Frequently Asked Questions
How do I look after my hostas?
Hostas are hardy perennial woodland plants that
love shady, moist conditions so:
- give them plenty of shelter: preferably from trees
but walls and fences can to the job too
- don't let them dry out BUT don't let them become water-logged: stand pots in a dish or tray and water from there. This allows the plant to take all it needs and takes the guess work out of watering.
There are a handful of cultivars that can withstand full sun but we recommend you provide good levels of shade for the very best colour.
Cultivars with white in the leaf are especially prone to scorching and can be damaged by drying warm winds as well as direct sunlight. Scorching reduces the white areas on a leaf to a papery, dry consistency so you will be able to see the damage at an early stage. If your plant does exhibit damage then try to provide more shelter for it.
Hostas are also prone to weather damage if exposed to
heavy winds and rain so planting in a well sheltered spot will help
protect against this. Over winter, we suggest you leave your pots on
their side to avoid waterlogging and then freezing as this can damage
the root system of your plants (and your lovely pots).
If you are collecting miniature hostas then we recommend you pop them into containers for the first few years until they have established themselves sufficiently to compete with the other plants in your garden.

'Miracle-Gro'
warning
If you use 'Miracle-Gro' on your hostas they will become stressed, look weak and probably die back completely in the autumn never to return. |
As woodland plants hostas gain their nutrients
through the continual decomposition of rotting leaf litter. Therefore,
they do not require very much in the way
of food. If your hostas live in pots then give them a couple of feeds
of half-strength 'Tomorite' during the year but no more. All our sales
plants, and the majority of our parent plants, are grown in pots and
we apply a seaweed feed in the spring as the only feed for the year.
If your hostas are planted in the garden then the
application of well rotted manure or garden compost, when the plants
enter dormancy in the autumn, will serve them well during the winter.
Top dressing with the same in the spring, together with an application
of slug pellets will give the plants an extra boost during emergence
whilst combatting early damage by the slugs emerging from hibernation
at the same time. An early top dressing can also help protect the emerging
shoots from late frosts.
Can I split my hosta?
Yes, but we recommend you wait until the spring
and see how your hosta looks as it emerges. If the new shoots are looking
a bit crowded together then that is a sign the plant could do with splitting.
If your plant is pot-bound then it may throw up premature flower spikes
rather than produce leaves - this is a sign that the plant is stressed
as it is trying to reproduce too early in the year.
Dividing hostas is easy - details of how to do this can be found in our May 2007 newsletter and our December 2009 newsletter
What is your secret weapon
against slugs and snails?
First, determine what has damaged your plant:
- Slug damage is indicated by holes in
the leaves on emergence. The slugs that do the damage emerge from
hibernation at the same time as your hostas and the only things
on their minds is food and reproduction. They are best targetted
early.
In the past we have used Nemaslug to great effect. Indeed it gave us two seasons of control in one application. It is a common misconception that control only lasts for the six week life cycle of the nematode, since during this time the creature produces and it’s progeny take over the task, if there are enough slugs left for them. We also noticed that the nematode worked against young snails.
However, the nematode is temperature dependent. Prolonged drought or cold spells will make it necessary to re-apply.
Nemaslug is available from Nemasys
- Snail damage shows as large lace-effect
gashes in the leaves throughout the season. Snails are the most
damaging of hosta pests aside from vine weevil and you will need
to spot treat regularly throughout the growing season to combat
this pest effectively.
We have devoted a couple of newsletters to this subject:- February 2007: What to do about slugs and snails
- October 2007: Over-wintering your hostas
Our approach
We are currently experimenting with an organic product
new to the market, Redbush Mulch. Rebush
mulch is a by-product of the tea manufacturing process and
contains trace elements that act as a deterrent to slugs and snails. It is a great way of recycling what, to the tea industry, is a waste product and it could be a winner in your garden. Why not give it a go, for more information contact Fine Naturals Ltd
Alongside the redbush top dressing we also use slug pellets, simply because we cannot sell our plants with holes in the leaves. It is really important that you follow the manufacturer's guidelines when using slug pellets and we suggest the following hints to using them:
- Start using your chemical (metaldehyde-based)
or organic (iron phosphate-based, such as Ferramol)
pellets early on in the year, when the first warm weather hits.
The secret is using the product correctly...
- Use your pellets wisely, don't scatter widely
and wantonly, remember slugs and snails hunt by smell so you risk
attracting more of a problem than you need to solve.
- Keep your pellets dry by putting a teaspoonful of pellets in a jar (on its side) hidden among the foliage. This keeps the pellets effective for longer and any slugs in the vicinity will snack on the them in preference to your plants.
- Use your pellets wisely, don't scatter widely
and wantonly, remember slugs and snails hunt by smell so you risk
attracting more of a problem than you need to solve.
Using nematodes to combat the slugs and pellets to combat the snails leaves us with a little time to combat vine weevil, which is altogether a more tricky pest to deal with:
- Vine Weevil damage shows as notches nipped out along the leaf edges. This is done by the adult weevil, which feeds at night and does not fly. It’s larvae feast on plant roots to devastating effect. The larvae are white, about ½” long, with brown heads.We have found that they are most likely to cause damage in potted plants, probably because they like soft peat. To combat this we always add 20% sharp sand to our potting mix. We also take the precaution of re-potting plants we buy straight away, in case we have imported any pests.
Ordering from us
Ordering from us is easy, simply call us on 01449
711576, or email
us, with your order.
Your mail order plants will arrive by first class post, bare-rooted and ready for planting in pots or directly into the ground.
To give them the best start plant in a well prepared
humus rich soil that is sufficiently friable to ensure good contact
with the roots. Make sure they do not dry out whilst establishing themselves,
but do not over water. Removing flowering shoots for the first season
will encourage plants to concentrate their energies on producing more
crowns and strong roots.
If planting out when frost may be a problem, protect with mulch. This
is also recommended for the early emerging cultivars, e.g. Montana Aureomarginata
and plants from the Tardiana grex.

We do not send out plugs
We send out your plants ready for planting, either into the ground or in containers. We believe it is our role to ensure the plants we send you are garden-worthy, strong and characteristic. |
We have an ever-growing list of highly satisfied customers who have successfully ordered plants from us and love to tell us of their joy at receiving such beautiful plants in this way. We could list a whole bunch of bouquets but feel you should experience our mail order for yourselves. Why not give it a go?
