Having a ready supply of Spring onions in your home makes it easy to enhance many a meal. They especially go well with baked potatoes. Here's how to regrow your own from purchased spring onions so you have a ready supply to use whenever required. They are surprisingly easy to re-grow.

Supplies

Step 1: Preparation

Select spring onions which still have roots attached.
Cut the base off about an inch and a half from the bottom.
Place is water for three to four days to promote stem growth.
Plant out into soil.

Step 2: Cooking Ideas

Spring onions can be used to add flavour and texture when cooking. They are great when added to mashed potatoes

Adding spring onions to a baked potato, along with a dob of butter, turns the dial up to eleven.

Step 3: Planting

Planting is easy, just poke a hole into the soil, insert the roots, cover with soil and give some water. I am growing them in a planter box attached to the inside of my balcony railing.

Step 4: Cut Too Short

These spring onions were cut too close to the base when planted out. These ones will take longer to grow (if at all) than if 1 - 1 1/2 inch of stalk had been left.

Step 5: Kick Start the Growth

To make the spring onions sprout quicker, after cutting about an inch and a half from the base, place in water to promote growth. The photos show growth after 1 day and 5 days. After 3-5 days, plant into soil. As can be seen - if they are cut at the very bottom, regrowth will take considerably longer.

Step 6: The Difference When Cut Too Short

Here's the difference after 10 days. The ones cut too short are only just starting to grow. While the ones cut an inch and a half from the base and then soaked in water for 5 days before planting out are well on their way.

The third photo shows growth after 4 weeks - spring onions steams are ready to be used.

Step 7: Harvesting

After 4 weeks growth some of the steams were cut and added to mash potatoes. This made the potatoes more flavoursome.

Step 8: What Vegetables Grow Well in Planters?

The number one vegetable to grow in planters is Silver Beet, It's the 'Boarder Collie' of vegetables and delivers. I grew some from seeds and have been just breaking off a leaf from the base of each plant by twisting and tearing it when required. This way the leaves keep growing and you keep having a ready supply at hand. Goes well as a side to scrambled eggs in the morning.

Parsley also grows well from seed. I have planted some spring onions seeds and while they are growing well, just planting the cut off base as described above appears to be better.

I was keeping the planters watered using a series of 2-liter plastic bottles of filled water, until I purchased a 9-liter plastic watering can - far better than having to fill up multiple plastic bottles all the time.

A couple of days ago I purchased an Automatic Watering System for Potted Plants with a Programmable Timer, I am hopeful it will keep the plants watered while I am away for a couple of weeks on holiday. https://amzn.asia/d/2G0PiE2
