The Dipladenia, also called Mandevilla, is a so-called perpetual bloomer with a long flowering period. For this reason, it needs a lot of nutrients that are not sufficiently contained in the potting soil. Therefore, you should fertilize your Dipladenia regularly.
The Dipladenia needs a lot of nutrients
How do I fertilize my Dipladenia correctly?
About once a week or every two weeks, it's time to fertilize your Dipladenia. You can use organic fertilizers such as compost or nettle manure as well as standard flower fertilizer. (€1.95) Take liquid fertilizer and then simply add it to the irrigation water. At least as important as the fertilizer is the right location for a beautiful abundance of flowers in your Mandevilla.
The Dipladenia likes it light and warm, regardless of whether it is on the balcony or terrace. If you get too little light, then it will only bloom a little. Despite this, it only needs a relatively small amount of water. The soil should neither dry out nor be waterlogged. Both are not good for the Mandevilla and are at the expense of a rich abundance of flowers.
What happens if I don't fertilize properly?
If you don't fertilize your Dipladenia enough, this will affect their vigorous growth and flowering. The plant may begin to worry. On the other hand, it is quite normal for some leaves to change color in summer and then fall off.
Too much fertilizer will cause 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. Therefore, it makes sense to give only small amounts of fertilizer and to fertilize more often. If you forget to fertilize once, don't give twice the amount the next time.
The care of the Dipladenia in brief:
- water only moderately
- don't let it dry out
- Avoid waterlogging
- fertilize about every week or two
- fertilize throughout the flowering period
- use organic or commercial fertilizers
tips
Supply your Mandevilla regularly with organic fertilizer or commercially available flower fertilizer, then you can enjoy a rich abundance of flowers all summer long.
