Jacob's ladder gets by with little care
The Jacob's Ladder (Polemonium caeruleum), also known as Blue Sky Ladder, impresses with its bright blue (in some varieties white) flowers with bright yellow stamens. The very vigorous, group-forming perennial grows up to 90 centimeters high and is one of the typical farmer garden plants. Planted in the right location, Jacob's ladders require little care.
At what location does the Jacob's Ladder feel comfortable?

Jacob ladders have a fairly high water requirement and are very difficult to cope with longer periods of drought. Regular watering is therefore essential, especially in summer - especially in sunny locations. If necessary, water the plants both in the morning and in the evening, but the flowers should not be watered. A mulch layer helps to keep the soil from drying out.
Do you have to fertilize the Jacob's ladder? If yes, when and with what?

It is sufficient to supply the shrubs with compost at the beginning of the growing season (around March / April, depending on the weather). These gifts can be repeated several times throughout the summer. Jacob ladders in the planter are fertilized with liquid fertilizer. Be careful not to put the fertilizer on the dry root ball.
