About Tellmann's honeysuckle
Lonicera x tellmanniana · also called Tellmann's honeysuckle, Redgold honeysuckle · flowering
A spectacular hybrid climbing honeysuckle (L. sempervirens x L. tragophylla) bearing large, coppery-orange to golden-yellow tubular flowers in generous clusters from late spring to midsummer. Unscented but extraordinarily showy; RHS Award of Garden Merit recipient. Deciduous and hardy to USDA zone 4, it performs best with sun on its canopy and cool shade at its roots.
Preferred mix: Fertile, humus-rich, moist but well-drained soil, pH 6.0–7.5
Watch for — Powdery mildew: The most common issue, especially in warm, dry summers or crowded positions. Water consistently, mulch deeply, and ensure good air circulation around stems. Apply sulphur-based fungicide at first sign. Mildew is worse where roots dry out.
Why tellmann's honeysuckle needs this mix
Tellmann's honeysuckle flowers hardest in a rich but free-draining loam — fed enough to fuel the display, open enough that the roots never waterlog.
- Flowering is expensive for tellmann's honeysuckle: producing buds, blooms and seed draws heavily on nutrients and steady moisture, so the soil has to keep delivering all season.
- A loam-based mix holds nutrients and water far more evenly than a light peat mix, which means a longer, more reliable flowering period.
- It still needs sharp drainage — most flowering plants resent cold, wet feet far more than they resent being a little lean.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons tellmann's honeysuckle struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A thin, hungry or sandy mix gives tellmann's honeysuckle weak growth and few, short-lived flowers — it simply runs out of fuel.
- A heavy, badly drained soil rots the roots or crown, often over a wet winter, and you lose the plant before it ever flowers again.
- Over-rich, high-nitrogen mixes can push lush leaf at the expense of flowers — balance, not excess, is the aim.
Either starving tellmann's honeysuckle in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.
pH — does it matter for tellmann's honeysuckle?
Most flowering plants, including tellmann's honeysuckle, do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A quality bagged compost works for tellmann's honeysuckle in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
Drainage and the pot
Free drainage protects the roots and especially the crown over winter — raised beds, grit in the planting hole and never a waterlogged spot. Containers must have a clear drainage hole.
For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for tellmann's honeysuckle covers the timing and technique step by step.
