Cold frames and greenhouses

Posted: 21/10/2013 at 12:59

I suppose the difference between a coldframe and greenhouse is that you can walk into a greenhouse. There is no temperature difference between a coldframe and cold greenhouse unless you use a heater in a greenhouse to keep a certain temperature. So you generally use a coldrame for hardy plants or plants that are hardy due to being kept dry - Agave for example.

I would say a bigger killer than cold is grey mould caused by inefficient ventallation in both coldframes and greenhouses, especially on seedlings. Any sunny day, open the doors to ventillate both.

I started with coldrames and moved up into greenhouses and use both - you can use a coldframe inside a greenhouse to add a little more protection.

Succulents advise

Sand actually holds a lot of water - that is why you can build a sandcastle. If you want to try succulents then add about 75% pea gravel 10% sand and rest compost mixed with bark. You also need to build the site up as sand pits tend to be sunken. If you are going to try Cacti or Agave then a roof to stop winter rains and snow is necessary as their hardiness is directly related to how dry their soil is.

Yellowing is a sign of stress - normally lack of water during the summer.

Verdun is 100% correct. Even clumping Bamboo bolt when they feel like it, yes even Fargesia. The worst is P.Nigra which behve for years then send out runners over and underground!

Verdone Extra Liquid Concentrate Lawn Weed Killer is great of clearing Clover. My lawn was quickly being overtaken and now is green and Clover free. I recommend it.

Plants that I can put infront of a conifer hedge

@Verdun, am sure that you know that the bottom of conifers is especially dry and raped of nutrients. Dryopteris will not do well there - they can deal with dry spells but are hardly succulents and they prefer dampish well draining soil.

Ferns prefer filtered sunlight with damp soil - Ferns die more from drying out than anything else. That does not sound like the bottom of a hedge which will be shaded and very dry depending on which face you plant. Soil is also very acidic under a conifer hedge...so unless you can find a Fern variety that like dry soil I would steer you away from them.

Can I repot my Acer now?

Posted: 18/10/2013 at 21:45

I would say wait till Feb. Acers are prone to drowning by overpotting, so doing now as we go into winter is not a good idea.

Debbie, no do not pot up now as that can cause drainage issues by overpotting and the Acer dies. I would leave it until early spring then repot if needed. I would not change the soil needlessly either. They just prefer acidic soil rather than need it, so the GC was kind of right though they did sell you expensive ericaious when it did not really need it.
