A clay pot is ideal because unlike plastic it is porous and evaporates water from sides, this helps the lemon tree to grow well as it dislikes being waterlogged. The quality and type of potting soil is an essential factor as well. For growing high yielding plants, use well draining organic potting mix.

Temperature below 30°F (-1 C) is life-threatening for the lemon tree, except ‘Meyer’ lemon variety that can tolerate some cold till 24°F (-4 C).
Freezing temperatures succumb these plants to death. Optimum temperature is around 50°F to 82°F (10°C to 28°C). To overwinter it, keep your potted plant indoors or in a greenhouse when the temperature falls below 35°F (2°C).
Pruning and Pinching Lemon Tree
Pinching encourages bushier growth, pinch growing tip when a branch is about 5 inches long. Pruning of lemon tree is best carried out when new growth starts (February – March). Be careful before pruning it, only prune diseased or dead branches because lemon stores excess food in its leaves and too much pruning can result in poor fruit crop. Also, keep looking for suckers and prune them immediately if found one.
Fertilizer for Growing Lemon Tree in a Pot

Look for a fertilizer that contains micronutrients, especially iron, manganese, and zinc. To give boost feed to your lemon tree apply a water-soluble fertilizer once in a month in growing season. Occasionally, side dress your plant with compost or well-rotted manure.
