FAQs About Seasonal Plant Care
1. Should I fertilize plants in winter?
No, most plants go dormant in winter, so fertilization should pause until spring.
2. When should I repot houseplants?
The best time is early spring, just before the growing season starts.
3. How often should I water plants in summer?
Outdoor plants may need daily watering, while indoor plants should be checked every 2–3 days.
4. Can I move indoor plants outdoors in summer?
Yes, but introduce them gradually to avoid sunburn. Start with partial shade before full sun.
5. Why do my plants lose leaves in fall and winter?
It’s often a natural dormancy process. Adjust watering and keep them away from drafts to minimize stress.
