How to grow giant roses into old piles

The height of giant roses is 1-2 meters. The season is very important for successful transplantation. The temperature is not high in spring and autumn, and the air humidity is high. Secondly, when transplanting, you must pay attention to pruning the branches, cut off diseased branches and some redundant branches, so as not to compete with the main branches for nutrients and nutrition during the transplantation process. During the transplantation process, pay attention to protecting the roots and try to transplant with soil.

To grow giant roses, you need to choose fertile, slightly acidic sandy loam and replace the potting soil every year. If you want it to bloom, you need at least 6 hours of light a day. The suitable temperature is 18-28℃, and the maximum temperature should not be higher than 32℃. Water it when the soil is dry and water it thoroughly. Fertilize frequently during the growing season, and apply light fertilizer water once every 10 days.

Generally speaking, giant roses need to undergo four prunings in a year. The first pruning is mainly to remove withered flowers to avoid nutrient waste. The second pruning is mainly to prune overgrown branches and withered flowers, also to avoid unnecessary nutrient consumption.

The third pruning is to make the plant more beautiful, focusing on pruning dense, overlapping and crossed branches. The fourth pruning is to prepare for wintering, and usually all branches that do not grow well need to be pruned off.

They are also not resistant to falling and will break if they fall.

If giant roses are watered too much, the roots will not absorb oxygen and will rot. Stop watering immediately and place them in a ventilated place to increase water evaporation.
