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.

Mature size: 5–7 m (16–23 ft) tall with support in favourable conditions

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.

How to tell tellmann's honeysuckle needs repotting

Repotting on a calendar is less reliable than reading the plant. For tellmann's honeysuckle, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for tellmann's honeysuckle) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot tellmann's honeysuckle

Only every 2–4 years, when genuinely crowded. Tellmann's honeysuckle is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Vigorous deciduous twining climber; stems twine around supports; benefits from training on wires or a sturdy trellis.

What size pot to step tellmann's honeysuckle up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Tellmann's honeysuckle positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping tellmann's honeysuckle into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

The best time of year to repot tellmann's honeysuckle

Early spring, just as new growth restarts, is the ideal window for tellmann's honeysuckle. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting tellmann's honeysuckle

Confirm it actually needs it. Slide tellmann's honeysuckle out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip tellmann's honeysuckle out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh fertile, humus-rich, moist but well-drained soil, ph 6.0–7.5, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water tellmann's honeysuckle again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for tellmann's honeysuckle

Tellmann's honeysuckle wants fertile, humus-rich, moist but well-drained soil, ph 6.0–7.5. Grows in any fertile, reasonably moist, well-drained soil. Enrich with organic matter at planting. Position the root zone in deep shade — at least 45–60 cm away from a wall base to avoid dry shadow zones. Mulch annually with leaf mould or composted bark. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting tellmann's honeysuckle — frequently asked questions

How often should you repot tellmann's honeysuckle?

Only every 2–4 years, when genuinely crowded for tellmann's honeysuckle. Only repot tellmann's honeysuckle every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using fertile, humus-rich, moist but well-drained soil, ph 6.0–7.5. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does tellmann's honeysuckle need?

When is the best time of year to repot tellmann's honeysuckle?

Does tellmann's honeysuckle like to be root-bound?

Yes — tellmann's honeysuckle genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise tellmann's honeysuckle after repotting?

Not immediately. Wait about 4 weeks after repotting tellmann's honeysuckle. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
