Should i put in support’s for asparagus plant’s i just planted i think they around 2 years old, they look like they need some thing… thanks………Also what’s the proper temperature for glass house when sowing tomatoes ,chilli and peppers.. Should i used miracle grow or go for somthing more organic like nettle feed when feeding.
Tomatoes, chillis and peppers need a temperature of about 20 degrees Celsius to sprout and this can be done indoors in March or later in a greenhouse, or by using a small propagator or heat mat.
The temperature can be lower once they have germinated and usually an unheated greenhouse is okay, but you might need to cover on frosty nights in spring, or have a frost protection heater if sowing is done in March.
Miracelgrow is much richer than nettle feed, which is mostly nitrogen.
For general use, a granular fertilizer provides higher levels of nutrients. This can be done also by organic manures over a longer period of time.
