In terms of temperatures, Allamandas are usually hardy only in the USDA zones 10 to 11. These plants do well in daytime temperatures of 65 to 80 °F (18-27 °C) and 59 to 65 °F (15-18 °C) at night. As a general rule, they will not tolerate temperatures that drop below 59 °F (15 °C). In regions with cool weather, you should grow your flowers in a conservatory, greenhouse, or indoors. Moreover, it is wise to protect them from cold drafts mostly during the chilling months.
Allamandas are pretty vulnerable to pests, especially when we are talking about mealybugs and aphids. If you want to know whether your plants deal with an infestation, you should first look at their foliage to see if it is healthy or damaged. In positive cases, make sure you treat your buddies with insecticidal soap once every week until the intruders are no longer there.
Allamanda plants will have the time of their life if you manage to plant them in a suitable growing medium. These plants will grow at their best in an acidic, peat-based potting soil that is rich in nutrients and organic matter. Likewise, you must plant them in a substrate that comes with excellent drainage. If you want to grow your flowers in pots, look for those that have drainage holes at the bottom or, otherwise, make them yourself.
Allamanda plants might seem very independent at the first glance, but they secretly dream about you giving them all your time and effort to make them happy. Due to this, your Allamandas will benefit from regular fertilizing throughout their active growing period. Feed them with a weak liquid fertilizer once every two weeks from spring through fall. In winter, it is more than enough to apply fertilizers only once a month or so.
Because most Allamandas are loose climbing species, they require some extra support to grow properly. Outdoors, make sure you plant your beloved flowers near a fence or other tall species of plants. If you grow them in pots, provide them with any organic support.
Allamandas have a tendency to grow and spread like crazy, so you may need to repot them regularly. When they seem to outgrow their pots, this is the perfect time to take action. Remove your plants from their growing medium and transplant them in containers that are one size larger than the current ones. Also, do not forget about adding some support if necessary.
Like most tropical species, Allamandas are big lovers of moisture. What makes these plants truly friendly is their ability to forgive you in case you over-water them, but only if you grow them in well-draining soil. How often you will water your flowers will depend directly on the region you live in, season, and weather.
During the summer months, you can water your Allamandas whenever the top layer of soil feels dry to the touch. Make sure you remove any extra water from their tray to avoid soggy conditions or waterlogging. Once the winter shows its chilling vibes, you must reduce the frequency of watering. However, you should not allow your plants to dry out completely.
Allamandas will not handle prolonged dry periods pretty well, but you can help them in a simple way. All you have to do is mist your plants once every two days or so to provide them with the needed humidity. During the cold winter, you can skip misting for good.
The easiest and fastest way to have more of these lovely flowers around is through propagation. Allamandas usually show nice propagation results if you are using stem tip cuttings. Moreover, to increase your chances of success, you must take the cuttings from fresh green shoots at the beginning of their growing season, usually in early spring.
Now that you have the Allamanda cuttings, dip their cut ends into a rooting hormone to help them grow faster. After this process, plant them in a container filled with fresh seed-starting potting mix. Place the pot in a warm, well-lit, and humid area. For optimal growth, provide the cuttings with some extra heat at the bottom.
With proper care, your Allamanda cuttings should develop a healthy root system in about one month or so. Once new growth emerges, you can transplant them in their permanent locations. Don’t forget to also plant a few cuttings in cute pots and gift them to your dear family members or friends!
It is quite difficult not to love Allamandas, especially when they are so stunning, low-demanding, and versatile. After all, why would you even want to resist their natural charm? Believe us, they are worth all the time and effort you will invest in them! Once you have one of the popular cultivars around, you will know that you have won the lottery ticket!
