Expert Advice: How to Grow Woolworths Discovery Garden Plants

Is your kitchen window sill about to bristle with Woolworths Discovery Garden pots? Take note of some handy tips and troubleshooting from a gardening expert, so your fundraising efforts (and dollars) don’t go to waste.

Woolworths Discovery Garden is back from Wednesday, February 10. The promotional campaign allows buyers to receive a seedling kit for every $ 30 they spend.

There are 24 different seeds of vegetables, herbs and flowers to harvest: scallion, cabbage, carrots, cherry tomatoes, lettuce, spinach, silver beet, red basil, chives, thyme, oregano, lemon balm, sage, blueberry, salvia , dianthus, phacelia, lavender, poppy, aster, zinnia, pansy and Swan River daisy.

Woolworths relished the good green vibe when the supermarket chain first launched the Discovery Garden campaign in 2019, saying it hoped the promotion would inspire a new generation of green thumbs. This cycle aims to encourage pollination through seedlings that attract bees.

To help you get the most out of your collection efforts, take note of the lessons learned on the first tour of Discovery Garden when Canstar asked Bunnings gardening expert Mill Wallasvaara to help resolve some of the potential pain points.

I have collected a lot of Discovery Garden Seedling Kits – should I try to germinate them all at once?

If you have a small yard or balcony, it’s a good idea to stagger edible seed plantings a bit so you can harvest them over longer periods. However, if you have a more spacious garden or a lot of pots to plant them in, you can plant them all at the same time. Flower seedlings in particular can look great when planted all together and in bloom.

How do I determine which Discovery Garden seeds to plant now?

Take a look online or in a good gardening book to see what the best time of year is for each type of plant.

My Discovery Garden Seedling Kits have germinated – what should I do with them now?

Once your seeds have germinated, the seedlings should be planted in a pot or garden bed so that they can continue to grow and flourish.

How do I know when my Discovery Garden seedlings are right to plant in the ground or in a pot?

When the seedlings have sprouted and opened their second set of leaves, they are large enough to be planted elsewhere. Keep an eye out for snails as they love to eat fresh seedlings.

Some of my Discovery Garden seedling pots have mold. How can I deal with this? Is it good to plant them like that?

Organic pots will develop mold if they get wet and don’t flow freely after being watered. Try moving the seedlings to a sunnier position like a window sill and let the pots drain freely so they don’t sit in a saucer of water. It’s okay to plant pots with mold in them, as organic pots will decompose in the soil over time anyway.

Should I feed my Discovery Garden seedlings?

Once the seedlings have grown their second set of leaves, they will begin to need fertilizer. When planting, use a granular fertilizer or a slow release fertilizer mixed with the soil. If you are using top quality potting soil, this will not be necessary as the fertilizer is already included in the mix. Just be sure to follow the directions on the package, as using too much can damage the young plants. Alternatively, a liquid fertilizer can be used once or twice a week, but again, be sure to follow the directions.

How often should I water my Discovery Garden plants?

Herbs and vegetables require regular watering. How often varies depending on the position they are in (for example, whether they are potted or planted in the ground and the type of soil). Typically, herbs and vegetables will require daily watering to keep them growing. The best way to check if the plants need watering is to put your finger in the soil – if it’s wet, the plants are happy. However, you don’t want soggy soil either, so make sure your herbs and vegetables have plenty of drainage.

Fruit plants (and trees) also require regular watering and again, the frequency will vary depending on the position they are in. However, if you have good quality soil (which contains good organic matter and good water holding capacity), deep watering (making sure the root system is completely soaked) once or twice a week. will suffice in most cases. Deep watering is best because it encourages the roots to grow up to the soil profile to access available water away from the soil surface, which can dry out quickly.

Water saving tips for gardeners:

  • Add organic matter: Adding organic matter such as compost or rotten manure can help the soil retain more moisture and provide nutrients for your plants to grow.
  • Add mulch: It can help your plants retain water and prevent weeds. This is important because weeds compete for water and nutrients with your plants and can also attract unwanted pests. Sugarcane mulch or pea straw is especially good for vegetables, herbs, flowers, and fruit plants as it helps suppress weeds and retain water, as well as rot over time. , which increases organic matter in the soil.
  • Use pots or planters: In very dry parts of Australia, growing herbs, vegetables, and flowers in pots or planters is a great way to manage watering. Using a top quality potting soil is also preferable, as all the nutrients needed to achieve a good result are already included. Add mulch to the soil of your plants to help keep the potting soil moist and a saucer to catch runoff water.
