Garden Plant Advice


Why are my plant leaves turning yellow? It’s an age old question! If you’ve ever seen yellow leaves on your what-was-once-green-plant, read on to find out the causes, symptoms and solutions. It’s all going to be fine!

We might not be able to lip read, but plants have a pretty good way of telling us what’s making the plant unhappy. Among the reasons plant leaves are yellow are environmental conditions, plant care, pests or disease, and even the medium that the plant grows in.

Yellow leaves on plants mean different things depending on (A) the variety plant, and (B) what other symptoms the plant is showing. Overwatering, under-watering, mineral deficiency, temperature stress, and so on can all be causes. So, to simplify we have jotted down our top symptomatic combinations with a solution to get rid of yellowing leaves on your plants.

plant leaves dry and crispy = your plant is thirsty

There is often a middle stage between the plant leaves turning brown, the leaves and stem will start to droop which is the best moment to water and recover, but sometimes the lower leaves and stem are still active and will prompt regrowth. If you're planting in pots outside you may want to consider placing pots together in the summer heat to keep them cool.

no new growth = your plant is thirsty

If your plant is looking a little skimpy, chances are you need to up your watering schedule moderately and reassess how much light is hitting it’s leaves.

yellow leaves at the edges = your plant is overwatered

Try watering less frequently, but do not stop all together. In time, you’ll get to know the rhythm of your plants and how often they need a drink, the knuckle test is our normal go to for watering. Place your finger into the tip of the soil, if it’s wet the plant hasn’t absorbed the last lot and can skip a drink.

plant is dropping leaves or discoloured = overwatered

It’s the number one killer of plants, and it’s not just the watering can. If you have planted in pots, you’ll want to check your plant has adequate drainage and holes in the bottom. Plants aren’t generally big fans of sitting in water so always look to make sure the pot hasn’t turned into a bath.

they’re looking a bit pale = hungry

Feed your plants with some liquid fertiliser, sometimes they just need some more iron - especially if you know you have poor soil or using containers. You can move the plant into a new, slightly bigger pot with some more soil if you need some.

The best feeling is seeing your work pay off and soon with your adjusted routine you’ll see some new green leaves.
