Why Are My Outdoor Plants Dying?
There are several causes which may lead to your outdoor plants dying. Some are more common than others, and there is no one size fits all solution to bringing your plants back from the brink of death. With the proper care and maintenance, you can prevent possible issues leading to your plant dying. However, once a problem or issue has occurred, you need to know the right course of action to fix it.
6 Common Outdoor Plant Problems
Before we find the solution, we need to diagnose the problem. There are many problems outdoor plants face, and we have listed the most common you may encounter. Work through our list to find the issue causing damage to your carefully kept garden and find the answers to problems you may face. When it comes to your babies, plant parents must be prepared for any problem, and Dr Fingers is here to help you get equipped.
1. Black Spots
Seeing black spots on the leaves of your beloved plants can be alarming, almost like watching our plants die right in front of our eyes. More commonly, this problem affects roses; however, all leaf plants can exhibit this symptom.
Typically, black spots on leaves indicate a fungal disease brought on by a combination of warm and damp weather. Think about those humid summer days. Once black spots have developed, the leaves will turn yellow and eventually drop off, leaving you with a bald plant unable to photosynthesise.
You should position your plants in garden areas with good air circulation to prevent black spots from taking over your plant leaves. This means avoiding corners where your plant may be boxed in and out of the summer breeze. On top of this, ensure you don’t over water your plants and keep them in a good position for sunlight.
2. Powder Mildew
Are you a veggie lover with your garden filled with vegetable plants? Nothing is more satisfying than watching the seedlings you plant grow delicious and ripe vegetables. But first, you have to make sure they survive to be able to sprout. A common problem outdoor vegetable plants face is the appearance of a powdery type of mildew.
More commonly, this mildew will affect melons, squash and cucumbers; unfortunately, once it has appeared, there is no cure. But you can control it and limit the spread to salvage your vegetables. You can limit the spread by picking off any affected leaves you spot and spraying the plant with a fungicide. If you have none to hand, you can also create a mix of milk and water to spray on affected plants.
3. Blossom-End Rot
Powdery mildew is not the only terror affecting your vegetable plants. The appearance of blossom-end rot on your botanical fruits is equally as alarming. Unfortunately, there is no saving pieces that have been affected. This means you should remove affected fruit from the plant and discard it, do not attempt to eat these.
Botanical fruit, or culinary vegetables, commonly affected by blossom-end rot include tomatoes, peppers and eggplants. It appears as a dark, rotting spot at the bottom of the fruit and is caused by a calcium deficiency resulting from a lack of soil moisture. Luckily, the rest of the plant can be salvaged once affected fruit are picked. Simply make minor adjustments in your watering routine.
In the summer, a lack of water can wreak havoc on your garden. Of course, we all know that plants need water to thrive, and some are more thirsty than others. If you’re concerned that summer has been a dry period for your plants, you can boost their reliance on dry weather with compost. You may also want to mulch your garden to help keep the soil moist and the surface layer from baking and becoming dry under the summer sun.
Suppose you’re concerned that work and other commitments will keep you from regularly watering your garden in summer. In that case, you may also want to consider a timed hose, sprinklers or other automatic watering function.
On the reverse of drought, it is also possible for your garden plants
Rain off the back of particularly hot days can be heavy, and the flood of excess water in your garden can suck the nitrogen out of your plants. This will leave your leaves starved for nutrients and become yellow. The solution? Create the best possible drainage for your garden plants by adding gravel to the bottom of plant pots. This allows excess water to drain freely through the drainage holes in your pots.
6. Aphids Infestation
If your plants look weak and frail, it might not actually be your own doing. In Britain, more than 500 species of aphids are found in all parts of the country, according to The Royal Society for the Protection of Birds (RSPB). These small bugs infest quickly and drink the sap from your plants, leaving them distorted, warped and weak as they cannot thrive. On top of this, aphids will also excrete a sticky, black honeydew which will cover your leaves in black mould. So, while these bugs need plants to survive, they are unforgiving of their habitats.
If you notice symptoms of an aphid infestation, you can usually spot these small, pear-shaped bugs with the naked eye. If the infestation is large, you should allow nature to take its natural course. Usually, aphids will build strong colonies in the spring. Still, by late summer, natural predators, such as ladybugs, earwigs and hoverflies, will be active and remove the pests for you.
To prevent these bugs, keep an eye on your plants and stamp our infestations before they become out of control.
