Growing beautiful roses requires providing them with the right nutrients and care While you can buy commercial rose fertilizers, homemade options are inexpensive, safe and work just as well, if not better Homemade fertilizers made from kitchen scraps and garden waste feed roses naturally without the use of synthetic chemicals. They enrich the soil, improve texture and provide a slow, steady release of nutrients for optimal growth and prolific blooms.
Here are 10 easy-to-find ingredients that can be used to make fertilizers that will always work to grow the best roses:
Used Coffee Grounds
Coffee grounds are a gardeners’ favorite for acid-loving plants like roses. The grounds have a near perfect pH of around 6.5. When mixed into soil they help lower pH, increase acidity and boost microbial activity. Acidic soil is ideal for roses to uptake nutrients efficiently.
Coffee grounds also contain nitrogen, potassium and other trace elements like copper and magnesium. They lighten heavy clay soils and improve drainage.
Used coffee grounds can be spread around established rose bushes. For every handful, mix it into the top few inches of soil. When you plant something new, fill the hole with 1 part damp grounds and 2 parts soil.

Crushed Eggshells
Eggshells are one of the best ways for plants to get calcium. Calcium is vital for cell wall development and structure. It makes plants more resistant to diseases and insect attacks. When the fruit and leaves grow, having enough calcium keeps them from getting black spots and makes their tissues stronger.
Thoroughly rinse eggshells and let them dry. Crush into a powder before adding to soil or compost. The smaller the pieces, the quicker calcium will be released as the shells break down.
For new plants, put 1/4 cup of crushed shells in the hole and mix them well. Every two months, sprinkle crushed shells around the base of established plants to feed them.

Banana Peels
Banana peels are rich in potassium, as well as other minerals like magnesium, sulfur and phosphorus. Potassium encourages blooming and enhances the rose’s perfume. It also helps plants survive harsh weather and makes them more disease resistant.
Chop peels from overripe bananas into small pieces. Bury pieces 2-3 inches deep in the soil around rose bushes or add chopped peels to compost. For new plantings, bury 2-3 peels just beneath the root ball.

Epsom Salt
Epsom salt contains magnesium which plays a key role in photosynthesis, nitrogen absorption, and the production of essential oils that give roses their heavenly fragrance. Magnesium deficiency causes yellowing between veins and poor flowering.
Dissolve 1 tablespoon Epsom salt in 1 gallon of water. Pour this solution around the base of rose bushes every 2-3 weeks. For new plantings, mix 2 tablespoons per hole and water in well after planting.

Fish Emulsion
Used tea leaves are another kitchen staple that can be repurposed as an organic rose fertilizer. The tannins in tea acidify soil while providing small amounts of nitrogen. Break open tea bags and sprinkle the dried leaves around rose bushes. Or brew a strong batch of tea, let it cool and use it to water plants. Add used leaves to compost to enrich it further.

Seaweed Fertilizer
Seaweed is rich in micronutrients like iron, magnesium, zinc and manganese that promote healthy growth. It contains plant growth hormones that boost flowering and fruiting. Seaweed also helps plants withstand drought, frost and other environmental stress.
Buy liquid seaweed fertilizer or make your own by fermenting seaweed – simply pack chopped seaweed into a bucket of water for 4-6 weeks. Use either to drench soil around roses every 2-4 weeks during the growing season.

Compost Tea
Compost tea provides a mega boost of nutrients, microbes and beneficial fungi to enhance soil health and plant immunity. Place a few shovelfuls of finished compost into a burlap sack and steep in a bucket of non-chlorinated water for 3-7 days. Stir and squeeze the bag daily to aerate and extract nutrients. Filter, dilute and apply the compost tea as a soil drench or foliar spray.

Apple Cider Vinegar
The acetic acid in apple cider vinegar controls fungal diseases like black spot, powdery mildew and downy mildew on roses.
Mix 3 tablespoons vinegar in 1 gallon of water. Transfer to a spray bottle and mist tops and bottoms of leaves and stems of infected plants. Repeat every 7-10 days as a preventative. The solution will also repel aphids.

Milk Spray
The calcium in milk strengthens cell walls and prevents black spot infestation. Milk also contains beneficial bacteria that prevent pathogens from attacking roses.
Make a spray by mixing 1 part milk with 9 parts water. Add a few drops of dish soap and spray on leaves, stems and buds every 10-14 days. The caseins and whey proteins in milk also give the leaves a glossy shine!

Dish Soap
Dish soap can be used occasionally (no more than once a month) as a safe insecticide to control aphids, spider mites, thrips, whiteflies and other pests on roses. It works by dissolving the waxy coating on insect bodies, causing dehydration and death.
Mix 2 teaspoons mild liquid soap with 1 quart water. Transfer to a spray bottle and mist leaves, stems and buds thoroughly. Try this only as a last resort if infestations are severe.

Along with these homemade fertilizers, roses need adequate water, full sun, pruning and protection from diseases and pests. By feeding them homemade plant food made from everyday kitchen ingredients, you’ll soon have the most magnificent roses that rival any commercial garden!
ORGANIC ROSE FERTILIZERS YOU CAN FIND RIGHT INSIDE YOUR KITCHEN
Tea leaves are full of naturally occurring tannins. Tannins are acidic in nature and when added to the soil makes it acidic in nature as well. This is exactly what the roses need as they thrive exceedingly well in acidic soil. Tea leaves also contain small amounts of nitrogen, which help in plant growth.
So if you’re a tea drinker, don’t discard those tea bags yet. Just collect and dump them in your compost and apply the compost as a top dressing. Or soak the used teabags in water for a few hours and water the plants with it. Or you can simply remove the spent tea leaves from the bags and spread it on the top soil. Just remember though, that tea leaves by themselves are not a full rose food substitute.
Egg shells are a great source of calcium. Calcium helps to strengthen plant cells and block pathogens from entering the plant body. Calcium also helps strengthen the roots of plants allowing them to absorb more nutrients from the soil. Besides nitrogen and potassium, roses require large amounts of calcium to grow well.
Eggshells don’t break down quickly when they’re whole, so it’s best to break them up into small pieces and mix them into soil or compost. Before you do that though, make sure to wash and dry them thoroughly. Otherwise pathogens from the eggs might get added to the soil causing more diseases.
Ripe banana peels are rich in potassium and therefore a great fertilizer for roses. The cool thing about banana peels is that they break down really quickly, giving plants a lot of potassium. Potassium boosts the immune system of plants and protects against disease and insect damage. It also helps the plant survive difficult climatic conditions such as drought and frost. If your notice weak stems, poorly developed buds or yellow leaves with browning edges, your rose plants are telling you they need a dose of good old potassium.
Add two or three banana peels to the soil when you only plant roses to help them grow faster. You can drop a chopped banana peel in the planting hole before placing the plant in. The peel can also be added with the compost to improve the richness of the soil. If you have a plant that is already well established, you can simply drop a banana peel or chopped peel in the soil next to the plant.
Here is a quick homemade food for roses.
WATER FROM BOILING VEGETABLES
Water that you use for cooking your vegetables are also good sources of minerals and nutrients. Don’t throw them away if you’re not using them in your meals. Cool the water and then water your rose plants with it. Just remember that you cannot reuse the water if it contains salt in it.
The humble baking soda in your kitchen also finds good use in the rose garden. It is used to treat plants infected by black spots and powdery mildew.
