Dahlias are bulbous plants native to Mexico that can be grown both indoors and outdoors. They can reach a height of one meter, but the smallest species are about 30 cm tall.

The white dahlia has very large flowers and an intense white color. If the weather is very hotthe dahlia can flower after summerwhen the temperature is softer and more pleasant for her, that is, already in autumn.
Although they tolerate the cold, protect them from night frosts. The ideal is to plant them first in pots and in a protected place before transplanting them into the garden. The soil must be fertile, rich in humus and well drained. Dig a hole of about 50 cm, with the growth point of the bulb facing up, cover with soil and compost, water, do not flood. Once every three weeks is enough.
It is recommended to plant dahlia bulbs in stages from February to the end of May. This way you will have flowers both in winter and in summer. In late fall, clean and store the tubers in a cool, dry place. They will keep until spring. Make sure the eyes of the tubers are facing up, don’t water them until you see them start to sprout, then water 3 times a week.

lighting and positioning
These plants need very bright places to grow properly, especially when we want to enjoy their beautiful flowers. Place the dahlia in a well-lit spot in the garden, or if you keep the dahlia indoors, next to a window or point of light.
You should place these flowers in semi-shade, or at least where they are protected from the strongest and most dangerous influences, only when the sun in your area is very intense, which is usually noon.
Also, the wind can do a lot of damage to your dahlias, so it is necessary to find a place for them that is as sheltered as possible in this regard. If you can’t protect them from him, teaching them is a very good idea.

Cover the base and bulbs with a thick mulch, or remove the dahlia bulbs if temperatures are very cold. You can always store them in a protected and dry place to replant them when the frost has passed.
The white dahlia likes to grow in soil rich in organic matter. As always, we recommend using organic and ecological fertilizers such as worm humus, compost and bokashi. Both are very rich fertilizers that will keep your plants free of synthetic chemicals.
To prepare the soil, remove the soil or substrate before planting to loosen it and allow for the best possible drainage. Give it strength with the fertilizers that we have mentioned. The fertilizer is renewed every winter, with a small monthly dose during the warmer months. After planting dahlias, secure the soil over the bulbs and water.
Watering the white dahlia

The flowers are headless and, as the name suggests, consist of a stem that cuts through the bud to produce the seed. In this way, the plant does not spend as much energy producing these seeds and helps to create new flower buds so that flowering lasts longer.
