Gravel paths in veg plot

Posted: 05/03/2017 at 11:44

I'd do both, a quick spray (especially along the edges) with roundup and cover with weed membrane.  To protect the membrane from being punctured by the sharp edges of the gravel I'd recommend a layer of woven landscaping fabric on top of the membrane, too.

Are these climbers dead?

Posted: 05/03/2017 at 11:34

I think the 'controversial' climber (ie 'not boston ivy') with the red leaves and tendrils is an ornamental grapevine.  That won't show signs of life until quite late, probably May.

Agapanthus have proven to be absolute thugs in my borders - huge spreading roots which prevented anything nearby from growing.  That's why I dug them all up and now only grow them in pots - not because they like it! 

As for the depletion thing, the microbes which break down woody matter require nitrogen to do so and will take it from the soil.  However, unless you mix (say) sawdust well into the soil, they can only take it from the top few mm so nothing to worry about when mulching as that is always left on the surface (else it wouldn't actually be a mulch!)  Judging by the amount of nitrates in our food and water, a bit of depletion might not be a bad thing..

Lots of gardening 'lore' is probably just misinterpretation.  If someone find a method of consistently growing a particular plant well, they will do it again and tell others.  Take a (made-up) example that adding crushed egg shells to the bottom of a hole before planting hostas makes them grow better.  They do an experiment with 100 'eggshelled' hostas planted side by side with 100 'un-eggshelled'.  The differences are clear and repeatable.  One might assume "it works because it increases the calcium levels" when, in fact, it may simply be because it improves drainage.  After a few rounds of 'chinese whispers', it becomes a 'fact' that hostas need extra calcium. 

Potatoes fertiliser

Posted: 03/03/2017 at 20:37

The NPK ratios of potato fertiliser are very similar to those for rose fertiliser and are roughly 1:1:1.5.  In reality, the ratios do not matter much, but leafy veg do use more N while roots take more P and flowers/fruit use more K.  I'd use it as a general fertiliser but provide some extra Nitrogen for brassicas and other leafy veg.  Don't bother fertilising carrots though as they don't need much of anything.

Raspberries (summer) which didn't do anything last year - leave them be or start again?

Posted: 02/03/2017 at 18:53

Keep the ones which start growing leaves but you may as well pull the other ones up and replace them as they are almost certainly dead.  Bare-root raspberries can be a bit hit-and miss but those which survive will rapidly spread once they are established.  The dead ones will likely pull out easily whereas any which have grown roots will not, so a gentle pull is an easy way to tell which are alive and which aren't.  If you replace any, consider getting 'Polka', an autumn fruiting type which many on the forum grow and we always have super crops.  Keep summer and autumn fuiting types in different areas though, so if you do go for it you could move the live ones you have to the same area and use the other for the autumn fruiting ones.  Polka are easy to prune - just cut the lot down to the ground in Feb each year.  For summer fruiting types, you cut down only the canes which have fruited after harvesting them and leave the new canes which have grown from the base alone, as those will provide next year's fruit.

Any idea what these are?

Agree fidget for the first 2 pics.  Green 3-leaved things in the bottom photo look like wild strawberries which can be a nuisance.

Tall single stem plant identification

Posted: 26/02/2017 at 21:19

I agree, a tree peony.  I have 4 different ones and the buds on one of those look very much like the photos.  Hopefully, the new stems from the base will help it bush out a bit in the future.  Be careful when weeding around it as it is all too easy to accidentally knock the buds off at this time of the year.

You might be lucky Aym but expect a long wait of at least 5 to 7 years.  You never know though, you might get a stunner!  That's the beauty of growing things from seed.
