Over fertilised lawn urgent help. I am panicking

hhosany

Hi

I need some advice. After spending two days gardening and planting I thought it would be a good idea to buy some fertiliser for the lawn. so I bought some Westland fertiliser from a garden store. I bought a box and was advised to spread with hand and should get some green lawn and healthier flowers and grass. I have spread the fertilisers this evening and was very heavy not reading the instructions. 

Needless to say I have over fertilised the lawn and plants and now panicking. Please can anybody help as we have just spent lots of money on flowers and soil and very scared everything will die.

thank you in advice....

Did you water it in? If it's for grass only I doubt it'll be very good for your plants unless it was a feed only. You might get away with that if you water everything really heavily every day for a week to dilute it a bit.   

If it was weed and feed - you'd better get the hose out and cross your fingers. Anything small, weak and vulnerable is unlikely to survive that, even with plenty of water to dilute it. The grass will survive though.

Give everything a good soaking with the hose - a really good soak - like heavy rain for an hour or more. We'll cross our fingers for you.

Next time use garden canes to mark out a square metre so you know how big that is. Get a paper cup and measure using the kitchen scales the correct dose. Mark a line on the paper cup and use that for every square meter. And always read the labels in future. You may have learned a hard lesson. fingers crossed a good watering will help.

Thank I think I will dig up some of the valuable plants and smaller weaker plants. Then soak for a week. Thank you I will keep you updated with progress. 

Thank you you for the quick replies

Don't soak for a week!  It doesn't do most plants any good to have their roots in water - you'll  do more harm than good and the roots will rot.  They need oxygen.  Just give them a really good water as we said.  

Unless you've put the fertilizer on my the shovel-full you won't have done that much harm I'm sure.  

Although the box gives emounts, it's not an exact science ... there is a little leeway.
