The name "grapefruit" comes from the fact that the bright yellow fruits ripen like grapes in tightly packed clusters.
Nutrient soil is best prepared from a mixture of soddy and leafy soil, humus, peat and sand in a ratio of 2: 1: 1: 1: 1. And grapefruit needs a lot of nutrition: these are all macro- and microelements. Iron is especially important. Therefore, when planting, put a couple of rusty nails in the ground.
Many varieties and indoor grapefruit are known, but Duncan is recognized as the most popular. It begins to bear fruit in the fourth year after grafting. Fruits (up to 500 g) are large yellow, slightly flattened. At home, grapefruit feels good.
In spring and summer, grapefruit should be watered daily or every other day; in autumn and winter, watering is reduced (subject to cold wintering) to 1-2 times a week. The same is true for air humidity. In the warm season, we recommend spraying the crown of the tree daily and ventilating the room with the plant.
You need to feed grapefruit only in spring and summer, using complex fertilizers for citrus fruits. You can apply both root and foliar top dressing, however, in the second case, it is absolutely impossible to spray the leaves and fruits of the tree with a solution. Grapefruit transplantation is carried out every 2-3 years, partially replacing the ground.
