Growing on perennials from plant plugs

Question

I am new to gardening and am currently trying to grow on perennial plant plugs in my conservatory prior to planting out. The conservatory gets full sun for most of the morning and good light throughout the day. I have tried to ensure that it doesn’t get too hot but despite this some of the plants are growing too leggy particularly the verbenas. Is there anything I can do to prevent this?

Thank you

Answer 1

Leggy seedlings are generally due to lack of light. To much heat will cause wilting and even kill the small plants.
It is a balance keeping them warm but not to warm. Adding some moving air can help cool down the plants.
Using a small fan to circulate the air can help .

Here are some links that will help you with care of seedlings.
