Ask Gerry

My delphinium flowers are currently dying off and small green shoots are coming out of the fading flowers. It isn't the most attractive look but I am unsure whether it needs to be left alone or cut back, should i be expecting more flowers?

I've collected some seed from geranium/cranesbill plants - how would you recommend I go about getting plants from these: should I sow them now in trays/pods and leave them outside; should I germinate them indoors on a sill; should I hold off and sow them next spring.

A recently purchased gentian has some white flowers, is this unusual?

there is something eating my seedlings in the green house can you tell me what it might be,and how to control it

Where can I buy willow obelisk?

I planted several hanging baskets with Surfinas and Petunias. The plants were all growing well but in one basket plants suddenly started to die off one after the other. I replaced some of the dead plants but after a few weeks the replacements began to die off too. All other baskets seem to be doing OK. Could it be some sort of disease confined to one basket and if so in there anything I can use to treat the other baskets if the plants in these start to die?

I have planted these Heucheras in 3s and it seems that one or two in each group fade away to one or two tiny leaves. Soil is well drained and limey. Have recently fed the garden with good compost. What else can I do to revive them?

I've just noticed that a healthy calibrachoa I have in a window box is quite limp and wilted. The culprit is probably the white fly I noticed at the base of the plant. I'm wondering what's the best way to get rid of these pests and will the poor plant come back to itself again. Regards

We have put a pond in our garden. I want to plant primulas around the pond ,do i need to dig out the soil and line with polythene or just plant them around the pond?

Is this an indoor or outdoor plant and what conditions does it like. I have one in a pot indoors and once it finished flowering I didn't know what to do with it. Can I plant it out ?.

Very excited that I've just dug up 4 old tree stumps and removed all old roots in my front garden. I'm putting down some new mixed compost now today. What can I plant at this time of year in terms of flowers or fruits/ veg? and if i want roses when can I do that. I want to get the most out of the space3m x 1m but the garden itself is about 9mx5m.

Hi Gerry - I have panseys, alyssum and dwarf sunflowers growing in pots and they are suffering with purple leaves and are generally unhealthy looking. Same thing with window boxes: instead of full healthy growth I have scraggly plants with purpling leaves. Erin Premium Compost with added John Innes used in all cases. Watering every 2-3 days. All in full sun. Any ideas?

Searching for phlomis russelliana seeds,with no luck,would you know where i can get them from?

I have 2 wonderful pots filled with purple and white petunias. They are growing rapidly and over taking the small shrub I planted in the middle, which I dont miond for now as they look amazing. Whilst I can prun back now - how do I prepare them at the end of the summer when flowering has ceased for the winter? Do i cut back to the base?

I was just wondering if you would be able to identify the plant in the photo attachment. It has been around for years but I could never find out a name for it. At the start of spring it flowers with pink and purple flowers. During the rest of the year the green leaves are speckled white
