Pumpkin and zucchini

Pumpkin is a hard-shelled berry, highly valued in virtually the entire world for its great nutritional value. Gastronomies around the world use pumpkin for its flavor and nutrients, particularly popular in pastry.

Something that not everyone knows is that zucchini is nothing more than a type of immature pumpkin, collected before the skin hardens. In some species, the immature fruit is toxic, although others, among which are obviously those that are marketed as such, are perfectly suitable for consumption. These are in fact, along with cucumbers, the most popular edible-skinned cucurbits.

Cultivation of cucurbits

Here are some basic indications for the cultivation of cucurbits :

  • Most cucurbits are best planted in seedbeds, to later be transplanted to their final location once the seedling is not so susceptible to weather conditions.
  • This is the case of plants such as squash or cucumber, whose seedlings can be planted in mid-winter, to be transplanted in spring, once the frosts and cold have passed. Others, however, such as melon and watermelon, are usually planted at the beginning of spring, respecting at least one meter of distance between plants and being able to be harvested between mid and late summer.
  • Cucurbits are not demanding with the soil, but they do require good drainage and regular waterings that maintain humidity so that they can fatten their large fruits.

Pests and diseases of cucurbitaceae

Cucurbit diseases and pests are well known due to their widespread cultivation, and this is probably their weakest point.

Excessive irrigation, or poorly managed irrigation that causes flooding, can frequently cause diseases such as powdery mildew in cucurbits , which can be fought by keeping humidity controlled with drip irrigation or looking for a sunnier and better ventilated location. Here you can learn more about how to combat powdery mildew with home remedies .

In a similar way occurs with mildew in cucurbits , another fungus that appears when there is excessive humidity, poor aeration and temperatures between 10ºC and 20ºC. Pruning to improve plant ventilation can help in these cases. Here we tell you more about How to combat mildew .
