I want to start growing flowers by seed but I am a novice. I have a seed tray with venting holes but it doesnt
say how to use them. Please help??
Hello Colleen, seed trays with venting holes (or slits or ridges) are designed to allow for a more natural root system - and you can use them in the same way you would use a regular seed raising tray. Holes/slits are also there to allow for drainage and air-circulation which can assist in reducing the chance of fungal issues like damping off.
Use them as you would regular seed raising trays - simply fill with a good quality seed raising mix (like "Yates Seed Raising Mix", which you can find more about here: https://www.yates.com.au/yates-6l-seed-raising-mix/), and follow the instructions on the pack as to how deep to plant your seeds, or any other special instructions (eg: they need to be cold stratified, heat treated first etc). Most seeds you purchase from a nursery, you can simply sprinkle across your mix, lightly cover with your seed raising mix, and water in! Keep in a warm spot, and keep moist (don't allow them to dry out).
