Here are 7 shorter, easy-to-understand ways to say that sentence. Each one is 3–5 words shorter and still means the buds are getting ready to open:
- Buds swell, getting ready to show their pretty flowers and sticky new leaves.
- The buds swell to show off pretty flowers and sticky new leaves.
- Tiny buds swell up, about to show their pretty flowers and sticky leaves.
- Buds puff up getting set to reveal pretty flowers and sticky new leaves.
- The buds swell, soon showing pretty flowers and sticky new leaves.
- Buds swell, preparing to reveal pretty flowers and their sticky new leaves.
- Little buds swell up, ready to show pretty flowers and sticky new leaves.
All of these say the same thing: the buds are growing bigger and will open into flowers soon.
