Key management points for Chinese roses in March in southern regions.

Key Points for Rose Management in March

Share some small experiences in rose cultivation with key points for March management, let's follow the editor to take a look!

If you want your roses to bloom more and have fewer blind buds in spring, the management in March is crucial. March is the season when new rose buds grow rapidly, and poor management at this time may result in a large number of blind buds and yellow leaves, directly affecting the first batch of spring flowers.

Key Points for Rose Management in March

The temperature differences across regions in March are quite significant, and the growth conditions of roses will also vary greatly, so the management cannot be generalized.

I. Northern Regions

For friends in the north, March is still relatively cold, and the new rose buds are just beginning to sprout, it seems there's nothing much to do. However, it is important to pay attention to the following four things at this time.

1. - Remove Coverings in Time -

In the cold northern regions, roses need to be covered with insulating cloth for winter protection. By March, when the temperature stabilizes above -5 degrees, it's necessary to gradually remove the coverings. If it's done too late, roses may sprout prematurely, which will affect growth.

2. - Pruning and Cleaning the Garden -

If roses were not pruned in winter or if the pruning was not thorough, it can now be supplemented. After pruning, use lime sulfur to spray comprehensively for a garden cleanup, which can greatly reduce the occurrence of diseases and pests in spring.

3. - Repotting and Supplementing Fertilizer -

For roses that need repotting, it is recommended to repot before the buds sprout, replacing the soil and adding a sufficient amount of fermented organic fertilizer to replenish soil fertility. For roses planted in the ground or those not being repotted, if no winter fertilizer was applied, it should be supplemented now.

4. - Supplement Water in Time -

Less water is浇ed in winter, and potted plants with dry soil should be watered thoroughly to replenish moisture. For roses planted in the ground, if the soil is dry, it should also be watered sufficiently.

II. Southern Regions

In Guangdong, Guangxi, and Fujian regions, roses are currently in bloom, and the main management task is to prevent and control diseases and pests, focusing on preventing black spot and red spider mites. It is also important to maintain sufficient fertilizer and water, fertilizing regularly. When the roses finish blooming, branches should be pruned promptly, and the pruning can be a bit heavier to control the plant shape.

III. Eastern and Central Regions

In regions like Zhejiang, roses are now in the rapid growth stage of new buds. If the following points are managed well during this period, the roses will bloom beautifully in spring.

1. - Apply Light Fertilizer Regularly -

New rose buds grow rapidly and require a lot of fertilizer and water. If the fertilizer is not sufficient, many new buds may become blind branches and fail to bloom properly. Therefore, from March to April, it is essential to apply fertilizer frequently and lightly, avoiding heavy fertilization and being careful with scattered fertilizers to prevent fertilizer damage.

Before the rose buds appear, it is recommended to use a balanced general fertilizer with nitrogen, phosphorus, and potassium, applying it every 3-5 days by watering and every 2-3 days by spraying leaves. When small flower buds appear at the top of the branches, switch to phosphorus-potassium fertilizer and apply it every 5 days or so. If the watering frequency is high, a small amount of light fertilizer can be added each time.

2. - Avoid Drought -

New rose branches require a lot of water during rapid growth. Prolonged drought can lead to poor growth and a large number of blind branches.

In spring, you can water a bit more as roses grow vigorously and quickly. As long as there is no waterlogging, the roots will not be suffocated. Water when the surface of the soil becomes dry. Make sure to water thoroughly until a large amount of water comes out from the bottom of the pot. For young plants in large pots, water when the top 2cm of soil is dry.

3. - Prevent Aphids and Diseases -
