Potchefstroom’s spring and summer months bring intense heat and strong sunshine, creating challenges for local gardens. On the hottest days, temperatures here can soar to around 37°C, and while summer rains provide relief, the intervals of harsh sun can quickly dry out lawns, vegetable patches, and flower beds.

To help your garden thrive through Potch’s hot spring and summer, here are practical tips on watering, soil care, shading, and smart use of resources, including local products from Build It Potchefstroom - all tailored to our North West climate.
Watering Schedules: When and How to Water Wisely
Water early in the day: Timing is everything. Plan to water during the cool early morning hours (around 4–6am), before the sun is high. This allows moisture to soak deeply into the soil before the day’s heat causes rapid evaporation.
Early watering also helps prevent fungal issues that can arise if plants stay damp overnight. If mornings are not possible, late evening after sunset is second best but avoid wetting foliage at night to keep fungus at bay.
Water deeply, but infrequently: Instead of daily light sprinklings, give your lawn and garden a thorough, deep soak a couple of times per week. The “deep and infrequent” approach trains roots to grow deeper into the soil, making plants more drought-resistant.
Aim to apply about 25 mm (2.5 cm) of water per session (that’s roughly the amount needed to wet the soil to a depth of 20–30 cm) for lawns and flowerbeds. In practice, this might mean watering once or twice a week if there’s no rain.
Deep watering encourages robust root systems so your grass and plants become “athletes” that withstand heat, rather than shallow-rooted “weaklings” prone to wilting.

Adapt for lawns vs. veggies: Lawns typically do well with a deep weekly watering, you can even measure 2–3 cm of water by placing a cup under your sprinkler.
For vegetable gardens, check soil moisture more frequently; shallow-rooted veggies may need water 2–3 times a week, but still focus on deep soaking the root zone rather than surface spraying. Using a soaker hose or drip irrigation system in veggie beds is ideal, as it delivers water right to the roots without waste.
Build It Potchefstroom stocks hoses, sprinklers and even basic drip irrigation kits to help you set up an efficient watering system, a smart move to ensure every drop counts in the summer heat.
Conserve water with smart tech: Consider investing in water-saving irrigation tools. Simple hose timers, drip lines, or spray nozzles with adjustable flow can cut down on water use by ensuring you only water as needed.
In fact, modern smart irrigation systems (like drip systems with timers or rain sensors) can reduce water usage by up to 50% while keeping plants healthy.
Also take advantage of any summer showers, set out a rain barrel or JoJo tank to collect rainwater which you can reuse on dry days. With Potchefstroom’s summer thunderstorms, a properly placed water tank can harvest hundreds of liters of free water for your garden.
Conditioning Your Soil with Compost and Mulch
Hot weather can wreak havoc on soil moisture. The key to resilience is improving your soil’s water-holding capacity and fertility:
Add compost for healthy soil: Work organic compost into your garden beds and even top-dress your lawn in spring. Compost enriches the soil with nutrients and improves its structure, helping sandy soils hold moisture and clay soils drain better.
Healthier soil means roots can grow deeper and access water more readily, which is vital in hot conditions. You can pick up bags of quality compost or lawn dressing at Build It Potchefstroom to give your soil a boost.
The store’s garden section carries rich potting soil and fertilizers too, so you can feed your flowers and veggies for strong growth. Just remember not to over-fertilize in peak heat, a slow-release fertiliser applied in early spring is gentler, letting compost do the work of feeding plants over time.

