Please note: plant heights are approximate and are provided for indicative purposes only. Plants suitable for hanging may be depicted in a hanging grow pot, the actual grow pot used to ship the plant might not include these attachments. For hydroculture plants use the size tip to select a decorative pot that will accommodate the waterproof liner recommended for the plant in the hydro kit.

In winter, when plants are indoors, allow the surface of the compost to partially dry out before watering, then water thoroughly with tepid rainwater, allowing the excess to drain away. Overwatering in winter is one of the commonest problems, so err on the dry side. And never leave pots standing in water, as this can cause the roots to rot. Yellowing of the leaves or shedding leaves can be signs of overwatering. Gradually move them from a partly shaded spot to one with full sun, eventually setting them in the sunniest spot you can find. Provide protection from wind, and keep the pots in their saucers to maintain good drainage. Hydroculture plant roots have been specially adapted to grow in hydrogranules, which creates a smaller, more fleshy and hardier root system. This results in mature plants being available in smaller grow pots than their soil based equivalents. How do I choose the correct sized decorative pot to fit my houseplant? Citrus plants aren’t generally hardy in the UK, even though some may be marketed as suitable to grow outdoors in a warm location. A few can tolerate temperatures down to 5°C/41°F (such as some lemons), but others need at least 13°C/55°F (such as calamondins). So they are best kept in greenhouse, conservatory, glazed porch or similarly bright frost-free location over winter, if not all year round. Make sure you have the right conditions for them before you buy. If you are able to move plants into the bathtub or onto the porch, a strong spray of water can often be enough to remove pests, including any honeydew and accompanying mold. Make sure to spray the undersides of leaves.Soil Depth: When repotting allow a little room for the roots to spread. The soil should not be so shallow that without drainage the roots will sit in water, nor so deep that the water drains below the roots leaving the plant to dry out. Citrus is best grown in air temperatures between 55 and 80°F. Keep in mind that ideal temperatures vary between species. You can also make a homemade insecticidal soap by filling a spray bottle with water, a couple of teaspoons of mild biodegradable soap, and a teaspoon or two of vegetable oil. Spray the foliage every few days, as long as the infestation persists. Light is also very important for citrus plants. For the best growing citrus plant, the plant needs at least 5 to 6 hours a day of direct sunlight. Try placing your plant on a south-facing window sill as this seems to provide the right amount of light. Citrus plants are good to grow as a houseplant because they thrive in the stable warmth that is provided indoors. Citrus plants grow best with temperatures at 18°C during the day, and between 5°C and 10°C at night. In summer, these houseplants can be moved outdoors once the risk of frost has passed. However, as soon as it becomes cold they need to be moved indoors. Also, some citrus plants are more fragile than others. For example, lemon trees can tolerate temperatures down to 5°C, whereas limes can only tolerate temperatures down to 10°C and Calamondin oranges only 13°C. Depending on the type of citrus plant, determine when or if you should move it outdoors in the summer, based on this information.

Fill in around the edges with more Citrus Potting Mix ensuring the top feeder roots are covered with 2cm of fresh potting mix Bring them outside once the air temperatures are consistently above 50°F, transitioning them to their new conditions over a period of a couple of weeks. There is a huge range of citrus plants to choose from, including lemons, oranges, mandarins, limes, grapefruits, kumquats, limequats, calamondin oranges, tangelos, citrons, kaffir limes and more. Some varieties produce fruits that can be eaten straight off the tree, while others are just for cooking or for juice. Usually caused by fungi from the Phytophthora genus, root rot is often a result of overwatering or allow your tree to sit in waterlogged soil. Pot size is also a consideration – if small trees are planted in a pot that’s too big, this can lead to excess moisture remaining in the soil.A frost-free greenhouse may be suitable for some, but others may need warmer conditions, such as in a conservatory. A few lemons , for example, will be fine as low as 5°C (42°F), kumquats often need 7°C (45°F) or more, limes and grapefruits should be kept above 10°C (50°F) and calamondin oranges may need at least 13°C (55°F). Centrally heated homes are usually too warm in winter, and the air tends to be too dry. To prevent insects from getting out of control, keep citrus away from other houseplants, vents, doors, and window screens, and always give them a thorough rinse before moving plants indoors for the winter.

For plants in soil the key size in determining the maturity and fullness of a plant is the diameter of the grow pot. The larger the diameter, the more mature the plant. How do we size hydroculture plants?

The grow pot height is standardised (normally 12cm or 19cm) and shown on the size option for each hydroculture plant. Ensure the external height of your decorative pot is at least 2-3cm higher than the grow pot height of the hydroculture plant. Note: If the shape of the planter tapers strongly at the base, it might not be wide enough for your plant to sit squarely at the bottom. In this case you can add a liner on a small layer of pebbles to increase the size of the base. This will however raise the height of the plant slightly in the planter. Cool or fluctuating temperatures, dry air and cold draughts can cause citrus plants to drop their leaves, fail to flower or not produce fruit. Note: Liners are "squashy" so they can be pushed through the opening to expand and fit closer to the pot wall once inside. Liners can also be cut down to size with scissors for a neater fit if they bulge inwards slightly at the top. Liners come in various sizes to fit the internal dimensions of the pot and can be trimmed down to size to create an unobtrusive barrier for the plant and soil to be potted into, whilst protecting the pot from unsightly calcium or fertiliser deposits from the soil.
