It is generally recommended to fertilize before sowing to provide essential nutrients for the seeds to germinate and grow. Fertilizing the soil before sowing can help improve soil fertility, promote healthy plant growth, and increase crop yield. However, it is important to follow the recommended application rates and timings for fertilizers to avoid nutrient imbalances or damage to the seeds. **

I fertilize my plants every 2-4 weeks during the growing season, which is typically spring and summer. I use a balanced liquid fertilizer to provide essential nutrients for healthy growth. During the fall and winter months, I reduce the frequency of fertilizing to once every 6-8 weeks or as needed based on the plant's condition. It's important to follow the specific fertilizing recommendations for each type of plant to avoid over-fertilization. **

Fertilizing bonsai is essential for their health and growth. It is recommended to use a balanced, water-soluble fertilizer specifically designed for bonsai trees. Fertilize your bonsai during the growing season, typically from spring to fall, following the instructions on the fertilizer package. Be sure to dilute the fertilizer to avoid burning the roots, and apply it to the soil surface rather than the foliage. Additionally, it is important to regularly flush the soil with water to prevent salt buildup from the fertilizer. **

To fertilize succulents, it is important to use a balanced, water-soluble fertilizer diluted to half strength. This should be applied during the growing season, typically in the spring and summer months. It is important to avoid over-fertilizing, as this can lead to root burn and damage the plant. Additionally, it is best to apply the fertilizer to damp soil to prevent any potential burning of the roots. **

To fertilize grass, you can use a granular or liquid fertilizer specifically designed for grass. Follow the instructions on the fertilizer package for the correct application rate and method. It's important to water the grass thoroughly after applying the fertilizer to help it penetrate the soil and reach the roots. Additionally, it's best to fertilize grass in the spring and fall when the grass is actively growing. **

We fertilize vegetables to provide them with essential nutrients that may be lacking in the soil. These nutrients, such as nitrogen, phosphorus, and potassium, are necessary for the healthy growth and development of the plants. Fertilizing also helps to improve the overall health and productivity of the vegetable plants, leading to better yields and higher quality produce. Additionally, proper fertilization can help to prevent nutrient deficiencies and ensure that the plants have the resources they need to thrive. **

No, he does not fertilize sterilized soil. Fertilizing sterilized soil would be unnecessary and ineffective, as sterilized soil has been treated to remove all living organisms, including beneficial bacteria and fungi that help plants absorb nutrients. Fertilizing is typically done in non-sterilized soil to provide essential nutrients for plant growth. **

To fertilize rhubarb, you can apply a balanced fertilizer in the early spring before new growth begins. Use a fertilizer with a ratio of 10-10-10 or similar, and apply it around the base of the plant according to the package instructions. Avoid over-fertilizing, as this can lead to excessive leaf growth at the expense of the edible stalks. Additionally, incorporating organic matter such as compost into the soil around the plant can also help provide nutrients for healthy growth. **
