How can I rid my Dipladenia of the lice?
Head lice can be easily combated with home remedies or biological measures. Even hosing it off with a powerful jet of water is often sufficient. Optionally, a solution of soft soap (44.90€) or nettle manure also helps, but these do not necessarily smell pleasant.
How can I prevent a head lice infestation?
The best way to prevent lice infestation is to give your Dipladenia the opportunity to grow vigorously and healthily. So, as in its homeland, it should be warm and bright without being exposed to the blazing midday sun for hours. To be on the safe side, check your plants regularly for aphid infestation, so you can react quickly in an emergency.
Too much or too little water affects the health of the Dipladenia and makes them more susceptible to lice infestation. During the flowering period, the Mandevilla also needs fertilizer regularly, because flowers cost you a lot of energy.
The essentials in brief:
- Check regularly for lice infestation
- react immediately in the event of an infestation
- preferred time for a lice infestation: from early summer
- Fight lice biologically if possible
- Hose down with water, soft soap solution or nettle manure
- keep warm and bright to prevent infestation
- enough, but not too much water
