Master My Garden Podcast

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. Subscribe, share the episode with a gardening friend, and leave a review. What’s the one shaded spot you most want to transform?

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.

Thinking about a greenhouse but unsure where to start? We take you through a clear, practical roadmap for choosing a structure that won’t buckle in the first storm and will pay you back with tomatoes, peppers, and salads long after the summer fades. Drawing on listener questions from recent workshops and a lively grow-your-own webinar, we unpack siting, materials, and the small decisions that make a big difference to yield and ease of use.

We start with the real gains: longer seasons on both ends of the year, reliable warm conditions for tender crops in the Irish climate, and a daily rhythm that makes fresh herbs an arm’s-length habit. Then we get into the site plan. Keep it close to the kitchen for quick harvests. Prioritise overall sun capture rather than obsessing over a north–south ridge. If your garden is exposed, put shelter first and sun second; a greenhouse that stays put produces more than one that sails away. Clean glazing matters more than you think, and rainwater harvesting is best designed in from day one.

Next, we compare greenhouse types without brand hype. Glasshouses win on looks and heat retention, with options for toughened safety glass and long-term durability. Polytunnels deliver the most space per euro and can last many years when frames are strong and covers are tight, but they need proper ventilation. Modern polycarbonate houses—especially twin-wall and storm-ready builds—have proven themselves recently, offering warmth and resilience if assembled with quality fixings. Across all types, the rule holds: buy the best you can afford, secure every panel, and size up because you will fill it.

Inside, layout is simple and effective: ground beds on soil for better rooting and easier care, raised beds only if you’re on hardstanding or need extra height for access. Create airflow, plan clear paths, and leave room for a chair. We also share how to manage spring’s wild temperature swings—vent when sunny, protect before cold nights, and ease seedlings into change. By the end, you’ll know where to put your greenhouse, which build suits your site, and which features to lock in from the start.

Ready to sow with confidence instead of crossing your fingers? March brings longer days and real momentum, but cold, wet ground can still undo good plans. We break down exactly what to start now under cover, what needs heat, and what should wait a week or two, so you save seed, time, and energy while setting up a strong season.

We begin with the crops that make March feel productive fast: salads like spring onions, spinach, radish, and a range of lettuces that thrive in plug trays and tunnels. Then we map out the cool-season backbone of a kitchen garden with brassicas and alliums, from cabbage and cauliflower to onions, shallots, and leeks. Root crops get nuanced advice: early carrots under cover, beetroot for a head start, and a realistic plan for parsnips when soil finally dries. For heat lovers—tomatoes, peppers, and chillies—we explain why steady night temperatures and a basic propagator make the difference between sturdy transplants and setbacks.

Herbs bring flexibility, with parsley and coriander on a little-and-often schedule and practical reasons to buy thyme, sage, and rosemary as small plants. We also time peas and broad beans for tidy module-grown transplants that beat slugs and claggy beds. Flowers round out the plan: sweet peas, cosmos, marigolds, lobelia, nasturtiums, and sunflowers for cheerful summer displays, plus summer bulbs and tubers like dahlias and lilies to anchor borders with bold colour. Throughout, we keep one principle front and centre: sow by conditions, not by the month on the packet. Protect tender seedlings, harden off with care, and wait for the soil to say yes.

If this guide helps you plan your March, share it with a gardening friend, subscribe for monthly sowing plans, and leave a review to help others find the show. What will you start first under cover this week?
