Re: getting the soil acid,any suggestions

Pine needles, coffee grounds, leaf litter by making a 1 metre sq cage and collect just leaves a fill and you'll have leaf mould, great stuff for free. Pine needles do not make any significant difference to soil pH; you would need a very large quantity of coffee grounds (the same goes for tea leaves...

Re: getting the soil acid,any suggestions

At Highdown Gardens, on the South Downs at the back of Worthing they have solved the problem by building raised beds 60 - 90 cm high and filling them with imported acid soil - which is probably the most successful log term solution. However these beds are enormous! In correcting chlorosis, which is ...

Re: Plants\tress that like 50% shade

My suggestions is ignore the "problem". Most plants will be quite happy in that situation (unless they are out and out sun lovers such as Cistus). A six foot fence might cast quite a shadow on the ground, but as soon as a plant has grown two or three feet it will be up in the sun anyway.

Re: Huge variation in agave montana seedlings

An experienced UK Agave grower has told me of his experiences with A montana : "that small plants (by that I mean smaller than 40 - 50 cm) are very cold tolerant but have not built up their wet tolerance yet. So kept dry they survive without problems but last winter proved that they rot when faced w...

Re: Radiation Frosts - Definition

Radiation frost is also called hoar frost. Errr . . . nope! Radiation frost is sub-zero temperatures caused by items radiating heat (infra-red electromagnetic radiation) into space (as space is colder than the items, the radiation trasfers from warmer to colder). Hoar frost is ice crystals condensi...

Re: Radiation Frosts - Definition

It is called radiation frost because the plant radiates its heat to the open air, so causing it to become cooler than the surround space, it is this that caused the frost to form on the plant. Radiation frost is also called hoar frost. Covering the plant as Nathan suggests prevents the radidation or...

Re: Cacti ID please

It looks to be an Epiphyllum or other epiphytic cactus. It also looks to be starved of light with those very long thin growths. There are numerous hybrids in addition to the species, giving it a more specific name might be difficult.

Re: Stuck on what to buy with a stricted limit.

Call be biased, but I grow around 150 different Hemerocallis (Daylilies)

Here are some of the brightest reds I grow, all large flowers some up to around 30cm across. They really do glow in the garden and flower over a long period.

Re: Over wintering plants

They look like they are happy there Mo. I think the secret is cool, bright with airflow. I'm surprised that you use grow lights for overwintering cacti. While they are dormant, ie not growing, they do not need light. For a few years after moving to a new garden and having not yet set up a greenhous...

Re: Leaf curl on a Bird of paradise seedling

I've noticed both Strelitzia reginae and its big brother S nicolai have a tendency to curl their eaves, especially as seedlings, but to no ill effects - so I don't think it is anything to worry about (my S nicolai are now 2m tall and one of the S reginae has reached flowering size.)

Re: Has anybody over wintered canna's indoors

I grew a couple of Canna indoors through last winter, they did grow a little leggy but not so much that the stems needed support. I also sowed some Canna seed last autumn which germinated with a few days; I grew the seedlings on indoors overwinter with no problems, and planted them out in the spring...

Re: Chopping up Opuntia Pads

A large Opuntia pad should keep until the spring with no problem. I kept a bucket full or pads from October last year 'til this spring before potting them up, they rooted almost immediately. They were kept in the frost free greenhouse, but anywhere cool and dry would be fine, even somewhere like the...

Re: Arundo Donax

I would not describe it as invasive, but if it likes where it is growing it will very quickly make a sizeable clump. Even planted in the driest part of my very dry garden, within a couple of years it had spread to 120cm across. I've since dug it up it and after several years kept in a buck of water ...
