A Step-by-Step Guide to Starting Seeds Indoors (2024)

Why start seeds indoors?

One of the most enjoyable aspects of gardening is starting seeds indoors and watching them grow into healthy plants. There are several reasons why this is a good idea. First, starting seeds indoors allows gardeners to get a jump on the growing season. In many parts of Australia, the outdoor growing season is quite short, so starting seeds indoors extends the amount of time that plants have to mature. Second, starting seeds indoors protects young plants from harsh weather conditions, such as strong winds, heavy rains, and damaging frost. By keeping seedlings indoors until they are well-established, gardeners can significantly increase the chances of their survival. Finally, starting seeds indoors gives gardeners more control over the growth environment.

By controlling factors such as temperature, humidity, and light levels, indoor growers can ensure that their plants have everything they need to thrive. In addition, starting seeds indoors can help to protect young plants from pests and diseases.For all these reasons, starting seeds indoors is a great way to get the most out of your garden.

1. Choose yourseedling tray & punnets

When it comes to choosing a seedling tray and punnets, there are a few things to keep in mind.

One is the material. Polypropylene is a durable choice that will last for many seasons. Seed Raising trays made from this material are also easy to clean and disinfect. Another thing to consider is the cell size. Propagation cells come in a variety of sizes, from small plugs to large pots. The size you choose will depend on the type of plant you are growing and the space you have available. Finally, you may want to consider using coir pellets instead of soil. Coir is a sustainable option that offers excellent drainage and aeration, two important factors in successful seed germination. With these considerations in mind, you can choose the seedling tray and punnets that will best suit your needs.

2. Fill your containers with seed raising potting mix

For the best results, fill your seed trays with premium seed raising mix. This premium mix includes river sand, vermiculite, coir, worm castings, and fine-textured compost. The river sand helps to improve drainage, while the vermiculite and coir help to retain moisture. The worm castings provide essential nutrients for young plants, and the fine-textured compost helps to keep the roots protected. By using this premium mix, you will give your seeds the best possible chance of germinating and developing into healthy plants.

3. Sow your seeds

Spring is the perfect time to get your garden started, and one of the most important steps is choosing the right seeds. With so many varieties available, it can be overwhelming to choose which ones to plant. However, there are a few things to keep in mind that will help you make the best decision for your garden.

First, consider what type of plants you want to grow. Do you want flowers, vegetables, or both? Once you've decided on the type of plants you want to grow, research the best varieties for your climate and soil type. The last thing you want is to end up with a failed crop because you didn't choose the right seeds. Once you've selected the perfect seeds for your garden, it's time to sow them. Many seeds need to be started indoors before they can be transplanted outside. This allows them to germinate and get a head start on the growing season. Be sure to provide plenty of light and water, and keep an eye on the temperature. Once your seedlings are ready to transplant, be careful not to damage their roots. With a little time and effort, you'll be rewarded with a beautiful garden that you can enjoy all season long.

4. Water your seeds / seedlings

Seeds need moisture in order to germinate, and once they have germinated, they continue to need water in order to grow. The best way to water at this stage is with a fine spray from a watering can or hose, making sure to keep the seedlings themselves dry. However, it is important to not over-water your seeds. Too much water can damage the seed coat, causing the seed to rot. Once the seed has germinated, it is also important to not let the soil dry out for long. If the soil becomes too dry, it can cause the roots of the plant to die. As a result, adequate watering is essential for growing healthy plants.

5. Place yourseedling tray & punnets in a warm, bright spot

One of the most important things you can do to ensure that your seedlings get off to a good start is to place them in a warm, bright spot. Ideally, the temperature should be between21°C and24°C. If your seedlings are located in a cool or drafty area, they may become leggy and weaker. To avoid these problems, place your tray near a north-facing window or under grow lights.

If they are kept in too dark of an environment, they will become etiolated and thin. However, if they are placed in direct sunlight, they may become overheated and dry out. If you can't provide these conditions yourself, you can always purchase a heat mat specifically designed forseedlings. Just be sure to keep an eye on your seedlings, as they will need to be watered more frequently if they are kept warm. With a little care and attention, you'll be well on your way to a successful gardening season.

6. Keep an eye on your seedlings

When you have taken the time to plant your garden, you want to do everything you can to ensure that your seedlings have the best chance of surviving and thriving. One important step is to keep an eye on them, checking regularly for signs of stress or disease. If you notice any problems, take action immediately to correct the issue. For example, if your seedlings are wilting, they may need more water. On the other hand, if they are turning yellow or brown, they may be getting too much water. Provide plenty of light for your seedlings by placing them in a sunny spot or using grow lights. Once they have grown their first set of true leaves, you can thin out the seedlings so that only the strongest plants remain. By monitoring your seedlings closely, you can head off problems before they have a chance to take root. In doing so, you will give your garden the best possible chance of flourishing.

7. Reap the rewards of starting your own seeds indoors!

Starting your own seeds indoors has many benefits. Not only can you save money, but you can also get a head start on the growing season. In addition, you have greater control over the growing environment, which can result in healthier plants. With a little planning and care, you can reap the rewards of starting your own seeds indoors.
