How to irrigate
As regards the correct irrigation of the Buddleia, it is necessary to proceed with great caution. This plant, in fact, does not like too moist soil and prefers drought. Therefore, it is advisable to irrigate our Buddleia only during the summer months and also occasionally. When you intend to proceed with a new irrigation, it is essential to carefully check the soil. Should it still be damp from the previous wetting, it is not recommended to irrigate to avoid water stagnation. These stagnations could, in fact, submerge and asphyxiate the roots causing root rot, one of the pathologies that lead the plant to a quick death. Irrigations should be suspended completely during the winter months as the buddleia It is able to withstand thanks to seasonal rains.
How to cure
The Buddleia is a plant that loves a rather sunny exposure. In order to ensure copious flowering, it is good that the plant can enjoy sunlight for at least a few hours a day. Furthermore, the Buddleia does not particularly fear the cold. In the case of too cold temperatures, in fact, the plant is able to lose all the aerial part and to regenerate it during the following spring. As far as pruning is concerned, some types of Buddleia should be pruned before flowering, while others should be pruned later. However, for any type of Buddleia it is essential to remove withered flowers in order to prolong the duration of flowering. For the multiplication one can proceed by sowing in winter in a warm bed. Although the first plants will begin to appear during the summer, it is good to wait for the following year to plant them.
How to fertilize
To fertilize the Buddleia correctly, it is necessary to proceed with a specific fertilizer for flowering plants. This fertilizer can be supplied to the plant in liquid form by diluting it with irrigation water in slightly lower doses than reported on the package. It is recommended to choose a fertilizer that contains the three fundamental chemical substances such as: nitrogen, phosphorus and potassium. In addition, it is possible to supply Buddleia with lower doses of chemical microelements such as: copper, magnesium, iron and zinc. This fertilizer can be supplied to the plant just before the start of the growing season. As for the soil, instead, the Buddleia is a plant that can adapt to any substrate. However, to help and promote its growth, it is good to provide a fresh and well-drained soil.
Buddleia: Diseases and exposure
Buddleia is a rustic plant and for this reason it is hardly attacked by pests or insects. Rather, it is possible for the plant to experience physiopathies, or problems caused by poor cultivation. Among these, it is easy to cause root rot through water stagnation generated as a result of excessive wetting. In this case, there is nothing to do if the whole root system is completely rotted. However, if only some of these roots are still safe, it is advisable to amputate the others and then let the plant dry. Furthermore, if the Buddleia is not properly exposed to the sun, it is possible that the bloom will be scarce and not uniform. In this case, it is recommended to simply reposition our plant in a more suitable location.
