Fertilize aubergines organically on the day of planting
Time is short for an aubergine to bloom profusely and bear ripe fruit in the Central European climate. Provide the exotic egg tree with a well-stocked nutrient buffet on the day of planting. With this organic starter fertilization you do it right:
- bed/greenhouse: Work in 3 to 5 liters of mature compost per m² of planting area
- bucket: enrich peat-free potting soil to 1/3 with sieved compost soil
Before you water an aubergine after planting, sprinkle the root disc thinly with horn shavings (€32.93) or horn meal.
Make your own organic fertilizer and dose it correctly
The right fertilizer for aubergines takes effect quickly and is free of chemical and mineral additives. Nettle manure from our own production fulfills both criteria with flying colours, strengthens the immune system and improves the taste of the eggplant. Recipe and dosage are so simple:
Making liquid fertilizer for eggplants
- Fill the vat with 1000 grams of nettle leaves
- Fill in 10 liters of rainwater
- Put the lid on or cover the jar with jute
- Place in a sunny location for 10 to 14 days
- Stir daily
The fermentation process can be recognized by rising air bubbles and an intense smell. If no more bubbles appear when stirring, the nettle liquid manure is ready. Pour the broth through a sieve. You can dispose of the plant remains in the compost.
Eggplant fertilize with nettle manure
The fermented plant manure is too highly concentrated to be used as a liquid fertilizer. Dilute the liquid manure concentrate by adding ten liters of collected rainwater to one liter of nettle stock. The easiest way to administer the liquid organic fertilizer is with a watering can. At intervals of 10 to 14 days, pour nettle manure over the root slice of an aubergine. It is important to note that the plant leaves are not wetted with the liquid.
tips
An aubergine should use its strength and not invest in sterile side shoots. Every time you fertilize, please keep an eye out for small shoots that sprout from the leaf axils. These are useless branches that are not welcome on tomatoes either. Simply snap off the stinging shoots with two fingers.
