When, with what and how is Syringa fertilized?

Do you even have to fertilize planted lilacs?

Basically, you don't “have to” your garden lavender fertilize. However, if this has been in its location for a few years and you may already have one decreasing floral splendor have wondered, then the cause could be a lack of essential nutrients. If the lilac suffers from a lack of nutrients, it no longer has enough strength to develop the flower - and at some point it may no longer bloom at all. Lilacs in locations with very poor soils also benefit from a fertilizer application.

When is the best fertilization?

Both planted and potted lilacs are fertilized for the first time in early spring, shortly before budding. Depending on Condition of the soil this can be enough if the earth is rather rich in nutrients. If, on the other hand, the subsoil is rather sandy and poor, you can take care of the lilac again in June.

Since lilacs (with the exception of Preston lilacs) prefer to grow in calcareous soil, the pH of the soil should be between 5.5 and 7. If it is lower, fertilize the plant with a calcareous fertilizer once a year. Carefully work this into the top soil layer.

First fertilization when planting

The lilac receives its first fertilization when it is planted. Here you mix the excavated material with plenty of compost and a generous handful Horn shavings.(€ 32.93 at Amazon *) The natural fertilizer acts as a stimulus for healthy growth and provides the plant with all the nutrients it needs for successful growth.

Fertilize the planted lilacs properly

Whether and how you should fertilize your planted lilacs depends on the specific soil conditions in your garden. The leaner it is, the more often it has to be fertilized. If possible, use an organic, slow-acting fertilizer with high levels of potassium and phosphorus. It should only contain a little nitrogen, because this acts as a growth booster with the result that the lilac grows very quickly and forms many shoots - but no flowers.

Which fertilizers are suitable for supplying the lilac?

Organic fertilizers are completely sufficient for the supply of nutrients and also have the advantage that they do not seep into the groundwater. The following are particularly suitable for lilacs:

• ripe compost
• Horn shavings(€ 32.93 at Amazon *) or horn meal
• Manure (preferably Horse manure, but no poultry manure! This is very nitrogenous.)
• self-made brew of nettles and field horsetail

Alternatively, you can also supply the lilac with blue grain (be careful, only use a little!) Or a commercially available fertilizer for flowering trees.
