The Dipladenia, also called Mandevilla, is a so-called permanent bloomer with a long flowering period. For this reason, it needs a lot of nutrients, which are not sufficiently contained in the potting soil. Therefore, you should fertilize your Dipladenia regularly.
How should I fertilize my Dipladenia?
In order to properly fertilize a Dipladenia, organic fertilizer, such as compost or commercially available liquid fertilizer, should be added to the irrigation water about every one to two weeks. This supports a rich abundance of flowers and he althy growth.
How do I fertilize my Dipladenia correctly?
About once a week or every two weeks it's time to feed your Dipladenia with fertilizer. You can use organic fertilizer such as compost or nettle manure as well as commercial flower fertilizer. If you use liquid fertilizer, simply add it to the irrigation water. At least as important as the fertilizer is the right location for a beautiful abundance of flowers for your Mandevilla.
The Dipladenia likes it bright and warm, regardless of whether it is on the balcony or on the terrace. If it gets too little light, it will only bloom a little. Nevertheless, it only needs relatively little water. The soil should neither dry out nor be waterlogged. The Mandevilla doesn't do both well and comes at the expense of a rich abundance of flowers.
What happens if I don't fertilize properly?
If you fertilize your Dipladenia too little, it will affect its growth and flower formation. The plant may begin to worry. However, it is completely normal for some leaves to change color in summer and then fall off.
Too much fertilizer causes many plants to produce more leaves but few flowers. In addition, over-fertilization often makes the plants vulnerable to weather influences such as rain and wind. It therefore makes sense to only give small amounts of fertilizer and to fertilize more often. If you forget to fertilize once, don't add double the amount next time.
Caring for Dipladenia in brief:
- water only moderately
- don't let it dry out
- Avoid waterlogging
- fertilize about every one to two weeks
- fertilize throughout the flowering period
- Use organic or commercial fertilizer
