December Gardening Guide | Gauteng | Stodels Nursery


Get ready to celebrate the magic of December by bringing out the best in your summer garden with our Gauteng December gardening guide. 

Spotlight on: Poinsettia
A bright and cheerful poinsettia makes for the perfect Christmas table centrepiece and will last well beyond the festive season if planted in the garden in a semi-shaded area. These are our tips for selecting and caring for your poinsettia this summer:
  • Select a full and balanced-looking plant that has dark green foliage and is at least two times taller than the pot. 
  • Place in a position that receives at least six hours of bright, but indirect light a day. 
  • Only water when the soil is dry. 
  • Feed with a soluble house plant fertiliser once a month. 
  • Note that extreme temperatures or temperature changes can damage the plant and lead it to lose some of its leaves. 

Plant & Sow Feed
  • Feed garden beds every six weeks with seaweed-rich and organic Atlantic Fertilisers Bio Ocean.
  • Lawns require a 7:1:3 fertiliser such as Atlantic Bio Lawn or Wonder Lawn & Leaf. The latter is chemical-based and will provide faster results, but requires watering three times or more a week to prevent burn.  
  • English gardens in full bloom should be fed with a 3:1:5 fertiliser. A good option is Wonder Fruit & Flower or the organic-based Atlantic Fertilisers Fruit & Flower, which is endorsed by the The Federation of Rose Societies of South Africa.
These are the common garden pests that may plague you this month, and the recommended insecticide: 
  • Whiteflies (use Efekto Whitefly Insecticide) 
  • Mealybug and scale (best treated with Efekto Malasol) 
  • Lily borer (use Protek Knox Worm) 
You can also implement budget-friendly, organic pest busters such as a spray of canola oil or catnip, or use the organic-based Ludwig’s Organic Insect Spray. 


Decorating your summer garden
Since the holiday season is all about entertaining, get your garden into the festive spirit with these creative decorations:
  • Create evening ambience by adding solar lights to pathways, trees and feature plants. 
  • Fairy lights around patio pot plants and hanging baskets will also add sparkle to your festive season. 
  • Consider livening up a dull area under a tree by planting LM Berea lawn (Dactyloctenium Australe)
  • Plant coleus, impatiens and lavender to bring colour to garden beds.
Holiday getaway checklist
Going away this month? Here are some strategies for helping your garden survive the holidays:
  • Move plants in pots and hanging baskets out of direct sun. 
  • Mow your lawn and water it well. Postpone feeding your lawn until you return.
  • Mulch flowerbeds.
  • Pack all gardening tools and outdoor furniture in a safe location.
