Should I withhold fertilizer to keep a bonsai small?

No. Bonsai size is managed through appropriate training, pruning, and root restriction, while the tree still needs nutrients for healthy growth. Its small container holds a limited supply, so follow a suitable low-dose feeding program during active growth. Avoid excessive feeding as well. Identify the tree species first because the timing of growth and pruning matters more than treating miniature size as a reason to starve it.

Why won't my bonsai rootball lift out of its pot for repotting?

Check whether securing wire passes through the pot and holds the tree in place. Release that attachment before pulling harder, then proceed with species-appropriate repotting and root work. Bonsai are sometimes anchored for stability, so resistance does not necessarily mean roots have glued themselves to the container. Inspect the underside and surface carefully to avoid tearing roots or damaging the trunk through unnecessary force.

How can I encourage flowers lower down on a climbing rose?

Train suitable flexible main canes as horizontally as practical along their supports, or gently around a pillar, to encourage flowering side shoots along their length. Tie them securely with room for growth and avoid forcing stiff old canes into sharp bends. Keep healthy framework stems while using pruning guidance for that rose type. A tall vertical stem often concentrates its display nearer the top.

What should I check before separating a shrub's root sucker to make a new plant?

For a suitable non-grafted shrub, expose the sucker carefully and make sure the piece you detach includes fibrous roots. A long shoot with little root cannot support itself well after separation. Spring is a useful time as growth resumes. Replant promptly and give careful watering through its first season, because the new root system is still small compared with the shoot it must supply.
