<\/a><\/div>\nFor those who weren’t able to get along here’s a summary:<\/p>\n
*Getting Rid of Wild Garlic<\/p>\n
This can be difficult – it has a bulb which makes chemical control less efficient.\u00a0 It is possible however to weaken the plant by strimming it in the spring or autumn (never the summer).\u00a0 Two weeks after strimming chemical herbicide in the form of glyphosphate should be applied a the correct label regulation rates.\u00a0 It is important that the regrowth after strimming should only be between 2 and 5cm in length. It will be necessary to repeat this at least twice. It is important that\u00a0 the herbicide is applied to any new regrowth which is only 2-5cm in length.\u00a0 It is the young growth that will absorb the herbicide.\u00a0 In the summer the garlic bulb is resting and will not absorb or be affected very much by the herbicide.<\/p>\n
*When is the best time to cut beech hedges into older wood?<\/p>\n
This very much depends on the health of the\u00a0 plant.\u00a0 The optimum time is April or October.\u00a0 Remember it is illegal to disturb nesting birds and therefore April may not be convenient.\u00a0 You certainly would have to complete a risk assessment to avoid disturbing birds.\u00a0 The health of the plant can be improved before pruning by feeding with a Nutra Ball at least six months before commencing any pruning.<\/p>\n
*Some information on roses<\/p>\n
The rootstock of the majority of bush and climbing roses have been improved in the last 10 years.\u00a0 This means that it is now possible to replant roses in the same ground.\u00a0 Previously there was an issue of rose replant disease which prevented new roses being planted in the same ground.\u00a0 Roses are hungry feeders, they prefer a balanced nutrition and therefore try and avoid fertilisers containing only three nutrients.\u00a0 Roses which are suffering from poor nutrition do benefit from liquid feeding with a balanced fertiliser.<\/p>\n
Mulching roses is very beneficial as it helps to prevent blackspot penetrating the soil in the autumn.\u00a0 Do remember however that chipped wood is not ideal for roses as it may contain some fungal diseases.<\/p>\n
*Wildflower Meadow considerations<\/p>\n
The key fact to remember here is that it is important to ensure the seed mix of wildflowers is:<\/p>\n
*suitable for the soil pH<\/p>\n
*has a low grass content.\u00a0 Be aware that very cheap mixes contain a high percentage of grass in comparison to the wildflowers.<\/p>\n
It’s important to ensure that the nutrition of the soil is low and it may be necessary to remove the top 15cm of soil as this contains the majority of plant available nutrients. An interesting development is the gel liquid formulations which can now be used to apply the wildflower mix.\u00a0 This is beneficial as it helps to reduce dormancy problems.<\/p>\n
Another consideration is tat in the autumn the wildflower vegetation will need to be cut and removed in order to prevent too much Nitrogen entering the soil from the decaying vegetation.\u00a0 It is however very important to cut off the seed heads of the wildflowers and lay the seed heads on the soil.\u00a0 This will help regeneration of the meadow and in addition birds enjoy the seed.<\/p>\n
The wet weather and consequences<\/p>\n
There are two major considerations here:<\/p>\n
*Physical flooding which clearly has serious consequences in damage to property and gardens.\u00a0 It is possible for grass and the majority of plants in the winter period to survive flooding for several weeks.\u00a0 The cooler temperatures will mean that respiration is reduced and plants contain a lot of trapped oxygen in their internal structure.\u00a0 The best advice here is to wait and see which plants show sings of physical damage.<\/p>\n
*High water tables and often underground springs coming through to the surface layer can often cause damage not often seen as the water is just below the surface of the soil.\u00a0 It’s still better to wait until the water level within the soil is reduced which may take up to three or four weeks from early March.<\/p>\n
It’s important to review the following:<\/p>\n
*Avoid applying plant nutrition at this time<\/p>\n
*Do not apply herbicides particularly on grass during this period<\/p>\n
*Avoid applying any fungicides on to the soil<\/p>\n
*It’s not advisable to lightly fork over the soil as this will most likely damage the root system which will take time to recover.<\/p>\n
*When planting new shrubs into soil that has recently had a high water table it is advisable to add some vermiculite into the planting hole, as this will help to prevent problems of high water table in the future around the plant.<\/p>\n
*It must be remembered that applying a lot of sand to soil that has been flooded or had a high water table is of limited value. The sand tends to wash down into the soil and in fact can cause a physical pan within the soil profile. Sand\/grit is not nutritious and therefore soil organisms tend not to move it around within the soil profile.<\/p>\n
*It’s likely that there is going to be more fungal problems on plants especially those that have been badly affected by the high water table.\u00a0 Flowers of Sulphur is a useful product to use but do remember the regulations of the Food and Environment Protection Act 1985.<\/p>\n","protected":false},"excerpt":{"rendered":"
We had a very good turn out yesterday at Wisley Horticultural Society for a half day of training with one of Wisley\u2019s experts.\u00a0 These are always very popular events that we hold twice a year.\u00a0 It gives operators a chance to spend time with each other, share their experiences and increase their knowledge. We invited … <\/p>\n
