Master My Garden Podcast

You can spend a fortune on compost, seed, and clever gear and still end up with tired raised beds and a mossy lawn if you get the basics wrong at the start. We’re answering two listener questions that keep popping up because they sound simple, but the wrong advice can cost you seasons of progress.

First up, raised beds in a polytunnel or greenhouse. We dig into the big mistake of putting ground cover fabric or plastic membranes under your growing media. I explain why that layer cuts your beds off from native soil life, why that matters for long term soil health, and what to do instead. We keep it practical: cardboard, quality compost, steady moisture, and keeping beds planted or mulched so the soil food web stays alive. If you’ve already lined beds with plastic, we talk through realistic options to reopen access and start rebuilding.

Then we switch to a problem nearly everyone sees after a long wet winter: moss in lawns. We break down the most effective lawn care approach for heavy moss, including scarifying, debris removal, top dressing, and reseeding or overseeding. We also compare slower bacterial treatments, the quick blackening effect of iron sulphate, and why raking is essential. Finally, we touch on how robot mowers can help reduce moss by encouraging thicker grass growth.

Want to grow your own cut flower garden ? Then this episode is for you.
 We’re joined by Fionnuala Fallon, Irish Times garden writer and a flower farmer growing on brilliant soil in County Laois, to unpack what it actually takes to produce beautiful, seasonal wedding flowers without leaning on synthetic chemicals.

We chat through the real foundations of sustainable flower farming: protecting soil health, keeping structure intact, and building fertility with local manures, straw mulches, and simple feeds like nettle tea. Fanula shares the practical decisions that helped her get beds established on a budget, including weed suppression and “little dig” cultivation when ground hasn’t been worked for decades. If you love cut flowers and want stronger stems with better vase life, the soil section alone is worth a rewind.

Then we get into propagation and seasonality for the Irish climate. You don’t need a polytunnel to raise great seedlings, but you do need light, frost protection, and reliable peat-free seed compost. We also talk about the tight harvesting window for local flowers, how late frosts can hit, and why many growers balance homegrown stems with carefully chosen imports. Along the way we share favourite plants for a home cut flower garden, including hardy shrubs and perennials that are often overlooked, plus practical dahlias advice for wet winters.

March can feel like four seasons in a week, and that’s exactly why an April seed sowing guide is so useful. We sit down with the reality of spring weather swings and turn them into a practical plan: what to sow now under cover, what to hold back until soils warm, and how to stay flexible so you don’t waste seed or stall your garden momentum.

We run through a packed “what to sow in April” list for the vegetable garden, starting with reliable salads like lettuce, spring onions, spinach, radish and rocket, then moving into brassicas, peas and beans, and the root crops that start to make sense as beds dry out. We also share timing notes for onions and leeks, the value of multi-sowing, and why fresh parsnip seed matters more than people realise. For warm-season crops like tomatoes, cucumbers, courgettes and squash, we talk about the late-but-still-possible window and the importance of steady warmth.

Seedlings don’t love extremes, and we unpack a common spring problem: huge temperature variance in a greenhouse or polytunnel that can leave young plants looking sorry for themselves. You’ll also hear a simple way to keep harvests coming with microgreens, even when outside is still stop-start.

On the ornamental side, April is where annual flowers really kick off, with options like cosmos, sunflowers, nasturtiums, cornflowers and nigella, plus a great case for growing dahlias from seed and planting bulbs and tubers for summer colour. 
Grow Your Own Herbs Workshop: 
We finish with a look at upcoming workshops, including a herb-focused day with Laura Darcy of Yarrow lane Herbs that connects growing with real-world uses like teas and home remedies.

Shade can be one of the most beautiful parts of a garden, but only if you stop treating it like a sunny border. We take a listener’s question and turn it into a clear, usable planting plan for dappled light and deeper shade, starting with the real foundation: soil. If you want shade plants to thrive, we explain how to recreate a woodland feel with humus rich ground using leaf mould and compost, and how that helps whether you’re dealing with dry shade or damp, heavy shade.

From there we share ten dependable choices you can actually build a bed around. On the perennial side we talk through astilbe for summer flower and foliage, hostas for bold leaves (with a honest warning about slugs), hellebores for winter and early spring colour and pollinator value, heuchera for vibrant foliage in low light (plus vine weevil watch-outs), and epimedium for early flowers when the garden still feels gloomy. Then we add shrubs for structure and year-round presence: acers that love shelter from wind, mahonia for winter yellow blooms, sarcococca for that unforgettable Christmas fragrance, viburnum for evergreen reliability, and skimmia for glossy colour in shade with a preference for slightly acidic soil.

We also name extra shade-friendly plants to widen your options, point you towards a previous shade specialist chat, and share news about an upcoming medicinal plant workshop, plus a teaser on AI and gardening content. If you’ve got a tricky dark corner, you’ll leave with a shortlist, a soil plan, and the confidence to apply “right plant, right place” properly.

A single tree can feel like a drop in the ocean, but stack that effort across hundreds of communities and you get something powerful: a greener Ireland built from the ground up. We’re marking National Tree Week by talking through what it is, why it exists, and how local groups can turn overlooked corners of land into long-term canopy with real environmental value.

We dig into the benefits that actually matter on the ground: carbon drawdown over time, better habitat for wildlife, and stronger biodiversity where native woodland has been lost. I also keep coming back to the one rule that saves years of hassle in gardens and public spaces alike: right tree right place. A great tree in the wrong spot becomes a problem; the same tree in the right spot becomes a legacy.

From alder and willow for wet ground to hawthorn, hazel, holly, rowan, crabapple, and the mighty oak, we run through native Irish trees and what they offer pollinators, birds, and the wider ecosystem. We also look at familiar non-native staples like sycamore and lime, especially their value for bees, and why size and site conditions matter more than hype.

To finish, we chat about the stubborn spring weather and the way big temperature swings in a polytunnel can throw off seed sowing and germination, plus a quick update on the next grow-your-own food workshop.
