About Skyrocket Juniper
Juniperus scopulorum 'Skyrocket' · also called Skyrocket Juniper, Rocky Mountain Juniper · flowering
Skyrocket Juniper is a strikingly narrow, columnar evergreen reaching 4-6 m tall yet only 60-90 cm wide, with fine silver-blue foliage. Its pencil-thin, upright form makes a bold vertical accent, screen or formal pairing. A Rocky Mountain juniper selection, it demands full sun and sharply drained soil and is notably drought- and cold-tolerant.
Plant type: flowering
The reasons skyrocket juniper isn't blooming
Almost every non-blooming skyrocket juniper traces back to one of these, roughly in order of how common they are:
- Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
- Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
- The plant has not been deadheaded, so it stops flowering once it sets seed.
- Irregular watering — drought or waterlogging at the budding stage makes buds abort.
- It is still too young or was checked by a transplant and is rebuilding before flowering.
Feeding skyrocket juniper a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.
The fix — how to get skyrocket juniper to flower
- Maximise sun. Give skyrocket juniper the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
- Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
- Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
- Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.
Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for skyrocket juniper and get the feeding right with the skyrocket juniper fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.
Bloom season and what to expect
Skyrocket Juniper flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.
Post-bloom care so it flowers again
Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
For everything else this plant needs day to day, see the full skyrocket juniper care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.
Skyrocket Juniper blooming — frequently asked questions
Why won't my skyrocket juniper flower?
