Hydrangeas have special soil requirements and should therefore be fertilized regularly. As an alternative to liquid fertilizer, there are a number of home remedies for fertilization.
Which home remedies are suitable as hydrangea fertilizer?
Hydrangeas can be fertilized with home remedies such as coffee grounds, manure, vegetable water or compost. When choosing fertilizers, pay attention to iron, potassium and a low pH value. The latter ensures that the minerals can be optimally absorbed by the hydrangeas.
Can hydrangeas be fertilized with home remedies?
Hydrangeas need a lot ofnitrogen and iron for good growth. If they do not receive enough of the mineral, the flowers may be less lush. Normal fertilizers are therefore rather unsuitable. Acid soil is a prerequisite for good absorption of nutrients. The more acidic the soil, the better hydrangeas can absorb necessary nutrients.
How do I fertilize hydrangeas with coffee grounds?
Coffee grounds are particularly suitable for fertilizing wild hydrangeas in beds. Since its mineral content is rather weak, it is less suitable for heavier hydrangea species and potted plants. There it should only be used as a supplement, never as a sole fertilizer. Coffee grounds have the property of making the soil acidic, which makes hydrangeas grow better. Loose tea can also be used as an alternative to coffee grounds. Green or black tea is best. Caution: Never give hot coffee grounds or tea to your plants. Always let it cool down first before you work it into the soil.
Which home remedies contain potassium?
Hydrangeas can also be fertilized from time to time with amanure made from dandelions or nettles. This contains a lot of potassium and covers the high needs of hydrangeas.
Can hydrangeas be fertilized with cooking water?
Water that is produced whencooking vegetables and usually ends up in the drain is also ideal for light fertilization of hydrangeas. It contains all the minerals that are released from the vegetables during the cooking process. Make sure that the water is uns alted, otherwise it is unsuitable for fertilization.
Can I fertilize hydrangeas with compost?
Compost is suitable as a hydrangea fertilizer. It contains valuable minerals and nitrogen and, depending on its composition, it can also contribute to a low pH value in the soil. For example, adding oak leaves can lower the pH value of the compost, allowing the hydrangeas to absorb the minerals better.
Should you water hydrangeas with apple cider vinegar?
Apple cider vinegar is a popular household remedy for various applications, but it should only be used very carefully in the garden. Similar to coffee grounds, it contains valuable minerals and can be used to make the soil acidic. However, because of its significantly lower pH value, it can quickly upset the balance of the substrate.
How often should hydrangeas be fertilized?
Hortensas in pots should be fertilized everyone to two weeks. Weak fertilizers from home remedies can be added a little more often. For hydrangeas growing in beds, it is sufficient to fertilize once in spring and once during the growing season in summer.
The bushes only absorb as many nutrients as they need, so they cannot beover-fertilizedwill be. Nevertheless, you should dose the fertilizer correctly, for example to prevent coffee grounds from starting to mold.
Tip
Coffee grounds also act as a pest repellent
Coffee grounds are not only an excellent fertilizer for hydrangeas. Due to the caffeine it contains, it is also ideal for repelling pests.
