Q – How can I grow amazing strawberries on a sandy soil?
Bunny – Add organic waste/green waste to hold the moisture. I’ve just started growing Malwina which is a darker strawberry
Bob – I grow most of my strawberries in hanging buckets to protect them from pests and it’s easier to refresh the soil every couple of years
Q – I meant to ask about gooseberries…
Bob – Gooseberries need moisture and air ventilation. Maybe some wood ash.
Q – We have a 6ft (1.8m) Camellia which is flowering in lots of different colours. Why?
Bob – This could be a graft-chimaera. There’s a thing called Laburnocytisus adamii, from France, and they would graft Cytisus onto a Laburnum rootstock and they would mix together on the plant.
James – It could be viral but I would lean towards graft-chimaera too.
Q – Can the panel give reasons why my snowdrop bulbs under a large walnut tree keep appearing above the surface of the soil?
Bob – Walnut leaves are hostile and so the soil might be unsuitable for the bulbs.
James – It could be congestion from below from the tree roots. Crocosmia (which are related) will start to come above ground when there’s competition for space.
Q – Is it ok to use collected rainwater on seedlings?
Bob – Damping off disease can damage seedlings but that’s normally if they’ve been in a water butt for a long time. To be safe, use boiled tap water.
Bunny – Temperature makes a big difference – so make sure it’s not too cold. Keep it covered and use it a lot.
Q – Can you recommend plants to hide an unsightly outlet pipe?
Bob – Try a variegated Holly.
Bunny – Skimmia japonica ‘Pabella’. A few Cosmos around the base.
James - Mahonia. Pittosporum tobira.
Q – We have a 6-year-old lemon that is producing fleshless fruit; why?
Bob – I think it’s got too dry and it is withdrawing moisture from the fruits.
James – Hostas, Aeoniums.
Q – When should I prepare and plant a new asparagus bed?
Bunny – It takes three years to get going but then they can go on for many years
James – Buy them early and plant out in February/March time
Bob – You can sow seed in pots now and then plant out in Autumn
Q – Can you recommend plants for a dinosaur-themed garden?
Bunny – Gunnera. Rheum. Tree ferns. Moss.
James – Dicksonia. Equisetum (the non-natives). Azolla water ferns. Tetrapanax papyrifer ‘Rex’.
