Removing the tip removes the suppression, allowing buds at the leaf nodes below to break and grow. This apical dominance explains why cutting back a herb leads to bushier growth, not less.</p>https://rootandwindow.co.uk/blog/common-mistakes-when-growing-herbs-indoors-uk/Mon, 07 Sep 2026 23:53:21 +0000https://rootandwindow.co.uk/blog/common-mistakes-when-growing-herbs-indoors-uk/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>That yellow leaf on your basil isn&rsquo;t the problem—pouring more water on it is. Indoor herbs rarely die from the first mistake; they die from the wrong response to it. A yellow leaf met with excess watering becomes root rot; a leggy plant moved to a darker corner stretches further. This article breaks the cascade at each link, showing you exactly where to intervene.</p>https://rootandwindow.co.uk/blog/best-windowsill-position-herbs-light-requirements-uk/Mon, 07 Sep 2026 23:47:11 +0000https://rootandwindow.co.uk/blog/best-windowsill-position-herbs-light-requirements-uk/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>A south-facing windowsill in the UK receives up to 8 hours of direct sunlight on a summer day, dropping to 2-3 hours in winter. An east-facing window gets strong morning light, a west-facing one afternoon light. A north-facing window receives no direct sun year-round. This inventory dictates which herbs can survive where in your home.</p>https://rootandwindow.co.uk/blog/pot-supermarket-herbs-indoor-growing-uk/Mon, 07 Sep 2026 23:43:43 +0000https://rootandwindow.co.uk/blog/pot-supermarket-herbs-indoor-growing-uk/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Supermarket herb pots are grown for a short retail life, not sustained growth. They&rsquo;re sown densely to look full on the shelf, grown in peat-based compost that dries out unpredictably, and complete their production cycle in just a few weeks. When you bring one home, you&rsquo;re inheriting a system designed to fail unless you intervene at the root level.</p>https://rootandwindow.co.uk/blog/basil-growing-conditions/Mon, 07 Sep 2026 23:39:35 +0000https://rootandwindow.co.uk/blog/basil-growing-conditions/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>That lush pot of basil from the supermarket isn&rsquo;t a houseplant; it&rsquo;s a tropical summer annual. Every common windowsill failure—blackening stems, woody growth, tasteless leaves—stems from that mismatch. A UK winter provides neither the heat nor the sustained sun a basil plant evolved to expect. This guide explains the specific conditions that close that gap, moving it from a doomed seasonal purchase to a reliable kitchen crop.</p>https://rootandwindow.co.uk/blog/mint-plant-care/Mon, 07 Sep 2026 23:35:00 +0000https://rootandwindow.co.uk/blog/mint-plant-care/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Mint&rsquo;s aggressive reputation in the garden comes from its underground rhizome system—a network of horizontal runners that relentlessly colonise new soil. This same biological mechanism that makes it invasive outdoors is precisely why it struggles in a small container. The rhizomes, designed to spread through open ground, become trapped, circling back on themselves to create a dense root mass that starves the plant from below.</p>https://rootandwindow.co.uk/blog/herbs-grow-shade/Mon, 07 Sep 2026 23:29:47 +0000https://rootandwindow.co.uk/blog/herbs-grow-shade/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Yes, you can grow herbs in shade—mint, chives, chervil, parsley, coriander, and dill will all succeed. Basil, rosemary, thyme, and oregano will almost certainly fail. The distinction exists because the successful herbs evolved in damp, shaded woodland edges, while the failures need the intense sun of Mediterranean hillsides. This isn&rsquo;t about preference; it&rsquo;s about biology.</p>https://rootandwindow.co.uk/blog/growing-thyme-pots/Mon, 07 Sep 2026 23:21:39 +0000https://rootandwindow.co.uk/blog/growing-thyme-pots/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Thyme in pots tends to fail from generosity, not neglect. The typical mistake is giving it rich compost and attentive watering – the very things that kill it. To keep thyme alive, you need to adopt a regime that feels like under-care.</p>https://rootandwindow.co.uk/blog/often-water-rosemary-thyme/Mon, 07 Sep 2026 23:18:23 +0000https://rootandwindow.co.uk/blog/often-water-rosemary-thyme/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>The instruction on supermarket pots says water once a week. That advice rarely survives contact with a centrally heated UK flat. In winter, with the heating on and light levels low, you might find yourself watering rosemary and thyme only once every fortnight.</p>https://rootandwindow.co.uk/blog/often-water-basil-parsley/Mon, 07 Sep 2026 23:13:22 +0000https://rootandwindow.co.uk/blog/often-water-basil-parsley/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Basil soil should feel dry about 2.5 cm down before you water it. For parsley, wait until the top 1 cm of compost is dry. These two measurements—and the gap between them—explain most indoor herb deaths in UK kitchens. Watering both plants on the same schedule is the most common mistake, but the solution is simpler than you think.</p>https://rootandwindow.co.uk/blog/growing-herbs-indoors-uk-complete-windowsill-care-guide/Mon, 07 Sep 2026 23:09:59 +0000https://rootandwindow.co.uk/blog/growing-herbs-indoors-uk-complete-windowsill-care-guide/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Growing herbs indoors in the UK means managing every variable—light, soil, water, pot size, and the shifting British seasons—that determines whether your windowsill plants flourish or fail. This guide is structured to first explain why UK conditions are unique, then help you choose suitable herbs and a starting method, before detailing the setup and troubleshooting needed for long-term success.