Ever get frustrated that your plants can’t stay with you for more than a couple of weeks from a disease you never saw coming? This post is here to save you from the worry of them targeting your precious plants again with these handy tips.

 

In order to choose your plant protection products wisely, you first need to identify what exactly is wrong with your plants. Below are the most common issues:

  • Insects – They bite or drill holes in the leaves, stem and fruit, and can cause serious damage or even death to your plant. They usually hide out on the underside of leaves, making it relatively easy to find them. To get rid of or ward off insects, you will need an insecticide.
  • Moulds – These attach themselves to your plants and feed on them. The first warning that you have mould is when you see any staining and discolouration on leaves and stems. To treat, you need a fungicide.
  • Excess nutrient or nutrient deficiencies – You will normally notice these only when the leaves change colour, as they tend to turn paler or yellow. To solve this problem, you will require fertiliser or a deficiency corrector.
  • Excess or lack of irrigation/ exposure to sunlight – If you haven’t found any bugs or noticed spots or stains, and the leaves are a good colour, then it may be that you need to water more or less, or provide more or less sunlight.

The critical thing is to identify the issue. Applying insecticide won’t help if your plant has mould, or vice versa.

 

The essential plant protection first aid kit

Let’s suppose you have ruled out any issues with watering, that the plant receives enough sunlight, and that you fertilise it regularly. In this case all you need is an insecticide and a fungicide, as well as a few targeted products that we will discuss later on.

It’s good to know that most of these products play a preventative as well as curative role. After all, prevention is always, always better than cure. As an example, in summer some regions are prone to torrential rains. This provides the ideal conditions for the appearance of moulds, as these thrive in heat and humidity.

After it rains, it’s a good idea to apply fungicide to your plants, as a preventative measure. This stops the mould or fungus spores from finding a suitable environment to settle in.

The same goes for insecticides. Have you ever noticed that the instructions tell you to reapply the treatment after a few days? That’s because many insecticides target the adult insects, but do not work on the eggs that may have been deposited on your plants. These will hatch after a few days, giving rise to a new generation of bugs that will continue to cause problems.

Earlier on we mentioned that apart from fungicide and insecticide, there are some targeted products that can also be essential to your first aid kit:

  • A molluscicide, or in other words, a product against snails and slugs. A must-have in any plant first aid kit if you have a vegetable patch or garden. Slugs and snails don’t tend to appear on terraces or balconies unless they hitch a ride on one of your plants.
  • If you have geraniums, we recommend keeping a specific insecticide handy that targets the larvae of the butterfly that this plant attracts. This is a very specific pest (also known as geranium drill) which targets this plant only, meaning you should be prepared if you want to keep your geraniums healthy and eye-catching.
  • An iron chlorosis corrector to combat a lack of iron in hortensias, camellias, gardenias and hibiscus, amongst other plants. The leaves begin to turn yellow, shrivel and then fall off.
  • Calcium-rich fertiliser for your tomatoes, especially if you’ve already suffered from apical-blossom end rot, as per the photo above.

How to apply plant protection products

Most of these products come in powder form for dilution, or directly in liquid form. To apply, you’ll need a sprayer as this allows you to spread the product uniformly over the leaves and stem.

If you only have a few plants at home, you can make do with a spray bottle, such as the ones for household cleaning. But we highly recommend getting yourself a pressure sprayer (available in 2, 5, 8 and 16 litres). These are really comfortable to use because by pumping the lever you can achieve enough pressure to spray the liquid without having to continuously pump. The nozzle is usually adjustable, allowing you to create small droplets that will be finely dispersed over the plants.

Larger pressure sprayers also come with a lance or wand, meaning you don’t have to bend down or come into direct contact with your plants. This is great not only in terms of comfort but also to keep you as far away as possible from the product being applied. Some products may cause respiratory problems, hence we recommend reading the manufacturer’s instructions carefully. We don’t want to scare you off, just warn you to take the necessary precautions and apply them 100% safely.

Let’s finish up with a couple of additional tips: try to apply your plant protection products at the start or end of the day, to avoid the direct sunlight over your plants. This will prove far more effective and convenient, particularly with organic products, as most of these are photosensitive, meaning they are less effective in sunlight.
When you’ve finished applying the treatment, release the sprayer’s internal pressure by opening the valve: this will lengthen its service life.
