This Portuguese native found its way into the U.S. via Australia in the mid-1800’s and it has remained one of the most popular and reliable lemon selections available ever since. It displays more heat, cold, and wind tolerance than other varieties. ‘Lisbon’ is just as ornamental as it is useful. The new leaves and flowers are tinged with purple and of course the blooms fill the air with their sweet fragrance. The vibrant yellow lemons are available year round but the heaviest harvest occurs between July and December.
Lemon trees are sensitive to overwatering, so water your lemon tree only when the top two inches (5 cm) of the soil have dried out and then soak your lemon tree with a generous amount of water. lemon trees require more water in the summer and should be watered less often in the winter to avoid root rot.
All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die. They need 12-14 hours of indirect sunlight.
As with most houseplants, they will benefit from an occasional feed during the growing season. An organic, balanced, liquid fertilizer once a month during spring and summer is recommended.
They ideally need a minimum temperature of 10°C (50°F); temperatures below 7°C (45°F) can severely damage or even kill the plants.
Whether it be plastic or clay, make sure the pot you select has drainage holes in the bottom to prevent over-watering.