</p>https://rootandwindow.co.uk/blog/my-parsley-not-growing/Mon, 07 Sep 2026 23:05:46 +0000https://rootandwindow.co.uk/blog/my-parsley-not-growing/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Parsley seeds need soil temperatures consistently above 20°C to germinate properly. From October through April, many UK windowsills hover around 10-15°C—too cold for the seeds to start. You can check your own sill by placing a thermometer on it overnight or simply feeling how cold the pot feels to the touch.</p>https://rootandwindow.co.uk/blog/my-parsley-turning-yellow/Mon, 07 Sep 2026 23:00:20 +0000https://rootandwindow.co.uk/blog/my-parsley-turning-yellow/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>Parsley grows new stems from its centre, where a cluster of young leaves forms the plant&rsquo;s primary growing point. Cutting these central stems damages the production hub and can trigger yellowing as the plant struggles to recover. This botanical mechanism explains why harvesting technique matters more than watering frequency for keeping parsley green.</p>https://rootandwindow.co.uk/blog/my-thyme-dying/Mon, 07 Sep 2026 22:56:05 +0000https://rootandwindow.co.uk/blog/my-thyme-dying/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>From November to February, thyme in a UK pot enters a visible dormancy period. Stems turn woody, leaves may brown at the edges, and growth slows to almost nothing. These are normal winter cues, not necessarily signs of death. The real problem comes when you mistake this natural dormancy for a cry for help and reach for the watering can.</p>https://rootandwindow.co.uk/blog/my-coriander-flowering/Mon, 07 Sep 2026 22:50:40 +0000https://rootandwindow.co.uk/blog/my-coriander-flowering/<p><em>This page contains affiliate links.

Producing seed is its entire biological programme. The indoor grower&rsquo;s job isn&rsquo;t to stop it, but to delay the trigger. This article identifies what pulls that trigger inside your flat.</p>https://rootandwindow.co.uk/blog/my-coriander-not-growing/Mon, 07 Sep 2026 22:46:11 +0000https://rootandwindow.co.uk/blog/my-coriander-not-growing/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>The hot, sunny windowsill that suits basil is exactly what pushes coriander to stall and bolt. Coriander wants bright but cool light, so the first fix is position, not feeding or water. Yet even in a perfect spot, you might still face tall, flowering plants with sparse, bitter leaves.</p>https://rootandwindow.co.uk/blog/my-mint-plant-so-leggy/Mon, 07 Sep 2026 22:40:26 +0000https://rootandwindow.co.uk/blog/my-mint-plant-so-leggy/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>A leggy mint plant is the most fixable windowsill problem because mint regrows from every node. A hard cut plus corrected light restores compact growth within weeks. This article gives both halves of that fix.</p>https://rootandwindow.co.uk/blog/my-mint-plant-dying/Mon, 07 Sep 2026 22:35:07 +0000https://rootandwindow.co.uk/blog/my-mint-plant-dying/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>The minimum pot size for a mint plant to sustain itself indoors is roughly 20 cm in diameter and 15 cm deep. The small plastic pot a supermarket mint arrives in is typically half that size. That single dimensional fact is why so many indoor mint plants fail.</p>https://rootandwindow.co.uk/blog/my-rosemary-dying/Mon, 07 Sep 2026 22:29:03 +0000https://rootandwindow.co.uk/blog/my-rosemary-dying/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>That rosemary on your windowsill shows all the classic signs of drought—browning tips and dropping needles. But the soil beneath feels cold and damp. This is the cruel trick rosemary plays: it displays thirst symptoms when its roots are actually drowning. The instinct to water it more or give it extra sun only speeds up the decline. The key is a simple soil test to tell the difference, then a permanent fix that changes the environment, not just your watering habits.</p>https://rootandwindow.co.uk/blog/my-basil-turning-yellow/Mon, 07 Sep 2026 22:23:57 +0000https://rootandwindow.co.uk/blog/my-basil-turning-yellow/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>When the lower leaves on your basil turn yellow, the standard advice to water more actively worsens the problem. Yellowing basil in a UK home is almost always a nitrogen-depletion issue, not a watering problem. The plant is pulling nutrients from its older leaves to fuel new growth, and adding water won&rsquo;t replace what&rsquo;s missing.</p>https://rootandwindow.co.uk/blog/my-basil-plant-dying/Mon, 07 Sep 2026 22:19:08 +0000https://rootandwindow.co.uk/blog/my-basil-plant-dying/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>The black stems on your basil are the final chapter. The problem began days, maybe weeks, earlier, hidden in the roots. You&rsquo;re seeing the end of a story that started when the plant left the greenhouse.</p>https://rootandwindow.co.uk/blog/indoor-herb-rescue-uk-diagnose-save-dying-windowsill-herbs/Mon, 07 Sep 2026 22:14:54 +0000https://rootandwindow.co.uk/blog/indoor-herb-rescue-uk-diagnose-save-dying-windowsill-herbs/<p><em>This page contains affiliate links. As an Amazon Associate we earn from qualifying purchases — this does not affect the price you pay.</em></p> <p>A failing windowsill herb almost always suffers from one of three root causes: insufficient light, incorrect watering, or an unsuitable herb variety. Identifying which problem you&rsquo;re facing is the single most important step—it dictates the entire rescue plan. Misdiagnosis, like treating a light-starved basil as if it&rsquo;s thirsty, accelerates the decline. This guide helps you pinpoint the real issue using a simple triage framework built for UK homes.</p>
