Comment entretenir les dahlias en pot ?
Fertilisation. Le Dahlia est un vorace, plus encore lorsqu'il est cultivé en pot ! Le substrat en pot s'épuisant plus rapidement qu'en pleine terre, apportez un engrais pour plantes à fleurs à l'eau d'arrosage, tous les 15 jours de juin à octobre, afin de favoriser la végétation.
Quelle exposition pour des dahlias ?
Sol et exposition idéals pour planter un dahlia au jardin ou en pot. Le dahlia apprécie un sol profond, riche en humus, sain, plutôt humifère et bien drainé. Une exposition à la fois chaude et ensoleillée fait son bonheur.
How do you take care of dahlias in pots?
- Keep the pot in full sun. Water the tubers deeply once the stalk extends above the rim of the pot. Give them a thorough watering 2 or 3 times a week. Dahlias growing in hot, dry climates may need daily watering. While you should water thoroughly and keep the soil moist, the soil shouldn’t be soggy or waterlogged.
How deep do you plant dahlias tubers?
- Planting Dahlia Tubers. For most dahlias, you want a fairly large pot, though it doesn't need to be very deep. Many varieties would do well in a 12 to 14-inch diameter pot which is also at least 12 inches deep. Also, make sure the pot has good drainage because the tubers will rot if left to sit in water.
How long does it take for a dahlia to grow?
- As the stalk grows, continue adding small amounts of soil until 1 inch (2.5 cm) of empty space remains between the top of the soil and the rim of the pot. Dahlias grow quickly, and you’ll see substantial foliage within 2 weeks. Blooms typically appear about 8 weeks after planting.
Do dahlias like full sun or shade?
- Dahlias like full sun, though don't like to get searingly hot. If you live in a warm climate or your pot is in a hot spot (in a corner or on concrete where the surface gets hot) move your pot into a shady spot during the heat of the day. Keep the soil moist, but not wet.
