Hollyhocks are not exactly considered easy to care for, but the care required is definitely within acceptable limits. This means that even beginner gardeners and gardeners with little time can dedicate themselves to this decorative plant and enjoy the abundance of flowers.
How often and with what should you fertilize hollyhocks?
Hollyhocks need fertilization 1-2 times a year if the soil is rich in nutrients, and 1-2 times a month if the soil is poor. In the pot they should receive liquid fertilizer every 14 days. Compost, horn shavings or manure are particularly suitable for planting.
Do hollyhocks need to be fertilized regularly?
Whether hollyhocks need to be fertilized regularly depends largely on their location. If they are in nutrient-rich soil, they only need a few additional nutrients. It is usually enough if you incorporate a little well-rotted compost or a little uric acid into the soil in the spring. A second dose in autumn makes sense if your hollyhock will only bloom next year or should bloom again.
The situation is completely different with hollyhocks that are cultivated in a pot or in a bucket. There is much less potting soil available here and therefore the nutrients are limited. You should fertilize these plants regularly. It is recommended to add fertilizer every two weeks. The situation is similar with hollyhocks, which are meant to grow in rather poor soil. They also need some support.
Which fertilizer is suitable for hollyhocks?
Matured compost or well-rotted manure is best suited as fertilizer for hollyhocks; they can be worked into the planting hole straight away, especially when planting. However, if your hollyhock depends on regular fertilization, then giving liquid fertilizer (€9.00 on Amazon) is easier to handle. You can simply mix it into the irrigation water.
The most important things in brief:
- when planting: add compost, horn shavings or manure into the planting hole
- for nutrient-rich soil: fertilize 1 – 2 times per year
- for poor soil: fertilize a little 1 – 2 times per month
- Add liquid fertilizer to the pot about every 14 days
Tip
Pay particular attention to the soil when fertilizing your hollyhocks. Over-fertilization doesn't make sense if the plant doesn't receive enough nutrients, then it blooms less luxuriantly and is susceptible to mallow rust.
