Fertilizing Garden Plants: When and How?
Why Fertilize?
Fertilizing helps garden plants get the nutrients they need for steady growth and flowering. Over time, soil nutrients can become depleted, especially in intensively planted or older gardens. Fertilizing can support plants during their main growing season, but not every plant or soil needs the same amount.
When to Fertilize: General Guidelines
- Spring: Most garden plants benefit from a light application of fertilizer in early spring, just as new growth begins.
- Summer: Some plants may need a second, lighter feeding in early summer, especially if they are heavy feeders or growing in poor soil.
- Autumn and Winter: Avoid fertilizing late in the season, as this can encourage soft growth that is vulnerable to frost.
- Always check the specific needs of your plant type and the condition of your soil. Over-fertilizing can do more harm than good.
Common Mistakes When Fertilizing
- Too much fertilizer: This can cause leaf burn, weak growth, or even root damage. Always follow recommended amounts and avoid doubling up.
- Fertilizing dry soil: Water the soil lightly before applying fertilizer to prevent root burn.
- Ignoring soil quality: If your soil is already rich, extra fertilizer may not be needed. Consider a soil test if you are unsure.
- Fertilizing at the wrong time: Late-season fertilizing can make plants more sensitive to frost.
