The lemon cypress tree, known scientifically as Cupressus macrocarpa, is a shrub-like plant. In the United States, it is native to California, while in Europe, it is native to Italy. Lemon cypress trees grow best in warm temperatures where rain is frequent and sunlight is abundant. Blue and silver lemon cypress trees prefer a little shade, while the yellow lemon cypress prefers all sun.
Keep your lemon cypress tree near a window where light is plentiful. During colder months, consider using a light box to give it light. Keep the soil moist, especially during the winter. According to Indoorplantcare.com, new lemon cypress owners often make the mistake of watering their trees using only tap water. The lemon cypress needs water with properly measured fertiliser for nutrition.
Lemon cypress trees are accustomed to a fair amount of heat. About 20 degrees C is best. Caring for a lemon cypress outdoors requires maintaining a frequent watering schedule and ensuring that the tree is properly fed and trimmed. Indoorplantcare.com suggests planting lemon cypress in a somewhat acidic mixture of compost. Adding a little clay or sand to already fertile soil will keep your lemon cypress growing year after year. The website also recommends spraying at the first sign of aphids, which leave a black, sooty substance on the tree. This damage can occur quickly, and a lemon cypress may take several seasons to recover from an infestation.
According to Topiaryshop.co.uk, one important but often overlooked step in lemon cypress care is proper pruning. The site suggests using sharp blades to keep the shape of the tree intact, as leaving the lemon cypress to grow unmaintained will cause it to go brittle quickly and die. When you first receive the plant, pay close attention to the patterns in which it grows. The lemon cypress is naturally triangular in shape and should be kept that way.
