Seed planting containers come in all shapes and sizes but the only absolute requirements are that they are clean and have proper drainage holes. Last week I set myself the challenge that each day, for one week, I would make a seed tray or pot using a household item, that would have otherwise been thrown away (I know, my family are starting to worry about me and my sowing and growing obsession).
Milk or fruit juice cartons make excellent seed trays. After washing an empty oat milk carton, I used a craft knife to cut off the top and then make some drainage holes in the bottom. I sowed some snapdragons and five days later they were starting to germinate.
Plastic containers that supermarket fruit and veg come in are ideal and easy to make into a seed tray. Some already have drainage holes in the bottom but I needed to add a few to mine. The malope I sowed was starting to show after only 3 days.
Using 3 layers of old newspaper I drew a 24cm square and then divided it further into thirds vertically and horizontally. I made four cuts along the dotted line and assembled it into a box shape using recyclable tape. These, when the flowers are ready for planting out, can be planted directly into your cut flower patch.
At last a way to stop plastic milk bottles ending up in landfill. Again, after washing, I used a craft knife to remove the side and to make drainage holes in the bottom.
The trusty yoghurt pot (or in our case the trusty fruit fool pot), simply wash thoroughly and add drainage holes.
Toilet roll inners are perfect for flowers like sweet peas which have long roots. I was also thinking I might try using these for seeds like zinnia which don't like root disturbance, will have a go and keep you posted.
Day seven and the last day of my challenge and I was seeing potential seed trays and pots everywhere. I couldn't choose between the egg box, the plastic chocolate éclair packaging, the metallic lined vegetable stock container or the plastic dried ingredients jar. Just a good excuse to sow a few more seeds, I think!
