Whether or not that old packet of seeds will germinate is a question that often arises in gardening. But when the seeds in question have taken a trip to the International Space Station (ISS), the answer gets a bit more complicated. In 2015, a million rocket (AKA arugula) seeds blasted off to spend six months in space. When they returned to Earth in 2016 they faced an even larger challenge – they were to be sown by a horde of little fingers as the RHS Rocket Science experiment turned school children into space gardeners!
Announced at the RHS Chelsea Flower Show in 2015, Rocket Science was part of Tim Peake’s Principia mission to the ISS. For 35 days children nurtured and monitored two sets of rocket seedlings. One had been to space, and the other had stayed on Earth. Would they be able to tell the difference? The RHS collected and analysed the results, and published their Rocket Science: Our Voyage of Discovery report in November 2016. Their key finding was that there was a small difference, with the space seeds being slightly slower to germinate.
Scientists at Royal Holloway took over and carried out experiments in controlled conditions to find out why there might be a difference in germination time. They confirmed that the space seeds are slower to germinate because they had been aged (damaged) by their trip into space. Once the dry seeds are watered they can repair the damage, but doing so leads to a slight delay in germination. Once the seeds have germinated, they can grow as normal.

The Insulin Plant (Costus igneus), also known as ‘Spiral Ginger’ or ‘Fiery Costus,’ has garnered significant attention for its potential health benefits, particularly in managing blood sugar levels. In this article, we delve into the scientific research surrounding Insulin Plant Benefits, its active compounds, and how it can potentially support individuals with diabetes and beyond.
The existence of Blue Dragon Fruit has sparked curiosity and debate among horticulturists, fruit enthusiasts, and the general public. However, the question remains: Is it real, or is it merely a myth? Let’s find out!
The list of to-dos when it comes to selling your house might already seem daunting, but there’s one place where sellers should pay particular attention if they want to grab the attention of prospective buyers—and it starts with the yard. “When it comes to selling a home, first impressions matter,” says Realtor.com Executive News Editor Clare Trapasso. “The front yard is generally the first thing that prospective buyers see when visiting a home, so sellers should make sure that it oozes curb appeal.” That means a freshly cut lawn with trimmed hedges and weeded flower beds. Dead plants and spent blooms should be removed so all that’s left is a neat and welcoming home with a yard that doesn’t scream money pit.
Tile countertops: love them or leave them in the past? While some designers like New York City-based Emma Beryl think they bring «the '70s and '80s back into the kitchen,» others believe they should stay in the time capsule.
The first draft of my essay is done, and although I will revisit it in due course before the deadline, I thought I would take a few minutes to write a blog post that I have been pondering for some time now.
An ethnobotany superhero by night, my mild-mannered daytime alter ego is a science writer for the Science and Technology Facilities Council (STFC), one of the UK’s research councils. It’s not often that those two worlds collide, although during the early summer the campus I work on is dotted with the blooms of hardy orchids.
On Thursday I pottered out into the garden and planted some tea bags. This isn’t because I have some loony idea that they’ll grow into tea plants (you were wondering that, weren’t you?) – it’s all in the name of soil science.
Earlier this year, my father-in-law (FIL) visited while Ryan and I were finishing up putting the new metal-framed raised beds in our garden. He said, rather wistfully, that he missed having a vegetable garden. Although he and my mother-in-law (MIL) have quite a large garden, it’s all given over to ornamentals as my MIL is a highly skilled florist. (She did the flowers for our wedding.)
