Food for Lilac Flowers


According to the University of Illinois Extension, the ideal growing conditions for the common lilac, also known as Syringa vulgaris, may be found in plant hardiness zones 3 through 7 of the United States Department of Agriculture. The Excel lilac (Syringa x hyacinthiflora ‘Excel’), for example, can thrive in USDA zones 3 through 9 as long as it is given the appropriate amount of care and the appropriate lilac food. This is one of the few lilacs that has been created specifically for areas that are warmer.

Feeding your lilacs is an act of love that encourages their development and the creation of flowers; nevertheless, much like a mother who is overprotective, giving them an excessive amount of a good thing negates the point of doing so. In point of fact, if you overfeed your lilacs, they may produce a lot of luxuriant foliage but very few or no blooms at all.

Basic Lilac Requirements

Enhancing lilac blooming with either organic or nursery-bought material gives your house the nostalgic aroma of a sachet that Grandma used to make for you. You may give your lilacs a head start by planting them in soil that is rich in humus and has adequate drainage. The plant needs a minimum of six hours of sunshine every day in order to maintain good development and produce the most flowers.

According to the Mississippi State University Extension, lilacs do best when planted in soil with a pH level that ranges from 6.0 to 7.5. If the pH of your soil is on the acidic side, you should work copious quantities of compost into the planting site before you begin planting. You may discover how to properly care for your lilacs by getting the soil tested at the county extension office in your area or at a commercial nursery. The results of the soil test will tell you the pH level of the soil.

About Lilac Fertilizers

There is a wide range of variation in the proportions of nitrogen, phosphorous, and potassium found in commercial fertilisers. According to the Washington State University Spokane County Extension, lilacs perform best when fertilised with a mixture that is either 5-10-5, 5-10-10, 10-10-10, or 20-20-20. You should have a soil test done to figure out the specific kind of fertiliser that will perform the best in your region.

When the lilacs are in their second year, you should start feeding them. Apply fertiliser by broadcasting or sprinkling it directly on the soil at the base of the plants in the early spring, before new growth develops. After the temperatures have begun to increase, often in the late spring or early summer, apply a slow-release or organic fertiliser.

Organic Lilac Food

The gradual release of nutrients that organic fertilisers provide makes them preferable from an environmental perspective. You may make your own organic fertiliser by putting slow-acting ingredients like bone meal, fish emulsion, compost, or manure in the mix.

Even while grass clippings and used coffee grounds are rich in nitrogen, you should only add a little amount of each to your compost. The soil may benefit from the potassium that is provided by banana peels.

Pruning and Deadheading

Lilacs need regular pruning in order to produce an abundant number of flowers. You may remove the faded blossoms from your plants by simply taking them off when they reach that stage. According to the Cornell University Nassau County Cooperative Extension, you should not wait more than a week to ten days after the petals have withered before doing this kind of trimming, which is known as “deadheading.” Your deadheading efforts will assist your lilacs in refocusing their resources on the production of blooms for the next year rather than on the development of seed heads for the current year.

Just after the lilacs finish flowering, you should prune them to manage their height. Waiting until the autumn or winter might result in a reduction in blooming throughout the spring.

Mulching Your Lilacs

Mulch assists with soil water retention and weed control. If you want the greatest results, spread two to three inches of organic mulch, such as peat moss or wood chips, around the base of your lilacs. However, you should avoid coming into touch with the stems that are located at the base of the plants.

When mulching, very gently water the area since excessive watering might encourage the growth of illnesses. Maintain a consistent level of moisture in the soil surrounding your lilacs. If the leaves get yellow, it’s possible that there is too much water being added.
