Master My Garden Podcast

Planting vegetables every year is satisfying, but it can also feel like starting from scratch each spring. We go deep on perennial vegetables, the crops you establish once and then harvest for years, and why they’re such a smart move if you want a more resilient, lower-effort kitchen garden without giving up fresh homegrown food. I also share where my own experience is solid and where I’m still learning, so you can decide what’s genuinely worth your space. 

We weigh the real pros and cons: less annual sowing, earlier picking windows, and minimal soil disturbance for permaculture and food forest style gardens, balanced against the downsides of permanent planting, bulky growth, and the fact that some perennial veg simply tastes different to the annual versions. Patience matters too, especially with asparagus and rhubarb, where the best harvests come after a few seasons of establishment. 

From there, we work through a practical crop list including globe artichoke, Jerusalem artichoke, perennial kale varieties like Taunton Dean and Daubenton, nine-star broccoli, Egyptian walking onions, Welsh onions, wild garlic, horseradish, sorrel, sea kale, and even ways to get a “perennial effect” from crops like garlic or by changing how you harvest cabbage. I also mention Irish options for sourcing plants and why creating a dedicated perennial veg bed can keep everything manageable. 

If you enjoy gardening tips, perennial veg ideas, and realistic advice for Irish and UK-style growing conditions, subscribe, share the episode with a gardening friend, and leave a review. Which perennial vegetable are you most tempted to try first?

Hand watering a greenhouse during a heatwave can turn into a daily scramble: alarms set for dawn, hoses dragged in unbearable temperatures, and still you watch water vanish into thin air through evaporation. We’ve both seen how quickly a polytunnel can dry out, how fast IBCs and water butts can empty, and how risky it feels to leave watering to someone who isn’t a gardener. So we get practical about greenhouse irrigation and how to set it up properly while the tunnel is relatively clear.

We talk through the main irrigation options and what they mean for plant health: why overhead sprinklers often create too much humidity for tomatoes and cucumbers, and why drip irrigation is usually the smarter choice. Porous pipe, layflat hose, dripper pipe and individual drippers all deliver water gently at the root zone, keeping leaves dry and reducing disease pressure. We also cover the real-world details people trip over, like pressure limits, maximum run lengths, and why you should always build your system in zones with shut-off taps so you can control each line.

From there, we move into the backbone of any reliable greenhouse watering system: rainwater harvesting and storage, proper filtration to prevent blocked drippers, and choosing a timer that matches your setup. We share a straightforward order of operations (water source, filter, timer, feed line, irrigation lines), plus a checklist for testing flow from the first metre to the last. Finally, we touch on greenhouse shading, mulching, and the mindset shift that matters most: automation helps, but you still have to observe and stay vigilant.

The quickest way to waste money on a hedge is to choose with your eyes first and your site second. With bare-root season around the corner, we walk you through a simple decision process that stops costly mistakes and helps you pick hedge plants that actually suit your garden, your soil and the amount of maintenance you can commit to over the years. 

We start with the big questions: what do you need the hedge to do, do you want privacy or shelter, are you trying to stock-proof a boundary, or are you building a wildlife-friendly habitat? From there we look at real-world garden conditions that make or break a hedge, like waterlogged patches along an otherwise dry run, coastal wind, exposure and frost. We also clear up the evergreen versus deciduous choice, including why beech hedging behaves like an “almost evergreen” option most of the year. 

Then we get practical with a wide range of popular choices. We talk through evergreen hedges such as yew, holly, privet, box, lonicera nitida, escallonia, griselinia and laurel, including the key caveats around disease, cold damage and invasive potential depending on variety and management. On the deciduous side we cover beech, hornbeam for wetter ground, and native mixed hedging with hawthorn, blackthorn and hazel for better biodiversity, seasonal interest and a more natural look. Finally, we underline the make-or-break period after planting: keeping the base weed-free, protecting moisture during dry spells, and clipping early to avoid that dreaded gappy bottom. 

If you want a hedge that looks good, works hard and stays manageable for decades, hit play, then subscribe, share the podcast with a fellow gardener, and leave a review so more people can find it. What job does your next hedge need to do?

Timber raised beds rot. Cheap metal ones can rust, bow, and end up in the skip just as you’re getting the hang of growing. So what does a raised bed look like when it’s designed as a product for life? I’m joined by Brian O’Hara from East Cork, who built the Mia Grow Bed, an Irish-made aluminium raised garden bed with a 30-year warranty and a design that goes together in minutes. 

We talk about the real reason so many of us start a kitchen garden when kids arrive: you want better food, less waste, and a way to show children where meals actually come from. Brian shares his first season growing kale, herbs, cherry tomatoes, beetroot, strawberries and more, plus the small moments that make it addictive, like a three-year-old checking the bed every day and claiming nearly every strawberry. We also dig into choosing crops that give quick returns, especially when space and time are tight. 

Then we get practical and a bit nerdy: aluminium versus timber and galvanised steel, how rigid profiles stop beds bulging, what a wood grain finish really is, and why durability is a sustainability decision. We also cover modular raised beds, extension packs, and why manufacturing in Cork matters for quality and supply chain. If you care about grow your own, sustainable gardening, and smart garden design, you’ll take plenty from this one.

October gardening is a strange mix of momentum and endings: the weather can still feel warm, growth can still be strong, yet the shortening days quietly shut the door on many sowings. We talk through a clear, realistic October seed sowing guide that focuses on what still delivers value, especially if you want winter salads and a head start on spring.

We run through the best autumn and overwintering crops to sow now, including winter spring onions, mustard leaves, mizuna, rocket, hardy spinach, late radish, and useful herbs like coriander, dill, chervil, and parsley. We also cover the winter leaf staples that thrive when light levels drop, plus the option of broad beans later in the month for an early crop next year. Alongside seeds, we dig into planting jobs that matter in October: garlic and winter onion sets, and why splitting your planting between polytunnel and outdoor beds can give you staggered harvests and a more resilient kitchen garden.

Beyond sowing, we get practical about seasonal maintenance. We share tips for ripening tomatoes as sweetness fades with lower light, preparing and mulching empty beds, using green manures, and keeping polytunnel soil life alive with sensible watering. With autumn winds on the rise, we also talk polytunnel and greenhouse checks and quick repairs that prevent small tears becoming expensive problems.
