Why does your Picea spruce grow as a candelabra?
Picea spruces have a mind of their own. While many conifers dutifully maintain a single central stem, a Picea can suddenly develop three, four, or five tops. This phenomenon is called "candelabra formation" - a tree that looks like a candelabra with multiple candles at the top. This often happens due to damage to the main stem (frost damage, breakage, disease) or because the tree naturally tends to form multiple leaders.
A Picea candelabra is not only unsightly. It also weakens the tree. With five tops, all the roots divide their nutrients across all those branches, resulting in weak growth. The tree becomes wide and uncontrolled. Eventually one of those tops breaks in the wind and you have permanent deformation.
The solution is early intervention: you redirect the tree back to a single leader before the candelabra problem becomes established.
How do you recognize a candelabra spruce?
A healthy Picea spruce has one clear top - the central leader shoot. If you examine your tree in March or April and see two, three, or more equally strong tops at the same height, you have a candelabra.
This usually happens because:
- The main stem broke last year (snow load, wind, frost damage)
- The top died off (disease, frost burn, fungus)
- The tree naturally forms multiple leaders (some cultivars)
Good news: you can fix it. Not difficult, but precise.
Step 1: Choose the strongest top
In March, look at your Picea and determine which of the tops is the strongest. Look at:
- Growth: Which top grows most upright and vigorously?
- Position: Which stands most centrally?
- Health: No brown needles, no damage, no disease?
That top becomes your new central leader.
Practice: If top 1 is left and top 2 is right, choose the straight one. If all three are equally strong, choose the one that grows most upright.
Step 2: Remove all other tops
This is the drastic part. The remaining tops - all of them - you cut away completely. Not cut back, not replace: completely remove.
Grab your pruning saw or strong pruning shears. Cut close to the base of each unwanted top. Leave no stump. This hurts physically - you are removing actual branches - but it works.
Why remove all? Because the tree will otherwise keep dividing its energy across all tops. A single, strong leader only wins if all competitors are gone.
Step 3: Care for the wounds
After pruning, you now have a tree with three, four, or five large open cut surfaces. This looks serious. Good news: Piecas heal wound wounds quickly and you do not need to seal the cuts with tar or silver.
Let them heal naturally. The tree forms wound tissue itself and closes the wounds. This takes several months.
In the first four weeks after pruning: care well for your tree. Water during dry periods. The tree uses lots of energy to heal.
Step 4: Guide the new leader
The tree now puts all its energy into the remaining central top. Excellent. That happens fast: within six weeks you see 20-30 cm of new growth on that leader.
Let that leader grow. Do not cut it back (unless damaged). Over the next three seasons you watch to make sure the candelabra problem does not return. Check each spring that the top is still central and undamaged.
After two, three seasons you will see the tree has recovered. The removed tops form only small scar marks. The tree grows again in its natural pyramid shape.
Small variety variations
Picea abies (Norway Spruce): Grows strongly upright. Candelabra rarely happens; usually damage-related. Prune carefully, the tree recovers fast.
Picea pungens (Blue Spruce): More naturally prone to multiple tops. Cut with a strong hand - this cultivar tolerates more aggressive pruning.
Picea omorika (Serbian Spruce): Very upright and columnar. Rarely candelabra. No worries.
Picea orientalis (Oriental Spruce): Fine needles, elegant. Can suffer from frost burn of the top. Prune carefully but decisively.
Frequently asked questions
How long does it take for the tree to look normal again?
Six months to a year. After pruning in March, you see the wounds overgrow quickly (May-June). By October the tree begins silhouette recovery. By next spring, the shape looks much better already.
Can I do this in summer or autumn?
Not ideal. March-April is really the best time. The tree is still dormant, wounds heal fast before growth, and you see results immediately. Summer pruning of heavy cuts is risky - the tree stresses and recovers more slowly.
I am afraid I will kill the tree by pruning. Is that risk real?
No. You only remove the extra tops - the tree still has a healthy central leader and branch structure. Piecas are tough and tolerate heavy pruning. You cannot prune so hard you kill the tree (unless you cut everything to the ground).
What if all tops are roughly equally strong?
Choose the one that grows most upright and stands most centrally. Not perfect? Does not matter. Cut the rest away. Within a few months the chosen leader grows out dominantly and dominates the tree.
Step-by-step
Step 1: Check your tree in March
Count all tops. Do you have more than one? Then you have a candelabra or multiple-top problem.
Step 2: Choose the strongest top
Select the top that is strongest, most upright, and healthiest. Mark it (for example with a string ribbon).
Step 3: Remove all other tops
Cut close to the base, no stump left. Pruning saw for thicker branches, strong shears for thinner.
Step 4: Let the tree heal
No tar or sealant needed. Provide water in dry weeks.
Step 5: Guide the leader over the next seasons
Check yearly that the leader stays central and healthy. Only cut if needed (damaged).
Frequently asked questions
What if the damaged top regrows?
Sometimes it happens. Some Piecas do not give up. Do not wait: cut it back as soon as you see it regrowing. Early intervention works better than waiting.
Can I still save a candelabra spruce with three tops?
Yes, certainly. It does not matter if you remove one, two, or five extra tops. Same procedure. Choose one, remove the rest.
The tree looks very damaged after pruning - is this normal?
Yes. Right after pruning, a tree certainly looks damaged - large scars at the top. This is completely normal and temporary. Over six weeks you see new growth that hides the scar.
