Antirrhinum Growing Guide
Open Packaging Immediately on Receipt
· Place the plants somewhere reasonably warm. If you have a greenhouse, around 16-18°C is the best temperature. Alternatively a kitchen windowsill is a suitable place.
· Allow the plants to settle and acclimatize for 2-3 hours.
· Water your plants with clean tap water. The best way to do this is to place them in water for a few minutes and allow them to soak it up. A saucer or dish should suffice, alternatively the opened out transport packaging makes a handy container.
· Transplant your plugs on the day you receive them if you can. Use a good quality , free draining multipurpose compost. 13cm pots (5”) are the best size to use. If you are using old pots, make sure you sterilise them first to remove any pathogens. We find Jeys Fluid to be the best, if you can’t find any, give them a good wash with warm water and soap.
· Fill your pots with compost up to about 1cm below the rim. Don’t compact the compost in the pot. Make a hole in the centre roughly the same size as the plug plant. Handle the plant gently by the leaves or root ball place in the hole, minimising compost compaction below the plug. Try to make sure the surface of the plug is not buried Firm lightly around the plug.
Watering
• The media should be allowed to dry regularly
between watering and never saturated.
• Avoid excessive water stress as this will cause
foliar damage.
• Care must be taken to avoid damaging the root
system when pinching recently transplanted
