About Mortgage Lifter Bean

Phaseolus vulgaris 'Dragon Tongue' · also called Dragon Tongue bean, Dutch yellow wax bean · edible

Dragon Tongue is a Dutch heirloom bush bean (Phaseolus vulgaris) with flat, creamy-yellow pods streaked purple, eaten young as a snap bean or dried as a shell bean. It is a compact, fast, productive bush needing full sun, warm soil and even moisture, and crops within about 60 days of sowing.

Mature size: 40-60 cm tall and roughly as wide; no staking needed.

Watch for — Halo blight / bacterial blight: Water-soaked spots with yellow halos spread in wet conditions; use clean seed, avoid wetting foliage and rotate beds.

How to tell mortgage lifter bean needs repotting

Repotting on a calendar is less reliable than reading the plant. For mortgage lifter bean, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot mortgage lifter bean on before it becomes hard root-bound.

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 mortgage lifter bean

Pot on seedlings as they grow; not a perennial repot. Mortgage Lifter Beanis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Compact, self-supporting bush bean reaching maturity quickly; bears flat pods in flushes that benefit from regular picking..

What size pot to step mortgage lifter bean up to

Pot mortgage lifter bean on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot mortgage lifter bean

Pot mortgage lifter bean on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting mortgage lifter bean

Pot on before it is root-bound. Check mortgage lifter bean regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh light, free-draining loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water mortgage lifter bean in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for mortgage lifter bean

Mortgage Lifter Bean wants light, free-draining loam. Moderately fertile, well-drained soil; pH 6.0-7.0. As a legume it fixes its own nitrogen, so avoid heavy nitrogen feeding. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting mortgage lifter bean — frequently asked questions

How often should you repot mortgage lifter bean?

Pot on seedlings as they grow; not a perennial repot for mortgage lifter bean. Mortgage Lifter Bean is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into light, free-draining loam so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does mortgage lifter bean need?

When is the best time of year to repot mortgage lifter bean?

Can you put mortgage lifter bean straight into a much bigger pot?

No. Even a fast-growing mortgage lifter bean should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise mortgage lifter bean after repotting?

Not immediately. Wait about 1 week after repotting mortgage lifter bean. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
