Feeding your plants at the right time can make a big difference to their growth, flowering, and overall health. But how do you know when your plants actually need feeding? Here are some common signs to look out for, and a few tips on what to do next.
1. Yellowing Leaves
If your plant's leaves are turning pale or yellow, especially older leaves near the base, it may be lacking nutrients—particularly nitrogen. Nitrogen is essential for leafy growth, and a lack of it is one of the most common signs a feed is needed.
2. Slow or Stunted Growth
If your plants seem to be growing more slowly than usual, or if they're smaller and weaker than expected, poor nutrition could be the cause. This is often seen in container plants, where nutrients can run out more quickly.
3. Fewer Flowers or Fruits
If your flowering plants are producing fewer blooms, or if fruits and vegetables are failing to develop properly, it could be a sign of a potassium deficiency. A balanced fertiliser or tomato feed can help restore flower and fruit production.
4. Leaf Discolouration or Spots
Unusual colours or patchy leaves can indicate a nutrient imbalance. Purple or reddish tints may suggest a phosphorus shortage, while dark veins with yellowing around them could mean magnesium is lacking.
5. Wilting Despite Adequate Watering
If your plant is well-watered but still wilting or looking limp, this could be a result of poor nutrient uptake. Feeding the soil or using a foliar feed can help revitalise it.
What to Do
- Use a general-purpose liquid feed for most plants.
- Choose a high-potash fertiliser for flowering or fruiting plants.
- Use slow-release pellets or compost in pots and containers.
- Always follow the feeding instructions on the label to avoid overfeeding.

Plants need food just like we do. Spotting the signs early and giving your plants the right nutrients at the right time can keep them strong, healthy, and productive. Not sure what your garden needs?