Mulch to lock in moisture: Mulch is your garden’s best friend in summer. A thick layer of organic mulch (such as bark chips, straw, dry grass clippings or even wood compost) spread on top of your soil acts like a protective blanket.
It dramatically reduces evaporation , a 5–7 cm layer of mulch can cut water loss by up to 70%, and insulates the soil from extreme heat. By shading the soil, mulch keeps plant roots cooler and prevents the sun from baking the ground. It also suppresses weeds (which compete for water) and slowly adds organic matter to the soil as it breaks down.
Spread mulch around the base of plants in flower beds and veggie gardens, being careful to keep it a few centimeters away from stems to avoid rot. For lawns, you can even leave finely cut grass clippings on the lawn (“grasscycling”) as a light mulch to retain moisture. And if you need mulch materials, Build It Potch often has bark chips or wood mulch in stock, as well as garden tools like rakes and wheelbarrows to help you apply it.
Shade and Protect Your Plants from Scorching Sun
When the African sun beats down in mid-summer, providing some relief from direct sunlight can save your plants from heat stress. Potchefstroom enjoys over 12 hours of intense sunshine per summer day, and UV levels can be extreme, so thoughtful shading is a must.
Use shade netting or cloth: Erecting a simple shade cloth can drop the temperature for sun-sensitive plants by several degrees. Shade netting (available from local hardware suppliers) can be draped over veggie gardens or young flower beds during heatwaves.
For example, a 40–50% shade cloth still lets through enough light for growth but protects tender leaves from scorching. Build It Potchefstroom can supply shade cloth by the meter - set it up on poles or a DIY frame over your vegetables like tomatoes, lettuce, and spinach to shield them during the harsh midday sun.
Even a temporary structure with stakes and cloth during a heatwave can make the difference between wilting and thriving veggies. Remove or roll up the shade cloth in late afternoon to let plants enjoy cooler evening sun.
Strategic planting for shade: Plan your garden layout to naturally protect more delicate plants. Group taller or bushy plants such as sunflowers or corn on the west/north side of lower-growing veggies so they provide a “living shade corridor” and break the force of the afternoon sun.
Similarly, use trellised vines or climbers (like granadillas or climbing beans) to cast dappled shade on beds below. Over time, consider planting a hardy shade tree or two in your yard for long-term relief (just be mindful of root competition). In containers, simply move potted plants to a shaded patio or under an overhang during heatwaves, a little break from direct sun can prevent leaf scorch.
Protect the lawn from extreme sun: Grass loves sun, but in extreme heat your lawn can get patchy “burn” spots. If possible, provide occasional shade for lawn areas during peak sun – even a portable gazebo or market umbrella on the worst afternoons can help a prized patch of grass recover.
More practically, keep your mower on a higher setting in summer so the grass blades are a bit taller. Taller grass shades its own roots and soil, keeping them cooler and more moist. For Kikuyu or other common grasses, aim for about 5–7 cm height in summer. Also avoid mowing in the heat of midday; cutting grass in cooler morning/evening hours is gentler on the turf.
Choose Heat-Tolerant, Water-Wise Plants
One of the best strategies for a low-maintenance summer garden is to grow plants suited to our climate. Indigenous and drought-tolerant species naturally withstand heat and need less water.
Water-wise lawn and flowers: If you are planting or re-seeding a lawn, opt for heat-resilient grass varieties like Kikuyu, Buffalo, or Bermuda grass, which are well adapted to South Africa’s hot summers.
These grasses tolerate high temperatures and bounce back better from drought, reducing the risk of brown lawns. For flower beds, incorporate hardy perennials and natives. Many South African indigenous flowers and shrubs have evolved to thrive with minimal water.
For example, aloes (with their fleshy, water-storing leaves) and succulents like Spekboom (Portulacaria afra) add beauty and greenery while shrugging off heat. Indigenous wildflowers such as Gazania or Pelargoniums (geraniums) deliver bright blooms and are built for our climate. These local heroes know how to make the most of every drop of water, and as a bonus, they often attract birds and butterflies to your garden.
Hardy veggies and herbs: Summer veggies that can handle heat include crops like cherry tomatoes, peppers, eggplant, squashes, sweet potatoes, and amaranth (tebbe spinach), which generally tolerate strong sun if kept watered.
Plant herbs like rosemary, thyme, or oregano which love sun and dry conditions. Leafy greens and lettuce will need more coddling; try planting them in partial shade or under shade cloth to prevent bolting. Always check seed packets or nursery info for heat tolerance and consider planting a little earlier or later in the season for the most sensitive crops.
Build It Potchefstroom often carries seasonal seeds and seedlings suited for the Potch climate, so you can ask their staff for recommendations on heat-tolerant varieties. By choosing resilient plants, you’ll spend less time watering and worrying, and more time enjoying a vibrant, hardy garden that withstands the summer sun.

Eco-Friendly, Local Solutions for Garden Care
Keeping your garden happy in the heat doesn’t mean you have to use tons of water or harmful chemicals. Potchefstroom gardeners can adopt eco-friendly practices and find what they need close to home.
Mulching and composting are natural ways to conserve water and improve soil without chemical additives. Using a drip irrigation instead of a sprinkler, or a simple rain-harvesting tank, helps reuse and save water sustainably.
Even fertilizing can be done the green way for instance, adding organic compost or manure improves soil gradually, and using organic fertilisers (like locally-made GuanoBoost or slow-release pellets) avoids the risk of “burning” plants in extreme heat.
The good news is you can find all the supplies for these practices right here in town. Build It Potchefstroom’s garden section is a handy source for quality gardening materials and tools to implement these heat-beating strategies. For example, you can pick up durable watering gear like hoses, sprinklers, spray nozzles and connectors to upgrade leaky old equipment.
They stock irrigation essentials from hose fittings to drip irrigation kits ,making it easy to set up a water-efficient system for your lawn or veggie patch. To improve your soil, you’ll find bags of compost, topsoil, and fertiliser ready to revive dry garden beds. Need to add mulch? Look for bark chips or straw bales, or use the compost as a moisture-retaining top layer.
If you’re planting anew, check out their selection of seeds and seedlings chosen for the Potchefstroom climate, you might discover heat-tolerant flower seeds or vegetable varieties perfect for our region.
