Q.
My vegetables are going to seed very quickly which implies that my soil may be too rich. How do I remedy this please?

- This is called 'bolting', plants go to seed for various reasons.
- The main reason is stress which could be caused by a sudden change in temperature from hot to cold or excessive heat, plants think it is time to reproduce and so go to seed.
- Other reasons are planting seedlings that have been in the punnet or pot for too long and are root bound when they are planted out.
- Not planting seasonally appropriate varieties, for example planting winter lettuce in summer.
- Irregular watering and water stress can cause bolting, especially if plants have dried out over a period of time and change in day length can cause plants to bolt.
- Make sure your seedlings are not held too long before planting so that they don't become root bound.
- Plant seasonally appropriate varieties, ensure plants are consistently watered during the growing season and regularly fed to keep them actively growing.
- Dig in plenty of organic matter such as compost and sheep pellets to the soil before planting, this helps with moisture retention, improves soil structure and is a source of nutrients for plants.
- Feed with a balanced fertiliser so plants are getting all of the nutrients they require, weekly applications of Tui Superfood Vegetable & Herb liquid fertiliser are beneficial and promotes all round growth.
- Debco Saturaid applied to the soil or dug in at the time of planting helps retain soil moisture, it helps channel water to the roots and retains soil moisture.
- It is a bit difficult to do anything about the season and temperature change, make sure the varieties being grown are appropriate for the season.

Why are my vegetables going to seed quickly? Comments
Why are my vege plants going to seed? I water and feed, do not let them dry out, have tried doing my own seeds plus buying plants, but get the same result.

Hi Betty, plants bolt or go to seed for various reasons, it could be the soil they are growing in, always add extra organic compost when planting new crops. Make sure the seedlings are not root bound or held in their container for too long before planting out. Sudden changes in temperature are also a factor, when plants are stressed it is a signal for the plant to reproduce itself and so they go to seed. Make sure the seed being grown is appropriate for the season, that is, don't try growing crops that enjoy cooler conditions in summer and vice versa. Even though you are watering regularly, it is important that the soil retains moisture, add plenty of organic matter and also consider adding Debco Saturaid at the time of planting to help retain soil moisture. When replanting crops always add more fertiliser at the time of planting, it could be sheep pellets, Blood and Bone or Tui Vegetable Food to replenish the nutrients. Make sure the vegetable garden gets at least 6 hours of sunshine a day to get the best from your vegetables.
