Growing and Caring for Cantaloupe

Now that we have seen when and how to sow and plant cantaloupe, let’s proceed to see the necessary care to take into account for them to develop properly. Follow these indications if you want to know how to plant cantaloupe successfully:


One of the most important points to take into account for the correct development of the cantaloupe is the temperature because it must be warm enough. This plant is very sensitive to low temperatures, and if you want your melon tree to develop well and bear good fruits, you must keep it between 73.4Β°F and 86Β°F (23 and 30ΒΊC). For this reason, it is important to dedicate a location with good lighting. Additionally, on cold days you can cover the plant with some type of plastic or tarp that will not crush it and will help it maintain a stable temperature.


Cantaloupe has huge water content. With this in mind, it is not hard to imagine that the plant needs a good supply of it to grow healthy and bear large fruit. In the warm months, water your cantaloupe plants daily, making sure that the soil is always moist and does not dry out completely. In the cold months, you can space watering a little to prevent the soil temperature from dropping too low.


Cantaloupe is very demanding when it comes to soil nutrients. They need soil rich in organic matter, fertilized with compost or humus twice a month in the warm months, and once a month or every two months in the cold months.


Although we have already said that this plant needs a lot of water, the soil mustn’t become waterlogged at any time. That is why we recommend that you provide good drainage to the area where you plant cantaloupe.

When to Harvest Cantaloupe
