Canna Lily 'Yellow King Humbert'

• On Arrival: Unpack your three bare roots. Start them in March-April; if received earlier, keep them cool and frost-free in barely damp compost until spring.
• Potting Up: Plant each bare root in a 20cm pot of multipurpose compost, just covered, with shoots exposed. Water lightly and keep somewhere bright at around 10-16C. Increase watering as growth develops.
• Planting Outdoors: Gradually acclimatise plants to outdoor conditions, then plant after the last frosts, usually late May-June. Choose full sun, shelter and fertile, well-drained soil. Plant rhizomes around 10cm deep and 75cm apart. For containers, allow a pot at least 30cm wide per plant.
• Watering And Feeding: Water regularly during growth, keeping compost moist without waterlogging. Add controlled-release fertiliser to containers at planting, then use a high-potash liquid feed in summer according to its instructions.
• Winter Care: Move pots under frost-free cover. Lift border plants as foliage withers, cut stems to 15cm and store rhizomes in barely damp compost somewhere frost-free. Water very sparingly while dormant.

Please allow us 3-5 working days to dispatch your order. Pre-ordered items will be sent as soon as possible after the date quoted and we'll generally ship your entire order with your pre-ordered items. When your order is dispatched, we'll send you another email with details of how to track it.

Most orders are sent on a fully-tracked courier service with Yodel. To avoid perishable items being stuck at depots and deteriorating, no signature is required, and our courier is asked to leave your order in a safe place on your property.

We'll send a tracking link when we dispatch your order, so you know when it's due to arrive. Please note, once delivered we cannot be held responsible for loss or theft from your property. If you have any specific delivery instructions, please let us know - there's an option to enter a short message for the courier at the checkout.

Smaller, lighter, single-item orders may be sent through the post with Royal Mail - in which case no tracking is available.

Our experienced nursery team will always send your plants nursery fresh in the perfect condition to thrive when you plant them, so although most plants are very tough and will not be affected by all but the most extreme frosts or heatwaves, we avoid dispatching the most perishable plants if extreme weather is forecast, or over Bank Holiday weekends.

Please note, we cannot guarantee delivery on a certain day or time. Delivery to outlying postcode areas may take 1-2 days longer, dependent on your location.
