Laburnum alpinum 'Pendulum'
- Position: full sun
- Soil: well-drained soil
- Rate of growth: fast-growing
- Flowering period: May to June
- Hardiness: fully hardy
Forming a small, spreading tree with weeping branches that cascade from an upright stem (the weeping top has been grafted onto the 130cm-ish tall stem), this is perfect for smaller gardens or large patio pots. In late spring and early summer slender racemes of brilliant, golden-yellow flowers seem to drip from the branches creating a luminous display. An excellent specimen plant, that is best appreciated when not overcrowded.
- Garden care: When planting, incoporate lots of well-rotted manure or garden compost into the planting hole and stake firmly. Laburnums dont need much pruning, but you may want to remove any diseased or crossing branches. It is essential that any pruning work is carried out between late summer to mid winter as the sap will 'bleed' heavily at other times.
- CAUTION toxic if eaten

Greetings Crocus, I need advise about my Laburnum, please. 12 years ago I purchased a Laburnum and was reassures by a Garden Centre that it would only grow to 2-3 metres It is much taller than that now, definitely 8 metres! Consequently it is blocking out the light from the downstairs rooms. Help! It is quite stunning when in bloom, as you can imagine. The Garden Centres have conflicting advise about what I should do. I would really like to know if I can prune it back now by about 3 metres as we are in October. Do you think I would stimulate rapid growth as a result of this action? I would appreciate your valued reply, Thank you ElizabethAsked on 16/10/2009 by E M MAJOR
A:Hello Elizabeth, It is difficult to advise on how the tree will respond without knowing which type of Laburnum you have. Some are vigorous, so even if you do cut it back it is likely to put on lots of new growth next spring, so if it is too big for the allocated spot, then you should really remove it and plant something better suited. If however you would like to give it a go, then the best time to prune is from late summer to before mid winter, but most rarely cope well with drastic pruning. I hope this helps.

A:Thanks very much Helen. I will give it a go, but I fear my laburnum is the vigorous type. We will see what happens Many thanks ElizabethAnswered on 19/10/2009 by E M MAJOR
October sees the start of the dormant season which is the best time to prune lots of deciduous garden trees. You can prune newly planted trees to remove any damaged growth and help balance the shape of the canopy as well as maintain a dominant main leaderRead full article
