What Seeds To Plant In December

December rolls in with that warm, lazy feeling of early summer, but the garden certainly isn’t slowing down. 🌞 Everything is growing with purpose now. Vines stretch a little further each morning, herbs fill the air with scent, and fruiting plants settle into their stride. It’s the time of year when your patch really starts to feel abundant, and all those little efforts from earlier in the season begin to show their rewards. 🌿

🌼 A Full and Fruity Month
Hopefully you’ve already tucked in plenty of summer vegetables by now, but don’t worry if a few spots are still waiting for something special. December is forgiving. It’s not too late to sow more warm-season favourites, especially if you’re already enjoying some early harvests. A second round of zucchini or cucumbers will keep the kitchen well supplied, and another tray of basil, lettuce, capsicum or beans will fill any gaps and keep the momentum going.

The heat is rising, so keep an eye on moisture levels. Containers and raised beds dry out quickly once the sun gets going. A fresh layer of mulch will help keep the soil cool and stop water evaporating too fast. It’s a simple job that pays off right through summer.

🌻 Summer Colour and Cheer
This is a lovely month to brighten the garden with flowers that thrive in the warm weather. Try sowing zinnias, cosmos and marigolds to carry that festive feel straight through the holidays. They grow fast, attract plenty of pollinators, and give your garden that happy, lively look that suits long summer evenings outdoors.

🐝 Keep It Moving
Succession planting is your friend now. Pop in new seedlings every couple of weeks so you have fresh pickings coming right into autumn. Herbs like parsley and chives take well to regular planting, and heat-lovers such as pumpkins, eggplants and chillies will still settle in nicely as the warm days continue.

Pests can be a bit cheeky this time of year. Aphids, whitefly and caterpillars can appear almost overnight. A gentle spray of soapy water or letting the ladybirds do their work usually keeps things under control. 🐞

🌱 Enjoy the Abundance
Between the watering, picking and sowing, take a moment to enjoy your space. Sit in the shade for five minutes, listen to the bees hum around the flowers and feel that quiet satisfaction of a garden that’s truly alive.

Keep up the good work. Even with the heat building, there’s still plenty you can sow and plenty to enjoy. December is all about keeping the rhythm going while soaking up the joy of the season. 🌸✨
