I have recently purchased two large 110L planters. I want to grow strawberries in one and vegetables in the other. I have purchased some Tui Vegetable mix, Tui Strawberry mix and Tui Outdoor Container mix. I have now been told at my local garden centre that rather than filling the planters with the other mixes I should put a layer of compost (1bag) at the bottom and then put the vegetable / strawberry mix on top. What do Tui recommend for this situation?

• Both of these mixes are perfect for growing vegetables and strawberries in large planters.
• It is best practise to not use compost to grow plants in pots, planters and containers because as it breaks down it compacts and does not provide sufficient air or drainage for plants. 
• Compost is best used to dig into garden beds and replenish the organic matter in the soil.
• A cheaper potting mix can be used to fill the base of the planter and then use Tui Vegetable mix and Tui Strawberry mix around your plants. This will make it more cost effective especially if filling a large container.
• Tui Outdoor Container mix can be added as well as it contains water crystals for extra water retention to help stop plants drying out as quickly. 
• We recommend filling your planters with quality mixes, but if the budget doesn't stretch that far, it is okay to put a cheaper mix in the bottom and the Tui mixes in the top half.
