programme uses fast-acting liquids for immediate green-up, water-soluble boosters for vegetables and flowers, and controlled-release granules for long-term bed nutrition.

Immediate Liquid Boost — Agri-Boost

Start with Agri-Boost (17:0:0 + Organics). Clip the jug to your garden hose and spray over the entire garden. Covers ±250m² per 2L. Repeat every 2–4 weeks through spring.

Vegetables, Roses & Fruit Trees — Multi-Booster

Follow up with Makhro Multi-Booster, a water-soluble fertiliser enriched with Magnesium. Mix 150g per 5L and apply as a foliar spray using the Makhro Pressure Sprayer. For roses: 25g per large plant every 4 weeks. For fruit trees: 250g per year of age at bud burst.

Flowerbeds & Potted Plants — Multicote 8

Apply Makhro Multicote 8 (15-3-12 N-P-K + full micronutrients) once in early spring and it feeds for up to 8 months. Flowerbeds: 30–60g/m². Pots: 3–8g per litre of medium. Trees: 300g–1kg in the wet zone.

Fish Fertiliser for Soil Biology — Grobest FH100

Makhro Grobest FH100 is a 100% fish hydrolysate with 17 amino acids. Apply as a soil drench or foliar spray every 3–4 weeks to improve soil biology and stimulate root development across all beds.

Checklist: ✅ Agri-Boost whole garden (Week 1) ✅ Multi-Booster foliar on roses/vegs/fruit trees at bud burst ✅ Multicote 8 top-dress beds and pots (Week 3) ✅ Grobest FH100 soil drench every 3–4 weeks

Step 5: Lawn Care — Revive, Feed, and Thicken Before Summer

SA lawns need a deliberate spring programme to recover from winter dormancy and build density before the heat arrives.

• Scarify or rake to remove thatch and dead material — opens the turf for nutrients and air
• Aerate compacted areas by spiking with a garden fork before applying granules
• Apply Groei Power Lawn: Groei Power Lawn 5kg (13-7-10 NPK) at 20–40g/m², spread evenly and water in thoroughly. Covers ±250m² per 5kg bag. Repeat monthly through spring and summer
• Spot-apply Super Lawnweeder for any remaining broadleaf weed patches using the Pressure Sprayer
• Supplement with Agri-Boost every 2–4 weeks for sustained green growth between granule applications
• Use Makhro Lawn Care Super RTU: the Makhro Lawn Care Super RTU 750ml is a ready-to-use combined feed and weed solution for quick spot treatment of patchy or problem areas

Checklist: ✅ Scarify + aerate ✅ Super Lawnweeder on broadleaf weeds ✅ Groei Power Lawn granules (20–40g/m², water in) ✅ Agri-Boost via hose every 2–4 weeks ✅ Lawn Care Super RTU for spot patches
