Why do beginners often fail when growing roses?
The editor explains the related green plant topics of why beginners often fail when growing roses, offering some very useful tips and knowledge, it's recommended to save this for future reference!
Recently, many friends looking to buy rose seedlings often ask this question:
I'm new to growing roses, is this variety easy to care for? Can it survive? The ones I grew before died with black stems.
Actually, the rose varieties in the store are all classic, hardy ones with strong disease resistance and vitality, so they are quite easy to care for. Sometimes, the reason why新手 gardeners fail to keep rose plants alive is mainly due to their own cultivation methods, not because of the seedlings or rose varieties.
For instance:
Yesterday, a friend asked about their rose plant, which became deformed after repotting, and the old leaves turned yellow. They didn't know the reason.
After looking at the photo they sent, it was clearly a case of fertilizer burn. After detailed inquiry, it turned out that this friend had put fermented chicken manure at the bottom of the pot during repotting, and it was correctly separated with soil, so the issue with the bottom fertilizer was basically ruled out.
Then they mentioned that they used a lot of "Flower多多..."
Pause, only one week after repotting and already using "Flower多多." Can you see where the problem lies now? It's strictly forbidden to use fast-acting fertilizers right after repotting, as it's very prone to causing fertilizer burn.
Actually, quite a few friends make the same mistake. Today, I'm lazy to summarize, but here are a few fatal mistakes that beginners often make when growing roses.
1. Using fast-acting fertilizers immediately after repotting
Why do beginners often fail when growing roses?
Using fast-acting fertilizers immediately after repotting, just like the friend mentioned above, and some even use fast-acting compound fertilizers as the bottom fertilizer, directly adding fast-acting compound fertilizers during repotting. This approach is very fatal for roses.
Only slow-release fertilizers or fermented organic fertilizers can be used as bottom fertilizers!
2. Using a large pot for small seedlings
Some friends don't know what size pot is suitable for what size seedling and often plant small rose seedlings in large pots, resulting in a situation where the pot is too large for the plant. This easily causes the potting soil to accumulate water, leading directly to root rot in the roses.
A large pot holds more soil and retains more water, and small rose seedlings can't consume that much water. If the potting soil's aeration is not good enough or the water is not properly controlled, it's very easy to cause waterlogging and root rot, resulting in the rose plant wilting, yellowing leaves, leaf dropping, and black stems.
3. Repeated watering
