The veg fed with Baby Bio® are romping ahead

The Baby Bio® Big Boost Challenge involves taking two identical plants. I’ve fed one with Baby Bio® Outdoor and not fed the other. I have chosen to focus on vegetables, and have done the challenge with beans, courgettes, tomatoes, mangetout and chillies.

Fertilising your plants isn’t difficult – it just means adding a liquid fertiliser such as Baby Bio® Outdoor to your regular watering routine every 14 days. However, do be careful not to get water with fertiliser on leaves – make sure that you water the soil beneath the leaves instead.


I did the test with two groups of courgettes. Two ‘Courgettes Romanesco’ were grown from seed and planted in the vegetable bed. Another two were planted in pots. One of each group was fed fortnightly with Baby Bio® Outdoor liquid feed.

The Baby Bio® Outdoor-fed plants produced courgettes to harvest about five days earlier than the non-Baby Bio® Outdoor.

I have harvested 16 courgettes from the two Baby Bio® Outdoor-fed plants and eight from the two that weren’t fed.

We also had a great deal of rain, and at one point, both the courgettes in pots looked very mouldy and manky. I thought they were both on their way out, but both have perked up. The Baby Bio® Outdoor-fed one perked up sooner and has started giving me courgettes again.

The courgette plant that hasn’t been fed hasn’t produced any more courgettes at all. I am now going to feed both plants to see if the plant that hasn’t been fed will start producing courgettes if it is fed from now.

Tomatoes and chillies

It’s too early to say. Plants are growing and look healthy. They have only been planted out for two weeks.

Runner beans

Both Baby Bio® Outdoor and non-Baby Bio® Outdoor bean plants are growing well. I have five red flowers on the non Baby Bio® Outdoor and fourteen flowers on the plant fed with Baby Bio® Outdoor.


I grew these in my mini polytunnel which has turned out to be far too small for them. They are so hopelessly entangled with each other and with the self-seeded nasturtiums that are allowed to roam freely. I’m afraid I have failed in maintaining proper test conditions, but I have eaten a lot of mangetout, so something must be working.
