What measures to take to prevent pests from having pests?

The insects that cause pests are always there, lurking, waiting for the slightest opportunity to feed on plants that are not going through their best moment. During the spring, and especially the summer, is when we will see them most. However, there are several things we can do to keep them far enough away:

  • Keep the plants well watered and fertilized: bearing in mind that more is not always better; but rather the opposite in these cases as there could be a risk of overdose. If you do not want its roots and leaves to burn or dry out, water regularly and follow the instructions on the fertilizer container so that they are beautiful.
  • You do not wet leaves or flowers when watering: they cannot absorb the water directly, and in fact if they are kept wet too long they literally die, suffocated by having the pores on their surface closed.
    The same thing happens to the roots when you put a plate that is almost always full. Never forget to remove any excess water 20-30 minutes after watering.
  • Have diseased plants separated from others: in order to prevent pests or diseases from passing to those that are healthy.
  • Do not buy diseased plants: for the same reason mentioned before. If they have any pests, or they look bad, you have to leave them in the nursery.
  • Use new substrates: it is not advisable to reuse them as soil for potted plants (they can be thrown in the garden, in an area where nothing is planted), since the risk of infection is very high.
  • Disinfect pruning tools before and after use: in this way, you will keep the plants protected.
  • Do not hesitate to use chemical products when the plague is widespread: adopting the necessary safety measures, such as putting on rubber gloves, applying them only on non-windy days and if there is no rain forecast, and following their instructions to the letter. Why? Well, natural products are fine, but when we have a plague for example of cottony mealybugs that is killing plants, the ideal is to opt for chemicals such as insecticides that contain Pyriproxyfen.
