Can this be used as a general plant food, or only for tomatoes? And are there any plants it must not be used on, like roses ? thankyou
speaking about Verve Tomato plant food concentrate....
Fertilisers designed for tomatoes will contain the nutrients that encourage flowering and fruiting so can be used on plants that you want to flower shortly.
It's not a good idea to use them on young plants that are still in early growth, or on foliage plants or leafy vegetables.
thankyou, understand now
I grow a load of pelargoniums in a conservatory ....not really a fav of mine; colour but no form......and I use phostrogen currently. However, I ring the changes, feed not too often but water well to avoid the build up of nitrates.
In the GH I have tomatoes and peppers. Seaweed feed, an occasional phostrogen feed, Epsom salts once or twice, a spray of diluted milk a couple of times and an initial fish blood and bone feed is their regime.
Generally a balanced fertiliser is fine for most plants. Need to be careful with ericaceous plants though.
Used to use specialist feeds in my early (over keen) days to try and produce super plants. However, I i think now under feeding is better than over feeding. Better not to force plants but let them grow slowly and sturdily
Totally agree Verdun, soft lush growth only leads to problems with slugs, snails and fungal infections
Once a week when they are showing flower heads. John mcleod. Especially in pots.
Many of these liquid summer feeds are similar. Phostrogen is still hard to beat. Dont really grow many annuals but it's good to build up foliage initially and then allow them to flower. Once a week is fine.
