  2. Fertilization: Potted flowers may require supplemental nutrients to thrive. Use a balanced water-soluble fertilizer, such as a 10-10-10 or 14-14-14 formula, once every two weeks during the growing season. Dilute the fertilizer according to the package instructions and apply it directly to the soil. Avoid applying fertilizer to dry soil, as it can cause burns to the roots.

  3. Deadheading: Removing spent flowers, a process known as deadheading, encourages continuous blooming and keeps the plant looking tidy. Pinch off the faded flowers at their base, just above a set of healthy leaves or nodes. This will redirect the plant’s energy towards producing new flowers rather than setting seeds.

  4. Pruning: Regular pruning promotes bushier growth and enhances the overall shape of the plant. Trim back leggy stems and remove any dead or damaged foliage. Use clean and sharp pruning shears to make clean cuts just above a pair of healthy leaves or nodes.

  5. Support: Some flowers may require support to prevent them from toppling over. Place stakes or trellises in the pot, if necessary, to provide support for climbing or heavy-flowering varieties. Tie the stems to the support using garden twine or soft plant ties, being careful not to damage the stems.

  6. Pest and disease control: Regularly inspect your potted flowers for signs of pests or disease. Common pests include aphids, mealybugs, and spider mites. Treat any infestations immediately by either washing off the pests with a strong spray of water or using an organic insecticide.

  7. Protection from extreme weather: Potted plants are more vulnerable to extreme temperatures, especially freezing conditions. Bring the pots indoors or to a sheltered area during frost or extreme heat to protect them from damage.
