Care Of Fruit Trees in The Orchard in May

Fruit trees also have their protagonism, the month of May is the optimal season, you can plant a variety if you already have them in seedlings, especially those of deciduous leaves because they are already rooted and ready to be transplanted.

During May, some fruit trees will continue to bloom and in others, the first fruits will begin to form. Special care should be taken to avoid aphid infestations that affect many fruit trees. To control aphid infestations, you can use effective and environmentally friendly ladybugs.

At this time, fruit trees need more watering, so you will have to water them additionally if there is little rainfall during May.

Tips For the Plant in May

With fruit trees you must be very careful so that they can have a strong and healthy development, you must note in the calendar the following recommendations:

Sow and Plant in May

This is the optimal period for sowing because the seeds and seedlings adapt perfectly to the climatic conditions due to the onset of spring.

Select the Method to use for Sowing

You may want to keep the seedlings for a longer time to protect them either from a straggling frost, strong wind, or inclement sun.  This is very favorable because the seedlings get stronger when the time for transplanting arrives.

Now if you are going to plant the seeds directly, it is good to know the depth of sowing, that is to say, to know how deep the seed will be buried: if it is too deep it will not receive enough sun and if it is too shallow it is possible that it will be easily seen and the birds will eat it. Consider the time it will take to germinate.


Plants in seedbeds, as well as those planted directly in the soil, require normal watering, which means that they should never lack water because when they receive the sun’s rays the soil will lose its humidity and the plant will be damaged.

Some plants require more water than others, therefore abundant watering should be periodic for this type of plant, it could be said that daily but without flooding them.

Ideal Planting Location to Plant in May

The condition of light or shade for fruit plants is very important because it will depend on the position in which they are planted or placed.  Some plants are resistant to direct sunlight, while others do very well when they receive sunlight but also have shade.  At the time of planting, it is good to keep this in mind.
