Despite the cool, mild and gloomy start to Spring we’ve had so far here in our region, summer vegetable seedlings are flooding into garden centres everywhere.

Tomatoes in all your favourite varieties, cucumbers, zucchinis, pumpkins, chillies and capsicums.

Let's not forget these sturdy, healthy and robust, these little seedlings have been given every opportunity for the best head start, germinating in greenhouses with controlled conditions, shielded from harsh winds, extreme temperatures, frosts, pests, and diseases.

So, once we get them home, how do we give them the best chance to thrive and be successful?



Seedling success tips




1. Selection

If you know what day of the week your local garden centre gets their fresh stock in, take advantage of that and go in that afternoon to have the 'pick of the crop' so to speak.

Make sure you choose fresh, healthy strong looking seedlings. Avoid anything that looks sickly, limp, or diseased.


2. Climatise

If you are buying them now, it's still early in the season, consider keeping them inside in a bright windowsill for a few more weeks, then progress them out onto the back porch as the days become consistently nicer, before finally planting them out into the garden. Climatising them gradually can help avoid sending them into shock due the extreme change in environment.


3. Prepare the ground

Before planting them out, prepare the area well. Incorporate lots of organic matter, compost, aged animal manure, some blood and bone. Remember to add gypsum if you have heavier clay soils as gypsum aids drainage.


4. Location

Planting your veggie patch in the right part of your yard can also have a huge baring on its success. Most cropping plants need atleast 6-8 hours of sunlight per day to successfully produce good yields. Pay attention to which side of your house get the beautiful sun most of the day and look to establishing your garden bed there.

If it's not practical to do so or your soil conditions are less than ideal, consider a raised garden bed, or large containers. Using large pots or containers also gives the advantage of being able to move them from one location to the next if need be.


5. Timing

Plant your seedlings early in the day when the weather is nice, sunny and mild, so they have time to acclimatise before the cold and damp of the evening sets in.


6. Handle with care

Like all babies, they're fragile, handle them with care. Avoid damaging or disturbing their delicate root systems. Don't be tempted to try and separate the likes of spring onions or carrots, leave them be, they will sort themselves out (survival of the fittest) you can remove any smaller struggling ones as they begin to mature.


7. Support

Some vegetables love to climb, peas, beans, cucumbers and indeterminate varieties of tomatoes. Make sure you provide them with a stake or trellis to help support them as they grow.

8. Frost prevention

Monitor the weather forecast and have a survival plan in place. This probably sounds silly, but in reality, it's not! Spring always sees multiple nasty frosts here in our region, not to mention days of hot Northerly winds. A good frost will wipe out your vegetable patch in one night, so cover them up with frost cloth, some containers or milk bottles, or whatever you have available.


9. Hydration

Always water your new seedlings in well with a solution of Seasol Health Treatment, looking for air bubbles to confirm they're watered thoroughly and there are not dry spots in their soil at the root zone.

Adding Seasol health Treatment helps avoid transplant shock, boosts the plants immune system and stimulates the roots to get growing.

Be consistent with your watering rescheme, if you're not consistent a whole host of issues can arise. Stunted poor growth, wilting, shrivelled small fruit and even split skins.


10. Nutrition

Feed feed feed!! would your kids grow on an empty tummy? no, and neither will your seedlings. Feed weekly with a readily available soluble fertiliser high in nitrogen for foliage development such as Seasol Powerfeed, alongside a slow-release organic fertiliser such as Neutrogs Rapid Raiser. As your plants reach maturity and change to reproductive Potassium becomes important for fruit and flower development, so look for that branded Potash, such as Yates liquid Potash.

11. Mulch

Mulch generously around your little seedlings with some Rocky Point Sugarcane, it's a nice fine chopped up mulch that will pack neatly in and around them. Mulching not only insulates them, aid in water retention and prevent dehydration, but as it breaks down it continues to feed your soil.


12. Pest & Disease Prevention

Finally, be vigilant and constantly on the lookout for pests, diseases and disorders. Hungry slugs, snails and earwigs will devour seedlings almost overnight, powdery mildew and rust are common fungal infections that will require a fungicide, and plants that generally look sad and aren't performing well, may have issues with inconsistency of water availability or even toxicity. If you're unsure, you're always welcome to contact me for more advice, or if you live in my neck of the woods...you'll most likely know where to find me 😜🪴


Without a doubt, if your taking onboard and implementing these 12 tips, you're going to be rewarded with a bountiful patch full of fresh produce to keep you going all season and perhaps even enough to share around with friends and family, there's nothing more rewarding!

Have a wonderful weekend and enjoy your gardens. 😘🌸🌱

Frosts are among the greatest adversaries for gardeners throughout the colder months. Days with clear, sunny skies often lead to subzero temperatures overnight, causing frosts to occur. Without being pro-active and having measures in place, the results can be detrimental.

Talk to any wise old gardeners in our community and they'll tell you to hold off until the October Show weekend to plant your tomatoes. I'm not entirely certain, but I'm pretty sure it has a whole lot less to do with Dippy Dogs and Fairy Floss and more to do with the soil temperatures and frost risks.



With Spring now in full swing and summer vegetable seedlings going into the ground left right and centre, powdery mildew becomes a hot topic. If you're vigilant and know what to look out for, and perhaps even what precautions to have in place, you'll be able to act quickly if it does show up for the party!
