This week’s episode has been a satisfying mix of big winter jobs finally completed, steady progress in both the kitchen garden and the allotment, and the start of the busy seed‑sowing season. Here’s a written look at everything covered in Episode 648.

Kitchen Garden Update

The biggest achievement this week was removing the large elm tree that had taken root beside the greenhouse. What looked manageable from the ground turned out to be around five metres tall, meaning a scaffold tower was needed to safely take it down. As you said in the episode, climbing up reminded you that heights still aren’t your favourite place to be, but the job needed doing and it’s now complete.

With the stump cut low, a Dalek compost bin has been placed over the top. This is a method you’ve used many times before. By excluding light and keeping the area damp with added compostable material, the stump slowly rots away over a year or two. It’s simple, inexpensive and avoids the need for heavy machinery.

The thinner branches have already been shredded for woodchip, which will be used around the garden and in the chicken coop. The thicker pieces will dry out and become winter fuel later in the year. It’s another step toward making the garden as self‑sufficient as possible.

Elsewhere in the garden, weeds are being cleared and the chillies and peppers moved to the potting shed last week are looking strong and dark green. Seed potatoes also arrived this week. Eight varieties in total, now chitting in the potting shed and greenhouse. Chitting isn’t essential, but as you explained, if potatoes are going to sprout anyway, it makes sense to control the process and encourage sturdy, healthy shoots.

Down on the Allotment

A mostly dry week had raised hopes for good soil conditions, but Friday’s rain left the ground claggy in places. Beds that haven’t had much organic matter added over the years were noticeably harder to hoe, while beds enriched with compost were far easier to work. It’s a clear reminder of how much difference organic matter makes to soil structure.

The strimmer came in handy for cutting weeds where hoeing wasn’t possible. After that, homemade compost was spread on the poorer beds. Each bed takes around five wheelbarrow loads, and one compost bin filled only three beds, showing just how much compost a productive allotment needs. The long‑term goal remains the same: to produce enough compost on site to avoid buying any in.

A new dwarf variety of Jerusalem artichoke called Small Wonder has also been planted. These grow to around 80cm tall, far more manageable than the towering varieties grown in previous years. Planting them in a large pot should help contain the tubers and make harvesting easier.

Recipe of the Week

Chef Scott returned with a seasonal dish: a warm salad of chargrilled spring vegetables with feta, mint and chilli. It features purple sprouting broccoli, spring cabbage, asparagus and peas, brought together with lemon zest, chilli, mint sauce and crumbled feta. A simple, fresh recipe that pairs beautifully with spring lamb chops. The full method is available on the Veg Grower Podcast website.

Main Topic: Tips for Successful Seed Germination

With March underway, seed sowing is now in full swing. Over the years you’ve developed a reliable routine for achieving strong germination, and this week’s episode shared those key principles.

The first is to use seed that is in date. Older seed can still germinate, but fresh seed gives the highest success rate. The second is to read the packet. Every seed has its own requirements, whether that’s light, darkness, warmth, soaking or chilling. The packet contains all the information needed to give each seed the right start.

A good quality seed compost is essential. A fine, free‑draining mix with added perlite and vermiculite creates the ideal balance of moisture and air. Checking seeds regularly is important, but patience is equally vital. Some seeds germinate quickly, others take their time.

Plug plant trays have become your preferred method for most seeds. One seed per cell saves compost, avoids pricking out and encourages strong root systems. Root crops remain the exception, as they prefer to be sown directly where they will grow.

Light becomes crucial once seeds germinate. A bright windowsill, greenhouse or grow lights prevent seedlings from becoming leggy. Watering from the bottom helps avoid disturbing seeds and reduces the risk of damping off. Gentle airflow strengthens seedlings and discourages fungal problems. Heat mats can be very helpful, but only gentle warmth is needed, and seedlings should be removed from the heat once they sprout.

These simple steps form a reliable routine that makes seed germination far more predictable and rewarding.
