What to Plant in March: Veggie Patch Essentials
When it comes to planting, March is one of the more cooperative windows. Soil is still warm enough for roots to establish quickly, and the cooler air temperature is easier on new growth.
Cool-season vegetables such as broad beans, snow peas, silverbeet, spinach, spring onions and beetroot all perform well now. These crops prefer steady moisture, so if the soil has become dry or water-repellent after summer, deal with that before planting rather than trying to compensate later.
A treatment of Seasol Super Soil Wetter & Conditioner, followed by a thorough soak, helps water move into the root zone instead of heading off on its own agenda. If your beds feel a bit spent, incorporating compost or Seasol Liquid Compost improves soil condition and gives new plantings a steadier start.
Before planting seedlings, soak the root ball in diluted Seasol (40 mL per 9 L) until bubbles stop rising. This ensures the root zone is fully hydrated and reduces transplant stress. It takes a minute and saves a week. Water in with the same solution and repeat about a week later, while roots settle.
March also suits onions, garlic, shallots, sweet peas, salvias and plenty of native plants. Few months offer this many dependable options, so it’s worth taking advantage of!
Best Flowers & Shrubs to Plant in March
Hardy ornamentals establish well this month because warm soil encourages root growth while cooler air keeps foliage from working too hard. Lomandra, westringia, lavender and salvias are all reliable choices now.
If you’re refreshing a garden bed, improving the soil beforehand makes planting easier and reduces watering demands. Compost or Seasol Super Compost improves structure so roots can move through soil more freely and access moisture more evenly.
Late-summer bloomers like dahlias, penstemons, chrysanthemums and Michaelmas daisies often keep going with very little encouragement. Removing spent flowers and tidying growth is usually enough to keep plants looking good without heavier pruning or feeding.
How to Repair Your Lawn in March
By March most lawns show signs of summer use. The good news is that they usually respond well now while soil is still warm enough to support active root growth. If you act early in the month, results tend to show up faster than people expect.
Setting the mower a little higher protects new growth and keeps the soil shaded. Deep watering encourages roots to grow downward rather than lingering near the surface. If your lawn feels compacted or spongy underfoot, raking out thatch or lightly aerating helps water and air move through properly again.
Bare patches should repair well now. Loosen the soil, sow lawn seed and keep it evenly moist while it establishes. Watering in with Seasol Lawn & Turf Starter supports early root development and helps new grass fill in evenly rather than in scattered tufts.
Compacted or uneven sections can be improved with Seasol Lawn Top Dress Mix, followed by Seasol for Lush Green Lawns to support recovery and even out colour. In cooler regions, it helps to do this earlier while the soil is still warm enough to cooperate.
March Garden Problems to Keep an Eye On
Early autumn usually brings a few familiar issues; however, most are straightforward if you deal with them early.
Sooty mould usually develops after sap-feeding pests such as aphids or scale have been around. Treat the insects first using EarthCare White Oil Insect Spray, then apply Seasol to support fresh, clean growth.
Powdery mildew commonly appears when plants are under stress, especially where moisture levels fluctuate or airflow is limited. Removing affected leaves, improving airflow and watering earlier in the day usually keeps it contained. If soil moisture has been uneven, Seasol Super Soil Wetter & Conditioner can help stabilise things.
General summer fatigue is also common. Some plants simply look tired after extended heat. Deep watering, improved soil and a dose of Seasol is often enough to steady them so they keep going through autumn.
Indoor Plant Care for Early Autumn
Indoor plants usually show how they felt about summer. A bit of stretched growth, uneven foliage or dry tips is fairly standard. March is a sensible time to reset things so they head into autumn looking more composed.
Move plants slightly back from bright windows, wipe leaves clean so they can photosynthesise properly and check drainage so excess water doesn’t sit around roots. Let the surface of the potting mix dry slightly between watering rather than watering to a fixed routine.
A light feed with PowerFeed Indoor & Potted Plants supports steady new growth, and occasional use of Seasol Foliar Spray can help plants recover, particularly where indoor air has been dry. As light levels soften, growth usually evens out.
