If you have lavender in your garden, you will be greeted with its magnificent growth and finely scented purple flowers in summer. The plant can be cultivated in a pot or outdoors. True lavender bears the scientific name Lavandula angustifolia and originally comes from the coastal regions of the Mediterranean. There it grows in almost every garden, but also outdoors on steep slopes. The Mediterranean herb is actually not demanding at all and is used to rather barren soil. However, it needs nutrients to thrive well and healthily. Therefore, you can fertilize the lavender with coffee grounds or with other organic fertilizers. Here, however, you have to be very careful with the amount of fertilizer, because over-fertilizing could make the herb sensitive to frost or cause it to lignify quickly. In the worst case, this can even lead to the extinction of the plant. You can find out everything you need to know about the correct fertilization of lavender from us!

How and when should you fertilize lavender with coffee grounds?
Most hobby gardeners no longer buy the usual fertilizers in flower shops because they are full of chemicals. People prefer natural fertilizers that they make themselves from food at home. These fertilizers are organic and environmentally friendly, so you protect the environment, but also your wallet, because they cost basically nothing. Because of this, coffee grounds have become very popular as a fertilizer for indoor plants and garden flowers. You can also use other household waste products like banana peels and eggshells and make something good for the garden yourself. The next video illustrates this process and gives you more info about homemade organic fertilizers:
There are many vitamins and minerals in the coffee beans, but also in the coffee grounds.
Your lavender plant may like poor soil, but it cannot thrive well without any kind of maintenance. The plant needs nutrients to develop really well and healthily. The Mediterranean herb prefers calcareous soils with a neutral to slightly alkaline pH value, for example between 6.5 and 8. You always have to keep this in mind with lavender. Small amounts of coffee grounds can lower the pH of the soil because the waste product from the coffee maker makes the soil acidic. Therefore, when fertilizing lavender with coffee grounds, you can follow the following well-tested rules:
Small amounts of coffee grounds provide the lavender plant in the pot with the necessary nutrients.
1) Fertilize lavender in the pot with coffee grounds
Fertilize the purple darling in early spring by spreading dry coffee grounds around the plant’s roots. In June or July, repeat this again. This is how you supply the plant with new nutrients. This little fertilizing is enough for the lavender in the pot.
Outdoor lavender should be fertilized in early spring.
2) Fertilize lavender outdoors
If your lavender thrives outdoors, you can fertilize it once in the spring and then again in the fall. However, the second fertilization is not a must. Spread some compost around the root area as well. This is enough and makes the plant more resilient and healthier. This makes it easier for them to hibernate outdoors because they are well supplied with nutrients.
First spread some coffee grounds in the root area, then pour compost over it.
