When April comes, the weather is unpredictable: frequent rain, gusty winds, hot days and cold nights. This phenomenon, so typical of spring, is perfectly summed up in the saying “April showers bring May flowers”. But how do these changes impact our bonsai?

April marks the final awakening of nature after winter. Bonsai trees, like all trees, enter a phase of active growth: new leaves sprout, stems lengthen and roots become active. But this process is constantly challenged by changes in the spring weather.

Heavy rainfall can cause excess moisture in the substrate, which can lead to the risk of rotting. In addition, sudden variations in temperature can cause stress, weakening the plant and making it more vulnerable to pests or fungi.

What signs should we look for?

  • Yellow or fallen leaves for no apparent reason.
  • Sprouts that are arrested in their development.
  • Fungi or spots on the trunk or leaves.
  • Unpleasant odour in the substrate, a sign of damaged roots.

These symptoms indicate that your bonsai may be suffering from the effects of an excessively wet or changeable April.

How to protect your bonsai during April

  • Control watering: do not water if the substrate is still wet.
  • Improve drainage: make sure the pot has good water drainage.
  • Avoid draughts and late frosts: place your bonsai in a sheltered place.
  • Watch for fungal growth: act quickly with antifungal products if necessary.

Despite the changes in weather this month, April is also an excellent time for transplanting, fertilising and shaping bonsai. If the right precautions are taken, this season can become an ally for the growth and health of your tree.

Now, these are just some of the points you should keep in mind for the perfect development of your plant, but they are not the only ones. You must not forget that you must use the necessary fertilizer so that the bonsai receives all the nutrients it needs, now that it is in the first phase of sprouting and in preparation for summer.
