We grow lemons and mandarins in pots. Tui Citrus Food says not to use on plants in pots or containers. What should we feed our citrus in pots?

• It is “best practice” to not use blended fertilisers such as Tui Citrus Food on plants in pots and containers.
• Essentially fertilisers are salts and can potentially burn plant roots when over-applied.
• Tui Citrus Food is a blend of straight fertilisers with no control mechanism, the nutrients release all at once and are taken up by the plant and excess is washed out of the pot through leaching. 
• If fertiliser is over-applied to the soil, the soil acts as a buffer and the fertiliser disperses out into the soil.
• In pots and containers, when too much fertiliser is applied the concentration of fertiliser hits the pot wall and causes plant roots to burn. 
• Tui recommends either Tui Enrich Fruit, Citrus, Tree & Shrub fertiliser for plants in pots and containers, and Tui Citrus Food for plants in the garden. 
• In the growing season from spring through to autumn apply Tui Citrus & Fruit Superfood liquid fertiliser to plants in pots and containers weekly to promote healthy growth.
