Old fashioned gardening tips that still work wonders

In a world of smart sprinklers and app-controlled greenhouses, there’s something deeply satisfying about returning to gardening methods that have stood the test of time. Our grandparents and great-grandparents didn’t have fancy gadgets or synthetic chemicals, yet they managed to grow flourishing gardens that fed families and brightened homes.

These old fashioned gardening tips aren’t just nostalgic – they’re often more sustainable, budget-friendly, and surprisingly effective. Here are 10 old-fashioned gardening gems that modern gardeners are rediscovering with amazement.

Companion Planting: Nature’s Perfect Partnerships

Long before commercial pesticides, gardeners knew that certain plants protect each other when grown together. Native Americans practiced the “Three Sisters” method – planting corn, beans, and squash together. The corn provided a trellis for beans, beans fixed nitrogen in the soil, and squash’s broad leaves suppressed weeds and retained moisture.

Try planting marigolds near tomatoes to repel nematodes and other pests, or nasturtiums near cucumbers to draw aphids away from your valuable crops.

Coffee Grounds: The Overlooked Garden Gold

Your morning coffee ritual can benefit your garden tremendously. Our ancestors saved coffee grounds religiously, knowing their value. Rich in nitrogen, phosphorus, and potassium, coffee grounds make exceptional fertiliser, especially for acid-loving plants like azaleas, blueberries, and roses.

Used carefully and in moderation, coffee grounds can be a valuable addition to your garden. They’re rich in nitrogen and also provide smaller amounts of phosphorus and potassium—key nutrients that support healthy plant growth. As a bonus, they add organic matter to the soil, making them a useful ingredient in compost or as a light mulch around many types of plants.

Simply scatter used grounds around plants, add them to compost, or make a “coffee tea” by steeping grounds in water overnight for a nutrient-rich plant drink.

Eggshells: Calcium Powerhouses

Before commercial calcium supplements, gardeners crushed eggshells around plants to prevent blossom-end rot in tomatoes and strengthen plant cell walls. They also used half shells as biodegradable seed starters.

Crushed eggshells also create a sharp barrier that slugs and snails won’t cross, protecting tender seedlings without harmful chemicals.

Newspaper Mulch: The Original Weed Barrier

Long before plastic landscape fabric, gardeners used layers of newspaper to suppress weeds and retain soil moisture. Unlike synthetic barriers, newspaper breaks down over time, adding organic matter to the soil while allowing water and nutrients to pass through.

Apply 4-8 sheets thick around plants, wet thoroughly, and cover with a thin layer of compost or mulch to keep it in place and improve appearance.

The Moon Planting Calendar

Our ancestors planned their gardening by the moon’s phases, a practice now supported by science. The moon’s gravitational pull affects soil moisture, and certain activities align with lunar cycles:

• Plant above-ground crops during the waxing moon (increasing light)
• Plant root crops during the waning moon (decreasing light)
• Harvest during the full moon when moisture and energy levels peak
• Prune during the new moon to minimize sap loss

Soap Spray Pest Control

Our great-grandmothers made simple insecticidal soap using household items. This gentle yet effective spray controls aphids, mites, and other soft-bodied insects without harming beneficial creatures or leaving harmful residues.

Mix 1 tablespoon of pure castile soap (like Dr. Bronner’s) with a quart of water. Spray directly on pests in the early morning or evening, avoiding the heat of the day.

Compost Tea: Garden Vitamins

Before synthetic fertilizers dominated garden centers, gardeners brewed “compost tea” – a liquid fertilizer and natural disease fighter. This microbe-rich solution strengthens plants’ immune systems and adds beneficial organisms to the soil.

Fill a burlap bag with finished compost, suspend it in a bucket of water (like a giant tea bag), and let it steep for 2-3 days. Dilute the resulting brown liquid 1:10 with water and apply to soil or as a foliar spray.

Human Urine Fertilizer

While it might sound shocking today, using diluted human urine as fertilizer was common practice in traditional gardens. Modern science confirms our ancestors’ wisdom – urine is sterile (from healthy individuals) and contains nitrogen, phosphorus, and potassium – the same NPK in commercial fertilizers.

Dilute fresh urine 1:10 with water and apply to soil (not directly on plants). This works especially well for heavy feeders like corn and squash.

Buried Treasures: Targeted Deep Nutrition

Before time-release fertilizers, gardeners buried specific items under plants to slowly release nutrients exactly where needed:

• Fish heads under tomato transplants (Native American technique)
• Banana peels under roses for potassium
• Crushed animal bones under fruit trees for phosphorus
• Wool scraps under perennials for slow-release nitrogen

These decomposing materials feed plants gradually throughout the growing season. We now know this as part of the biodynamic gardening approach.

Brush Pile Season Extension

Before plastic hoop houses and row covers, gardeners used simple brush piles to protect tender plants from frost. Gathering pruned branches and twigs in a loose pile over plants creates air pockets that trap heat and prevent frost from settling.

This works especially well for protecting fall crops during the first light frosts, often extending the harvest season by weeks.

These time-honoured techniques remind us that effective gardening doesn’t require expensive products or complicated technology. The wisdom of generations past can help us grow healthier gardens while treading more lightly on the earth.
