As this is the first time I have tried planting in air-pruning plant pots, I’ve been watching my Sweet Peas very closely over the past seven weeks to see how they get along in my recycled milk carton plant pots with their cosy little made-to-measure fabric grow bags. I must say, I am quietly pleased with their progress.
I sowed the Sweet Pea seeds in mid-April – two per pot – and I was delighted to see the first seedlings germinate just five days later. Gradually over the next few days each of the seeds prodded its little green shoot through the compost.
After two weeks my Sweet Pea seedlings were all growing on well. I wanted to give the seedlings time to grow large enough to enable me to thread them onto the jute and willow garden screens I was creating as plant supports. So, for a little longer the seedlings resided on a specially-created plant shelf in an east-facing window – giving them plenty of light without too much strong sun.
In mid-May, a month after sowing, my growing Sweet Pea plants were ready for their outdoor adventure. I chose this particular time as we were enjoying a little burst of early Summer, so I knew the plants would be fine outdoors. I attached the air-pruning plant pots to the jute and willow garden screen – I’d designed the plant pots with this in mind. Now that the Sweet Pea plants were safely outdoors I gave them a good watering and added some of my ‘magic growing potion’ to give them a good start.
Over the last few weeks I’ve been watching over my little Sweet Pea plants. I spotted a suspicious-looking snail on a plant pot one morning so transported it to another location, far-removed from my Sweet Peas! I’ve also been regularly pinching out the side shoots that grow quite prolifically on Sweet Peas. Side shoots will be wonderful later when the plants have fully grown and are ready to flower, but for now they are taking up energy that I’d prefer to see grow into the main plant stem.
My only exception to this lately, is with one of the plants that seems to have acquired its own sneaky slimy friend! As various parts of that plant have been eaten already, I’ve decided to let nature take its course and see whether any of the evidently-too-tasty shoots actually survive!
Today, I also took a closer look at how the roots are progressing in their air-pruning plant pots. There is some evidence of root growth inside the remaining plastic parts of the milk carton, though none to see where the grow bag is exposed to the air through the large holes. Using air-pruning plant pots is a new experiment for me, so I am observing how plant growth is impacted with this method of growing.
The Sweet Pea plants are certainly growing on well – I think they seem to grow perceptibly each day. This morning, as I checked the plants growing on the willow screen on my backyard gate, I see they have now reached about half way up. The plants measured 24 inches high (that’s about 60 cms)!
There’s more heavy rain forecast for tomorrow. After that I shall feed the Sweet Peas some more ‘magic potion’. I shall make this year’s batch of new ‘potion’ soon and then I’ll share the secret 🙂
