You put the fertilizer on top of the pot. As a rule of thumb we use that you give one handful per 10 liters of pot content.
You can also give a slow-acting fertilizer (for example osmocote) that works for 3 months. In that case you only give the fertilizer in May.
No more fertilizer may be applied after August. The plant must then harden off and rest for the winter.
You can repot your bay laurel in summer. The size of the plant determines the moment of repotting.
Remove the old pot and immerse your bay laurel in a bucket of water for 5 minutes.
The diameter of the new pot should be about 5 to 10 cm larger than that of the old pot.
Remember to take a pot with enough holes in the bottom. Excess water should be able to exit the pot easily.
Put a layer of 2 cm pebbles or clay granules on the bottom of the pot. This promotes drainage.
You can use a 'heavy' potting soil. That is, a potting soil in which peat, clay and dried organic fertilizer has been mixed. You do not need to add additional fertilizers. The potting soil contains enough nutrients for the coming period. A recently repotted plant is a bit more fragile than usual. Give the plant some extra attention during the first period.
