And you thought greenback was a US dollar bill!
Q: I grow a tomato called Shirley. The number of fruits is wonderful, they look as if they are ripe but are as hard as a rock. BS, Chichester.
A: The problem is greenback and is caused by sudden hot weather and over-use of high potash fertilisers. Water in the late evening. Do not feed with tomato fertiliser but use Maxicrop Complete and the fruits will ripen as they should.
Q: I had a bouquet for my birthday. Part of the arrangement was a kind of silver-haired plant. I would like to know its name and where I can buy it. JM, Fareham.
A: I think it’s isolepis, a hot house plant. If I see any I will let you know.
Update: I wrote about indoor freesias a few weeks ago and how difficult they are to find. Mrs Bennett, of West Leigh, says they are in at Keydell and Stanstead Park and cost £5 for 3 packs. Thank you, I’ve bought some.
Q: Do you think a new lawn is best from rolls of turf or seed? My wife wants an instant effect but I am more interested in best quality in the long term. CB, Bedhampton
A: Rolls of turf are best as the producers use excellent grass seeds of modern species and the
turf is weed-free. For best results buy or hire some scaffold planks. Never walk on newly-laid turf. Keep off it for two weeks.
